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 ...

On January 22, 2025, physicists unveiled a groundbreaking discovery that could revolutionize our understanding of the ...

Most of today’s leading theoretical physicists have a shared perspective about what the next revolution in physics will look like. They think reconciling Albert Einstein’s general theory of relativity ...

If so, laws might change when the universe itself changes phase. In the early universe, as temperatures and densities shifted, forces split apart from a unified origin. What we call “laws” may be like ...

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The idea that space-time exists is no more ...

Physicists have determined that most of the universe is dark matter -- invisible to us but affecting the universe anyway.

The elusive Higgs particle has the power to undo physics as we know it. The fact that it hasn't could have big implications about the nature of the universe. When you purchase through links on our ...

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 ...

Anyone who has seen the classic rabbit-duck optical illusion knows the magic and confusion of duality. One might see a duck facing to the left with its bill hanging slightly open or a rabbit with its ...

A fringe new theory suggests that time is the fundamental structure of the physical universe, and space is merely a byproduct. According to Gunther Kletetschka, a geologist — not a physicist, you’ll ...

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time literally no longer make sense." A team of scientists has developed a recipe for ...

Artificial intelligence (AI) systems, particularly artificial neural networks, have proved to be highly promising tools for ...
