Quantum mechanics is the law of likelihoods, not the script of events. Probabilities are set in stone; outcomes are improvised

Strands of a spider web--amazing electron microscope image (by Dr Martín Ramírez). Hidden wonders.

What Einstein called "spooky action"--quantum entanglement--arises from the mathematical fact that you can add quantum solutions together. Basic math; profound physics.

Tachyons—hypothetical faster-than-light particles—run on opposite rules: losing energy makes them go faster. They can never slow to light-speed.

It’s fine to thank God when an MRI, PET scan, or X-ray saves your life, but the thanks truly goes to physics—fundamental research that transformed how we probe matter. Cut funding and you cut tomorrow’s lifesaving breakthroughs.

My son Alec Day Greene in Annie Baker’s “Circle Mirror Transformation” at Oxford University.

I was drawn to mathematics because its truths seemed eternal. I've focused on physics because its truths speak to reality.

Cross a black hole’s edge and space and time swap roles, so you're drawn to the center as inexorably as tomorrow follows today.

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. youtube.com/watch?v=yAJTct…

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.
