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

Physicists are quietly testing an audacious idea: that the mass of everything around us might not come from an invisible ...

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

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

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

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 ...

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 ...
