If this scenario plays out, “the world as we know it would collapse like a house of cards,” says one theoretical physicist.

The findings not only relieve a conflict between astronomical observations and the best, proven model of the evolution of the universe since the Big Bang, they also suggest that the massive black ...

Scientists recently found that dark energy, the mysterious form driving the accelerating expansion of the universe, could be weakening over time. The findings could undermine the existing standard ...

Current models say the universe expands evenly in all directions, with no sign of rotation. This idea fits most of what astronomers observe. But it doesn't explain the so-called "Hubble tension ...

Over billions of years, the universe has transformed from a simpler state into an intricate cosmic web, but new research ...

This mismatch, known as the Hubble tension, has shaken confidence in the model that’s long explained how the universe behaves. Now, a new study proposes something bold. What if the universe isn ...
