A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...
This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...
A hundred years ago this week, at the height of the quantum revolution, Austrian physicist Erwin Schrödinger submitted a ...
A century ago, Erwin Schrödinger came up with an equation that says how the quantum world behaves. Now scientists are asking ...
Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold ...
A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...
Here’s what you’ll learn when you read this story: Entropy. The word itself should cause insomnia. It means that matter and energy will degrade—ultimately leading to chaos in the universe—if things ...
