For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether Albert Einstein or Niels Bohr had the better grasp of the quantum world. Now a ...

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a striking concept in a 1935 paper. In that work, they described an abstract ...

A new study links the universe’s expansion to quantum topology, suggesting that hidden mathematical structures may stabilize the cosmological constant in ways previously unrecognized.

The cosmological constant has been a problem in physics since Einstein, but new research may show why it takes the value that ...

From Einstein’s spacetime to quantum entanglement, real physics offers more than mind-bending theories—it’s a goldmine for storytelling. Writers are weaving these concepts into worlds where scientific ...

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

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 ...
