Recently scientists have found evidence that there exists a super massive black hole in the centre of all galaxies, not only active galaxies but calm ones like ours and andromeda which was previously not believed. All the particles in galaxy (like solar systems, binary systems, stars,) revelve around the centre of a galaxy which can be now explained that this is due to super massive black hole at the galaxy's center. But all the galaxies revolve around the centre of universe. So there must exist the most massive block hole at the centre of the universe. And also if it exists why is universe expanding? wont all the matter be compelled to be sucked in by this black hole and the universe contract? Please answer me if athe most massive black hole exists at centre of universe according to you and your reasons for saying so. Isnt astronomy so interesting?

There is no such thing as the center of universe.
Or, one can put it differently - any point can equally be considered a center of the universe.
Think about it - YOU are a center of a Universe.
Why is it so? Imagine that we only had two dimensions, not three, and leaved on a 2d surface of a sphere. Where is a center of that surface? In our (2d) world it simply does not exist. There are no 'special' points on the surface of the sphere - they are all identical.
If you pick any point on the sphere, and figure out a distance from it to another point, that is the fartherst, you'll always get the same result (pi*R), whichever point you pick - so, you can choose any point to be a "center".
Same with the universe, only our "sphere" is a 3d manifold, not 2d.
It does not necessarily mean, that there is an additional dimension, in which the manifold is curved - it could be flat (2d analog - a cilinder or a cone are topologically flat surfaces, believe it or not), as well as curved, and the additional dimension (which, presumably, would contnain the center of the "surface", like in the example with a sphere) is only necessary to help you imagine such a manifold - it does not have to exist - a 3d manifold does not have to be "embeded" into some higher-dimensional space - it could just exist all by itself.

Another, black hole at the center of the universe? No, There's no black hole in the center of the universe. You might have noticed the massive object in the center of the solar systems and the galaxy. Massive objects make other bodies circle it. Therefore, the solar systems orbit the black hole at the center of the galaxy. However, the universe, is not orbiting a black hole because it does not have a center. If there was a black hole in the middle of the universe, it would not be able to capture all the mass in the universe because the gravity decreases with the distance. So, for a gravitational field to cover the whole universe, it would need to be massive. More massive than a black hole.

nice question. But first let me tell you that there was only an ASSUMPTION, a HYPOTHESIS that a black hole exists in the centre of the galaxies to claim that all heavenly bodies revolve around the centre of the galaxy. Although it isnt proved but its the best explanation till date of the theory of revolution of the planets. Who knows what the vastness of the universe hides from us.
As far as your question is concerned, according to the bigbang theory, the universe expands because of being hit by cosmic background radiations on its end which were originated at the time of origin of the universe.The black hole at the centre of the universe (as you say there is one) should pull them but to tell you the truth, neither the black hole theory nor the big bang have been scientifically proved but the anatomy of the universe proposes to humans that this is the most liable thing which could've happened. So, lets meet at NASA 20 yrs later and have research on it after i win my nobel prize(s)

yes friend this is very good and very interesting question .
but this is not known to any astronomer or astrophysicist that our
universe is orbiting in a very huge massive black hole if this is
true then all galaxies should not expand from each other but this
is happening thats means the theory of super massive blackhole
is wrong. but super massive black hole exists in our own galaxy
by which all stars revolving the galaxy this is also observe in our
nearest galaxy andromeda this can be said that every galaxy
could have its
one super massive black hole. but by my conclusive of universe
is that one day will come when all matter of the universe collapse
in a single point from where it was begin.

Black Holes exist at the centers of the galaxies not at the center of the universe.
The universe is still expanding due to the inertia forces of Big Bang.

A black hole is merely a collapsed star. By that I mean a star has condensed so much in produces enough gravitational pull that light cannot even escape its gravity. Thus giving us the illusion that there is a void at that spot.
If there is a center of the universe,all mater should still be expanding from it due to the big bang that started it all.

well black holes are present where ever there is concentration of matter in space..u would find them near new born stars as well..since most of the galaxies have an active centre, thats the reason for them being there..rotation of galaxies is irrespective of black hole..coming back to centre of universe..well its expanding for sure and the far the galaxies the faster they are moving away from us..there are far away galaxies moving so fast that we ll never be able to see the light coming from them..so the finding centre of universe is highly improbable..

The is no black hole at the center of the universe because there is no center of the universe. Read and listen to the link below.

If I think exact logical a black hole in the center is against the expansion.
Both together is not possible!

It will take a while but after the big bang has quit expanding in another 100 billion years the huge black hole in the center will suck all matter back into it. Then space and time will be altered and all matter will be destroyed. Guess what happens then? bam-Another big bang and history repeats itself for the google to the google power time. Happy infinity to you.
