Some anti-futurology on The Age of the Universe

Confession: although I am a futurologist and look forwards most of the time, I also enjoy pre-history. In fact, my father is Dr Gordon Pearson, who won the Pomerance Award for his contributions to archaeology, producing a calibration curve for C14 proportion against the age of a sample, thereby facilitating many other researchers’ work on ancient civilization going back 50,000 years, and who was one of the first to measure accurately the correlation between sunspot activity and climate. I inherited his time-traveler gene and conventional generational inversion was then applied.

I wrote a short piece a month or two back on the acceleration of the universe

https://timeguide.wordpress.com/2017/03/23/explaining-accelerating-universe-expansion-without-dark-energy/

I have been irritated by the bad science that has jumped illogically to the conclusion of dark matter and dark energy as the reason for acceleration. Occam’s razor needed to be used so I took it out. I noted that as galaxies expand and move further away from each other, Higgs particle flux must fall so the mass of the galaxies must fall, so their speed must increase to conserve energy. Then I moved on to work that pays my bills. So I missed a bit. If my theory above is correct (and in that regard, I should note that I have forgotten much of the Physics I learned at university, and some of the rest is now wrong anyway), then it must also be true that the universe was accelerating much more slowly in the past when the galaxies were close together, and its mass must have been much higher.

So if you assume, as I now do, that when observing red shifts today, when we are moving faster than before due to that ongoing acceleration, that we are measuring higher speeds than those light emitting galaxies had when they emitted that light, and by assuming relatively constant mass, as is also seemingly assumed, then the earlier speeds must have been far less, therefore we must be looking at too steep a curve for backward extrapolation to the beginning. Therefore the estimate for the age of the universe of 13.82 Billion years is too low. I no longer have the maths skills or physics knowledge to calculate an age that takes my theory into account, but engineer’s intuition suggests it would be 15Bn years or possible even more.

As I’ve cautioned, perhaps you should take my theory with a pinch of salt. There is much I don’t understand. But I do understand enough to know that combinations of group-think and intense focus sometimes mean that scientists overlook gorillas standing right in front of them as they concentrate on their current equations. Unlikely as it is, I might possibly be right.

Just occasionally, everyone else IS wrong.

High-rise external evacuation

A quick googling turned up this great idea, using an escape chute attached to the top of a fire crane. The chute has a fireproof external layer and people slow or speed their descent in it simply by varying their posture. Read the pdf for more details:

http://www.escapeconsult.biz/download.php?module=prod&id=26

But the picture tells all you need to know. You can see it reaches very high, up to 100m with the tallest fire appliance.

It is a great idea, but you can still see how it could be improved, and the manufacturer may well already have better versions on the way.

Firstly, the truck is already leaning, even though it has extendable feet to increase the effective base area. This affects all free-standing fire rescue cranes and ladders (suspension ladders, or ladders able to lean against a wall obviously include other forces). Physics dictates that the center of gravity, with the evacuees included, must remain above the base or it will start to topple. The higher it reaches and the further from the truck, the harder that becomes, and the fewer people can simultaneously use the escape chute. Clearly if it is go even higher, we need to find new ways of keeping the base and center of gravity aligned, or to prevent it toppling by leaning the ladder securely against a sound piece of wall that isn’t above a fire.

One solution is obvious. Usually with a high-rise fire, a number of fire appliances would be there. By linking several appliances to the ladder in a stable pattern, the base area then becomes far larger, the entire area enclosed by the combined appliances. At the very least, they can spread out across a street, and sometimes as in the Grenfell Tower fire, there is a lot of nearby space to spread over. With a number of fire appliances, the crane is also not limited to the carrying capacity of a single appliance.

If theses are specialist hi-rise appliances, one or two would carry telescopic arms to support the rescue equipment, with one or more trucks using tension wires to increase the base area.

We also need to speed up entry to the chute and preferably make it accessible to more windows. The existing system has access via a small hole that might be slow to pass through, and challenging for larger people or those with less mobility. A funneled design would allow people to jump in from several windows or even drop from a floor above. Designing the access to prevent simultaneous arrivals at the chute is easy enough, even if several people jump in together

Also, it would be good if the chute could take evacuees away from the building and flames as fast as possible. Getting them to the ground is a lesser priority. Designing the funnel so it crosses several windows, with a steep slope away from the building (like an airplane escape slide) before it enters the downward chute would do that.

Another enhancement would be that instead of a broad funnel and single chute, a number of chutes could be suspended, with one for each window. Several people would be able to descend down different chutes at the same time. with a much broader base area, toppling risk would still be greatly reduced.

If a few support arms could be extended from the crane towards the building, that would provide extra stability until their strength (or building fabric) is compromised by fire. Further support might sometimes be available from window cleaning platform apparatus that could support the weight of the rescue chutes. If emergency escape chutes are built into the platforms could even make for an instant escape system before fire services arrive.

With these relatively straightforward enhancements, this evacuation system would be even better and would allow many people to escape who otherwise wouldn’t. OK, here’s a badly drawn pic:

Fighting fires on tall buildings

Fires in tall buildings over the years have led to many improvements in designs that prevent them from starting or from taking hold, and then if they do, to slow down their spread. Thankfully they are very rare. Existing technology is also very limiting. Ground-based fire appliances can only rescue people from lower floors and can only spray water onto a few floors above that. Fire extinguishers and internal sprinkler systems can obviously help put fires out or slow them spreading if they are actually present and if a few people are willing to take risks. That there were none in Grenfell Tower is simply beyond comprehension. Negligence, incompetence and complacency don’t begin to cover what needs to be said.

However brave firefighters are, and nobody doubts their bravery, they will need better tools to do the job, they are simply not equipped to fight fires in skyscrapers such as we just had. People should not die if there are potential solutions. Some are feasible now, but I am not aware of their use.

External fires such as the Grenfell Tower fire in London recently can’t be fought fully by either internal sprinklers or ground-based hoses. We need new techniques capable of dealing with such fires. A quick googling on future fire fighting is surprisingly disappointing. Even googling future firefighting doesn’t turn up much. Most is about fancy new imaging kit or protective uniforms with embedded sensors. All great stuff, but it won’t stop another Grenfell. I’m no expert in this field, so maybe I just haven’t used the right search terms, but it shouldn’t be as easy as it is to think up solutions that are not already in use. Maybe there are good reasons why the following are not in conspicuous use yet, but I can’t think of any. None of what follows is rocket science.

Water tanks on roofs could be attached to tubing around the perimeter of the building roof, and remotely operable valves could then be used by ground crews to release water in curtains down a side of the building. Obviously capacity is finite, but after initial quenching, continuous water flow from the roof would help, however little. Large tanks could be installed if none are present to add safety to existing building with poor cladding.

A way of getting firefighting kit high up is to use the platforms provided for window cleaning. They could be lowered to below the fire and fire pumps could be put on them, or at least anchorages for steerable hoses. This does not need firefighters to be on them, they could stay below. Clearly, roof kit might eventually fail and wires might break, but meanwhile they could help alleviate the problem and buy time at the very least. If firefighter lives are not put at risk to do it, there is little penalty.

External sprinkler tubes could also be fitted that could be connected to water supplies just below and external fire. This might buy one of two floors of relative safety above and greatly reduce smoke from outside. They don’t even need to have sophisticated nozzles. All they need to do to be useful is to spray some water on some of the external fire. Even if sub-optimal, they would buy a little time.

Drones offer one potential assistance route. Two types are relevant. One is very well known already and I would expect is already in use: Conventional drones can carry cameras and other sensors to higher floors to monitor what is happening, offer assisted networking for internal firefighters, offer firefighters alternative views of the action, enable local and accurate positioning systems, and provide computer-enhanced imaging to augmented reality helmets.

Secondly, high power tethered drones could be powered by connected electrics from the ground, so avoiding the battery and power limitations of conventional drones. They could reach high floors and stay there while supporting hoses from the ground or from lower floors, and might even be able to hold pumps if ground pressure can’t be made high enough. These would offer helicopter-type functionality or lifting capacity without having to go back and forth to refill with water or fuel. Cost would be relatively high, but fire departments would not need many.

Once an external wall is made free of fire, drones and window-cleaning platforms could be used in rescues.

Obviously a lot has been written about futuristic imaging, sensing, navigation and bio-sign monitoring for firefighters, as well as deploying robotic firefighters that can work down from roofs, relatively immune to fire and smoke, so I won’t bother repeating here what is already known well. What is apparently lacking sometimes is low-tech kit and making it actually present.

If these systems are already well known but there are good reasons why they don’t feature, then I have wasted your time.

Vertical solar farms, the next perpetual motion machine

I am a big fan of hydroponics. LED lighting allows growers to deliver a spectrum optimised for plant growth and they can get many times the productivity from a square metre inside under lighting than outside. In the right context, it’s a great idea. Here is a nice image from GE Reports , albeit with pointless scanning.

I don’t think much however of the various ‘futuristic’ artist impressions of external vertical farms with trees likely to fall on pedestrians from 20 floors up. Like this one, described as an ‘environmental alternative’. No it isn’t, its a daft idea that makes a pretty picture, not an alternative.

But as far as silliness is concerned, I suspect I can see one that is coming soon: the vertical solar farm. Here is how it will work, cough. Actually two ways.

PLEASE DON’T TAKE THE FOLLOWING SERIOUSLY!

A lot of external solar panels on a building will gather solar energy (or solar paint, whatever), and that wonderful renewable energy will then be used to power super-efficient LED lights, illuminating highly efficient solar panels inside. The LED banks and solar panels will be arranged in numerous layers to make lots of nice clean energy. The resultant ‘energy amplifier’ will appear.

A more complex version will use hydroponics instead, converting the externally gather solar energy into plant material to make biofuel to make energy to power the lights during the night.

Some clever-clogs will then work out that the external panels are not needed since the internal panels will make the light to power the LEDs 24/7. People will object, but they’ll just point at the rapidly growing efficiencies of both LEDs and solar panels, especially coupled to other enhancements such as picking the right spectrum for the LEDs. How can it not work?

You know as well as I do, I hope, that this is total nonsense and will remain so. However, you also know as well as I do that some people are very easily taken in. Personally, I can’t wait to see the first claims from some Green company. I wouldn’t be all that surprised if they manage to get a development grant. It would be hilarious if something like this makes it through a patent office somewhere. Perpetual machines don’t go extinct, they just evolve.

Actually, I’m more upset that it isn’t April 1st.

Should Dr Who be a different sex or race?

Dr Who is one of my first TV memories. I even got a Chad Valley toy projector with Dr Who slides.

There seems to be a current obsession with political correctness regarding the next Doctor, so I thought I’d throw in my two pennies worth. As you probably know if you are a regular reader, I’m not a big fan of PC. I much prefer actual truth to adjusted truth, whatever it looks like.

Dr Who was originally intended to have 7 lives and when he dies, he regenerates into a new body, convenient since that allows the character to remain but a new actor to take over. Those 7 lives are now long gone, and the original 7 has conveniently been dropped from the lore ages ago. The gender of the Doctor remains male, as in the original set of books, allegedly, but there is much debate about changing Dr Who to a woman. Some people object to that.

I don’t care either way since it has become so dull and predictable and PC that I never watch it any more anyway. Any sci-fi interest has long since been replaced by blatant activism. Now there is more debate on whether Doctor should be gay or a different color. All 13 so far (though I haven’t seen the last several episodes so I might be out of date) have been straight white men. Shouldn’t he/she be black or at the very least, non-white? An interesting question, hence my blog.

We do have some base for an answer. Regenerated Doctors don’t look like their predecessors, so genes related to appearance are presumably ignored, whereas the Doctor retains the same overall biology and species, keeping two hearts for example and remaining humanoid, so many genes are acted on. Does that apply to gender? Who knows, who cares? If it is important to stick to the lore, then he should remain male. If not, then it should really be on the basis of whichever actor or actress could play the character best.

What about race then? If he was human, then why not be another race? Most humans are not white, so if the Doctor were human, and genetics doesn’t count, then gender and race should presumably be random. However, again, any story is entitled to stick to its lore. Dr Who is not human, but an alien from Galifrey, in which case, to be scrupulously fair, I’d expect regenerations to follow the statistical demographic mix on Galifrey. I’d have to say they do based on episodes that show crowds on Galifrey.

Given that the default from the original stories is for Dr Who to be a straight white male, surely it is sexist or racist or anti-straight to demand he be anything but. If the series were about ancient Egyptians, few people would be demanding Cleopatra be played by a white man.

In fact, given that the stories have all had British Doctors, since they were aimed at a British audience, then it could be argued that Doctors should follow the racial mix of the UK. Due to recent immigration, BME Brits now make up about 10% of the current population, but that proportion was much lower in the past. If we calculate the probability that all 13 Doctors would be white if each were based on the racial makeup of the UK at the time of casting, then the probability that all would be white is about 40%. Slightly less than average, but certainly not evidence for any discrimination.

If, and that’s a big if, we now make the concession that all future Doctors should be randomly chosen to represent UK ethnic makeup rather than ‘sticking to the lore’, which is important to many viewers, then obviously 50% from now on should be women and around 10% of future Doctors should be non-white, with 2% black and the rest from other BME variants.  If the average Doctor Who actor survives 4 years in the role, then we should certainly expect a woman to play the Doctor soon, but only start worrying about racial discrimination if we still haven’t seen a BME Doctor in the next 6 or 7 regenerations, i.e. by 2045. Complaining before that is just anti-white racist activism with no factual basis.

The new dark age

Utopia scorned: The 21st Century Dark Age

Eating an ice-cream and watching a squirrel on the feeder in our back garden makes me realize what a privileged life I lead. I have to work to pay the bills, but my work is not what my grandfather would have thought of as work, let alone my previous ancestors. Such a life is only possible because of the combined efforts of tens of thousands of preceding generations who struggled to make the world a slightly better place than they found it, meaning that with just a few years more effort, our generation has been able to create today’s world.

I appreciate the efforts of previous generations, rejoice in the start-point they left us, and try to play my small part in making it better still for those who follow. Next generations could continue such gains indefinitely, but that is not a certainty. Any generation can choose not to for whatever reasons. Analyzing the world and the direction of cultural evolution over recent years, I am no longer sure that the progress mankind has made to date is safe.

Futurists talk of weak signals, things that indicate change, but are too weak to be conclusive. The new dark age was a weak signal when I first wrote about it well over a decade ago. My more recent blog is already old: https://timeguide.wordpress.com/2011/05/31/stone-age-culture-returning-in-the-21st-century/

Although it’s a good while since I last wrote about it, recent happenings have made me even more convinced of it. Even as raw data, connectivity and computational power becomes ever more abundant, the quality of what most people believe to be knowledge is falling, with data and facts filtered and modified to fit agendas. Social compliance enforces adherence to strict codes of political correctness, with its high priests ever more powerful as the historical proven foundations of real progress are eroded and discarded. Indoctrination appears to have replaced education, with a generation locked in to an intellectual prison, unable to dare to think outside it, forbidden to deviate from the group-think on pain of exile. As their generation take control, I fear progress won over millennia will back-slide badly. They and their children will miss out on utopia because they are unable to see it, it is hidden from them.

A potentially wonderful future awaits millennials. Superb technology could give them a near utopia, but only if they allow it to happen. They pore scorn on those who have gone before them, and reject their culture and accumulated wisdom replacing it with little more than ideology, putting theoretical models and dogma in place of reality. Castles built on sand will rarely survive. The sheer momentum of modernist thinking ensures that we continue to develop for some time yet, but will gradually approach a peak. After that we will see slowdown of overall progress as scientific development continues, but with the results owned and understood by a tinier and tinier minority of humans and an increasing amount of AI, with the rest of society living in a word they barely understand, following whatever is currently the most fashionable trend on a random walk and gradually replacing modernity with a dark age world of superstition, anti-knowledge and inquisitors. As AI gradually replaces scientists and engineers in professional roles, even the elite will start to become less and less well-informed on reality or how things work, reliant on machines to keep it all going. When the machines fail due to solar flares or more likely, inter-AI tribal conflict, few people will even understand that they have become H G Wells’ Eloi. They will just wonder why things have stopped and look for someone to blame, or wonder if a god may want a sacrifice. Alternatively, future tribes might use advanced technologies they don’t understand to annihilate each other.

It will be a disappointing ending if it goes either route, especially with a wonderful future on offer nearby, if only they’d gone down a different path. Sadly, it is not only possible but increasingly likely. All the wonderful futures I and other futurists have talked about depend on the same thing, that we proceed according to modernist processes that we know work. A generation who has been taught that they are old-fashioned and rejected them will not be able to reap the rewards.

I’ll follow this blog with a slide set that illustrates the problem.

Trump’s still an idiot but he was right to dump Paris

Climate change has always been in play. It is in play now. Many scientists think that the rise in global temperatures towards the end of the 1990s was largely due to human factors, namely CO2 emissions. Some of it undoubtedly is, but almost certainly nowhere near as much as these scientists believe. Because they put far too much emphasis on CO2 as the driving factor, almost as a meta religion, they downplay or refuse to acknowledge other important factors, such as long term ocean cycles, solar cycles, and poorly model forests and soil-air interchange. Because they rely on this one-factor-fits-all explanation for climate changing, they struggle to explain ‘the pause’ whereby temperatures leveled off even as CO2 levels continued to rise, and can’t explain why post El-Nino temperatures have now returned to that pause level. In short, their ‘science’ is nothing more than a weak set of theories very poorly correlating with observations.

A good scientist, when confronted with real world observations that conflict with their theory throws that theory in the bin and comes up with a better one. When a scientist’s comfy and lucrative job depends on their theory being correct, their response may not be to try to do better science that risks their project ending, but to hide facts, adjust and distort them, misrepresent them in graphs, draw false conclusions from falsified data to try to keep their messages of doom and their models’ predictions sounding plausible. Sadly, that does seem to me and very many other scientists to be what has been happening in so-called climate science. Many high quality scientists in the field have been forced to leave it, and many have had their papers rejected and their reputations attacked. The few brave honest scientists left in the field must put up with constant name-calling by peers whose livelihoods are threatened by honesty. Group-think has become established to the point where anyone not preaching the authorized climate change religion must be subjected to the Spanish Inquisition. Natural self-selection of new recruits into the field from greens and environmentalists mean that new members of the field will almost all follow the holy book. It is ironic that the Pope is on the side of these climate alarmists. Climate ‘science’ is simply no longer worthy of the name. ‘Climate change’ is now a meta-religion, and its messages of imminent doom and desperate demands for urgent wealth redistribution have merged almost fully into the political left. The right rejects it, the left accepts it. That isn’t science, it’s just politics.

Those of us outside the field have a hard time finding good science. There are plenty of blogs on both sides making scientific sounding arguments and showing nice graphs, but it is impossible for a scientist or engineer to look at it over time and not notice a pattern. Over the last decades, ‘climate scientists’ have made apocalyptic predictions in rapid succession, none of which seem ever to actually happen. Almost all of their computer models have consistently greatly overestimated the warming we should have seen by now, we should by now rarely see snow, and there should be no ice left in the Arctic. Sea levels should be far higher than they are too. Arctic ice is slightly below average, much the same as a decade ago. Polar bears are more abundant than for several decades. A couple of years ago we had record ice in the antarctic. Sea level is still rising at about the same rate as it has for the last 100s of years. Greenland is building more ice mass than ever. Every time there is a strong wind we’re told about climate change, but we rarely see any mention of the fastest drop in temperatures on record after the recent El-Nino, the great polar bear recovery or the record Antarctic ice when that happened. It is a one way street of doom that hides facts that don’t play to the hymn book.

In a private industry, at least in ones that aren’t making profits from climate change alarmism or renewable energy, like Elon Musk’s car, solar power and battery companies for example (do you think that might be why he is upset with Trump), scientists as bad as that would have lost their jobs many years ago. Most climate scientists work in state-funded institutions or universities and both tend towards left wing politics of course, so it is not surprising that they have left wing bias distorting their prejudices and consequently their theories and proposed solutions.

Grants are handed out by politicians, who want to look good and win votes, so are always keen to follow policies that are popular in the media. Very few politicians have any scientific understanding, so they are easily hoodwinked by simple manipulation of graphs whereby trends are always shown with the start point at the beginning of the last upwards incline, and where data is routinely changed to fit the message of doom. Few politicians can understand the science and few challenge why data has been changed or hidden. A strong community of religious followers is happy to eagerly and endlessly repeat fraudulent claims such as that “97% of scientists agree…”, mudslinging at anyone who disagrees.

Even if the doom was all true, Paris was still a very bad idea. Even if CO2 were as bad as claimed, the best response to that is to work out realistically how much CO2 is likely to be produced in the future, how fast alternative energy sources could become economic, which ones give the best value per CO2 unit until we get those economic replacements, and to formulate a sensible plan that maximizes bang per buck to ensure that the climate stays OK while spending at the right times to keep on track at the lowest cost. In my 2007 paper, I pointed out that CO2 will decline anyway once photo-voltaic solar becomes cheap enough, as it will even without any government action at all. I pointed out that it makes far more sense to save our pennies until it is cheaper and then get far more in place far faster, for the same spend, thereby still fixing the problem but at far lower costs. Instead, idiotic governments in Europe and especially the UK (and now today May vowing to continue such idiocy) have crippled households with massive subsidies to rich landowners to put renewable energy in place while it is still very expensive, with guarantees to those rich investors of high incomes for decades. The fiasco with subsidizing wood burning in Northern Ireland shows the enormous depths of government stupidity in these area, with some farmers making millions by wasting as much heat as they possibly could to maximize their subsidy incomes. That shows without any doubt the numerical and scientific public-sector illiteracy in play. Via other subsidies for wind, solar, wave and tidal systems, eEvery UK household will have to pay several hundreds of pounds more every year for energy, just so that a negligible impact on temperatures starts to occur neglibly earlier. Large numbers of UK jobs have already been lost to overseas from energy intensive industries. Those activities still occur, the CO2 is still produced, often with far lower environmental and employment standards. No Gain, lots of pain.

Enormous economic damage for almost zero benefit is not good government. A good leader would investigate the field until they could at least see there was still a lot of scientific debate about the facts and causes. A good leader would suspect the motivations of those manipulating data and showing misrepresentative graphs. A good leader would tell them to come back with unbiased data and unbiased graphs and honest theories or be dismissed. Trump has already taken the first step by calling a halt to the stupidity of ‘all pain for no gain’. He now needs to tackle NASA and NOAA and find a solution to get honest science reinstated in what were once credible and respected organisations. That honest science needs to follow up suggestions that because of solar activity reducing, we may in fact be heading into a prolonged period of cooling, as suggested by teams in Europe and Russia. At the very least, that might prevent the idiots currently planning to start geoengineering to reduce temperature to counteract catastrophic global warming, just as nature takes us into a cooling phase. Such mistimed stupidity could kick-start a new ice age. To remind you, climate scientists 45 years ago were warning that we were heading into an ice age and wanted to cover the arctic with black carbon to prevent runaway ice formation.

CO2 is a greenhouse gas. So is methane. We certainly should keep a watch on emissions and study the climate constantly to check that everything is OK. But that must be done by good scientists practicing actual science, whereby theories are changed to fit the observations, not the other way around. We should welcome development of solar power and storage solutions by companies like Musk’s, but there is absolutely no hurry and no need to subsidize any of that activity. Free market economics will give us cheap renewable energy regardless of government intervention, regardless of subsidy.

We didn’t need Kyoto and we didn’t need Paris. Kyoto didn’t work anyway and Paris causes economic redistribution and a great deal of wastage of money and resources, but no significant climate benefit. We certainly don’t want any more pain for no gain. It is right that we should still help poor countries to the very best of our ability, but we should do that without conflating science with religion and politics.

Trump may still be an idiot, but he was right on this occasion and should now follow on by fixing climate science. May should follow and take the UK out of the climate alarmist damage zone too. Making people poor or jobless for no good reason is not something I can vote for.
