Physics
The central equation of quantum mechanics, the Schrödinger equation, is different from the equations found in classical physics.
It isn't just identical particles that can be entangled, but even those with fundamentally different properties interfere with each other.
Laser-guided lightning systems could someday offer much greater protection than lightning rods.

Do humans have souls, or are we just particles? Physicist Sabine Hossenfelder explains.
Though a single measurement is not enough to definitively decide the debate, this is a major win for dark matter proponents.
Yes, dark energy is real. Yes, distant galaxies recede faster and faster as time goes on. But the expansion rate isn't accelerating at all.
The quantum world — and its inherent uncertainty — defies our ability to describe it in words.

How did complex systems emerge from chaos? Physicist Sean Carroll explains.
For years and over three separate experiments, "lepton universality" appeared to violate the Standard Model. LHCb at last proved otherwise.
It's spooky, and it's happening all around us. And inside us.

Everything you ever wanted to know about the Universe, explained by physicist Sean Carroll.
A concept known as "wave-particle duality" famously applies to light. But it also applies to all matter — including you.
Its implications go well beyond the Earth itself, affecting even the future of space travel.
Nuclear fusion has long been seen as the future of energy. As the NIF now passes the breakeven point, how close are we to our ultimate goal?
Light carries with it the secrets of reality in ways we cannot completely understand.
Like Dua Lipa, he had to create new rules.
Vanadium dioxide is a strange material that "remembers" information and when it was stored. This is akin to biological memory.
There's the textbook answer, then there's the real answer.
SpinLaunch will cleverly attempt to reach space with minimal rocket fuel. But will physics prevent a full-scale version from succeeding?
Maybe our understanding of quantum entanglement is incomplete, or maybe there is something fundamentally unique about consciousness.

Debates about the existence of free will traditionally have been fought by two competing camps: those who believe in free will and those who don’t because they believe the Universe […]
There are at least 15 different types of solid water (ice). Now, scientists believe that there might be a second type of liquid water.
Your mentors made time for you. Now, go and make time for others.
Using physics, Ross Chastain floored it during the final turn, scraping the wall and passing 5 cars to advance to the NASCAR championship.
The stars circle each other every 51 minutes, confirming a decades-old prediction.
Early relics and late-time objects give incompatible results for the expanding Universe. This independent anomaly intensifies the problem.
Practically all of the matter we see and interact with is made of atoms, which are mostly empty space. Then why is reality so... solid?
"Even with my training, I still got insights from the book’s descriptions. That’s how good Carroll is at explaining physics."
Holograms preserve all of an object's 3D information, but on a 2D surface. Could the holographic Universe idea lead us to higher dimensions?
Over the past 50 years, 27 leap seconds have been added to our time.
