It is not possible for any object with any mass to travel at the speed of light. It is possible to travel at 99.9999999999999999999999999999999999999% the speed of light, you could even travel at "99.9 followed by a trillion trillion 9s"% of the speed of light but never quite 100%.
According to our current mathematical theories, for an object with any mass to travel at the speed of light it would take infinite energy to attain that speed.

∙ 13y agoThe basic formula for speed still applies: distance = speed x time. Solving for time: time = distance / speed.
If the distance is expressed in light-years, it is especially easy: it takes light one year to travel one light-year.

Which waves travel the fastest?
The light wave, which is electromagnetic energy, is the fastest wave. The speed of light, which is a physics constant, is the speed of light in a vacuum, and no object with mass can be accelerated to this speed.
What do you need to travel at the speed of light?
There is no way to travel at 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.
Are there different dimensions in space and can you travel at the speed of light?
Yes, it is theorized that there are higher dimensions then the four we are familiar with. No, you cannot travel at the speed of light, no physical object that has mass can. However, that being said, you can, theoretically travel infinitely close to the speed of light which would, in turn, require an infinite amount of energy.
How much energy does it take a spaceship to travel at constant speed 90 percent of light speed?
It depends on the mass of the starship in question.
At what speed does all electromagnetic energy travel?
Electromagnetic energy travels at c, the speed of light. The speed of light, c, is 299,729,458m/s
How fast does EM energy travel?
Speed of light.
What is the percentage of the speed of light needed to time travel?
99.995 %
At what speed can matter travel?
Matter can travel at any speed you like, if you can pump enough energy into it.The only limit is the speed of light. If you can supply it with enough energy, thenyou can make the matter move as close to the speed of light as you want it to,but there is not enough energy anywhere to make it move at the speed of light.
Tell why sound which is a form of energy like light cannot travel at the speed of light?
Quite simply, the two things - being "a form of energy" and travelling at a speed of light - are completely unrelated. There are other forms of energy that don't travel at all, like potential energy.
Is it possibie to travel at the speed of light?
Nothing with a rest mass can travel at exactly the speed of light, it would take an infinite amount of energy. Light can travel at that speed because it has zero rest mass. Earlier Answer below So far, we don't know if a human can travel at lightspeed. However, it's easier to travel at the speed of light than to travel through time. New Answer: The problem I always had with the term light speed is that speed is relative. We may be traveling close to the speed of light right now in relation to some other object in the universe.
How come the theory of relativity is based on the hypothesis that matter can travel at the speed of light even though its never been accomplished?
Actually Einstein postulated that nothing can travel at the speed of light. He theorized that as something approaches the speed of light its mass increases. This means that for something to travel at the speed of light it needs to have an infinite source of energy. The only things that can travel at the speed of light are particles that have no mass, otherwise known as photons.
What is the difference between speed and light?
Speed is how fast something moves. Light is a form of energy carried by massless photons, these photons move at the speed of light, which is the fastest speed that anything in the universe can travel.
Which waves travel the fastest?
The light wave, which is electromagnetic energy, is the fastest wave. The speed of light, which is a physics constant, is the speed of light in a vacuum, and no object with mass can be accelerated to this speed.
What would happen if a car could travel at the speed of light?
It would turn to energy
What do you need to travel at the speed of light?
There is no way to travel at the speed of light.
How do you travel as fast as the speed of light?
you do not; it would take way too much energy to do this because your mass is so great. Small subatomic particles can be accelerated to close to he speed of light and they require a lot of energy from a particle accelerator. Nothing can reach the speed of light as it would take an infinite amount of energy
