Plenty of groups have been theorizing about primordial black holes (PBHs) recently. That is in part because of their ...

A 'potentially hostile' alien object speculated to be a probe could prove a major theory shared by Baba Vanga and 'Living ...

The theory assumes that all universes behave similarly, but it does not account for the complexities of general relativity or the potential influence of quantum randomness on macroscopic scales.

This isn’t to say Trump hasn’t generated or amplified any conspiracy theories. He obviously has. It is simply meant to note ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

In some models, alternate realities bubble out from cosmic inflation or form across vast string theory landscapes. Many-worlds, by contrast, keeps its universe clones close—unseen, yet superimposed.

"The theory is not yet capable of addressing those major challenges, but it has potential to do so in the future," Partanen said. Experimental verification may prove even more elusive.
