Five Star Question Of The Day:

What can a greater understanding about merging black holes tell us about the nature of time?
 
Physics news on Phys.org
I think that the question may be circular, because we will probably require a greater understanding of the nature of time, in order to understand the merging of black holes better.
 
LISA's detection of gravitational waves will allow us to see the merging of black holes in great detail.
 
Something to look forward to :)
 
"The nature of time" is rather philosophical. But the gravity wave detection of "merging black holes" (or other binary inspirals) will tell us a lot about whether General Relativity is correct or not.
 
I asked a question here, probably over 15 years ago on entanglement and I appreciated the thoughtful answers I received back then. The intervening years haven't made me any more knowledgeable in physics, so forgive my naïveté ! If a have a piece of paper in an area of high gravity, lets say near a black hole, and I draw a triangle on this paper and 'measure' the angles of the triangle, will they add to 180 degrees? How about if I'm looking at this paper outside of the (reasonable)...
Thread 'Relativity of simultaneity in actuality'
I’m attaching two figures from the book, Basic concepts in relativity and QT, by Resnick and Halliday. They are describing the relativity of simultaneity from a theoretical pov, which I understand. Basically, the lightning strikes at AA’ and BB’ can be deemed simultaneous either in frame S, in which case they will not be simultaneous in frame S’, and vice versa. Only in one of the frames are the two events simultaneous, but not in both, and this claim of simultaneity can be done by either of...
