For more than a century, physicists have suspected that the familiar three dimensions of space and one of time might be only a sliver of reality. Extra dimensions, if they exist, would not just be a ...

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) ...

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 ...

Below, Halpern shares five key insights from his new book, The Allure of the Multiverse: Extra Dimensions, Other Worlds, and Parallel Universes. Listen to the audio version—read by Halpern himself—in ...

Interest in the multiverse theory, suggesting that our universe is just one of many, spiked following the release of the movie "Everything Everywhere All At Once." The film follows Evelyn Wang on her ...

Parallel universes and multiverses are an interesting concept to tackle in art. The idea that there is a universe like ours existing at the same time and under different conditions and rules is pretty ...

Paul Halpern is a professor of physics at Saint Joseph’s University, Pennsylvania and author of books including The Allure of the Multiverse: Extra dimensions, other worlds, and parallel universes.

In 1919, physicist Theodor Kaluza hypothesized that extra dimensions might solve some outstanding problems in physics. And while we haven't found any evidence yet for anything outside our normal ...
