http://www.sciencealert.com/a-cosmologist-says-he-s-found-possible-signs-of-a-parallel-universe There was a time when this speculation was said to be 'impossible' by the science community too. That there was only one universe (only this one) and its infinite (how the heck would they know that??) ad nauseum. a self-centered view and that wasnt even science. Not much different than the belief the earth was the center of the solar system. It was just a belief or theory at best but theory on absolutely nothing just as well. How could anyone know when you cant even get out out of your solar system but you think you know whats past billions of light years which you cant even see.
