Until any theory is scientifically proven, there will be both skeptics and believers. It takes a lot of research, resources, and technology to take an out-of-this-world idea from science fiction to science fact. While there is some evidence supporting the multiverse or “parallel universe” theory, the subject continues to spark heated debate. Here are some of the brilliant minds on both sides of the argument:
To infinity, and beyond! Scientists like Stephen Hawking, Neil deGrasse Tyson, and Michio Kaku support the multiverse theory, and believe there was not one Big Bang, but multiple Big Bangs, which created multiple universes, including our own.
“There is no unique picture of reality.” – Stephen Hawking
Neil deGrasse Tyson:
“The Universe is under no obligation to make sense to you.” – Neil deGrasse Tyson
“I believe we exist in a multiverse of universes.” – Michio Kaku
This is it, folks. Skeptics of the multiverse theory include Steven Weinberg, Marcelo Gleiser, and George Ellis. Until imperical evidence is presented, these cosmologists remain critical of the idea of parallel universes and realities.
“As for me, I have just enough confidence about the multiverse to be the lives of both Andrei Linde and Martin Rees’ dog.” – Steven Weinberg
“We strive toward knowledge, always more knowledge, but must understand that we are, and will remain surrounded by mystery.” – Marcelo Gleiser
“Nothing is wrong with scientifically based philosophical speculation, which is what multiverse proposals are. But we should name it for what it is.” – George Ellis
