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

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 ...

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

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

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 ...

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 ...
