"scientists have confirmed the existence of a parallel universe." do you think this story will go viral?

I believe so, YES.

What makes any story go viral will solely depend on the subject matter, mental calculations, and how others might like it. When it comes to matters like the existence of parallel universes, this subject has, since time immemorial, seemed like something cooked up by science fiction. The idea that we live in a multiverse that consists of an infinite number of parallel universes has in a very long time been considered a possibility. To wake up in the morning to news like "Scientists have confirmed the existence of a parallel universe”, will surely go viral
