Question

Can antimatter go at the speed of light ?

Answer 1

Hint:Antimatter is a type of material made up of antiparticles. Any known particle is thought to have an antimatter counterpart that is nearly identical to it but has the opposite charge.Antimatter, on the other hand, cannot travel at the speed of light. There is no massive fundamental particle that can travel at the speed of light in the universe.

Complete answer:
Ultra high energy astrophysical neutrons, which accelerate almost at the speed of light, are the fastest known massive fundamental antimatter. Neither matter nor antimatter can travel faster than the speed of light. Since they both have positive mass and accelerate in the same way, they can't reach lightspeed.

The formulas allow for speeds greater than lightspeed mathematically, but this is irrelevant since there is no way to get there from below lightspeed. Most scientists agree that particles with that speed (such as tachyons) will split causality, so they don't exist.At lightspeed, only photons = antiphotons fly. Nothing moves faster than matter or antimatter.

I believe the initial inspiration for faster-than-light antimatter came from a \[7\]-year-old erroneous measurement of neutrino speed. It may have been caused by the neutrino's brief transformation into a faster-than-light antineutrino, according to one theory. Of instance, the calculation turned out to be inaccurate.

Note: Nature's laws aren't set in stone; they can and do change. The speed of light improved by \[20\] kilometres per second between \[{\text{1928}}\,\,{\text{and}}\,\,{\text{1945}}\]. Einstein's relativity theory still holds true, and he confirmed that nothing could possibly surpass the speed of light, but it is possible
