Sweet fuck, you guys are imbeciles.

[>>5125087] is right. Most of the heat down there comes from nuclear decay.

This of course doesn't mean that the Earth's interior is warming, and it indeed did originally heat due to gravitational friction and compaction, but it has retained this heat much longer than it otherwise would due to nuclear decay.

There was an infamous experiment by Lord Kelvin to determine the age of the Earth scientifically, using principles of thermodynamics. Of course, at the time he had no knowledge of nuclear decay in the Earth's mantle, so he came up with a mere 20-40 million years.

Lolno. It'd be an absurdly-expensive drop in the bucket, which is why noone in their right mind will ever actually pay to bring resources from extraterrestrial sources.

Do you ask questions to answers you already know just to justify your position on religious views?
Are you so deluded OP that you cannot assign common-sense to your question? Nigga i wont even answer the damn question, because you already know the answer.

If you lived on the edge of the Universe, would you be able to observe it?
Well how would you know it is the edge of the universe is you are not able to observe it?
And what is the "other side" like I said if you cant observe it the what is the edge.
