WebNov 13, 2024 · Listening for Gravitational Waves Using Pulsars. This computer simulation shows the collision of two black holes, which produces gravitational waves. One of the most spectacular achievements in physics so far this century has been the observation of gravitational waves, ripples in space-time that result from masses accelerating in space. Webgravity at the end of the horizontal flight. A related proposal [6] would involve measuring the gravitational deflection of slow positronium atoms (bound e + -e-pairs) in high n states in which their annihilation lifetime would be very long. The advantage of using electrically neutral atoms for a test would be a reduced sensitivity to stray fields.
