I think it's it's like how we we share knowledge and build on on one another and how the nature of, like you said, of collaborating and really working towards something bigger than than we knew before.

Yes.

No, bits and pieces of it are being built by by different nations and we all put it together.

So, for example, the U.S.

is responsible for the laser, the discharge management system that I talked about and the telescope.

Yes.

Um, which one there are telescopes that, that are actually made out of glass.

It's a very, very, uh, temperature stable glass called zero door and it's translucent.

Um, and so if you kind of, which I think is really cool, there's a picture of it where you can, where there's like a test model right now and they shine a light underneath it.

So it glows really, really well.

You're exactly right.

The whole name of the game for LISA is to keep everything as still as possible.

Extra charges, even air that would be left over in the instrument.

Sometimes there's this outgassing that you do to get rid of all the air in a space instrument, but individual air molecules hitting that test mass will fake a gravitational, it'll make it move.

It'll make that test mass move and make it seem like a gravitational wave.

Wow, it's left over from the... Left over.

Yeah, that's what happened.

Absolutely.

That's that oxygassing stuff that we were just talking about.

In fact, sorry, story time.
