Trees being uprooted by sinkholes tend to be falling into the hole, not away from it. It's hard to see in the photo, but that tree looks like it's had most, but not all leaves blown off it. As for where the ejecta vanished to, it looks like where it vanished to is the area immediately around the crater. We don't have any sort of before and after picture or a picture of another part of the same wooded area, but the part that we can see seems to be all dirt except for where there are taller trees. It might be the case that there's normally nothing but bare dirt visible, or it might be the case that all the ground covering vegetation is covered in the thick layer of ejected dirt. There also seem to some loose, recently deposited, rocks outside the crater.

The part where you said "If the Soviet Union had managed LEO or the moon, do you think they would not have used it?" is the confusing part. It's confusing because you seem to have written it from a parallel universe where the Soviet Union never "managed LEO". If by "managed" you meant using taking command of LEO militarily, then the sentence in question is a tautology and one wonders why you even wrote it.

The article you linked to didn't say that Tesla drive units fail after a year. It said that the warranty used to be 8 years or 125,000 miles and that they've just extended it. There were a few anecdotes provided, but the article itself admitted that the source was inherently biased. So, basically, car parts wear out and some cars are defective from the factory. True for cars whether they're gasoline, diesel, LPG, electric, etc.

I'm sorry, you're attacking Musk because car parts wear out eventually? And he's extending the warranty for some of those parts?

This is sort of a confusing sentence. The Soviet Union _did_ manage LEO in just about every way you can "manage" LEO. They also got probes, but not people, to the moon.

Europa is probably a non-starter due to the high radiation, but Callisto gets two orders of magnitude less and Ganymede about three orders of magnitude less than that.

If their method requires 50 people to move a 2.5 ton stone block at .5 meters per second, why not just use some poles and yokes and just have the 50 men pick up and carry the stone at twice that speed? That's 50 kilograms each. Heavy, sure, but not more than a worker can carry. Obviously the rarer, heavier stones would require other techniques anyway.

In the spirit of pedantry I feel inclined to point out that what you say would only be the case if the "hill" is a 90 degree cliff.

From the article you link to:

So, it looks like he wasn't a fan of rocketry in general, which wasn't really particularly visionary of him in retrospect.

Considering that you are apparently hallucinating praise that doesn't exist in the GP's post, I'm going to say that you may indeed be a nutbar.

It's not necessarily as bad as you make it out to be. Let's say that you have a hemispherical dome covering 4.3 square miles, which I think is what the summary is trying to say. That's a diameter of 3766 meters and an interior volume of about 14 billion m^3, which is something like 17.15 billion kg of air. It's around 1000 joules per degree celcius for each kilogram. So, if you start with a very nasty 45 degrees celcius and get it down to a comfortable 20 degrees celcius, that's 428 terajoules. Obviously Air conditioning is not perfectly efficient. We'll assume an EER rating of 13 for the air conditioning, which may actually be a bit low for a huge commercial system. That's about 38%, so it would take 1.121 Petajoules. Let's say we're powering by gasoline. There's around 120 megajoules per gallon of gas, which translates to around 24 megajoules of electricity per gallon at 20% efficiency. So, that's around 46.7 million gallons of gasoline. Gas is around $2 a gallon in Dubai, so that's around $93.5 million. That's not very much compared to the initial construction costs of such a structure.
That's just the initial cooling, of course, there's still the matter of keeping it cool afterwards. With such a large structure, heat transfer from the outside is almost negligible with proper design. It's a huge number compared to a regular home, but it's very small relative the the massive volume. Then there's the heat generated inside. A typical human puts out around 100 watts of heat just by being alive, then there's all the lighting, cooking, and every other use of power. Guessing a kilowatt of heat generated per person wouldn't be too far off. From the numbers I've found, I'm estimating that they're expecting an upper limit of about 4 million people continuously (180 million visitors per year, guessing they will stay for a week, plus some permanent residents), so that's 4 gigawatts of cooling, or 126 petajoules per year. Going by our previous figures, that's around $10.5 billion dollars per year. That seems like a huge sum of money, but that's only $58 per visitor if they have 180 million per year (and it obviously scales down somewhat if they have fewer visitors).
These numbers are all rough, of course, and use naive assumptions about the shape of the dome, energy consumption, design efficiency, source of power etc. Obviously powering by gasoline would be crazy from an ecological standpoint, but there's an abundance of solar power available there, and the gasoline cost is just a stand-in. The numbers I gave are skewed towards the worst-case scenario, and they're still reasonable. There's nothing impossible going on there. There may be plenty that can go wrong with such a project, but making out the air conditioning in to a near-apocalyptic problem is a bit hyperbolic.

It all depends on exactly which definition of "dinosaur" you use. Many, if not most, modern palaeontologists consider birds to be dinosaurs. Even if you use the traditional definition of dinosaur that restricts them to the Mesozoic, there were birds during the Jurassic and Cretaceous, so you would be saying that birds who didn't survive the era were dinosaurs, but those that did aren't. Which would make it weird for any bird species that survived unchanged well past the extinction. Would that single species be a dinosaur species up to the end of the Mesozoic, but cease to be right at the boundary? Would they just retroactively not be dinosaurs?

That's not really just an idea from xkcd. Modern taxonomists group birds within the clade Dinosauria. Also, birds have tails, even if they're short. The tomia of a number of birds are also very toothlike. A number of dinosaurs, such as T. Rex had all kinds of adaptations to make their skulls lighter relative to their bodies.

So chess is not a sport, but speed chess is?

Deemed by me?

I went back and read the (score:-1 Troll) post again. It still says:

Sorry still sounds like it's deriding the "fodder" (I'm going to assume that he doesn't actually mean for them to be eaten) and glorifying the cowards hiding behind them.

You really seem to attributing to me a lot of things I didn't actually say. I makes it hard to even understand what you're talking about.
