if space is limitless and it is expanding from a central point (IE the big bang) where is it expanding to?

Answer 1

(in his best Buzz Lightyear voice)
To infinity, and beyond!!!

Answer 2

According to the Big Bang theory, we should regard space as a very long row of hills and valleys. The space will expand until gravity will be more powerful than the forces of the initial explosion that caused the expansion of the point in which an infinite mass was concentrated and then the whole universe will shrink to the dimensions of the initial point and explode again.

Answer 3

Quoting: {Multiverse
The idea that the universe that we can observe is only part of the whole physical reality led to the definition of 'multiverse, the set of multiple possible universes.
The term "multiverse" was coined in December 1960, by Andy Nimmo, then vice chairman of the British Interplanetary Society, Scottish Branch, for a talk to the branch on the many-worlds interpretation of quantum physics which had been published in 1957. This was given in February 1961, and the word with its original definition, "an apparent universe, a multiplicity of which, go to make up the whole universe" was then first used. This was because, at the time, the definition of the word 'universe' was "All that there is" and etymologically one cannot have "Alls' that there is". "Uni" means one, and "multi" means many, so this meaning allowed for many multiverses.} - reference.com

Lisa Randall and Raman Sundrum have posed a 5-dimensional multiverse with our local universe exisiting as a 4-dimensional "sinkhole" in that 5-dimensional space. Their theory can soon (2007?) be tested when the Large Hadron Collider goes online in Europe.

Answer 4

Space *is* limitless, but *it* is not expanding (at least in my opinion). It is the particles, the stars, the dust, etc. that are moving in to occupy the space that is already there. Thus, you might say that the expanse of particles, etc. that came from the big bang is expanding as its "borders" are moved as individual elements in the expanse continue to travel outward from a central point.

Answer 5

Our galaxy as we know it , is expanding outward into the vast expanse of space due to the big bang theory. Other galaxies however are not expanding , but are actually collapsing in on themselves such as referenced as black holes which are stars that have drawn whole systems into them. I believe that all galaxy systems depending on their age are either expanding or contracting . To answer this question of where it is expanding to would be to know at what time this galaxy is in development. You must first know when our sun will burn out and become a dead star.
Albert Einsteins general theory of relativity describes gravitational interaction between all matter. Our universe at one time was very compressed and this matter (compressed) predominated over anti matter and formed nuclei.and after millions of years there is a nuclear reaction of these atoms and radiation is formed . Support of this theory includes the abundance of helium , hydrogen, and lithium in our solar system .Cosmic background radiation also supports this theory
which also explains the red shifts of galaxies as resulting from the expansion of space.

Answer 6

It's impossible to say. We cannot see beyond our universe, so we don't know if the universe is expanding into something else (a multiverse?) or simply creating existance as it expands. The problem lies in penetrating the background radiation that lies at the edge of the 'observable universe' which is, unfortunately, barely able to be detected, let alone studied in great detail.

Answer 7

this is actually a common misconception about the big bang. the theory says that everything, even space-time, originated in the big bang. and space-time may be something like the two dimensional surface of a sphere. the universe is finite yet has no edge (boundaryless) and no center, and nothing exists "outside" space-time. to quote a dead writer, "there's no there, there". the big bang was the entire universe. everywhere in the universe was once the big bang.

Answer 8

According to Einstein, the Universe is finite, therefore, Space is expanding into its allocated area. When it runs out of 'expansion area', it will effectively snap back like a cosmic elastic band.

Answer 9

It justs expands larger and larger, if there is a point or wall then what's behind that.
I am astrophysicist and I can only theorise on things, I don't know all the answers.
EG. Who is God's father, I would never want to ask that to that power but that's what we don't know, do we?

Answer 10

We do not know that "space" is expanding. We know that the Universe is expanding. Perhaps one day it will collide with another universe.

Answer 11

All the solar systems/galaxys etc. are just getting further and further apart. One day all of the energy from everything will be so spread out that everything will be stone cold and there will no longer be any life - unless something seriously cool happens!!!
