The authors raise a key point about the detection of gravitational waves from the early universe. Not only would such a detection verify the theory of inflation, but it would also prove the quantization of gravity.
Short gamma-ray bursts, extremely energetic explosions in the Universe, might be caused by the merger of two compact objects. In the two papers we discuss today, the authors test this scenario by looking for light emitted still a few days after the explosion.
The race to be the first to detect gravitational waves is on – are pulsar timing arrays on the verge of a discovery? New predictions based on revised galaxy merger calculations suggest that it may be so.
