There's Something Strange Beyond The Edge Of Our Universe

There are lots of theories about what lies beyond our universe. Some say it's just our universe, no matter how big or small. Others say that there may be billions more universes out there waiting to be discovered by us. And one theory says that everything we can see and anything we can't see is actually only a tiny part of a much larger reality.

Are there other universes that exist outside of ours? Could we go back in time or forward through time, or even travel through other dimensions? The possibilities are endless, and it's all a part of exploring the universe!
