I assume that the energy transported by a gravitational wave is dependent on its frequency, just like EM waves. If that is the case, let's imagine a particle traveling at relativistic speeds relative to the lab frame. Let's imagine the interaction of this relativistic particle with a...
In fact, for an accelerated reference frame, there exists the concept of Rindler horizon, which is quite similar to the event or Schwarzschild's horizon of the hypothetical entity which is called black hole.
Check, for example, this excellent...
So we must wait. After the first announcement and all the excitement, I read the paper and I changed mood, it was too good to be true, like a kind of WOW! signal. I hope that new events will confirm the data, they had detected a few candidates but with much lower sigma.
I understand that the LIGO experiment was very lucky to find a very strong signal of a very energetic event (binary black hole merger). Having into account the non-negligible possibility that the signal may be spurious or some problem in the data adquisition, how much time must pass before we...
Thank you very much. Yes, the results seem to put restrictions to alternative theories, but do not go further than previously known from the theoretical data of pulsar orbit decay, if I understand correctly the data.
As the discovery matches templates based on GR, and the regime is of very strong gravitational fields and very high speeds (relativistic speeds), and there is a 90% match between model and measured data, this does rule out linear or quasi linear alternative theories of gravity?
