Quote of the day by Newton: 1915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 ...

Pushed down to a certain scale, the laws of physics seem to fall apart. Astrid Eichhorn, a leader in an area of study called asymptotic safety, thinks we just need to push a little further.

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

Shaped by a different biology or culture, other intelligent civilisations – if they’re out there – might understand the ...

Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned ...

A physicist proposes that consciousness is the fundamental basis of reality, with matter and spacetime emerging from it.

Superluminous supernovas are the brightest stellar explosions in the universe. Astronomers may have found a mechanism that can trigger these events.

Ashoke Sen might be one of the quietest geniuses in physics. Born in Kolkata in 1956, he grew up fascinated by abstract mathematics and theoretical pu.

Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of ...

For the past two decades, scientists have wondered about a bright, distinct striped pattern seen in radio waves emanating ...

Cosmic voids may seem like the emptiest places in the universe, stripped of matter, radiation, and even dark matter. But they’re far from nothing. Even in these vast empty regions, the fundamental ...

When black holes collide, the crash generates ripples in the fabric of spacetime—gravitational waves. Thanks to a global network of observatories—called the Laser Interferometer Gravitational-Wave ...
