big bang

Tendrils of galaxies up to hundreds of millions of light-years long may be the largest spinning objects in the universe, a new study finds.

The Dark Energy Survey just released its most comprehensive results. But did they really prove Einstein wrong?

Scientists have recreated the first matter that appeared after the Big Bang in the Large Hadron Collider.

Astronomers try to solve the mystery of antihelium by searching for antistars.

Physicists have long been unable to describe what happened just after the Big Bang when a teensy blip ballooned into the universe, a process called inflation. We may know why.

An ultra-high-resolution simulation of a tiny slice of the universe — a million times smaller than a proton — has revealed the very first structures to ever exist.

Believe it or not, physicists are attempting to understand the universe when it was only a handful of seconds old.

Cosmologists simulated 4,000 versions of the universe in order to understand what its structure today tells us about its origins.

A weird, super-powerful particle that's not truly a particle could have dominated the universe when it was just a second old, releasing a flood of ripples that permeated all of space-time.

A mysterious "kick" in the early universe may have produced more matter than antimatter. And that imbalance may have also led to the creation of dark matter, researchers now say.
