We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Mind = blown.

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an ...

Quantum theory has long treated time as a silent backdrop, a parameter that never jitters even as particles flicker in and ...

Scientists have created the highest resolution map of the dark matter that threads through the universe—showing its influence ...

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

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...
