Theoretical physicists like to ask big questions. How did the universe begin? What are its fundamental constituents? And what are the laws of nature that govern those constituents? If we look back ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...

You may think of physics as a way to explain the behaviors of things like black holes, colliding particles, falling apples, and quantum computers. But a small group physicists today is working on a ...

Constructor Theory is the ability to see the deepest underlying facts about the world. The people behind the greatest leaps in physics - Einstein, Newton, Heisenberg, all had the uncanny ability to ...
