Our universe is a name for the universe we humans currently inhabit. This includes the individuals who contributed to this wiki. As far as we are aware, our universe is the only observable and measurable space, though this may change in the future.
While the entire universe is still a mystery, what we can gather about our observable universe is that it contains 3 spatial dimensions and 1 temporal (time) dimension and is a total of 93 billion light years in diameter. As far as we have been able to determine, there has been no sign of life except for us (yet).
It is possible that the universe is indeed infinite. Though the Big Bang theory would suggest that at one point the universe was compressed into a small point which then "exploded" into the surrounding nothingness; something like this could still have happened if our universe were infinite.
The measurable space we call the "Universe" could have been compressed into a point within a larger infinite space before simply expanding (a process which obviously continues to this day). However the more our universe expands, the longer it takes light to reach our planet, meaning unless we begin to expand ourselves further throughout the universe it will take longer and longer to discover more of the whole universe.
Other names for this space are "The Known Universe" or "Reality", though the latter term can be applied to everything that exists whether or not humans are aware of it.
Some people think there is a Multiverse. If there is, then this wiki would live.
