Gravitational Waves Detection

The cluster focuses on discussions about detecting gravitational waves, comparing alternative methods like precise clocks to LIGO's laser interferometry, and speculating on their use for communication or information transmission.

Interesting that they succeeded in detecting gravity waves where LIGO failed?

bawana Mar 27, 2019 View on HN

wow. interesting.so we might be able to detect gravity waves without kilometer long lasers?

Could you detect gravity waves with accurate enough clocks?

Tepix Nov 13, 2021 View on HN

Please prove it by measuring the resulting gravity wave :-p

Thought LIGO can detect these waves? https://www.ligo.caltech.edu/

Do you have a source for this? I thought they were a direct prediction of GR and this link says the same: https://www.ligo.caltech.edu/page/what-are-gw

> seems horriblyNo physicists here but you don't seem to be either. Irc from what had been said with the first event gravitational waves pass through matter and aren't disturbed like em waves, that's why they supposedly open new doors. Secondly, just take it at face value, if they say so it is so, it might seem improbable and "horribly prone to manipulation" but they probably thought of that and have machines precise enough to compensate for whatever effects you or

24 kHz gravitational waves are made by…a pair of objects orbiting 24 thousand times per second.This happens when black holes or neutron stars merge and that's it; this means you don't have enough of them to do what you're claiming, not even if I trusted what looks suspiciously like you blindly asserting without evidence how much they should alter wavelengths.The effect of gravitational waves is barely anything even on the LIGO detector, and they need to use a squee

Would it be possible to listen for information transmitted via gravitational waves? Would there be any benefit over radio?

The article mentions gravity waves, I thought these were not possible to detect except from massive events like black hole mergers. Am I getting concepts mixed up?
