There are quite a few photographs from telescopic observations which provide evidence of the existence of black holes. The problem is that evidence is indirect, a black hole can't be directly observed since its gravity is so strong that light can't escape. Hence, photographic evidence lends support to physical theory about how it affects the matter and space around the black hole; for example, the presence and behavior of infalling matter, close orbits of massive bodies, the tearing apart of nearby companion stars, illumination from relativistic polar jets and highly energetic accretion disks, gravitational lensing, all are visible in photographs.
What else can I help you with?
Are black hole common?
A black hole? well scientist are not sure. Black holes is a theory, not proving to be true. But there could be.
How did Karl schwarzschild discover cosmic black holes?
He did not discover them. He did some calculations that predicted the possibility of the existence of black holes.
Do black holes orbit the universe?
Most likely not. The best evidence of the existence of black holes has been found deep within galaxies.
What have black holes got to do with the beginning of the universe?
The density of matter just after the big bang is calculated to be sufficient to have spontaneously created black holes; such are called primordial black holes, and searches for their existence are ongoing.
What forces black holes?
The existence of black holes is an outgrowth or prediction of General Relativity, which was Einstein's theory of gravitation. The dominant force forming black holes is the force of gravity, a universal attraction between mass.
Is the black hole a wormhole?
Probably not. The existence of black holes can be considered to be confirmed; the existence of wormholes is highly speculative, that is, they probably don't exist at all. According to String Theory, worm hole does exist. However black holes are not warm holes. Even if you did found a wormhole, it probably going to be only about 1 atom small.
Are black holes in space?
Yes, that's where they are. A black hole on Earth would utterly destroy the Earth, in a very short time.The existence of black holes is now generally accepted, by the way.
Why was it so hard to prove that black holes exist?
no dude, the evidences of the existence of black holes is now widely accepted and i believe that black holes rules our universe but it is difficult to find them because black holes are nearly the perfectly black bodies
How does a black holes acquire greatest mass?
Most black holes are stellar mass black holes with masses comparable to those of large stars as they form from the collapse of massive stars. Scientists know of the existence of supermassive black holes that are millions to billions of times the mass of our sun and can be found in the centers of most galaxies. Scientists still do not know how these black holes become so massive.
Which of these is one likely to encounter in deep space black truffle black algae black hole black coffee?
The effect of the existence of black holes is supported by observational evidence. There have as yet been no observations that would support the existence of the other items on this list.
What physical theory first predicted the existence of black holes?
The general theory of relativity, proposed by Einstein in 1916, embodied the notion of gravitation, a phenomenon derived from a local curvature of spacetime. One profound implication, an outgrowth of the field equations of the theory, was the existence of black holes.
Do white holes suck up objects like black holes do?
White holes are theoretical regions of spacetime that expel matter and energy outward, the opposite of black holes which pull matter in. They do not suck up objects like black holes do. However, there is no observational evidence for the existence of white holes in the universe.
