There's some, but not overwhelming, evidence that dark energy is evolving. What would it take for a "Big Crunch" to be our cosmic fate?

For 13.8 billion years, the Universe has been expanding. But that couldn't have been the case for an eternity, and science has proven it.

We've long known we can't go back to infinite temperatures and densities. But the hottest part of the hot Big Bang remains a cosmic mystery.

Found by Hubble before JWST's launch, GNz7q looked like a mix of a galaxy and a quasar. Was it actually our first known "little red dot"?

Observations with the Hubble space telescope helped cement dark energy and reveal the Hubble tension. How are these two things so different?

Inflation's two main criticisms, that it can predict anything and that the "measure problem" remains unsolved, can't erase its successes.

As the Universe ages, it continues to gravitate, form stars, and expand. And yet, all this will someday end. Do we finally understand how?

As we gain new knowledge, our scientific picture of how the Universe works must evolve. This is a feature of the Big Bang, not a bug.

In this excerpt from "Facing Infinity," Jonas Enander examines how John Michell conceived of "dark stars," or massive bodies with enough gravity to trap light, all the way back in 1783.

With several seemingly incompatible observations, cosmology faces many puzzles. Could early, supermassive stars be the unified solution?

The Universe isn't just expanding; the expansion is accelerating. If different methods yield incompatible results, is dark energy evolving?

Throughout history, "free energy" has been a scammer's game, such as perpetual motion. But with zero-point energy, is it actually possible?

The Universe was born incredibly hot, and has expanded and cooled ever since. Could life have begun back when space was "room temperature?"

When it comes to our Universe's origins, scientists discuss the Big Bang, cosmic inflation, and other theories. Why doesn't "God" come up?

The measured value of the cosmological constant is 120 orders of magnitude smaller than what's predicted. How can this paradox be resolved?

The CMB has long been considered the Big Bang's "smoking gun" evidence. But after what JWST saw, might it come from early galaxies instead?

Originally, the abundance of bright, early galaxies shocked astronomers. After 3 years of JWST, we now know what's really going on.

In just its first 10 hours of observations, the Vera Rubin observatory discovered more than 2000 new asteroids. What else will it teach us?

For over 50 years, it’s been the scientifically accepted theory describing the origin of the Universe. It’s time we all learned its truths.

Massive galaxy cluster Abell S1063, 4.5 billion light-years away, bends and distorts the space nearby. Here's what a JWST deep field shows.

Is the Universe's expansion rate 67 km/s/Mpc, 73 km/s/Mpc, or somewhere in between? The Hubble tension is real and not so easy to resolve.

Different methods of measuring the Universe's expansion rate yield high-precision, incompatible answers. But is the problem robustly real?
