Black holes might be defects in spacetime

A team of theoretical physicists have discovered a strange structure in space-time that to an outside observer would look exactly like a black hole, but upon closer inspection would be anything but: they would be defects ...

Unraveling the mathematics behind wiggly worm knots

For millennia, humans have used knots for all kinds of reasons—to tie rope, braid hair, or weave fabrics. But there are organisms that are better at tying knots and far superior—and faster—at untangling them.

Could this copycat black hole be a new type of star?

It looks like a black hole and bends light like a black hole, but it could actually be a new type of star.

Melting glasses: The glass-to-liquid transition

The process of liquid-to-glass transition is a complex procedure in science, as is the glass-to-liquid transition known as glass melting. In a new report published in Science Advances, Qi Zhang and a research team in physics ...

Hubble monitors changing weather and seasons of Jupiter and Uranus

Ever since its launch in 1990, NASA's Hubble Space Telescope has been an interplanetary weather observer, keeping an eye on the largely gaseous outer planets and their ever-changing atmospheres. NASA spacecraft missions to ...

The multiverse: How we're tackling the challenges facing the theory

The idea of a multiverse consisting of "parallel universes" is a popular science fiction trope, recently explored in the Oscar-winning movie "Everything Everywhere All At Once." However, it is within the realm of scientific ...

Is there a multiverse?

Interest in the multiverse theory, suggesting that our universe is just one of many, spiked following the release of the movie "Everything Everywhere All At Once." The film follows Evelyn Wang on her journey to connect with ...

New possibilities in the theoretical prediction of particle interactions

How does the world look like at the smallest scales? This is a question scientists are trying to answer in particle collider experiments like the Large Hadron Collider at CERN in Switzerland. To compare the results of these ...

The multiverse: Our universe is suspiciously unlikely to exist—unless it is one of many, says physicist

It's easy to envisage other universes, governed by slightly different laws of physics, in which no intelligent life, nor indeed any kind of organized complex systems, could arise. Should we therefore be surprised that a universe ...

The legacy of the Majorana Demonstrator (Update)

For nearly six years, the Majorana Demonstrator quietly listened to the universe. Nearly a mile underground at the Sanford Underground Research Facility (SURF), in Lead, South Dakota, the experiment collected data that could ...
