Gravitational Waves

Post by SebastianG » Thu Feb 11, 2016 5:46 pm

It seems like they measured gravitational waves for the first time!

I wonder in what kind of medium the gravitational wave propagates? ;)

It seems bullshit gravitation waves.
Exactly 100 years after postulating they now say to have proven it.
What two energies should there oscillate?

The gravitational wave thing is interesting.

Mostly because it is essentially a rerun of the Michelson-Morey experiment. They didn't measure a gravitational wave directly per se (it could be one), but they instead measured a variance in the velocity of the aether with respect to the earth.

The assumption here is that the chirp was caused by two rotating black holes, but of course those black holes were never seen. There was a gamma ray burst at the same time. If the gamma ray burst and what they measured were caused by the same thing, then that tells me they don't know anything about gravity waves or gamma rays, since they also know that merging black holes cannot emit gamma rays.

Honestly all this ruckus seems too great for a hypothesis that's so tenuously confirmed. With the inability to disprove that what they measured was caused by merging black holes, this all seems a bit pseudoscientific to me.

The irony is that gravitational waves themselves require a medium of propagation, and in order to measure variance in that medium, we must measure variance using "mediumless" light waves. This seems way too disconnected and it breaks the whole point of rejecting the aether due to occam's razor, since we've inevitably had to come up with another medium regardless.

It would be interesting to have a virtual meeting/discussion. Does everyone have a Skype address? I would love to discus and exchange ideas verbally. My Skype address is rcerny. We could easily have a way 4 meeting/discussion.

A group of Danish researchers just submitted a paper arguing that the celebration might have been premature.

I also found some interesting sounds / animations of the measured and theoretical waves:

I'm looking forward to see the first measurements of the LISA project, hopefully their noise in the signal is lower:
