Einstein's equations have withstood every experimental test for more than a century; however, according to one philosopher, ...

A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this ...

What if our biggest idea about reality is built on a hidden misunderstanding? A new philosophical look at space-time ...

Bell's theorem, the well-known theoretical framework introduced by John Bell decades ago, delineates the limits of classical physical processes arising from relativistic causality principles. These ...

Most people picture a black hole forming the same way: a massive star runs out of fuel, collapses under its own gravity, and ...

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 ...

Scientists have described for the first time how spacetime could crystallize into a tiny black hole.

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 ...

If you wave your hand in front of your face, you won’t notice anything particularly interesting. Perhaps a gentle waft of air against your cheek – that’s about it. No epiphany. No major sign that ...

The quantum revolution in physics — whose 100th anniversary we have just celebrated — taught us that at the most basic level the world is bizarrely different than it seems. But, we appear to only have ...
