Active galaxies are thought to be powered by?
Active Galaxies are thought to be powered by rotation
Is the speed of light effected by black holes?
Nope.. Light always travels at the same speed. However, black holes do affect the trajectory of the photons, hense diverting the direction of the light.
What causes the speed of light to vary?
Obstructions, black holes, etc.
Why do stars of galaxy's only orbit black holes in 2 dimensions and never totally in gulf the black hole?
because the black holes that they think are at the center of galaxies most likely have rotation, and the stars around it orbit the black hole somewhat like an accretion disc.
How fast do back holes move?
Everything is moving away from everything else at the same speed, so black holes moving is relative to where you are.
Can light escape black holes?
No. The escape velocity of a black hole is greater than the speed of light.
How long is a day on a black hole?
I don't think you could talk about a "day" on a black hole - for a start, nobody could survive in a black hole, to observe such a day. But if you refer to the rotation, one black hole has been observed that seems to spin over a thousand times per second. This rotation, of course, can be different for other black holes.
Why black hole has much gravity and what is it's source?
The source of its gravity is its mass. Black holes also have the property of being very dense. Black holes by definition are objects where the escape velocity is equal to or greater than the speed of light.
Is there anything black holes can't suck up?
There are hypotheses about so called 'virtual particles' that may travel faster than speed of light, and hence are not sucked up by Black Holes. Also, Black Holes cannot suck another bigger Black Hole, when they meet a bigger one, they get sucked up rather.
Why do black holes rotate?
It's quite probable that all black holes spin. The probability of a huge amount of matter collecting with no net angular momentum is vanishingly small.The first solution of general relativity's equations for a black hole was found by simplifying the problem to assume that there was no rotation. Thus, it is possible to find, in the literature, papers referring to non-rotating black holes. Later, a solution was found that allowed for rotation, and this is the most realistic physical situation.
What were black holes before they turned into black holes?
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
Could the theory of dormant black holes truly exist if a black hole isn't sucking in matter that it musnt be rotating if it isn't rotating how could it even exist?
The rotation is not related to the black hole's ability to attract matter. The attraction depends only on the black hole's mass.The rotation is not related to the black hole's ability to attract matter.
