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 ...

Quasicrystals are orderly structures that never repeat. Scientists just showed they can exist in space and time.

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that describe gravity, quantum fields and the structure of spacetime now allow ...

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 ...

Current theories suggest that W and Z bosons acquire mass from interactions with the Higgs scalar field, but a new study suggests that the higher dimensional structure of spacetime could be the actual ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

The following essay is reprinted with permission from The Conversation, an online publication covering the latest research. Time feels like the most basic feature of reality. Seconds tick, days pass ...

When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

It feels so obvious that time moves forward that questioning it can seem almost pointless.
