Hubble has detected an estimated 80 billion galaxies (extrapolating from the small patch it has observed) in the observable universe, so its more that the 80 billion. That means, with the 100 billion stars in the Milky Way Galaxie, that's 80 billion times 100 billion number of stars, or more (in the observable universe).

There at least around 100000000000 (a hundred billion) galaxies in the Universe (this estimate is based on the findings of the Hubble Ultra Deep Field observations, so the actual number is almost certainly higher than this, by how much no one knows).
To go a little farther, these galaxies probably contain an average of about 10000000000 (ten billion) stars each, so that makes 10^23 stars in the Universe. Current estimates say there are probably about two or three planets per star, on average, so let's call it 2*10^23 planets in the Universe. And we're living on ONE of them. Makes you feel pretty small, doesn't it? :P

The usual estimates are all about 100 billion galaxies. But there's something else to consider.
When the universe was formed, it expanded very rapidly for a short time. That expansion carried most of the universe so far away from us that we can never observe it, no matter how good we make our telescopes. So there are actually trillions of galaxies, most out of sight.

A logical deduction would have to be an infinitesimal number, or in other words, endless.
When you unlock your perception, you will have to realize that space is never ending. Oh it does you say, well where does it end, and what is on the other side of the ending point? A solid wall, how deep is the wall, what is on the other side of the wall
.....see where I am going with this.
Some of our supposed brains, are very restricted in their thinking and live in a match box world, as they limit everything as relates to their limited ability to perceive anything bigger than their small mind will permit.

according with john black. galazies are generally everwhere. consider this aroud the our sytem exist more than 34. trillions. so we can assume that the number is uncaountable. don't you think?

Hi. At least billions.

More than any one person will ever know. Scientists discover more and more everyday and that will never stop.
