For generations, physicists have been searching for a quantum theory of gravity. But what if gravity isn’t actually quantum at all?
In general relativity, matter and energy curve spacetime, which we experience as gravity. Why can’t there be an “antigravity” force?
Two new studies examine ways we could engineer human wormhole travel.
In some Asian countries, what’s in your blood may influence your social status.
We’ll never be able to extract any information about what’s inside a black hole’s event horizon. Here’s why a singularity is inevitable.

The ANITA experiment found cosmic rays shooting out of Antarctica. One interpretation claims “parallel Universes,” but is that right?
MIT scientists show how fast algorithms are improving across a broad range of examples, demonstrating their critical importance in advancing computing.
Dark matter hasn’t been directly detected, but some form of invisible matter is clearly gravitating. Could the graviton hold the answer?
A new book envisions an encounter of minds between the Argentinian writer Jorge Luis Borges, the physicist Werner Heisenberg, and the philosopher Immanuel Kant.
Life arose on Earth very early on. After a few billion years, here we are: intelligent and technologically advanced. Where’s everyone else?
