What particles go faster than light?
An Italian experiment has unveiled evidence that fundamental particles known as neutrinos can travel faster than light.
What is a ghost particle?
In the terminology of quantum field theory, a ghost, ghost field, ghost particle, or gauge ghost is an unphysical state in a gauge theory. Ghosts are necessary to keep gauge invariance in theories where the local fields exceed a number of physical degrees of freedom.

What is faster than the speed of light?
Albert Einstein’s special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299,792 km/s.
What is faster than light in the universe?
The Big Bang itself expanded much faster than the speed of light. But this only means that “nothing can go faster than light.” Since nothing is just empty space or vacuum, it can expand faster than light speed since no material object is breaking the light barrier.
Is tachyon real?
Tachyons have never been found in experiments as real particles traveling through the vacuum, but we predict theoretically that tachyon-like objects exist as faster-than-light ‘quasiparticles’ moving through laser-like media.
What is the God Particle in dark?
Sometimes referred to as the “God particle,” the Higgs boson is unique in that physicists believe it to be responsible for giving other particles their mass. “This is one of the last missing pieces of the theoretical understanding we have of particle physics,” says Willocq.
