Gravitational Waves: Ripples In Space-Time - NASA Goddard - astrophysics

Notes by NASA Goddard:Gravitational waves are ripples in the fabric of spacetime.They are caused by some of the most violent and energetic events in the universe,including colliding black holes;merging neutron stars or white dwarf stars;the wobble of neutron stars that are not perfect spheres;and possibly even the remnants of gravitational radiation create by the birth of the universe.*Gravitational waves were predicted by Einstein's General Theory of Relativity,but weren't confirmed until 2017.The NASA/ESA Hubble Space Telescope was able to photograph the galactic source of the waves.This opens up a new era of multi-messenger astronomy.

Scientists discover cause of brightest-ever burst of light | BBC News - YouTube - cosmology

According to US scientists,it was caused by a small star supernova 2.4 billion light years away,with gamma ray emissions 100 times brighter than anything ever seen before.The blast lasted seven minutes.It doesn't make sense based on our current model.It's estimated that such an event occurs only once every 10,000 years. Cosmology is the study of the origin and structures of the universe.What would Einstein have thought about this strange event?If there's a black hole involved,the answer could be there.
