No, dark energy and black hole gravity are two separate phenomena that do not directly interact with each other. Dark energy is a theoretical form of energy that is thought to be causing the accelerated expansion of the universe, while a black hole's gravity is a result of its mass and curvature of spacetime.
A black hole is more dangerous than a dark hole. Black holes are regions in space with gravitational forces so strong that not even light can escape, while a dark hole does not have a specific scientific definition and may refer to areas of space with lower light or energy levels.
What exists at the center of a black hole. Why is dark matter unaffected by photons. What is dark energy. Examples...
No. And the term is "black hole," not "dark hole."
I believe the closest black hole is in the center of the Milky Way galaxy... But is a black hole a dark hole? Hmm.
No. The only thing "in" a black hole is pure gravitational energy.
Particles falling into a black hole release a large amount of x-rays as they do so. This is not energy from the black hole itself, but energy release that is a sign of a black hole.
No, since the only theory that has been created to solve the "black holes must have entropy" problem is Hawking Radiation, which was thought up by Stephen Hawking himself. It states that before any particle hits the event horizon of a black hole, it splits up into a particle-antiparticle pair. Whichever particle contains negative energy is sucked into the singularity, while the particle with positive energy escapes. Thus to an observer it would appear as if the black hole was emitting minute amounts of mass and energy.
No, dark matter is quite a different kind of thing. A dark hole may have absorbed some dark matter, but pressumably that would become indistinguishable from the normal matter, once it gets crushed by the enormous gravity of the black hole.
The sun's energy has not formed a black hole.
A black hole sucks all the mass and energy which passes it, even light. So it's called black hole.
