StarTalk Radio
Gravity’s Cosmic Symphony with Kelly Holley-Bockelmann

But that's only because our constellation is so big.

So we're just detecting changes one part in 10 to the minus 20 because that's how strong the gravitational waves are.

But because the mirrors are separated by such a huge distance, then the differential scale ends up being bigger.

StarTalk Radio
Gravity’s Cosmic Symphony with Kelly Holley-Bockelmann

Right.

The other thing is that many of these massive black holes, when they merge, they're so loud.

StarTalk Radio

And so the kinds of signals that we're going to get are having signal-to-noise ratios of thousands.

StarTalk Radio
Gravity’s Cosmic Symphony with Kelly Holley-Bockelmann

Wow.

StarTalk Radio
Gravity’s Cosmic Symphony with Kelly Holley-Bockelmann

he's not wrong in that these, these are really, really loud signals.

StarTalk Radio

And so you, your, your instrument just has to work and then you'll definitely catch the, you know, the gravitational wave signal, but you have to get up there.

StarTalk Radio
Gravity’s Cosmic Symphony with Kelly Holley-Bockelmann

And it takes a while to, to build the instrument to get up there.

StarTalk Radio
Gravity’s Cosmic Symphony with Kelly Holley-Bockelmann

And I'm trying not to cry right now, y'all.

StarTalk Radio
Gravity’s Cosmic Symphony with Kelly Holley-Bockelmann

Yeah, I'm going to turn serious now because that's actually happening.

You know, the latest president's budget request has zeroed out, Lisa.

StarTalk Radio

And so we are a partnership with ESA and NASA.

StarTalk Radio
Gravity’s Cosmic Symphony with Kelly Holley-Bockelmann

NASA is a junior partner.

And...

StarTalk Radio
Gravity’s Cosmic Symphony with Kelly Holley-Bockelmann

The U.S., if this request goes through, the U.S.

StarTalk Radio

can no longer participate and give our technology to this mission.

StarTalk Radio
Gravity’s Cosmic Symphony with Kelly Holley-Bockelmann

You're totally right.

Sorry, I interrupted you.
