Frank Wilczek is celebrated for his investigations into the fundamental laws of nature that have transformed our understanding of the forces that govern our Universe. In this video, the MIT […]
When you combine the Uncertainty Principle with Einstein's famous equation, you get a mind-blowing result: Particles can come from nothing.
Recent measurements of subatomic particles don't match predictions stemming from the Standard Model.
Though quantum mechanics is an incredibly successful theory, nobody knows what it means. Scientists now must confront its philosophical implications.
Experiments tell us quantum entanglement defies space and time.
When you bring two fingers together, you can feel them "touch" each other. But are your atoms really touching, and if so, how?
To Einstein, nature had to be rational. But quantum physics showed us that there was not always a way to make it so.
Einstein tried to disprove quantum mechanics. Instead, a weird concept called entanglement showed that Einstein was wrong.
"Once quantum mechanics is applied to the entire cosmos, it uncovers a three-thousand-year-old idea."
It isn't just identical particles that can be entangled, but even those with fundamentally different properties interfere with each other.
Quantum superposition challenges our notions of what is real.
The difference between predictions and observations of the magnetic properties of muons suggests a mystery for the Standard Model.
The quantum world — and its inherent uncertainty — defies our ability to describe it in words.
For nearly a century, physicists have argued over how to interpret quantum physics. But reality exists independent of any interpretation.
For years and over three separate experiments, "lepton universality" appeared to violate the Standard Model. LHCb at last proved otherwise.

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.

What do physicists actually mean when they talk about the multiverse?
Perhaps wormholes will no longer be relegated to the realm of science fiction.
We'll never be able to extract any information about what's inside a black hole's event horizon. Here's why a singularity is inevitable.
Every time our Universe cools below a critical threshold, we fall out of equilibrium. That's the best thing that ever happened to us.
Maybe the brain isn't "classical" after all.
There's the textbook answer, then there's the real answer.
Maybe our understanding of quantum entanglement is incomplete, or maybe there is something fundamentally unique about consciousness.
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?
Are you unhappy with how various events in your life turned out? Perhaps, in a parallel Universe, things worked out very differently.
It's literally the one and only trick that separates top-notch physicists from crackpots, dropouts, and those who can't cut the mustard.
Einstein always loses in the quantum realm.
Uncertainty is inherent to our Universe.
They say that nobody understands quantum mechanics. But thanks to these three pioneers in quantum entanglement, perhaps we do.
