Quantum field theory (QFT) is the basis of the Standard Model of particle physics. This video explains what QFT is, why it’s necessary, and how it differs from non-relativistic quantum mechanics.

Empty space, despite how we think of it, may not be as empty as we assume. Although we cannot detect the virtual particles present in empty space, their presence is necessary to predict, ...

Add Yahoo as a preferred source to see more of our stories on Google. US physicists have shed light on a long-standing mystery after they captured rare experimental evidence that links the fleeting ...

The gravitational fields of black holes and other compact objects are strong enough that they might wrest massless particles out of the vacuum and into existence, causing the objects to decay. The ...

Going to smaller and smaller distance scales reveals more fundamental views of nature, which means if we can understand and describe the smallest scales, we can build our way to an understanding of ...

Physicists have proved that a subatomic particle can switch into its antiparticle alter-ego and back again, in a new discovery revealed today. The extraordinarily precise measurement was made by UK ...

Physicists working with the LHCb experiment at CERN have proven that a subatomic particle can switch into its antiparticle and back again. The researchers were able to prove this using extremely ...

US physicists have shed light on a long-standing mystery after they captured rare experimental evidence that links the fleeting virtual “nothingness” of the quantum world to the formation of real, ...
