Can we talk Kaluza Klein a little bit and Randall Sundrum, that sort of thing?

Sure, yeah.

Boy, and you're working on Atlas.

So Atlas has been looking for gravitons, right?

Absolutely.

Without success.

Without success, yeah.

And looking, I think RS1 says there's three ways to prove gravitons exist, the particles exist, and we're 0 for 3, right?

Yeah.

the experiment wrong do we need more energy are they even there are they or are they in is ours one fifth dimension are they out there in compactified space maybe as klein would have said yes so we can't see everything right the collider is limited some things are too rare

some things are too massive, right?

We have a certain amount of energy in our collision, so we can make something on nature's menu if it has mass of a certain amount or below it.

To go bigger, to go above that on the menu, you need a bigger collider, more energy.

So we know the gravitons are not anywhere that we could have seen them, which means they're not below a certain mass or we would have seen them and they're not above a certain rarity or we would have made them and seen them.

So we can rule out low mass, very common, very high production gravitons.

We can't rule out gravitons that are really, really rare or gravitons that are really, really massive.

And so if the universe is like five or seven dimensions, there are definitely configurations where there could be gravitons and we couldn't see them because our experiment is limited.

So we can't see everything.

And that's frustrating.

And that's why, you know, I want to build a bigger collider and I want more space telescopes and I want all of this stuff because it's frustrating to be limited in that way.
