And so the life of the stars is really going slower if I look at the measurements.

Yeah, particularly for the big, massive stars.

Yeah, and they get more material into their inner part.

And in the inner part of the stars is actually a nuclear reactor for me, because they're

The simplest constituent, which is hydrogen, is turned into helium by nuclear fusion.

Stars are masterpieces in that.

But if you bring more hydrogen into that area where it's hot and dense enough, then the star can live longer.

And so the rotation affects how much nuclear fuel you bring inside its interior, actually.

Once the nuclear burning is ongoing, the nuclear fusion in stars is stable.

Stars are...

can do that very well.

We humans can't do that here.

Yeah, well, tiny.

It's 10% of the mass that typically takes part in the nuclear fusion.

So it's still 10%.

It's not that small.

Yeah, because the density is very high.

And so if you change that 10% to, say, 12%, that sounds like, you know, it's only 2%, you know, but that's a lot of fuel.

that you bring into your nuclear reactor.

Yeah, yeah, yeah.
