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 […]
Since its observation discovery in the 1990s, dark energy has been one of science's biggest mysteries. Could black holes be the cause?
From the Big Bang to dark energy, knowledge of the cosmos has sped up in the past century — but big questions linger.
The answer to the age-old philosophical question of whether there is meaning in the Universe may ultimately rest upon the power of information.

Why does time move forward but not backward? Physicist Sabine Hossenfelder explains.
The solution involves the infamous Navier-Stokes equations, which are so difficult, there is a $1-million prize for solving them.
The Universe isn't as "clumpy" as we think it should be.

How the Big Bang gave us time, explained by theoretical physicist.
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.
Humanity's newest, most powerful space telescope is performing even better than predicted. The reason why is unprecedented.
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.
