We are all aware of our universe. We are taught about it in schools and colleges. Most people are fascinated by space, and we often see fictional movies, online casino games, books, and even clothing, often inspired by space and our universe. Our universe has been exhaustively studied over hundreds of years, and there are still unanswered questions about it.
Our universe is, as far as we know, only as large as light has been able to travel in the 13.7 Billion light years since the Big Bang marked its creation. We could assume, then that our universe may be as large, if not larger, than double that size. It is estimated to be about 90 billion light-years in size.
But what if our universe isn’t the only one? Could there be many universes, all co-existing in an infinite environment?
If our known universe is finite, then there is a possibility that other universes exist. Collectively, all these universes are called the multiverse, and there are theories to promote and dispel the possibility that we are part of a multiverse.
Let’s look at some theories:
To the average person on Earth, it doesn’t really make any difference whether the multiverse exists or not. If it does, it is highly doubtful that anything sent from Earth will ever be able to get there. We are still heavily engaged in exploring what little parts we know of our own universe.
Scientists and astronomers are discovering more and more about our known universe all the time. Theories are confirmed or destroyed by scientific evidence as our searches develop.
Outer space exploration is fascinating and always has been. What mankind has discovered about our universe in the last fifty years, is sure to be surpassed by more discoveries in the future.
For now, the multiverse exists only in theories. And in our imagination
