Is computation the fundamental framework of reality? I'm open to the idea but not yet sold. Stephen Wolfram will make the case in our conversation.

Can we visualize higher dimensions? After 40+ years working on the math, the best I can do is imagine lower-dimensional analogs and projections, like this hypercube. Some claim to truly see higher dimensions. I’m not one of them.

With AI, authorship is blurring, it’s becoming vague—much like in ancient times when myths and sacred texts had no identifiable author. So perhaps we are circling back to stories shaped not by individuals, but by collective voice. AI may be less a leap forward than a return.

Different approaches to quantum mechanics tell radically different stories about the underlying structure of reality, so calling them different “interpretations” is misleading. Physics is more than predictions. It should provide a comprehensive narrative of nature’s workings.

What is consciousness? Many see this as the deepest mystery. My guess: One day, when digital systems claim to have inner experiences, we will just shrug and accept that consciousness accompanies sufficiently rich and robust information processing.

Space itself rushes over the edge of a black hole like a waterfall flowing at the speed of light. Since nothing can “paddle” upstream faster than light, nothing can escape this waterfall of space— which is why nothing can escape a black hole.

Is math discovered or invented? Most scientists say discovered. I used to agree. But I’ve come to think we invent systems to impose order, and math is our most powerful language for expressing that order.

A simple quantum truth that never ceases to delight: We spend our lives floating on a sea of repelling electrons. We never truly touch anything. What we call "touch" is just the sensation of our electrons pushing against the electrons in everything around us.

What people often get wrong: In quantum teleportation, it's not matter that's teleported. Instead, quantum information describing matter is teleported. Which raises the deep question: Are you the sum of your information? I think so, but would surely hesitate to find out.

99 years ago this month, Schrödinger breaks through with a version of his famous quantum equation, still central to our understanding.

Join my conversation on cosmic origins with inflationary cosmology's co-founder Andreas Albrecht:

Even though I believe mathematics is invented, not discovered, the poetry in this remark of Einstein still resonates deeply: "Equations are more important to me because politics is for the present, while an equation is for eternity." -- Albert Einstein.

Pioneer of quantum mechanics, Neils Bohr, had a powerful influence on other physicists, profoundly shaping how the subject developed. (Full program on quantum mysteries : )

My kids taking in Hope Bay, Antarctica.

We are now less than a day from Antarctica on Space2Sea adventure.

Step into the mind of extraordinary brilliance. My conversation with Benjamin Labatut takes us to the edge of human capability.

The deepest unresolved question at the heart of Quantum Mechanics: How does the nebulous, probabilistic, quantum haze transition into the definite reality of everyday experience?

Will next level AI need to incorporate models of mind/consciousness?
