No, antimatter cannot go at a speed of light. There is no massive fundamental particle in the universe that can go at the speed of light. Nothing can travel faster than the speed of light in a vacuum. Light always travels at the same speed in a vacuum in the form of a straight line and this constant speed is
c = 2.99792458 × 108 m s-1
- The fastest known massive fundamental antimatter is ultra-high energy astrophysical neutrions which travel almost at the speed of light.
- Antimatter is characterized as matter made up of the antiparticles of the corresponding particles of ordinary matter in modern physics.
- The opposite of matter is antimatter. Antimatter subatomic particles, in particular, have properties that are diametrically opposed to those of normal matter.
