Are Black Holes Really Paradoxical? An Interview with David Wallace

If black holes destroy information, they create a serious conflict within otherwise well-established theories.

Today in Quanta magazine, I have an article on recent efforts to de-paradoxize black holes. Before you dive into the details, you might wonder about the framing. How paradoxical are black holes, really? Physicists and science writers throw around the word “paradox,” but do these cosmic sinkholes pose any out-and-out contradiction? I put the question […]

Gravitational Waves Reveal the Universe before the Big Bang: An Interview with Physicist Gabriele Veneziano

The BICEP2 discovery of primordial gravitational waves was premature, but got theorists wondering about what came before the big bang.

It’s not usually put like this, but the discovery of primordial gravitational waves two weeks ago has given us our first direct glimpse of a period before the big bang. [The discovery was later retracted, but I’ll keep this post here to show why theorists at the time found it so exciting.] The term “big […]

The Wholeness of Quantum Reality: An Interview with Physicist Basil Hiley

David Bohm's longtime collaborator explains why he thinks quantum physics describes a holistic reality.

VIENNA—One night in 1952, Richard Feynman and David Bohm went bar-hopping in Belo Horizonte. Louisa Gilder reconstructs the night in her brilliant book on the history of quantum mechanics, The Age of Entanglement. Feynman was on a sabbatical in Rio and, ever exuberant, raved about local beers, drumming lessons, and Brazilian girls. Bohm, teaching at […]
