It is common theory that the universe began with the Big Bang 13.7 billion years.
However, as you can only see as far as light has traveled in that time, it can actually make the edge of the universe. Could it be that the universe is infinite? Is there any way to find out what the shape of the universe really is? Can we find the edge, to discover what might lie beyond it, and maybe even discover a universe next to ours?
With the exception of mathematicians and physicists, most people do not like infinity. We like to know the extent of things. We can wrap your head around the measurements. Your car can be 10 feet long, home is 2,000 square meters, the U.S. national debt is … Well, some things are more limited than others.
But what about our universe? It’s great. How big and how it is consumed much of the debate in the world of cosmology. Calling our universe is important because most accepted theory today in the cosmos, string theory says ours is not just a bubble of space-time between an infinite army of other parallel universes and bubbly. They call this a multiverse intelligently, and is more complex than most people will want to know. List of all episodes here: through the hole.
