If you travel twice the speed of light would you grow younger?

The speed of light is always fixed at 299792458 m/s. Forget your question. There is nothing faster than the speed of light.


Is it possible to travel at the speed of light in water?

The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.


What do you need to travel at the speed of light?

There is no way to travel at the speed of light.

Can a person travel at a speed of light?

No. Nothing with mass can travel at the speed of light.


What commercial arliner travel twice the speed of sound?

There is currently no commercial airliner which can travel at that speed.


How do you travel in the speed of light?

You don't. The only objects that can travel at the speed of light are those that ONLY travel at that speed, like photons or gravitons.


Why people don't travel at speed of light?

According to Einstein's theories we cannot travel at the speed of light, only close to it. There are many theories on how we can travel near (or beyond) the speed of light.


What electromagnetic waves travel at the speed of light?

All electromagnetic waves travel at the speed of light.


What travels at light speed besides engines?

Engines cannot travel at light speed. The only thing that can travel at this speed is the Photon, the particle of light.


Which speed faster then the speed of light?

Will light speed travel be possible in our lifetime?

Probably not in five lifetimes! Light speed travel is a work of fiction, like in sci fi movies. No human will ever travel at the speed of light.


At what speed do electromagnetic waves travel?

the speed of lightspeed of light


Can a particle without mass travel at the speed of light?

Yes, a photon may travel at the speed of light. If it had mass, at the speed of light, its mass would be infinite. This is impossible, so photons travel at the speed of light and have no mass.


Can neutrinos travel faster than the speed of light?

No. Nothing can travel faster than the speed of light.


Is it possible to travel back to the past if we travel at the speed of light?

No. By travelling FASTER than the speed of light, this might in theory let you travel back in time. However, it seems likely that neither travelling faster than the speed of light nor time travel is possible. Also note that a human being cannot travel at the speed of light; with a super-spaceship, we might in theory approach this speed, but not quite reach it. Only particles with "zero rest mass" (such as photons or gravitons) can travel at the speed of light (and, in a vacuum, they can ONLY travel at the speed of light).


Do gamma rays travel at the speed of light?

Gamma rays travel exactly the speed of light because gamma rays are light


Does electrons travel through an electrical circuit at the speed of light?

No Electron does not travel at speed of light. The speed at which the electron travels in a conductor depends on the material. However the current travels at speed of light.


X-rays travel in vacuum at a higher speed than the visible light?

No. Both travel at exactly the same speed. The speed of light.


Can you travel into future or past by travelling at speed of light?

In theory, time travel can be accomplished by traveling the speed of light. However, the theory also states that travel at that speed is not possible.


How To Travel At The Speed Of Light?

You can't travel at the speed of light. It might be possible, in theory, to approach it, but not quite to reach it.


How do you think it would be possible to travel at the speed of light?

The only way to travel at the speed of light is to not have any mass.


What can travel at speed of light?

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.


Is any thhing reach the speed of light?

Light is an electromagnetic wave and all electromagnetic waves travel at the speed of light. All massless particles travel at the speed of light too.
