What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred years, physics has rested on two foundational theories. Einstein’s general relativity describes gravity as the curvature of space and time,

Astrophysicists have presumed for nearly a century that the universe will just keep expanding for all eternity, driven by an invisible force called dark energy. But new data suggest that this is unlikely to occur.

For decades, scientists have asked one of the most profound questions in existence — are we alone in the universe, or is our universe just one of many. This film explores the theories, evidence, and cosmic mysteries behind the possible reality of the multiverse.

He was a co-winner of the 2006 Nobel Prize for physics for finding the background radiation that finally pinned down the Big Bang theory.

Astronomy is, in essence, an exercise in inference. We cannot touch the stars, nor scoop up galaxies in a lab. Instead, we decipher the

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time.

Deep beneath South Dakota, scientists are closing in on one of the greatest mysteries in the universe — the true nature of dark matter. Using the world’s most sensitive detector, the LUX-ZEPLIN experi

Progress in the foundations of physics is moving slowly. And yet it moves. Today I look at the five biggest problems in physics, what their status is, and how long it will ta

The universe is approaching the midpoint of its 33-billion-year lifespan, a Cornell physicist calculates with new data from dark-energy observatories. After expanding to its peak size about 11 billion years from now,

Sometimes, the simplest explanation is the best one," Professor Gupta said. "Maybe the universe’s biggest secrets are just tricks played by the evolving constants of nature."
