Now, you could load up like double your fuel and slow down and have a rocket shooting in reverse.

But that would be an incredible waste of fuel.

So they use the air to slow down.

The problem is as the air hits the thing, it heats up the ship to like, what, 3000 degrees Celsius, which is balmy by anyone.

Am I going to shock you right now when I throw some letters at you?

PV equals NRT.

I remember that from school for anyone who was totally cross-eyed as I say that.

As you change various properties of gas, certain things change.

And the T is temperature.

So if you compress it, and the P is pressure, and it's on the other side of the equation.

Am I getting this right?

So if you dramatically increase the pressure quickly, the temperature goes up super high.

It's like the noble gas law.

Yeah, it's ideal to be noble.

You know, I'm imagining myself in the Renaissance era in England.

You know, if you're a noble person, that's pretty ideal.
