It's easy to forget that long standing scientific theories are in fact, theories and therefore are subject to revision and change as new information comes to light or we develop new ways to understand our Universe. The current accepted theory on the creation of our Universe is, o ... Show More

A century ago, astronomers were locked in a debate about the scope of our universe. Were we it? The answer is no. There are other galaxies beyond the Milky Way, and they are speeding away from us. Answering that question left astronomers with an even bigger puzzle. Why is everyth ... Show More

<p>Quantum mechanics and general relativity are two of the most successful theories of science ever, but they don&apos;t necessarily fit together. Learn why physicists are trying so hard to discover a quantum theory of gravity, and why it&apos;s been such a challenge.<br/><br/>Fo ... Show More

Are you ready to uncover the mind-bending secrets of our universe? Join us as we reveal the unexpected truth about the formation of habitable planets and the potential for multiple habitable worlds within a single solar system. You won't believe how many habitable planets could e ... Show More

<p>Last time, we introduced the biggest open problem in theoretical physics - the problem of combining gravity with quantum mechanics. In this first part of a three-part series, we introduce the leading candidate for how to do that: String Theory.<br/><br/>For ad-free episodes an ... Show More
