Beat the extremes of nature

Factual Questions
1

I was once told that low-temperature is the only physical extreme in which human technology can beat any natural process. I can’t think of any other examples. Can you?

2

Are we restricting to current natural processes, or does, say, the Big Bang count?

3

What about water pressure? If we can build a vessel that can travel, briefly, to the bottom of the Marianas Trench, does that mean we can replicate that amount of water pressure?

4

With the universe being so big, it’s hard to prove this sort of thing. However, I would like to offer two candidates:

  1. electrical conductivity (especially if multiplied by current)

  2. nuclear fission rate and efficiency

I can’t think of that many natural examples that exceed human endeavors in those extremes

5

I was thinking: any known process occurring somewhere in the present universe. So supernovas and neutron stars count; the Big Bang does not.
