Astrophysicists at the University of Chicago have developed physics-based models suggesting that dark energy could be ...

Theoretical physicist Alex Lupsasca is pushing for a space telescope to glimpse the thin ring of light that is thought to surround every black hole.

New strategies may soon allow scientists to test dark energy theories within our own solar system, linking cosmic-scale physics to local observation. Science advances through a cycle of proposing ...

Despite it’s comparative size to our star, it’s still the least massive object ever detected using gravitational lensing.

About 60 years ago, the original Star Trek series featured a technology called a “warp drive,” which allowed space travel at speeds much faster than light. Theoretical physicist and philosopher Albert ...

Physicists theorize our universe may have collided with another in the past, creating the Big Bang. Level two of the ...

Are we alone? It's one of the most basic questions of human existence. People have been trying to answer it for millennia in ...

Searching for clues in the Epoch of Reionization, scientists discovered that the universe was quite a bit warmer before the ...

Theorists have found that a “warm” version of cosmic inflation is consistent with known physics, linking it to the hunt for ...

In a remarkable feat of astronomical innovation, scientists have employed a unique “hack” on the Giant Magellan Telescope to ...

"They are the parents of all matter in the universe today, including our own bodies, while the knots can be thought of as our ...
