The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

Spacetime itself would also need to be “quantized,” or broken down into constituent parts. This is what the notorious string theory attempts to do, as does loop quantum gravity, currently considered a ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...

For the first time, a group of physicists has written down a warp drive concept that does not ask the universe for impossible ...

Astronomers have observed a star wobbling in its orbit around a ravenous supermassive black hole that is ripping it apart and feasting on its stellar material. The observation is ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

For over a century, scientists have been intrigued to decode the perplexing scenery behind contemporary physics. It's been up for many years, and yet the experts still have no idea how to bridge the ...

A team of scientists has used X-ray and gamma-ray observations of some of the most distant objects in the Universe to better understand the nature of space and time. Their results set limits on the ...

How to build a particle collider the size of the solar system. To observe the quantum nature of gravity and of spacetime itself, we need a particle collider the size of the solar system. Or we could ...

One of the most awkward parts of writing a book is that, eventually, authors have to ask people for “blurbs” – the endorsements that you see on the cover of a book, encouraging you to buy it. I am now ...

In the 1900s, Albert Einstein unified the concepts of space and time, giving us a useful new way to picture the universe. At the start of the 20th century, physicists had a problem: The speed of light ...

Champaign-Urbana art lovers and physics enthusiasts alike gathered at the Link Art Gallery Monday evening to explore physics-themed projects created by students from academic backgrounds across the ...
