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

If true, the idea would blow past one of physics’ most sacred limits: that parallel versions of reality can never talk to ...

Neutrino particles have extremely small masses, yet there are so many of them that they carve out the large-scale structure ...

Foundations in science and physics exist at the very core of the Netflix's hit show “Stranger Things," demonstrating to audiences for over a decade that our universe may be "stranger" than we care to ...

If recent discoveries that dark energy is evolving hold any water, our Universe will collapse under its own gravity on a finite timeline, new calculations suggest. Based on several recent dark energy ...

Cosmologists have long treated black holes and the Big Bang as separate extremes of physics, one swallowing light, the other birthing space and time. A provocative line of research now suggests those ...

The brightest quasar ever seen in the young cosmos is powered by a black hole that appears to be breaking the universe’s own ...

The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when all of space, time, and energy were born from a single infinitely dense ...

A new JCAP study tests an “emulator” to reconstruct the large-scale structure of the cosmos If you think a galaxy is big, compare it to the size of the Universe: it’s just a tiny dot which, together ...
