A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have formed ...

The Big Bang is often described as the explosive birth of the Universe – a singular moment when space, time and matter sprang into existence.

For identical quantum particles, there is neither an analogous quantity that could be measured nor a more perfect measuring device that could discern some other difference between them. Quantum ...

Lo Franco and Compagno also found that identical particles will always be at least as entangled as non-identical ones placed in the same quantum state. “This suggests that identical particles may be ...

The idea centers around the Pauli exclusion principle, which is a well-known quantum rule that prevents identical particles from occupying the same space. Gaztanaga believes this principle prevents ...

Nuclear physicists have found a new way to see inside nuclei by tracking interactions between particles of light and gluons. The method relies on harnessing a new type of quantum interference ...

Particles in our regular 3-D world can’t do this magic trick. ... All fundamental subatomic particles fall into two classes, based on how identical particles of each type behave when swapped.

It's all down to a rule called the quantum exclusion principle, which states that no two identical particles known as fermions can occupy the same quantum state (such as angular momentum, or "spin").
