Colder than Antarctica temperatures.

So now comparing Venus to Mars, the temperature difference is...

A factor of 10,000.

Different.

It's huge.

Now you consider a water world.

Water is only liquid from 0 degrees Celsius to 100 degrees Celsius, right?

So you've got, as long as you have liquid water, you are in that temperature range.

You're not going out of it.

And so it's much more stable temperature-wise.

The pressure varies with depth dramatically.

I mean, atmospheric pressure varies with atmospheric height as well.

But because water is so much more dense, it's much more dramatic.

So you can control what pressure you like by controlling the depth and temperature.

And water has such a high heat capacity, the temperature doesn't change that much.

You don't have the temperature fluctuations of water temperature that you do in air temperature.

So it's a much more stable environment.

You're protected from solar radiation.

You're protected from ultraviolet rays.

You're protected from cosmic rays.
