Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

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 ...

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

A century after Albert Einstein sketched out his radical picture of gravity, astronomers have now watched a black hole ...

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 ...

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 ...

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 ...
