Jim Al-Khalili introduces the technologies emerging from the second quantum revolution.

Theoretical physicist Jim Al-Khalili explores why our sense of time may be incredibly misleading, including the idea that past, present, and future might all exist at once.

“The messy reality of it is that all of these very smart people, including Isaac Newton, were talking to other people.”

"Could black holes be the key to a quantum theory of gravity, a deeper theory of how reality, of how space and time works? Well, I think so."

“I like to say that physics is hard because physics is easy, by which I mean we actually think about physics as students.”

“An equation, perhaps no more than one inch long, that would allow us to, quote, 'Read the mind of God.'”

“Could black holes be the key to a quantum theory of gravity, a deeper theory of how reality, of how space and time works?”

"It's a very, very beautiful calculation, but it's the best example I know of the relationship between these rather abstract quantities perhaps and something that you can look at in a telescope."

“When you think about this interconnection of all these tiny causes and effects which add up to the way the world unfolds, it becomes impossible to imagine that we have complete control.”

“We don't have enough knowledge to precisely calculate what is going to happen, and so we assign probabilities to it, which reflects our ignorance of the situation.”

"We are all in orbit around the center of the Milky Way galaxy. How big is this collection of stars? Somewhere between 200 and 400 billion suns in the Milky Way galaxy, about 100,000 light years across."

"Quantum mechanics and quantum entanglement are becoming very real. We're beginning to be able to access this tremendously complicated configuration space to do useful things."

“You’re not meant to understand what I just said, because I don’t understand what I just said…” Physicist Brian Cox on one of the most complex theories in space science.

Is information intrinsic in our universe? NASA’s Michelle Thaller explains.

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

Consciousness isn’t just a problem for philosophers. On this episode of Dispatches, Kmele sat down with scientists, a mathematician, a spiritual leader, and an entrepreneur, all trying to get to the heart of “the feeling of life itself.”

Our host Kmele went inside Fermilab, America’s premiere particle accelerator facility, to find out how the smallest particles in the universe can teach us about its biggest mysteries.

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

Quantum wormholes are mathematically possible — but might also be physically impossible. Physicist Janna Levin explains Hawking’s famous information paradox.

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

Theoretical physics professor Michio Kaku outlines the evolution of computers from analog to digital and introduces quantum computers as the next frontier.

Sabine Hossenfelder talks about Albert Einstein, dead grandmothers, the physics of aging, and more in this full interview with Big Think.

Sabine Hossenfelder discusses the physics of… dead grandmothers?

Is science close to explaining everything about our Universe? Physicist Sabine Hossenfelder reacts.

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 […]

Everything you ever wanted to know about the Universe, explained by physicist Sean Carroll.

What do physicists actually mean when they talk about the multiverse?

Are physicists about to decode a mysterious field of science that could have huge implications for your health?

Is this video four minutes long? Not necessarily.

Our world would be impossible without quantum mechanics — but we still don’t have a narrative of how it works.
