A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

Friedmann accepted this new term but pointed out a radical alternative: the universe did not have to be frozen. He argued that Einstein’s static universe was merely a special case and that the cosmos ...

A decades-old idea is quietly regaining attention in theoretical physics: ancient structures embedded in the universe’s ...

Cosmic strings and Einstein’s relativity raise the theoretical possibility of time travel within modern physics.

In a few days Paste will stake its claim on who the “greatest guitarist of all time” is, but first we have to talk about the ...

One of the most striking outcomes of the surface-minimization framework is its ability to explain structural features that ...

Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

Primordial black holes could rewrite our understanding of dark matter and the early universe. A record-breaking detection at ...
