Physicists claim they may have found a long-awaited explanation for dark energy, the mysterious force that's driving the accelerated expansion of the universe, a new preprint study hints. Their ...

The proof of the existence of parallel universes has long been hindered by the core issue of "unobservable and difficult to empirically validate." Traditional theories often rely on mathematical ...

(NewsNation) — Theoretical physicist Dr. Michio Kaku supports the concept of parallel universes, but he says people shouldn’t get their hopes up about meeting their doppelganger in another dimension, ...

The largest-ever 3D map of the cosmos hints that the dark energy that’s fueling the universe’s expansion may be weakening. One community of theoretical physicists expected as much. On the morning of ...

(via Sabine Hossenfelder) According to a growing body of data, dark energy is not constant. Instead, physicists claim, it’s slowly getting weaker. This has understandably shaken our understanding of ...

The original version of this story appeared in Quanta Magazine. String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a ...
