From forming bound states to normal scattering, many possibilities abound for matter-antimatter interactions. So why do they annihilate?

There may be unknown particles lurking inside the quantum foam.

Is it like a tiny ball — or what?

It’s not about particle-antiparticle pairs falling into or escaping from a black hole. A deeper explanation alters our view of reality.

Some processes, like quantum tunneling, have been shown to occur instantaneously. But the ultimate cosmic speed limit remains unavoidable.

Everything acts like a wave while it propagates, but behaves like a particle whenever it interacts. The origins of this duality go way back.

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?

Quantum physics is starting to show up in unexpected places. Indeed, it is at work in animals, plants, and our own bodies. 

The Multiverse fuels some of the 21st century’s best fiction stories. But its supporting pillars are on extremely stable scientific footing.

Perhaps the whole Universe is the result of a vacuum fluctuation, originating from what we could call quantum nothingness. 

All matter particles can act as waves, and massless light waves show particle-like behavior. Can gravitational waves also be particle-like?

It’s 2024, and we still only know of the fundamental particles of the Standard Model: nothing more. But these 8 unanswered questions remain.

Discrepancies between observations and theory regarding subatomic particles called muons may force scientists to rethink the quantum world.

You will need determination, humility, and courage if you are to master anything.

When cosmic inflation came to an end, the hot Big Bang ensued as a result. If our cosmic vacuum state decays, could it all happen again?

The ANITA experiment found cosmic rays shooting out of Antarctica. One interpretation claims “parallel Universes,” but is that right?

The matter that creates black holes won’t be what comes out when they evaporate. Will the black hole information paradox ever be solved?

Matt Strassler’s journey into fundamental physics culminates in a brilliant explanation of the Higgs field. Enjoy this exclusive interview.

Humans, when we consider space travel, recognize the need for gravity. Without our planet, is artificial or antigravity even possible?

When it comes to predicting the energy of empty space, the two leading theories disagree by a factor of 100 googol quintillion.

When black holes disappear, what happens to the stuff that fell in? Physicist Brian Cox explains.

Quantum uncertainty and wave-particle duality are big features of quantum physics. But without Pauli’s rule, our Universe wouldn’t exist.

Glueballs are an unusual, unconfirmed Standard Model prediction, suggesting bound states of gluons alone exist. We just found our first one.

Even with quantum teleportation and the existence of entangled quantum states, faster-than-light communication still remains impossible.

If nature were perfectly deterministic, atoms would almost instantly all collapse. Here’s how Heisenberg uncertainty saves the atom.

IceCube scientists have detected high-energy tau neutrinos from deep space, suggesting that neutrino transformations occur not only in lab experiments but also over cosmic distances.

Gravity defies quantum mechanics. What does that mean for a theory of everything?

Holograms preserve all of an object’s 3D information, but on a 2D surface. Could the holographic Universe idea lead us to higher dimensions?

How are we to deal with the quantization of spacetime and gravity?

When one path is blocked, a new one must be paved. How Einstein, Heisenberg and Gödel used constraints to make life-changing discoveries:
