I was watching a program on Black Holes either on the Science Channel or Discovery. The latest theory is that every Galaxy has a Black Hole at it's center, and this includes our Galaxy the Milky Way. Some Black Holes are more active than others. Sucking in stars and planets while others like ours are not and only suck in some space gases now and then.
This made me think and question. Are Black Holes the glue for each Galaxy? Are they what keep all the stars of each Galaxy from just going any direction they so choose. I mean the latest space images from the Hubble showed us that most of the stars we see in the sky are in fact, spiraling Galaxies. And it just stands to reason that they must be spiraling around something, and that something is a Black Hole.
They also theorize that a Black Hole may have created each Galaxy and could also be the end of a Galaxy. After sucking in everything around it, it just creates another new Galaxy. Kind of like space urban renewal.
And when two Galaxies come together and their Black Holes combine it is very violent and possibly means the death of everything in both. This could be the fate of our own Galaxy as our closest neighbor the Andromeda Galaxy is moving toward our Milky Way at a high rate of speed. Not to be alarming but we are still looking at a BILLION years from now. But at that time computer models show that the collision of the two mean that everything on Earth would evaporate and the Earth would become a barren wasteland with no life what-so-ever.
Sombrero Galaxy
Something very energetic is going on in the center of the famous Sombrero galaxy, where a great deal of X-ray light has been detected. This X-ray emission, coupled with records of unusually high central stellar velocities in the galaxy, cause many astronomers to speculate that a black hole lies at the galaxy's center.
Black Hole Dust
A Hubble Space Telescope image shows a spiral-shaped disk of dust fueling a massive black hole in the center of galaxy NGC 4261. Astronomers calculate that the object at the center of the disk is 1.2 billion times the mass of our sun, yet it is concentrated into a space not much larger than our solar system.
They is there light if it is a black hole then? I can see light directly at the center of the universe, if that is true, wouldn't that mean that the light would be sucked in to the black hole, hence the name?
Well, I'd think that it's possible for the gravity to pull light towards the rim of the Black Hole, causing it to accelerate, and if the light comes toward the hole at a sharp enough angle, I could see that it would just be whipped around the rim of the hole, and fired out at an accelerated velocity. If lightspeed is moderated by some force, then after it got out a certain distance from the hole, it would slow down to normal lightspeed again, and would be visible to us.
I don't know if my idea has any merit, but it doesn't seem to be outside the realm of reason....
The problem with balck holes is that it doesnt even let light escape, the only wat to know if a black hole is there is to see the effect it has on another object, its like wind ... you dont know its there unless you see the trees brances moving...
So you will only see a black hole when it is near a star.
