A ball tossed into the air follows a path that classical physics can track with confidence. Shrink that ball down to the size ...

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity.

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it ...

Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely ...

Over the last few years, optical atomic clocks have broken record after record in precision timekeeping. Atoms are cooled to ...

In quantum mechanics, particles do not behave like everyday objects. Instead of existing in one clearly defined state, they ...

Researchers have developed a way to flip time to move backward in a quantum system. This level of control could lead to ...

For many of us, advanced physics can be tough to understand to begin with, which makes it all the more impressive whenever someone earns a Nobel Prize for advancing the field even further. The latest ...

Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The ...

The many worlds interpretation (MWI) of quantum mechanics, proposed by Hugh Everett in 1957, posits that reality consists of ...
