My curiosity question was: is there a parallel universe?
My answer came out to be no, but actually there are multiverses. A multiverse is “the simplest type of parallel universe.” Quoting from the article, “Welcome to the Multiverse!” on Newsweek.
As I was doing my research on parallel universes, not many results came up; until I looked on Newsweek. When I looked on Newsweek, I found this article called, “Welcome to the Multiverse!” and it was very interesting. It tells of how he got his information, and of whose theories that he uses. Like for instance “Greene introduced quantum mechanics and Einstein’s theories of special and general relativity”, that small part tells us a lot!
But, this article was actually for his book, and that I did not get a chance to find, much less read. Apparently in his book, (as this article tells me) “Greene describes nine different theories in which imply that we are living in a vast multiverse” again paraphrasing from the article. Another thing was the “Copernican Patter” which apparently occurs every 500 years.
OK, back to the multiverse thing. Another thing was that the multiverse seems to be “quilted” as Greene calls it. Another small detail, that I found interesting was that “our cosmic horizon is about 14 billion light years away” another sentence I am paraphrasing from the article.
But concluding the article was basically being told that there may be multiverses inside of other multiverses.
But concluding, the answer to my question, yes there are thousands of parallel universes.
