I was just curious how many different "worlds" there are, if there indeed are any other than this one.

At least eleven dimensions exist, per Super String Theory. Here is a fun toy to play with to help visualize these multiple dimensions:

Of course, you must recognize, we live in a 4D universe. We cannot pin point the location of anything without specifying the equivalent of x, y, z, and t; where t is time, the fourth dimension. That is, we must specify both where and when something is to be exact.
There are several theories that specify more than four dimensions in order to get meaningful answers. String theory, for example, invokes ten or eleven dimensions, depending on which of the several views of the theory we are using.
So, "is it possible;" yes, but personally I think it's unlikely. I think it's more likely that when all is said and done, someone will come along and find out that all these extra dimensions are not necessary to unify the four fundamental forces of the universe.
That is, I believe nature is rather simplistic in what it produces; so all those extra dimensions are not needed to explain the universe we live in. Occam's Razor best describes it, "When there are multiple explanations for an effect, the simplest one is most likely the right one." [See source.]

It is not only possible, but widely believed by physicists that there are as many as 12 dimensions! This is what string theory and other modern physics is all about.
But why can't we see them? Imagine the 2D world of a stick figure on a piece of paper. He's free to move around up, down, left or right. Now take that paper and roll it into a tube. The stick figure is still free to move around in any direction, but we can see from the outside that his universe is quite different than before. Now tighten that tube as much as possible, so you have a nice thin tube. If you tighten the tube enough, the stick figure won't have much room to go left or right anymore, he can only go up and down. By curling the second dimension into a tiny space, we have effectively turn the 2D world into a 1D one.
This is how scientists explain where all the "extra dimensions" are in our real universe. They are crunched up so small wee can't experience them!

According to a physist named Brian Greene, there are many hidden dimensions. He believes in something called string theory. If I understand it right, a string is a super tiny (way smaller than an atom) point of moving energy. Many strings make up matter. Anyway, in his book Elegant Universe, he says there are as many as eleven dimensions. He also talks about space as a fabricthat rips, tears, and repairs itself at all times. Check out his book-- it's real science widely accepted by physists, not just silly junk science. :-)

A 1-dimension system is only meaningful if we have the concept of 2-dimensions. Similarly, a 2-dimensions system is meaningful only if we have the concept of 3- dimensions. So far and so on, there are infinite number of dimensions in the universe.

There are trillions of dimensions, and trillions of worlds with life on them much like earth. But we have no chance of visiting. Also some believe that the human body itself is in fact a universe of life.

According to string theory, there are about 11 dimensions more than we have now!
Here is a web site with some downloadable videos on it:

einstein proved that time is the 4th dimension, but u can not see it, feel it or so.Experts in Mathematics have also developed formulas that enable us to work on n dimensions

There just might be but I don't think that the human eye was made to see them. yooouuu never knoooww! It's like the twilight zone! lol

it is possibilities like this that make life interesting.
when someone tells you impossible just remind them
how many "impossible" things are now a part of daily
life.
