Enough with the one liners.

So Gundams with Fin Funnels piloted by Newtype pilots are possible after all?

But on the more serious side, think about this, there are so many different types of environments and living conditions out there. This can differ from planet to planet, or if its a colony in space, etc. Now, let's say, after 5 generations, how much difference will there be between the ppl living in the different locations, due to adaptation and evolution? Or even say, after 10 or 20 generations?

Heat is a form of energy. Cold is an absence of heat. So yes, its not just that the universe is cold, but its more of everything is cold. The temperature that we're all so used to is the result of heat and light from a particular source, which is the sun.

Don't think of it as being cold in nature. Cold and hot are just terms that we used to describe temperatures above or below what we're comfortable with. Just think of it as the temperature where no energy is present.

yes correct, of which is why 0 kelvin only exists in theory because it is possible only with the total absence of energy. the 0 degree Celsius that we know is at 273.15 kelvin. So that should give you an indication of how much light and heat energy the sun needs to give out to give us the 30 odd degree Celsius that we're used to @ the equator.
