I'll go grab my tape measure and be back to let you know...
Forever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever some more.
I mean, really... it goes a long, long way... or then again... the short answer is:
Space goes and goes and goes until it hits something. Really, think about it.
The extent of space can be characterized by the time 'space' has been in existence. In the case of our Universe, the current evidence shows that the Universe is approximately 13.75 billion years old, give or take a few hundred million years. However, this is only the extent of the known Universe, what we can see or infer from what we do see. Also, from General Relativity, we know that the Universe is still expanding - space itself is expanding. There are a variety of methods used to calculate both the age and expansion rate of the Universe and equally as many theories about the accuracy of each. When we look at the Cosmic Microwave Background we are seeing light that has been in the Universe since the beginning of time as we know it, essentially we are seeing the edge of the Universe in a somewhat abstract kind of way.
Be careful "Right On Time", wherever you measure you will always end up where you started, might take a few years as well.
Our problem is that we are stuck in three dimensions and time is relative to speed so no matter how we tried we would never find an ending as it does not exist. Certainly not in three dimensions.

I've put this into the philosophy forum because I'm interested in what those who ponder the meaning of the cosmos would consider the ramifications of the answer to be.We talk of the Space-Time Continuum. We know the following:Cosmologists tell us it would be impossible to go back in time because...

Do you wonder about the basic shape of the universe, which is ever expanding?As far as science reveals and all that we can see, everything is ball shaped or rotund, could our Universe also be this shape, as well?
