Big Bang Theory: The latest science and discoveries

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

New calculations suggest the universe was chaotic just after the Big Bang.

A new study on the rotation of the universe's first light could suggest physicists need new rule-breaking subatomic particles

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.

Scientists have taken a fresh look at the observable (expanding) universe and have estimated that it is 13.77 billion years old (plus or minus 40 million years).

Tracy Slatyer, known for hunting dark matter in our galaxy and discovering evidence of an ancient Milky Way explosion, has won a $100,000 prize funded by tech billionaires.

Strands in the intergalactic web

A few scant equations can explain a variety of phenomena in our universe, over vast gulfs of space and time. Here's a taste of just how powerful modern physics can be.

Could the structure of the universe emerge from the repetition of a simple rule?

A key signal for a certain kind of dark matter failed to turn up in a search throughout the Milky Way. Now scientists are disagreeing about what that means.
