I have read that they emit radio waves. Does anybody know what band I tune into to hear them? AM or FM? Shortwave?
And I read that they emit x-rays. Does this mean that astronauts ought to be wearing lead-shielded space suits?
I have seen where they emit Space Confederation, Borg and Klingon ships.
I am pretty sure that's what's causing all the trouble in the Bermuda Triangle, too. The aliens really object (on the grounds of copyright infringement) when humans wear Bermuda shorts or eat Bermuda onions, and they zap them through to the other side of a nearby black hole.
Black holes are responsible for a lot of problems that science has yet to solve. Things like...where does the missing sock go when you're doing laundry? How do those wire coat hangers you get from the dry cleaners tangle themselves together in the closet when nobody's watching? It's black holes doing it.
Black holes release x rays. That is what how proof ox existence was determined! Hawking predicted both that black holes existed and that they would emit x-rays. He was right, and he won the bet with his colleague!
Inflowing matter that hasn't yet passed this point of no return can — through friction and interaction with the black hole's strong magnetic field — release energy in the form of either diffuse light or focused jets of energy.
Most of the energy in the jets is being emitted as radio waves, but in at least one of the 9 black holes studied, the energy was in the form of more energetic X-rays.
As the matter falls or is pulled towards the black hole, it gains kinetic energy, heats up and is squeezed by tidal forces. The heating ionizes the atoms, and when the atoms reach a few million degrees Kelvin, they emit X-rays.
