Super massive black hole at the center of our galaxy

the idea of black holes is flawed at a very low level. Black holes are entirely a concept, and there are no known black holes. Furthermore, as someone has already pointed out, if an object, such as the sun, or a group of objects, such as our solar system, were turned into a black hole,it would simply centralize all masses in our solar system to one single, infinitely small mass. This would have the same effect on other solarsystems as our current solar system, and no other planetary bodies would feel a difference. The idea of an infinitely dense "black hole system" that continually sucks in planets and stars is illogical. Since gravity depends on mass, gravity cannot be created, yet it must spawn from some sort of mass, which already has a gravitiational impact. Simply packing together this mass into a tiny ball and calling it a black hole will not create a stronger gravitational pull than the individual parts of mass that created it. Gravity is a 1+1=2 concept, and ideals of the "whole" being greater than the sum of it's parts do not work.

Is that so...? :laugh:
Center of the Milky Way

Sorry alienal99, I'm not trying to make fun of you, I just thought what you said....ok, I'm making fun of you. 😉

this i found at science daily yesterday, interesting. a pic of where the chandra x-ray observatory found evidence for a "Swarm" of black holes near the galactic center

Here's another pic of a blackhole: pic

You would think for how ever many billions the teloscope cost they could get a picture with a little more details of the center of our galaxy.

I thought there was a planet in the center of the galaxy with a guy named 0 who the crew of the Enterprise fought in... star trek VI?

They have proved the existence of black holes. Actually, objects accelerating towards them giving off radiation was our beacon. Now they are trying to use hawking radiation to see if we can recreate, at least on paper, what the black hole ate.

Yeah and just....what, twenty five years ago? black holes were still almost science fiction or myth.

Yea, dont the black holes kind of defract light a little bit too?

I'm not sure but I believe so. Besides the fact that there's no light coming directly from the black hole, I think it would somewhat bend or warp any light that was close enough to the event horizon. I could be wrong though...😕 I know it's not how they detect them anyway, or not the only way. Anything with mass will defract light somewhat; I'm guessing that the enormous mass and gravity from a black hole would make it somewhat more apparent.

Black holes are detected from the high energy electromagnetic radiation emitted by matter from their accretion disks as it gets pulled towards the event horizon. The galactic center is far more densely populated with stars and gas than our region of space, so there's always plenty of matter to form an accretion disk.

A black hole in intergalactic space would be invisible, as there is too little matter there to generate enough radiation to see it. However, it could be indirectly perceived through gravitational lensing. Since gravity bends light, it's possible to get a double image of a distant star or galaxy due to a large object such as a black hole located on your line of sight.
