The big Ligo discovery of 2015 of two inspiraling black holes revealed that about 5% of the total mass of the system was radiated away as gravitational waves. Ethan’s article does a nice job explaining that this energy came from potential energy rather than mass escaping from the singularity. My favorite part was his discussion of how varying the mass and spin parameters of a black hole merger could change the percentage of mass/energy loss.
But aren’t black holes invisible…. So how can the human eye possibly look at even a picture of a black hole as black is not a part of the rainbow spectrum
Vaishnavi Pandey They are invisible, but their gravitational influence on nearby material is visible. Also, gravity waves
Black holes are not completely black. ….can you explain this theory
Prachi Shukla the light from a black hole system does not come from the black hole itself. It comes from the hot accretion disk spinning around the black hole, heated to dramatic temperatures by friction
Chris Dolan thanks
Just amazing raw power……… I”m wondering, how did we manage to get a shot such as this one? Aren’t these black holes light years away from us??? Great Shot
Sultan Salahuddin that picture is just a simulation, not a photo. The gravity wave detected in 2015 that the article refers to is from black holes very very far away, millions of light years. We can’t actually see them or their host galaxy
Chris Dolan Thank you very much Chris..I was making sure that I was not mad!
Magnifique! Merci Chris Dolan!
Chris Dolan Beautiful Simulation, I can see the whole thing much better now! thanks again.
Other particals other then photons must not be interacting. It also explains why there were so wild eathquacks prior to the collision of the black holes
