A Fast-Moving Star is Colliding With Interstellar gas, Creating a Spectacular bow Shock
Zeta Ophiuchi has had an interesting life. It began as a typical large star about twenty times more massive than the Sun. It spent its days happily orbiting a large companion star until its companion exploded as a supernova about a million years ago. The explosion ejected Zeta Ophiuchi, so now it is speeding away through interstellar space. Of course, the supernova also expelled the outer layers of the companion star, so rather than empty space...

Black holes may die differently than we thought
We still don't know exactly what happens when black holes die. Ever since Stephen Hawking discovered that black holes evaporate, we've known that they can potentially disappear from our universe. But our understanding of gravity and quantum mechanics isn't powerful enough to describe the last moments of a black hole's life.

Dark matter: our review suggests it's time to ditch it in favour of a new theory of gravity
We can model the motions of planets in the Solar System quite accurately using Newton’s laws of physics. But in the early 1970s, scientists noticed that this didn’t work for disc galaxies – stars at their outer edges, far from the gravitational force of all the matter at their centre – were moving much faster than Newton’s theory predicted.

Faster-Than-Light Travel Could Work Within Einstein's Physics, Astrophysicist Shows
For decades, we've dreamed of visiting other star systems. There's just one problem – they're so far away, with conventional spaceflight it would take tens of thousands of years to reach even the closest one.

Famous Higgs boson behaves just as expected, 'most comprehensive studies' confirm
The "most comprehensive studies" of the Higgs boson conducted to date reveal that the particle behaves just as expected and could help unlock some of the greatest mysteries of physics, including the nature of dark matter, scientists say.

Record-setting quantum entanglement connects two atoms across 20 miles
Researchers in Germany have demonstrated quantum entanglement of two atoms separated by 33 km (20.5 miles) of fiber optics. This is a record distance for this kind of communication and marks a breakthrough towards a fast and secure quantum internet.

Physicists discover never-before seen particle sitting on a tabletop
Researchers have discovered a new particle that is a magnetic relative of the Higgs boson. Whereas the discovery of the Higgs boson required the tremendous particle-accelerating power of the Large Hadron Collider (LHC), this never-before-seen particle — dubbed the axial Higgs boson — was found using an experiment that would fit on a small kitchen countertop.

A ‘beyond-quantum’ equivalence principle for superposition and entanglement
The physics of the microrealm involves two famous and bizarre concepts: superposition and entanglement. Both are described mathematically by quantum theory, but many physicists believe that one day quantum theory will need to be replaced by an ultimate theory of reality that lies beyond quantum theory. Now, a team of physicists and mathematicians has discovered a new connection between these two weird properties that does not assume that quantum theory is correct. Their work, partially funded by the Foundational Questions Institute, FQXi, confirms that current quantum cryptographic protocols, which promise ultra-secure un-hackable...

This particle's heft could hint at a crack in physics’ standard model
There’s something amiss with a mass. A new measurement of the mass of an elementary particle, the W boson, has defied expectations. The result hints at a possible flaw in physicists’ otherwise stalwart theory of the fundamental bits and bobs of our world, known as the standard model.

Some Scientists Say Time Might Not Exist at All
Shout out to those of you who enjoy wavering between huge ideas and finding solace in the grey spaces. Some individuals prefer absolutes (good and evil, right and wrong), while others recognise that the majority of our lives take place on a continuum. As it turns out, we are currently seeing one of the most significant such battles: the conventional model of physics vs the quantum model of physics. And, depending on how you look at it, time could not exist at all.

Ancient Namibian stone could hold key to future quantum computers

A New Tool for Finding Dark Matter Digs Up Nothing
Even the strongest gravitational waves that pass through the planet, created by the distant collisions of black holes, only stretch and compress each mile of Earth’s surface by one-thousandth the diameter of an atom. It’s hard to conceive of how small these ripples in the fabric of spacetime are, let alone detect them. But in 2016, after physicists spent decades building and fine-tuning an instrument called the Laser Interferometer Gravitational-Wave Observatory (LIGO), they got one.

Physicists Think They've Finally Cracked Stephen Hawking's Famous Black Hole Paradox
At the heart of every black hole sits a problem. As they sizzle away into nothingness over the eons, they take with them a small piece of the Universe. Which, quite frankly, just isn't in the rule book.

Scientists believe there could be an ‘anti-universe’ next to ours
A wild theory suggests there may be an "anti-universe" that runs backwards in time before the Big Bang. The concept, explained in a paper accepted for publication in the journal Annals of Physics, suggests that the reason for this universe is because there are fundamental symmetries in nature – such as charge, parity, and time. This fundamental symmetry is known as CPT symmetry.

What happened before the Big Bang?
In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Or at least, that's what we've been told by physicists for the past several decades.

Earth's core is neither solid iron, nor liquid. It's a whole lot weirder
We've known for a while that Earth's deepest depths, its "solid iron" inner core, isn't made of pure iron — and now scientists say it might not be solid either.
