A look at how scientists have studied gravity from Newton to modern physics, and why it remains one of the most complex ...

A new physics paper proposes modifications to Einstein’s theory of relativity that could solve one of the biggest issues ...

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

Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests ...

The collective gravity of countless neutrinos gently irons out the wrinkles in the cosmic web, preventing matter from ...

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 ...

Space weather can interfere with spaceflight and the operation of satellites, but the phenomenon is very difficult to study on Earth because of the difference in gravity. Researchers effectively ...

Now it seems that wormholes, those shortcut tunnels through time and space that Albert Einstein theorized and that science fiction depicts as portals between two distant galactic points, are at the ...

It is the partner that makes dancing as we know it possible. So to be a dancer in a float tank -- which uses the buoyancy of saltwater to approximate weightlessness -- is both bewildering and ...

An overview of some unresolved questions in modern physics, including challenges in understanding gravity, quantum mechanics, and the structure of the universe. Dietitians say you shouldn't take these ...

Humans living in space for months, years, or even generations will need to navigate sex in a zero-gravity world.
