It could be the weirdest and most embarrassing prediction in the history of cosmology, if not science.Dang.. I knew I was insignificant but a "momentary fluctuation in a field of matter and energy"! :)
If true, it would mean that you yourself reading this article are more likely to be some momentary fluctuation in a field of matter and energy out in space than a person with a real past born through billions of years of evolution in an orderly star-spangled cosmos. Your memories and the world you think you see around you are illusions.
There is more oddball speculation in this theory...
The basic problem is that across the eons of time, the standard theories suggest, the universe can recur over and over again in an endless cycle of big bangs, but it’s hard for nature to make a whole universe. It’s much easier to make fragments of one, like planets, yourself maybe in a spacesuit or even — in the most absurd and troubling example — a naked brain floating in space. Nature tends to do what is easiest, from the standpoint of energy and probability. And so these fragments — in particular the brains — would appear far more frequently than real full-fledged universes, or than us. Or they might be us.
Read the details at the article, if interested. Makes for some fascinating sci-fi-ish leaps of imagination for sure but who said life is simple. Jokes aside, even Einstein's relativity theories sound sci-fi-ish to me and those are pretty well proven! These theories are still evolving and could well be proven wrong by someone else down the road or maybe we are really fluctuations!
