Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...

It’s one quantum leap for mankind. Parallel dimensions are no longer restricted to Marvel flicks. Google’s cutting-edge quantum chip Willow has prompted discussions among scientists about the ...

Google’s new quantum computer chip, named Willow, is able to run computations so complex that it would supposedly take the world’s fastest supercomputers the entire lifetime of the universe to ...

There may be another universe just a millimeter away from ours, hovering in an extra, hidden dimension. At any moment this second universe (or “membrane,” in M-theory—a relative of superstring theory) ...

Multiple universes and parallel worlds are all the rage in film and TV these days from the Marvel cinematic universe toStranger Things. But multiverses are more than just fiction, many scientists are ...

Halpern (Flashes of Creation), a physics professor at Saint Joseph’s University, delves into the multiverse in this thought-provoking if challenging offering. He opens with a superb introduction to ...

I can’t be the only one here displeased by our current timeline. It’s pretty hard to experience endless COVID, debates about whether it’s genocide or just a little ethnic cleansing, and climate change ...
