Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

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 doomed star spiraling into a supermassive black hole has given physicists one of their clearest looks yet at how gravity ...

Astronomers have observed a star wobbling in its orbit around a ravenous supermassive black hole that is ripping it apart and ...

Astronomers have detected spacetime itself being dragged and twisted by a spinning black hole for the first time. The ...

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 ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths ...

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 ...

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 ...

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 ...

Champaign-Urbana art lovers and physics enthusiasts alike gathered at the Link Art Gallery Monday evening to explore physics-themed projects created by students from academic backgrounds across the ...
