is it possible, or has it been observed, one black hole eating another?

Answer 1

It hasn't been observed directly, but there are x-ray, gamma ray, and infrared observations of galaxies that seem to be merging, and evidence that there are black holes at the centre of each that are in the process of merging.
The theory of black holes does not say it can't happen, and in physics whatever is not forbidden by the laws of physics must happen at some time (even if we haven't seen it directly).
In addition, the supermassive black holes at the centres of some active galaxies are hypothesized to have formed due to the coalescence (merging) of 2 or more solar-mass black holes at some time in the past.
So yes, its possible, but no it hasn't been observed directly.

Answer 2

No. All the black holes we know of are too far away to be observed doing anything. There have been gamma ray bursts that scientist theorize are caused by the collision of neutron stars or black holes though in the case of black holes it would actually be the collision of the accretion disks around them, not the holes themselves since no radiation could escape the actual collision and merging.

Answer 3

The answer is yes.
Although the same has not been observed yet. Recently NASA solved a 35 old mystery of a black hole eating a neutron star, so that has been observed.

Answer 4

A majority of astronomers believe that black holes wouldn't "eat" one another but instead would merge into a more massive single black hole. See this website for more information along with graphics of such an event ==>http://www.science.psu.edu/alert/Sigurdsson5-2005.htm

Answer 5

NO! Black holes don't "eat" one another, theoretically if two black holes collide, they'll just merge. And no it has not been observed.

Answer 6

Black hollow isn't hollow in a stable be counted like earth. It exist interior the universe, the place it is given this call because of the fact it cant be seen via telescope or via the different form of telescopes. No radiation comes out of it. it is made via great stars compacted so strongly that the gravity is so extreme that even easy debris can no longer come out and as a result invisible. via extreme gravity it could eat different small and huge stars around it. it is an consumer-friendly answer on your question. they are irreversible different than whilst they blow themselves out

Answer 7

Yes Supermassive blackholes will devour everything.

Answer 8

if black holes collide they merge.
