Great, now you have to pay them to abuse it. Also, that sucks, I just started playing with it.

The same thing we see, only slightly clearer than on a clear night.

He said while commenting on a social media website.

It does, but very slowly. The Earth is very massive and that thin layer of water on the outside, while it may seem impossibly deep to us, is something like 0.00025% of the mass of the Earth. It's like trying to brake a freight train by dragging a toothpick on the ground.

At 1 atmosphere of pressure water will boil at 100C and the boiling point goes up as pressure goes up. If you keep heating water in a confined space it won't boil as long as it remains contained. It would start making steam but the steam would make the pressure go up. As long as the container holds it will just get hotter and hotter, well in excess of 100C.

This is what happens in a pressure cooker. The pressure builds to about 2 atmosphere and the temperature of the water can climb above 100C, cooking your food faster. A pressure cooker is a very weak vessel, though, it doesn't take much to blow the lid off (don't do that). If you had a vessel with thick steel walls, like the boiler in a steam train, you can go much higher.

Absolutely not. We have billions of years of genetic heritage on this planet. If we were Martians then we would, at the very least, not fit into the genetic landscape on Earth, if not have a completely different biology.

If it stopped all at once then the entire planet would be destroyed (probably). That is a lot of inertia. But the bits of you that still existed for a brief period would be very warm, indeed.

If the Earth completely stopped rotating without any of the inertial consequences, it would have a day of about 1 year. There would be a ~6 month period of burning heat, and a ~6 month period of complete darkness and cold. The heat would be like nothing else experienced on the Earth that we know, a hot summer day that lasts 6 months with no respite. If it doesn't cook us then the droughts and wildfires will finish us off. It'll be too hot and dry to grow any of our crops. The cold side will be frozen solid and in darkness for 6 months, also little chance of survival.

If the Earth becomes tidally locked, which means the same side always faces the sun, there is hope. There will be a ring of twilight where temperatures may remain survivable, but the hot side and cold side will be even less survivable. However, the weather as air of vastly different temperature is exchanged between hot and cold sides would probably make it unlivable even if the temperature in the twilight zone is livable.

Raptor Lake is faster than M2 in the benchmarks I've seen. Apple still has the edge in power consumption by a large margin, but that's less of an issue for professionals.

There are a few problems with that. The first thing being throwing something toward the Earth won't mean it impacts Earth. This is not how orbits work. In order to get from the moon to the Earth, you have to throw it in the opposite direction from the moon's velocity.

But ultimately that velocity is going to be very high. The moon orbits the Earth at about 3,600km/h and you'd have to throw that hammer at a good percentage of that velocity in order to lower the hammer's lowest point in its orbit so that it would hit the Earth. This is just something orders of magnitude beyond what a human being can do.

Edit: If you could do what you're suggesting then we'd already be mining the moon. The biggest problem with mining something like the moon is getting fuel to return the material to Earth. If all it took were a human-scale toss to return to Earth then we'd be hurling minerals our way like there's no tomorrow.

What is "Earth-based math?" I'm genuinely curious why you'd think math would be specific to Earth. If you were to imagine an Martian civilization completely separate from Earth, completely different species, who also develop mathematics, they're going to have the same concepts of the numbers, basic operations, etc. Math is less of an invention and more of a discovery.

Nothing acts as one large mass, not even the Earth or the moon individually. In Newtonian physics they're seen as masses at single points because at a certain distance that's close enough to what they act like and it makes the math easy, but nothing in reality actually acts like that. If you tied the Earth and moon together then nothing would change, they would act like they do now.

And what would these people do? Floating weightless on a space station your entire life with absolutely nothing to do is not an existence we should be engineering. You'd also be suspending a quadrillion people in a completely dependent situation, constantly one supply ship away from disaster and saddling the rest of humanity with supplying them. Half the point of colonizing Mars is to create another space habitable by humans, not merely a habitation.

And if all you want is mass, we have many asteroids not stuck at the bottom of a huge gravity well to mine.

In our solar system, yes. We can practically do it with current technology.

Extrasolar planets, no. Not with current technology, not with any foreseeable technology. The distances are so vast that it would take tens of thousand of years to reach the nearest star. It would be possible, I guess, to build a generational ship and reach them, but then "we" are not reaching other planets, our descendants are and I think that's fundamentally a different question.

You cannot arrive before the light of the explosion, you would have had to travel faster than the speed of light. If you travelled at the speed of light, you would have arrived at the same time the light from the explosion reached here.

No. If we were transported here instantaneously, then we wouldn't be able to see ourselves arrive because we've already arrived. Imagine running 100m, you can't turn around and watch yourself arrive. Even if you run the speed of light you can't turn around and watch yourself arrive.

It would take much more energy to rendezvous with a rogue planet, and when you're talking about a generational ship (which would presumably be massive), that's a lot of energy. It would take far less energy to just go to your destination, and I'm pretty sure energy would be the most important factor on a trip like that.

Eventually, probably, but not within any foreseeable future. Transhumanism might be involved, so "mankind" might be a bit of a gray area.
