Mars

“But I don’t want to live on Mars”

September 21, 2017 — leslie dean brown

I’m hoping one or more of the 2000+ billionaires in the world are reading this…

Because even the richest people in the world, all the current billionaires –even future trillionaires– cannot afford to maintain their current lifestyles, as they do here so nicely, except on the planet Mars.

Where do all the rich and famous people go on holidays? I’ll tell you were they all go. They go to the one place in the world that literally “exudes luxury”. And I’ll give you a hint: it’s not Monte Carlo (that’s for people that spend money).

¹ – Bora Bora, in French Polynesia. They stay in overwater bungalows costing upwards of US$5,000 a night. That’s where they go. They take a few steps down a little ladder and snorkel right off from their little balconies. Isn’t that wonderful?

And call me strange, but all of those luxurious resorts encircling Bora Bora look absolutely nothing like… well, bloodywell anywhere on that dusty little shithole unfortunate sister planet of ours, Mars². It’s a completely vacant, crappy, dry, dusty monotone brown little shithole. And I think we have to ask ourselves “why indeed is Mars so vacant?”

And it’s going to be a L O N G time before it even remotely starts resembling somewhere like any 5+ star resort on the “just-the-right-size-mother-bear-planet-Earth”. If there’s one thing I know rich people can’t stand, it’s being in a crap environment. That’s why they pay extra to wait in lounges at the airport. Or why they have to be located in a different section of the plane. Or a different plane altogether. Because to do otherwise would be depressing. And if humans can’t stand one thing, it’s “not being happy”.

Then let this serve as an advanced warning to you, future trillionaire: the rest of us just aren’t leaving Earth so that you can stay and enjoy it around here with all your lakes, rivers, oceans and surf beaches.

I for one am not living on Mars, either voluntarily or forcibly. No. And neither are my non-existent children. This mass exodus of people in the direction of “Earth to Mars” is just not going to happen. There’ll be the bloodiest revolution in the history of mankind before that happens.

Why? Because far from thinking “Mars is going to be ‘fun’ “, I think it would be even more boring than a long-term jail sentence.

The value of NAT and ENV shares on the the global stock exchange.

August 18, 2017 — leslie dean brown

Here’s the kind of thing you see when you hang out on LinkedIn for a while:

RECAP FOR THOSE I LALA LAND THE MARKET HAS BEEN ON FIRE BECAUSE OF TRUMP UP 2500 POINTS IN 6 MONTHS MOST IN THE FIRST 60DAYS NOW OMG DOWN 200 BECAUSE OF THE SPIN OF WORDS BY THE MEDIA…THE TRUE AMERICAN ENEMY IS BLM OBAMA CLINTONS AND THIS F… UP MEDIA GIVE TRUMP A BREAK AND SUPPORT HIM STOP WASTING HIS TIME DEALING WITH THE STUPIDEST PEOPLE ON THE PLANET AND THERE BS STOP THE HATE NOW WE ARE ONE AMERICAN — Mike Pienciak

And here is my response to that:

Did you see the stock price for NAT shares though, since Trump got in? NAT shares are down. Way down. And when I say NAT, I don’t mean “Nordic American Tanker Ltd” on the NYSE. I mean NAT, on the global stock exchange, the GSE.

ENV shares are down too! Once again, I don’t mean “Envestnet Inc”. I mean ENV, on the global stock exchange, the GSE.

And isn’t it telling of business today that NYSE:ENV and NYSE:NAT do not represent nature or the environment? Quite the opposite. In actual fact they represent gas pipelines and supermax oil tankers, respectively.

Every time the Nasdaq, the S&P, the Dow jones go up, GSE:NAT and GSE:ENV invariably go down³. Way down. I think it’s because we don’t know any other way.

Maybe the only reason the stock market “is on fire” is because Mr. Trumpet wants to abolish the EPA? Maybe it’s very telling of business today. That while stock markets are, as you say, “on fire”, the Earth is figuratively burning up also.

The trouble is this: when GSE:NAT and GSE:ENV go down, all other stocks will soon follow. This should be like a law already.

It’s not all about the stock market. Do you know WHY there is not stock market on planet Mars or planet Venus? Because there is no breathable atmosphere. So maybe “business at all cost” types should consider that before their next next trade? You know, invest in something other than money?

If you could measure the worth, the market capital of GSE:NAT and GSE:ENV, it would put the rest of the worlds’ stock exchanges to shame. If we had to pay for these services, humanity would be bankrupt. Bankrupt I tell you! Bankrupt!

Traditional economic stock markets are all but a meaningless evaluation. All of them incorrectly report the true value of the Earth’s assets. If our environment cannot even be maintained, then one must ask the next logical question: just how ‘sustainable’ are “sustainable business models”?

By the way, I’m not here to make friends. I’m not here to get more connections. Or leads. Or clients. I’m here to make people think. Clients will always be there, biodiversity won’t. 2c

Oh and it is ‘their’. The word you are looking for is their, not there.

The Paris accord discord.

June 3, 2017 — leslie dean brown

Can we talk about climate change Mr Trumpet?

Rich, uneducated people almost never believe in climate change. Because I think the way they see it, “climate change” might as well be called “lifestyle change”… and we all know people don’t like lifestyle adjustments. Especially if it means downgrading them.

Oh and by the way, yes I’m fuckin’ FURIOUS alright! About this latest Paris agreement you bombed out on. You fucking-welldropped out of it, you pathethic small-handed fake-tanned little wanker! ⁴

Now if I had have known 22+ years ago that the president of the United States of America was going to be this #tangerinefuckknuckle, to coin a phrase, I never would have taken up my university on their offer to study science in the first place. I mean why bother?!

Why bother trying to be part of the intelligentsia? Or is that spelled ‘intelligencia’? Never mind. Anything but listen to “the clever people”. If the amount of clout and respect we recieve from fossil-fuel undivested bury-your-head-in-the-sand-and-the-problem-will-go-away complete FUCKWIT types is next to zero. I would have studied a creative field like art or design instead, way back then, if I had have known.

“The rest of the world applauded when we signed the Paris Agreement. They went wild. They were so happy — for the simple reason that it put our country, the United States of America, which we all love, at a very, very big economic disadvantage.” — Donald Trump

No, Mr Trumpet, no. Wrong! We cheered because the bonds in every single carbon dioxide molecule exhibit antisymmetric stretching and bending resonance modes at frequencies of 2350cm⁻¹ and 670cm⁻¹ respectively. We cheered because your country emits approximately 71,000,000,000,000,000,000,000,000,000,000,000,000 of these molecules every single year.

And I mean, shiiit, we could stand to lose money here people. MONEY! All those people in mining, construction, manufacturing, engineering, logistsics, transport. So we better put the economy first. Jobs first. America first!

But who’s fucking atmosphere is it anyway? America’s? No, we all share the exact same atmospheric coating —thin as it is.

Is there some great big motherfuckin’ hermetically-sealed compartment bigger than the USA that I don’t know about, protecting the likes of North America from extreme weather events that we know will happen? Because the last time I looked, those tropical cyclones whupped your Eastern seaboard arses! That’s right. And you couldn’t run and hide, you had to shut up shop, board everything up and close all business. That sure turned out to be great for Florida’s economy, didn’t it now?

And it turns out rich people should be a lot more worried that they are about this too. For one thing they love living on low-lying coastal regions. But even though they might be able to afford to move, their hard-working employees won’t be able to afford to, will they? Less profit for you then!

If there’s one thing scientists don’t like, it’s uncertainty. And see, that’s half the problem. Isn’t it? One or two degrees might not seem like a lot, but then, it isn’t, is it? What we worry about isn’t one or two degrees of warming over the whole surface of the Earth. That’s the average. The variance in the temperature peaks and troughs could be much higher and lower, for example. What we worry about is some parts getting hotter than average by 8-10 degrees. What we worry about is some parts getting colder than average by 8-10 degrees. If that happened, the average temperature would still be the fucking same! But that doesn’t mean that it’s okay. Right?

What we worry about is chaotic changes in weather patterns. What we worry about are tipping points. What we worry about are graphs that spike up and down like a fuckin’ yo-yo. Because that would be far worse than any global warming. If one year the planet was freezing cold like Mars and the next one it was like fuckin’ Venus. That’s not good for crops for one thing. If there is only one planet Earth, and we can’t afford to downgrade this and wait fir the end of the experiment. We have to intervene now. NOW!

If there’s one thing scientists fear, it’s losing control of nature. So up until now, we’ve always had answers for you. But if you dumbarses don’t start to listen, then what the hell can we do about it later on? When it’s too late? Nothing. You’ll be like “Oh you should have warned us decades ago that it was worse than we thought. If it was that serious, why didn’t you jump up and down and shout out about it way more?”. And we’ll be like: “Well we told you, we told you so and you didn’t listen. You just kept on buying great big diesel trucks instead of looking for a way out.”

We should build a wall alright. We should build a 55-ft high wall, and all of the people who think our actions don’t/can’t/won’t have any global effect or climate consequences should have their name co-moulded into that fuckin’ wall for the sake of posterity. So when the world really does start to fuck up, future civilisations can have those people to thank for inheriting such a fucked up little world.

What scientists fear most.

March 25, 2017 — leslie dean brown

I don’t even think this debate is merely about “global warming” anymore…

I think it’s more about whether you believe humans can alter the environment at a global as well as a local scale. I mean, all of us can accept that even cockroaches and rats can change their local little jaunts easily enough…

(either inadvertently and/or purposefully; it doesn’t really matter for the sake of this argument whether the changes are intended or not)

There is no question that we alter things at a local scale. We can directly manipulate the atomic, molecular and microscopic scales. We manipulate things at the ‘macro’ scale, too (the scale of what we can see without the aid of a microscope). We make things, change things, on the scale of millimetres, centimetres, metres, even kilometres. We make runways for instance. How long are they? Right?

Here’s a timely reminder — Earth’s atmosphere is only about 10km ‘thick’. I’m sure most people don’t stop to appreciate this on their morning or afternoon commute: most people travel more in one single day –be it driving a car or walking in the Ethiopian desert– than the Earth’s atmosphere is ‘deep’. They most likely travel at least this distance every single day of their lives, perhaps more.

One only needs to look around a city, any city, to know that the human civilisation built it. We most definitely changed it. Why? Because it doesn’t look like it did before humans settled there, that’s why. Isn’t it obvious? Before that, it was a forest or a jungle, a river’s edge or a peat bog.

And so we continue to dam rivers and build bridges. We build skyscrapers and oil tankers and cruise liners. We construct entire airports offshore.

We tear down forests and we mine the Earth. At every and any opportunity. Why? To make it more ‘comfortable’ for ourselves. We spew out all kinds of gases and chemicals into our waterways and our atmosphere. And somehow, miraculously, none of this can even remotely alter something so basic as “the average temperature”. Somehow “that’s impossible”⁵.

At what point along the size scale do people go from accepting that “yes absolutely humans can and do cause local changes in the form of urbanisation” to becoming ones of “oh no, humans are too puny to have caused this, this is god’s realm, carry on” in someone’s mind? At what scale? Where exactly do they let go of reality?

Here’s the thing that most people don’t seem to understand or comprehend: if you do enough “local-scale things” all around the planet, then it has to change at a global scale as well. It has to! Indeed, there really is no black and white distinction between ‘local and global scales’. The cosmos presents a continuous scale, all the way from the very tiniest subatomic particle (and probably smaller) right the way through to galaxies and beyond. And I don’t care what you think you want to believe, each scale does affect the other.

Man is not exempt from the effects of any of these scales (at either the very large-scale end, the very small end or anywhere inbetween). All scales can potentially be ‘dangerous’ to us. We have radiation, we have poison, we have knives, we have trucks crashing into things, we have nuclear bombs. And we also have something else. Something else we can’t quite control as well. The environment: the oxygen in our atmosphere, fresh water, food (and to a lesser extent, gravity). Each represents a different scale. And the presence or absence of each one can equally kill, albeit at different timescales.

There is simply no getting around it… “do enough shit” to the surface of this planet, any planet, and you’ll most likely fuck it up completely rather than make it only slightly ‘better’⁶

Whether carbon dioxide gas, or any other compound, it really wouldn’t matter what is causing it either, would it? Would it matter to people if it were a different compound such as methane, krypton or something else they’ve never even heard of? Would that help them understand what is going on with vibrational modes of this molecule at infrared frequencies?

Actually, surprisingly, I think the answer to that question is: “it depends”. I think the answer lies in how much this presence or absence of whatever it is we have to give up contributes to our current lifestyle. And I think we all know that we are far less likely to give up our ‘comforts’ than if it’s something we never (or rarely) use anyway.

If we don’t have much to give up, like with CFCs for example (because we simply used a spraycan with a different propellant inside of it), then by all means “let’s do this right now, starting today”. The Result? Ozone hole partially closed already.

A scientist might say that our reluctance to change is “inversely proportional” to the amount that it affects our present and future lifestyle. Lots to give up? Climate change = fake news. Not real. Not happening. Nothing to give up? No reason why it couldn’t be true.

On the other hand, if you’re talking about giving up the power of your very own automobile, reducing your electricity consumption, buying and using less stuff, travelling less, or just even generally using less and less technology instead of more and more — then on second thought, “perhaps not quite so fast”. Right?

Do you know what scientists fear most? Do you know what scares scientists absolutely shitless? Well they might not know it, but I think all scientists inherently fear that one day we’ll lose control of nature. Because right now, science can control nature (well sort of).

Just take a look at this extract from a paper which a climate change denier recently shared with me. It talked about the influence of solar activity on anthropogenic climate change. He obviously was only reading the abstract and conclusion, because this is what the paper said about half way through. Keep in mind, this is from a paper that is leans towards being more critical/skeptical.

“Most of the climate scientists agree, that an increasing absorption with rising CO2 concentration alone, as discussed in the previous subsection, would only moderately contribute to any global warming. The greater worry, however, is that already smaller perturbations, as caused by the GH-effect, may initiate further side effects, which could significantly amplify the primary perturbation and even result in a total destabilization of the quasi equilibrium conditions of EASy. These side-effects are known as feedback processes, which on one side can amplify an initial deviation (positive feedback) or on the other side can also attenuate this deviation (negative feedback).”

The words “total destablisation of quasi-equilibrium conditions” sure doesn’t sound good for planet Earth. Basically, in English it means that everything goes completely haywire!

Now we don’t want you to panic. But quite frankly, it’s fast getting to that point. Because species are becoming extinct all over the place… and it’s an understatment to say that biologists, entomologists, and soil scientists are not happy about that.

I think to many people, technology may make it seem like “we can do whatever the fuck we want, however we want, whenever we want and wherever we want” and still we’ll all be okay. That no matter what happens, scientists will be smart enough to “figure a way out it”. I mean heck, “who ‘invented’ the ipad?”. People. People are smart. Right?

Wrong. Because even today, in the ‘modern age’ (whatever that is) we don’t have to create our own gravity, sunlight, air pressure, oxygen and water. Do we?

And somehow –some truly clueless, ignorant people– think that “everything’s going to be alright, Jack”. Maybe because it always has been. Maybe because they don’t have a very good imagination about the future. Maybe because they are ignorant. Or maybe they believe in some kind of higher power and that “man can do no harm”, that man’s job is to “work and be more productive”.

These “deniers” generally retort: “the sky is falling, the sky is falling” whenever anyone becomes even remotely ‘alarmist’. As if all alarms are false ones. Even if the alarmists do have a higher IQ.

But I really would really like to see those very same [science] deniers in another, very different, scenario. Say they we have organised a tour of a nuclear power station for them. Just say. Would they stick around, for example, if/when a nuclear scientist is yelling at them: “THE CORE IS GOING INTO MELTDOWN, GET THE FUCK OUTTA HERE!!!!!”. Would they be hanging around the containment building, tardily and proudly proclaiming “the sky is falling, the sky is falling!”? Would they be so quick to make a cup of coffee in that instant? Or would they, far more likely, heed the scientists’ advice and flee their sorry arses right on out of there as fast as their legs could carry them? Yes I think the latter.

Or maybe I reall am missing something. Maybe we really are puny. Maybe. Maybe we are so fucking puny, nature will continue to evolve and adapt all around us.

But then I recall biololgists tellings us that the less biodiversity there is, the slower nature recovers from all kinds of change.

Is humanity ready for Elon Musk’s Mars mission?

January 10, 2017 — leslie dean brown

🙂

Going to Mars is harder than getting to the top of Mt. Everest. And I don’t see anyone living way up there on the summit.

Dear Mr. Musk, I think a better way of doing it is to genetically engineer bacteria to produce an atmosphere first, over successive generations. Generations as in plural, i.e. more than one.

One simple reason we’re where we’re at today is because nature has provided us with abundant raw materials. It started with the use of solar powered materials (by that I mean twine and timber). There are no solar powered materials on Mars. No trees. No forests. The most efficient materials (in terms of energy required to produce them) are natural materials, because they convert sunlight directly into… materials. No heat required. All other synthetic materials require lots of energy to produce.

If I were hired to do a materials feasibility study, I would have to rule that it is “not yet feasible”. Even with the invention of “Martian concrete”. How are are you going to make hermetically sealed living quarters out of that slop? Are they going to be shoveling Martian concrete… wearing gas masks? Builders can’t even get that right here on Earth with abundant food, water and a 21% oxygen level. None of that over there. Is there?

My point is that nature is still subsidising all of humanity’s activities, even today. So we would be going backward centuries, millennia even. You can’t even light a fire on the planet Mars. What good is that? People today would be bored out of their minds.

IMHO, trying to colonise Mars now is going to be 10x slower, 10x more expensive and 10x more boring than expected. Besides, if we were all living on the planet Mars now under domed little roofs, I’m sure we’d all want to live here –on the interesting planet– not there.

And the way production and manufacturing has worked up until now is this: several tens of thousands of years ago, wood and other natural, local materials were first used to to usher in the ceramic/pottery era … which was then used to usher in the bronze era … which was then used to usher in the iron era … which was used to usher in the modern information & nanotechnology era. We have always had to work our way up the material chain. And all the while, well, nature herself has been subsidising us all along. With the really important things like food and oxygen.

My point is, we didn’t just jump straight into making gigahertz computers, we had to work up to it. Slooowly.

So it would be a bit like taking our current technology back in time, to the ancient Egyptians. Now to the big question: How much technology would we need to take to them to advance the rest of that civilisation in one big, massive jump forwards?

So right along those lines, here’s a quick thought experiment: say you take a smartphone back in time to the ancient Egyptians. Does anyone truly think that that would be ‘enough’ to start making mass-produced batches of smartphones right next to the pyramids o Giza? Well in case it isn’t clear already, it’s not.

Because first of all, there are no microscopes to even see what is going on inside that phone to even reverse-engineer that technology. And in order to get the microscopes, one has to first invent glass. And to do that, one needs polishing machines. Which requires motors. Axles. Bearings. Magnets. Copper wire. Electrical insulation. Ok. Now that we have that, on to making the components. Capacitors require tantalum. Touch screens require indium. Tin. Oxygen.

What are resistors made of? Carbon. Nichrome wire. Plenty of that here on Earth… not so much on Mars. Okay, not to be the pessimistic one, what are circuit boards made of? Fibreglass. What is the matrix made of? Plastic. What are plastic buttons and the casing made of? Plastic. No oil wells on Mars yet. Shit. Where is the nearest fibreglass factory? Where is the nearest plastic factory? Yellow pages? Hmmm. This is going to be more difficult than we first thought, isn’t it?

Never mind, we will continue, however.

What about the semiconductors used in all those tiny transistors? Germanium. Germanium is hard enough to get our hands on here, let alone there (with no atmosphere). Do you see my point? And there are many other elements required too. Where is the nearest gadolinium mine? Earth, that’s where.

Where are the silicon mines and purifying factories located on Mars? Nowhere. Don’t we need vacuum rooms for that as well? Well, yes. Why? Because the ‘vacuum’ that is the Mars’ atmosphere… is simply not ‘vacuumy’ enough. We need an ultra-high vacuum to achieve high-grade 99.999% purity silicon. So we are going to take vacuum pumps with us now are we? They’re pretty heavy. And every scientist already knows— you can never ever get down to an ultra-high vacuum with only one type of vacuum pump. Better make that rocket booster a bit bigger for the takeoff. Still more rocket fuel than expected.

Ahh yes, there is this one new technique to manufacture 99.999% silicon from 84% ferrosilicon. Except that it requires a sol-gel lab. Glassware at the very least. Liquids. Centrifuges. Magnets. Neodymium. Oh well.

So what you space futurists are basically telling me is that you would have to bring all of these starting materials… from Earth first… simply in order to “get going”.

I can’t even yet buy a fucking Mars bar on the planet Mars. And we are already talking about colonising that motherfucker?

“For a better world?”
Which world exactly?

Timely reminder: there is a whole freakin’ industry required to produce computers and everything else from their raw materials. A whole level of industry. Everything from mining equipment to extraction facilities, to manufacturing centres and clean rooms. The only way a Mars colony could ever be truly self-sustaining, is to take several different types of factories –yes I said entire factories– with us.

And everyone already knows small factories are not as efficient as larger factories, right? So in case the purpose of this post isn’t clear yet, what is the fucking point of this new Mars mission?

And now to my second big question: if we already know that the efficiency of production there is going to be WORSE than what it is here. If getting there fuck’s up this planet further, why even go?

Why go? Because we can? Does that mean we should? This goes without saying, but just because we can do something does not mean that we should. Simply being able to do something does not make it ‘better’.

And is that what we have been planning to do all along? How much jet fuel would that require I wonder? Eh?

So I think we better not bite off more than we can chew. I think the space mission to Mars, this whole redent “we need to colonise Mars” thing, is a bit like the 1960s space race, but this time between billionaires/trillionaires not just superpower states. Albeit with comparable 1950s era-like naïvety. That’s what I think of it. Those futuristic images depicted by artificial intelligence are just about as stupid and naïve as some 1950s era visions of space stations and shit. And here we are in the year 2025 (which really does feel like “the future” in many respects, at least to some of us older people) and there are no space stations or . Except today we really should know better.

Now, I am not saying that we are not ‘clever’. I am not saying that we are not ‘advanced’. I am not saying that it can’t ever be done. And I’m not saying that it won’t ever be done.

But what I am saying is that it is definitely going to be harder than we think. Not to mention less efficient. And ultimately worse for planet Earth.

We are not yet even fully self sustaining here on Earth, with water that falls freely from the sky, with oxygen that is freely available and with food that grows all by itself.

And people still want to start an entire manufacturing operation on another planet, with absolutely none of that already over there?

UPDATE:
Just today, Elon, rather foolishly said this:

“We need to transport about a million tons of cargo in order to make it sustainable and about a million people or more. Civilization will branch off when Mars can self sustain even if shipments from Earth stop coming. I think there might be a case where the future Mars citizens come and help Earth one day when we’ll need it. Once we have a Mars civilization we can expand to the rest of the solar system. Then we go from being a multi planetary civilization to a multi stellar civilization and start learning more about if we’re the only life out here.” — Elon Musk

Firstly, not even Elon Musk could afford to transport a million tonnes of cargo to the planet Mars any time soon. And I’d be willing to bet that not even the top 1% rich people couldn’t afford it either, even if they pooled together all of their wealth, combined and accumulated it. It’s just… not happening okay. So forget it Elon.

And here’s a scary few final thoughts. The only way it would work, I think, is if ‘people’ are genetically modified and specifically adapted to live there. If they can breathe thinner air, if they have different shaped noses to filter out the Martian dust (well that’s assuming they won’t need a space helmet), thicker UV-protected skin (also prevents or lessens dehydration), different digestive tract to cope with different food sources perhaps, lesser water requirements than humans.

Would these beings then resemble humans at all then? Would we even want to go in that direction? It opens all sorts of ethical questions and moral dilemmas.

And sooner than “future Mars citizens come and help Earth one day”, I think much more likely to happen, if you look at past historical events and squabbles over mineral and material resources, food sources and land, is that the new Martian colony, once it starts to get established that is, becomes very different from our own, generates its own [different] cultures, priorities, values and traditions. Because it is more isolated and segregated and this is always what happens with any new colonies. They diverge. And then it, they, whatever they is, starts to see us –all of humanity back here on Earth– as a threat to its own survival, a direct threat to its very own existence, and goes on to attack us. To declare war on Earth. Or vice versa, and we go to war with them. It would be like creating Frankenstein’s monster. Why go there? Why do it? We may live to regret it one day.

I certainly don’t think it’s right. We need to fix our home and make our way of life more sustainable first before galavanting halfway off across the Solar System and spoiling other planets with our man-made synthetic junk.

Elon mentioned something about dinosaurs not having spaceships. Well dinosaurs were some of the most successful organisms to roam the Earth. They were around for hundreds and hundreds of millions of years. We really shouldn’t insult that longevity.

Just a reminder that those big extinction-event level asteroids are very few and far between, happening every few hundred million years or so. If Elon is so worried about apocalyptic asteroids striking the Earth one day and completely wiping us all out so to speak, why doesn’t he choose to focus on that actual threat –the asteroids– instead of this whole Mars colony thing? Wouldn’t it be smarter to concentrate on asteroid detection and elmination device instead? Wouldn’t that be a lot simpler and, well, cheaper? It would. Well I’ll answer my own question, yes it would. That would be a much cheaper insurance approach to human civilisation than striving for some ridiculously costly non-practical and non-workable “planet B” option.
