Mike asked the Naked Scientists:
   
Is there a black hole at the centre of our Universe?

I imagine that our Universe was significantly altlered by the immense gravitational force which existed 14 billion years ago, before the big bang.

That gravitational force probably is responsible for the vacuum of space.

When the big bang occurred, did it leave a black hole similar to when a star explodes?

Thanks
Mike

What do you think?

There is no "centre" to the universe as far as is known. The big bang idea is an expansion of 4 dimensional space-time rather than an explosion in empty space. There is no special point in the unverse at which the big-bang took place. The best analogy is to think of the universe as the surface of a balloon that is being blown up. All the points on the initial tiny balloon are moving apart as the balloon expands.

It is thought that galaxies may have a massive black hole at their centres, including our own galaxy.

That balloon analogy is cool, haven't heard it before.  First post!

There are really biig black holes in all galaxies it seems. But as we can't speak about a center to The universe?
