Neither, mass can never reach the speed of light, this question also contridicts the theory of realativity.
No. Nothing with mass can travel at the speed of light.
The only way to travel at the speed of light is to not have any mass.
Because light has no mass.
The only thing that travels at the speed of light, is light. Light is also said to have no mass, therefore the only way for something to travel at the speed of light is for it to have no mass.
Any massless "thing" like a photon and MAYBE a neutrino. NOTHING with mass can travel at the speed of light. Photons travel at the speed of light. The entire electromagnetic spectrum travels at the speed of light.
A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.
Not many things have no mass however Photons (Light Particles) have no mass and therefore they travel at the speed of light.
A photon. Neutrinos have mass and therefore must travel at less than the speed of light. Photons of light travel at the speed of light.
Not if they have any mass, they don't.
No, nothing can.
Light travels at the maximum speed in vacuum, which is found to be 299 729 458 meters per second. Velocity of light is a constant and it cannot be altered. Nothing in the universe can travel greater than that of light. He means nothing with mass can travel faster than the speed of light. If a particle were to have no mass or negative mass it would be able to travel greater than then the speed of light. But seeing as the only thing i can think of that has no mass is thought. Although i have read the publications of some scientists that are trying to prove that though has mass. The only place things will be able to travel faster then the speed of light will be in our minds, literally.
Light does not have mass. Remember, as an object's speed approaches the speed of light, its mass approaches infinity, therefore it will require infinite energy to accelerate something to the speed of light, therefore only massless particles can travel at light speed.
