We do physics in a space of some number of dimensions. We think space exists and, as confirmed by our eyes and hands, is a big place that needs coordinates to specify its many locations. Your question is based on that assumption. Then maybe there is some smallest pixel in this space. Instead of specifying n=4 coordinate values for the pixel, perhaps we ...

Striking a 1 gm meteoroid at 10 % c with a structure like ISS, would not even slow the 1 gm meteoroid down much. It would make a small hole in, go through and a small hole out. The affected areas would vent atmopshere and need to be sealed, but the structure would survive. Going from 10 % to 9.98 % of light speed. IF the craft was heavily armored with 4 ...

Well, the temperature profile of an object on the macroscopic scale is governed by, $${{dT} \over {dt}}=\kappa \cdot \nabla^2 T $$ Where T is the temperature, t is time, and $\kappa$ is the thermal diffusivity. It's the constant that matters here. The larger the constant, the faster the temperature changes. The equation itself is called the Heat Equation. ...

You can't tell directly. But you can look at a bunch of it and notice that it is at the same temperature here there and everywhere in all directions in every single place where your view isn't blocked by some moon planet star or galaxy. And that temperature is quite cold it is hard to get something that cold. And either there are many things with the same ...

Distance is equivalent to time. The time at which the cosmic microwave background was emittied was the time when the universe made a phase transition from being a plasma to being atomic matter. During this time, the universe finally became transparent. Before this time, the universe was so hot that all matter was opaque. The CMB is the wall that ...

Yes space is a vacuum which means no pressure and air and no gravity. As you said ice melts quickly in high pressure so in space ice will take a longer time to melt if it's not so hot there.
