Light and gravity travel at the same speed, but don't arrive together

Gravitational waves and light travel at identical speeds; the observed two-second arrival difference arises from emission-timing and source-process differences, not faster propagation.

Ask Ethan: Can Weber bars detect gravitational waves?

Weber-style bar detectors are critically limited by their small size compared with modern interferometers, making them unlikely to achieve sensitivity required to detect gravitational waves.

Scientists Detect Strange Signal in Gravitational Waves

For the first time, astrophysicists have measured the recoil - or " kick," in the parlance - resulting from the birth of a new black hole that formed from the merger of two preexisting ones. The international team of researchers measured the ripples in the fabric of spacetime, known as gravitational waves, allowing them to get unprecedented insights into the turbulent dynamics of two black holes crashing into each other.
