If we assume that the universe is infinite, which seems quite probable, it is easy to think that beyond the horizon of our universe there may be other regions of space similar to ours.
How can there be something beyond this universe if it is infinite? 😅
There might be
other regions of spacedifferent from ours, but all in the same universe. Great read, but technical. Good job @mauromarGood appreciation but I meant our known and visible universe, our local neighborhood. :-)
