At the quantum level, the past and the future are indiscernible. That could have profound effects on the world we can see.

Not everything we knew about the universe is wrong. But not not everything. The Dark Energy Spectroscopic Instrument (DESI) ...

The groundbreaking findings throw established science into question, write Bernard J.T. Jones, Licia Verde, Vicent J.

Theoretical physicists James Hartle and Stephen Hawking, for example, proposed that rather than having a strict beginning as we would understand it, the universe evolved out of a "no-boundary" state ...

Instead, its expansion could wane, eventually leaving the universe stable. Or the cosmos could even reverse course, eventually doomed to a collapse that astronomers refer to as the Big Crunch.

When I was a kid, I was fascinated by the Powers of 10 video, which came out in the 1970s. Perhaps you remember it, with the narrator taking us both outward toward the fathomless end of the Universe ...

Recent research from the dark energy spectroscopic instrument (Desi) team indicates that dark energy, which drives the universe's expansion, is weakening. This significant finding challenges the ...
