What can go beyond infinity?

infinity isnt a set number.  nothing.

space doesn't really have limits that we'll ever reach, but yeah there are MANY others planets and solar systems in our galaxy, let alon the other 51351351354 (to the 80 trillionth power) galaxies. it's infinite.

The universe has no end, just as the surface of a sphere has no end. In terms of the surface you can't describe its end, only in terms of a higher dimensional geometry. In that sense, "beyond" is meaningless since it is a term to relate to the same dimension as the universe. It's like "beyond the end of the world" for the surface of Earth -  there is no end, and at some time you might return to where you started from.

Actually this will be unknown forever cause by that time the universe will reach to its "ultimate fate"\nby the way, you can go here to know...\nhttp://en.wikipedia.org/wiki/Ultimate_fate_of_the_universe

Outer space extends to the end of the universe. Further, the universe is constantly expanding. No-one knows if anything is beyond the end of the universe.

the question is, what is there to block the universe from expanding?  The theory of going out one end and coming out on the other would break any and all laws of physics and space that we hold today, which, is a possibility, but not a likely one.  Also, the concept of infinity doesnt need to follow regular laws of mathematics, because infinity is not a number as some poeple have been treating it here.  Infinity is a concept, where infinity means increasing by an infinite amount, as in, ongoing and never ending...it is a concept, not a number.  So, how can the universe go on forever? it may not be able to, but with our current laws of physics, unless there is soemthing with an equal or greater power to stop the space matter and such that is expanding in light years, then the universe will never stop expanding.  Before the "big bang THEORY", (again, theory, not law as someone was using it to make their point) thee must have been some type of area occupying what our current universe is eating up, since again, by our current laws, you cannot make something out of nothing, so, my thought would be that the universe will expand as far as the previous area which it is expanding into, because it cannot expand to make something our of nothing at all, or so our current laws say...

cant stop now..must look forward...to infinity and beyond!

possibly its infinite\nbut its an argument you will find quite interesting to discuss with REAL people. im no astronomer but a thirteen year old student.i can tell you that there is the M-theory which states of parallel universes.the string theory says that there is a 12th dimension which is outside the boundary of this universe. Now we ask what is beyond that? its hard to answer. But we should never let our Heads be larger than our Hats!

B to the infinity plus one power

Outside the space there is more of Space\nSpace is Infinite

a curve extending to infinity from zero...

there are infinity number of Qs. so there is no end.

The Universe is thought to be 'finite but bounded'. That is, it does not come to an end anywhere but somehow loops around again far, far away. Another example of a finite but bounded shape is the surface of a bubble, a sphere. It has definite area and size but there are no edges to its surface, no place to call a "beginning" or "end" that is not arbitrary.

Isn't infinity by definition incomprehensible, at least to the senses?

as opposed to other numbers, infinity is not a number but a mathematical concept like zero,1 and any other number. It does not necessarily means a huge number. It is associated with the concept of limit in Analysis. u can get infinitely close to 1 but not be 1 exactly, or u can add up positive real numbers and never reach the biggest number. For example, 1/0 is meaningless. It cannot be handled. However, 1/n, with n getting infinitely close to 0, is a well defined concept in mathematics and is used constantly in calculus and analysis.\n\nHowever, u have notice, i did not give a mathematical definition of infinity. Because I cannot do it concisely and axiomatically. Look up some books on Analysis.

Its infinity of course

Well since infinity is not a number but; then I guess the largest number will have to be infinity  minus one
