Kindly permit me to ask why we should assume that these galaxies are running away from one another because of big bang explosion/inflation, === could they not be ATTRACTED by some other gravitational forces located in the infinite universe? In any case, it seems to be accepted that for some peculiar reason the explosion/inflation has pushed away its constituent matter in all directions (not only in a spiral disk}. In an infinite universe, there can be no centre, west, east etc.

Kindly do send me this information regularly. I request, in particular, some information about SPACE in relation to the Big Bang theory -the illogical and skin-saving "singularity " of the big bang or the big inflation did require matter with mass although infinitely compressed, infinitely hot etc. Now, when this thing exploded or inflated, was there already space in existence or the expanding matter created automatically the space required for inflated matter AS WELL AS ALL THAT EXTRA LEG ROOM REQUIRED FOR CONTINUOUS FURTHER EXPANSION AND SPACE BETWEEN GALAXIES ETC. ETC? I am curious to read some brilliantly thought out explanations with countless singularities (if required) for SPACE. I believe that SPACE is not matter, nor energy, gravity etc. Also, How does gravitation force first compress the big-bang matter infinitely and then let go in a bang to such as an extent that the resultant matter/mass is constantly expanding and distancing itself from other such groups/galaxies etc.? Kindly help. Thank you.

G'day from the land of ozzzzzzzzz

The process of black holes been kicked out is questionable. The normal process is that stellar black holes form within the envelope of the galaxy and in time move towards the centre. During this process it will merge with other stars and black holes growing larger and larger until there is one huge one formed. Supermassive BH can eject matter in huge amounts and large stellar black holes can form in these supermasssive jets and it would seem they have been kicked out. It may be possible for stellar black holes to be caught in the jet stream.
Compact matter can form very quickly as a result of a supernovae, eg Neutron star with 10^17 Kg/m3. Ejected matter via jets may do the same.

All these can be explained without massive
black holes or dark matter.

This mean that there could be million solar mass black holes flying through the universe. I've read about large star black holes being flung out of a galaxy but never the central core black hole. One more thing to worry about.

So when the Adromeda galaxy collieds with our galaxy, our blackhole gets kicked out? Or Adromeda's?

Ohh yeah? I bet my galaxies black hole could beat up your galaxies black hole!

The Andromeda Galaxy has TWO black holes at its center, which means that at some time in the distant past, it had a collision with another galaxy and essentially "won".

By the way, that "artwork" of a black hole flying out of a galaxy is terrible. It looks like some amateur quickly slapped something together. Whoever put that out should be embarassed – plus he or she took away a job from a real space artist who could no doubt do a much better job.

thats not a black hole being kicked out of the galaxy, it looks more like monkey magic on his fluffy cloud of wrath

Looking at the background galaxies in this picture, it looks
like there is some interesting lensing going on here. For
instance take a look at the lower right-hand corner of the
image.

Is this model an explanation why we can't find a central black hole in M33, the LMC or SMC? Curious.

Assuming that one actually did get kicked out and they didn't just settle into a nice little orbit around each other and eventually merge, I'd say that that which one got boosted out would depend on the relative masses of each BH, their spins and the particular way in which they encounter each other.

Jeez, this research group is hogging more than their fair share of the impressive discoveries for the moment, aren't they?!

It that the actual picture? Floating on a cloud zipping away from galaxy only a few times bigger than itself?

This must mean black hole = angels.

Wow, Ian, you posted this story within just a few minutes of mine! I'll be sure to link to yours. You've got some stuff written up that I don't, but I've got some good stuff too. Incidentally, it isn't the star orbital velocities that allow them to calculate its relative speed; this thing is 10 billion light years away, so they can't resolve individual stars. But it's still an amazing event nonetheless!
