If blackholes are in the center of most galaxies and galaxies are orbiting each other and galaxies are moving away from the big bang then can you say that blackholes are moving? But if blackholes are moving that would blow apart Einsteins theories. As a Black hole would require infinite energy to cause it to move.
Or are black holes stuck in space at absolute zero velocity and are giving the impression of movement by constantly sucking in the fabric of space/time like a vacuum sucking up thread from a carpet. All the blackholes are sucking in this stretchable space and as a result space between the planets are becoming larger.
A easy example. Stretch out a *huge* piece of saran wrap. On the saran wrap draw independant galaxies in scale and in the center of these galaxies put a weight that hangs through it which caused the saran wrap to stretch. As the saran wrap stretches in multiple places at the same time with various weights you'll see space expanding before your eyes.

How can a blackhole move? The blackhole to move would require infinite force. Can it be said that a blackhole holds as much energy as a spaceship moving at the speed of light?
If you can increase mass of the ship while it is going the speed of light while maintaining the speed of light then that would be equal to exceeding the speed of light.

My bad. Got infinite density and infinite mass mixed up.
How much mass is just short of infinite? Say the mass of an object going .95 the speed of light.

Not even a good analogy. Paragraph three could use the delete key.
Back holes move. How they work is very simple. Too bad I have not the time to explain it to you.

Most galaxies have more mass than the "average" black hole.
They move, don't they?
Most, if not all, galaxies have a black hole at their center!
And there are many others moving through that galaxy too.
It's thought that black holes begin as collapsed stars. Gas clouds or stars that come too close are pulled apart and swirl down into the black hole.
Your saran wrap is a great way to picture the universe of galaxies moving across space in a curve.

Black holes move just like any other stellar object of comparable mass. Black holes have finite mass. It doesn't take any more energy to move a 10 solar mass black hole than it does to move a 10 solar mass star. The energy to move a black hole certainly isn't infinite. Perhaps you are confusing mass with gravitational potential energy? The two are related, and in General Relativity they can, to some extent, convert into each other, but they are not the same thing.

A black hole is not infinite in mass nor moving very very close to the speed of light in all cases. There's no reason to suppose it as infinite mass. Black holes can me as low in mass as 20 or 30 suns.

A black hole can move like anything else. A black hole can orbit a star for example. In fact, the black hole's extremely high gravity field would allow it to be pulled around by other high mass objects.

Who told you a black hole would take infinite energy to move?
I'm not entirely sure you've understood general relativity. Many small black holes of a few solar masses orbit stars in this galaxy. You can't be 'stuck in space' - there's no reference point so you can't find anything that is stable relative to anything else. it wouldnt mean anything.

no i think not because i think scientists sometime landmark certain spots in universe by presence of a blackhole......
