According to the team, the new approach can explain how the universe's initial inflation can naturally arise. But it comes ...

Gravity is a basic force that affects everything we experience. Watch as a flat earther attempts to explain it without using gravity at all. The explanation starts confidently, then slowly shifts as ...

Researchers say a new theory tackling the Big Bang could reshape how physicists think about the earliest moments of cosmic history.

For decades, astronomers have been puzzled by strange “zebra stripe” patterns in radio waves from the Crab Pulsar — bright bands separated by complete darkness. Now, new research suggests the answer ...

Dark matter is some kind of substance that has gravity—it holds galaxies together—yet cannot be directly seen with any ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

Could the universe have hidden dimensions we’ve yet to detect? The idea of extra dimensions has intrigued physicists for over a century, and while there’s no solid evidence to prove their existence, ...
