Nobel Laureate and physicist Adam Riess and Brian Greene discuss the paradigm-shattering discovery that the expansion of the universe is accelerating, the role of dark energy, and more. This program …

The multiverse hypothesis, suggesting that our universe is but one of perhaps infinitely many, speaks to the very nature of reality. Join physicist Brian Greene, cosmologists Alan Guth and Andrei Linde, and philosopher Nick Bostrom as they discuss and debate this controversial implication of forefront research.

Renowned cosmologist David Spergel joins Brian Greene to discuss the triumphs and tensions of precision cosmology, exploring remarkable successes as well as persistent discrepancies bedeviling current understanding. This program is …

Dark energy is cosmology’s biggest mystery—an anti-gravitational force that confounds the conventional laws of physics. It makes up more than two-thirds of the cosmos, but science is still grappling to explain what dark energy actually is.

A compelling narrative is the true heart of science writing, whether it comes in the form of a science fiction classic like Frankenstein or a physicist’s blog posts. But what are the specific ways that writers illuminate and humanize science?

Come venture deep inside the world’s biggest physics machine, the Large Hadron Collider. This extraordinary feat of human engineering took 16 years and $10 billion to build, and just weeks ago began colliding particles at energies unseen since a fraction of a second after the big bang.
