Quantum mechanics + consciousness: There is nothing better than mixing two great mysteries to produce an even bigger one.

Everything is made of matter, not antimatter, including black holes. If antimatter black holes existed, what would they do?

The DUNE project will beam tiny neutrinos across vast distances. But the first step involved moving a heavier material: 1 million tons of rock.

The anthropic principle has fascinating scientific uses, where the simple fact of our existence holds deep physical lessons. Don’t abuse it!

Many still cling to the idea that we live in a deterministic Universe, despite the nature of quantum physics. Now, the “least spooky” interpretation no longer works.

Singularities frustrate our understanding. But behind every singularity in physics hides a secret door to a new understanding of the world.

Quantum physics isn’t quite magic, but it requires an entirely novel set of rules to make sense of the quantum universe.

Travel half the distance to your destination, and there’s always another half to go. Despite Zeno’s Paradox, you always arrive right on time.

Roger Babson wanted a “partial insulator, reflector, or absorber of gravity” — something, anything, that would stop or dampen it.

Is the multiverse real? It’s one of the hottest questions in all of theoretical physics. We invited two astrophysicists to join the debate.

Does it have a deeper significance — or is it just a number?

From the tiniest subatomic scales to the grandest cosmic ones, solving any of these puzzles could unlock our understanding of the Universe.

AI was key to making Moderna’s COVID mRNA vaccine. Its role in mRNA therapeutics will rapidly grow in the coming years.

Einstein hated “spooky action at a distance,” but much to his chagrin, quantum mechanics remains as spooky as ever.

From a hot, dense, uniform state in its earliest moments, our entire known Universe arose. These unavoidable steps made it all possible.

Most waves need a medium to travel through. But the way that light and gravitational waves travel shows that space can’t be a medium at all.

Scalars, vectors, and tensors come up all the time in physics. They’re more than mathematical structures. They help describe the Universe.

Magnetic monopoles began as a mere theoretical curiosity. They might hold the key to understanding so much more.

In our Universe, matter is made of particles, while antimatter is made of antiparticles. But sometimes, the physical lines get real blurry.

Is this video four minutes long? Not necessarily.

The concept of ‘relativistic mass’ has been around almost as long as relativity has. But is it a reasonable way to make sense of things?

The original principle of relativity, proposed by Galileo way back in the early 1600s, remains true in its unchanged form even today.

Researchers at the Brookhaven National Laboratory recently created the heaviest exotic antimatter hypernucleus ever observed.

For a substantial fraction of a second after the Big Bang, there was only a quark-gluon plasma. Here’s how protons and neutrons arose.

In Sun-like stars, hydrogen gets fused into helium. In the Big Bang, hydrogen fusion also makes helium. But they aren’t close to the same.

In scientific theories, the Multiverse appears as a bug rather than as a feature. We should squash it.

At very high and very low temperatures, matter takes on properties that open up an entire Universe of remarkable new possibilities.

What do we mean by a black hole’s size? A photon sphere? The minimal stable orbit? The event horizon? The singularity? Which one is right?

The expanding Universe, in many ways, is the ultimate out-of-equilibrium system. After enough time passes, will we eventually get there?

For every proton, there were over a billion others that annihilated away with an antimatter counterpart. So where did all that energy go?
