There are many types of spacetime within physics, the same way there are infinite dimensions in math. Some spacetimes are ...

A new computational simulation of the early universe has revealed a fundamental, unbreakable geometric limit to the fabric of spacetime, dubbed the "Metric Wall." Discovered by independent physics ...

A new theoretical framework shows how subtle fluctuations in spacetime could be detected using existing interferometers.

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

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 ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime fluctuations"—tiny, random distortions in the fabric of spacetime that appear ...

For more than a century, physics has treated space and time as the smooth stage on which the universe unfolds, a flexible fabric that bends but never breaks. A new wave of theories is now challenging ...

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 ...

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 ...

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

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 ...
