In the realm of physics, the speed of light is considered one of the most fundamental constants in the universe, dictating ...

For the first time, researchers have seen how light behaves during a mysterious phenomenon called 'imaginary time'.

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

Minimizing crosstalk between imaging regions leverages the sensitivity and spectral range of single-photon imaging with the ...

A paper questions assumptions about ‘nonlocality,’ the instantaneous influence between particles at a distance, rekindling old questions about freedom of choice ...

Physicists tested the Greenberger–Horne–Zeilinger (GHZ) paradox, which is at the heart of quantum theory, to measure light ...

The idea of a particle that races faster than light has long fascinated physicists. Known as the tachyon, it was originally ...

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

But axions were pushed aside as the WIMPs hypothesis gained more steam. Back-of-the-envelope calculations showed that the ...

The system consists of only a single millimeter-scale photonic chip without any moving parts.

Tesla has begun its first paid Robotaxi service in Austin, Texas, using driverless Model Y vehicles monitored by human safety staff. But questions remain over safety, transparency and regulation ...

The satellite operates 22,807 miles above Earth, while Starlink satellites are at around 341 miles This kind of speed could ...
