53 - Why We Need a Theory of Quantum Gravity

An unlikely change in the theory of quantum mechanics would lead to bizarre new conclusions. Our guest talks us through non-linear quantum mechanics, and how physicists like him are testing it.For ad-free episodes and exclusive ask-us-anything segments, join us for just $3 a mont ...  Show more

Quantum mechanics is full of surprises. But somehow, the theory is captured almost entirely in a single equation. Today we explore the Schrödinger equation: how it works, what it says about nature, and why it revolutionized physics.For ad-free episodes and exclusive ask-us-anythi ...  Show more

Melvyn Bragg examines 20th century physics’ quest for the ultimate theory of everything. Einstein left us with his theory of General Relativity, which explained how gravity works on the scale of stars, galaxies, and the universe itself and Schroedinger left us with the equation t ...  Show more

The quest for a theory of everything – explaining all the forces and particles in the universe – is arguably the holy grail of physics. While each of our main theories of physics works extraordinarily well, they also clash with each other. But do we really need a theory of everyt ...  Show more

Melvyn Bragg examines Quantum Gravity. Early in the 20th century physicists were startled by the realisation that the smallest things in the universe do not obey Newton’s laws of gravity. Ripe apples fall from trees, billiard balls roll mostly on the table and the moon orbits the ...  Show more

Synthesizing relativity and quantum theory would be the crowning achievement of science, a profound merging of all the forces of nature into one beautiful, magnificent equation to unlock the deepest mysteries in science. In this episode, Michael Shermer speaks with professor of t ...  Show more
