The origin of our Universe remains one of the greatest enigmas of science, a question that seems to defy the limits of our physical understanding. For decades, cosmologists have struggled with

The universe exists because matter and antimatter are not good friends. Is there a scientific reason why the universe exists? In other words, what is the science of why there is anything at all, instead of only nothing?

A backward, mirror universe could explain the existence of dark matter. If an anti-universe exists, it would run backward in time, before the Big Bang. Dark matter, then, could be right-handed neutrinos implied by the mirror universe.

If you buy through a BGR link, we may earn an affiliate commission, helping support our expert product labs. The fate of the cosmos may be a bit different than previously expected. For years, scientists have talked about how the universe is always ...

That cosmologists cannot agree on one of the most elementary facts about the universe is striking enough. But that uncertainty produces others, too: it makes it impossible to calculate an exact age for the universe,

The first chemical reactions in the wake of the Big Bang have been recreated for the first time in conditions similar to those in the baby Universe.

The description of creation encourages both intellectual and spiritual connection with the divine essence. In contemplating the natural world—now understood through physics and science—we observe expressions of the principles of the Torah as revealed in Kabbalistic and mystical traditions.

From early experiments with lanterns to Einstein’s revelations about space and time, the speed of light has proven to be far more than a number: it’s the cosmic constant that defines reality.

Fast radio bursts (FRBs) last around a millisecond and in doing so encode otherwise unattainable information on the plasma which permeates our Universe, providing insights into magnetic fields and gas distributions.

“There’s a lot of meanings for ‘small,’” says Janet Conrad, a particle physicist at the Massachusetts Institute of Technology. “Like, I could say a cotton ball is ‘small’ because it’s very light. Or I could say a tiny metal ball is ‘small’ because its radius is very small, but it would weigh a lot more than the cotton ball.”
