A person cannot travel the speed of light because a propellant to move a space ship in the vacuum of space would have to travel faster than light speed. Since everything is relative, nothing travels faster than light speed (speed C).
If light, for example, was to power a space ship by pushing on giant panels it would still not be able to push the space ship fast enough to travel at light speed.
If the energy was in light, enough to push a spaceship to almost light speed, it would still not have enough energy to push the space ship to light speed. It would still be slower.
Think of light speed like this: If you wer an ant walking as fast as you could and we make this the speed of a jet liner, light speed would still be the speed of the Earth going around the sun. The speed of light is vastly faster than any machine ever made.

5 kilograms is a mass that weighs roughly 11 pounds on earth; so our object is
something roughly like a Bowling ball ... you can pick it up, hold it, toss it, etc.
If you push on it, then it accelerates. It keeps accelerating as long as you keep
pushing.
Let's say we push on it with a ton of force ... 2,000 pounds ... and keep pushing.
It accelerates at the rate of 181 G's, and reaches 10% the speed of light in about
4.7 hours.
Notice that 181 G's is pretty ridiculous, because it would shatter anything constructed
from known materials.
Let's accelerate it a more reasonable rate .. say 10 G's. Still more than a human being
could tolerate and survive for very long, but it ought to be OK for a bowling ball.
In order to accelerate 5 kilograms at 10 G's, we only have to push on it with a force of
about 490 newtons ... about 110 pounds.
From a standing start, it goes from zero to 60 mph in the first quarter of a second, and
it hits 10% of the speed of light in 3.54 days, or about 85 hours.
The whole problem is: How much rocket fuel you need to keep up that much force for
that long a time.
When the 5 kilograms reaches 10% of the speed of light, its kinetic energy is 2.25 x 1015 joules.
That's 625 million kilowatt hours.
According to some numbers I found online from the "California Statewide Residential Appliance
Saturation Study of 2004", this is the amount of electrical energy used by 104,000 average
3-person families in California in one year!
And we needed that much energy to push a bowling ball to 10% of light speed.
The problem should be starting to come clear by now . . . .

∙ 16y agonope, forward. or rather you will age slower then the rest of us and will feel as if you went forward in time.

∙ 14y agoNo mass can be accelerated to the speed of light. Einstein showed this in his earliest papers, and we have not thought our way around restrictions that he showed were in place in nature.

Does light speed accelerate or is it instantaneous velocity?
Instantaneous.
How meany pounds of force to get light speed?
It takes an infinite amount of energy to accelerate an object with mass to the speed of light. It is therefore impossible.
How many g's is the speed of light?
speed of light is constant velocity and does not accelerate so there is no g force
What voltage is needed to accelerate electrons to 1.5 times the speed of light in a CRT?
It is not possible to accelerate electrons--or anything else--to the speed of light, much less to 1.5 times the speed of light. Nominal operating voltages for a CRT range from a couple of thousand volts to a few tens of thousands of volts, depending on the application.
Will the mass change at a very high speed compared the speed of light?
Yes. According to the extended theory of relativity, mass will increase as an objects speed increases. The closer the object's speed gets to the speed of light, the greater its mass will be and a greater force will be required to continue to accelerate it.
Does light speed accelerate or is it instantaneous velocity?
Instantaneous.
Does light accelerate?
No. As long as it stays in the same material, its speed is constant.
How meany pounds of force to get light speed?
It takes an infinite amount of energy to accelerate an object with mass to the speed of light. It is therefore impossible.
How many g's is the speed of light?
speed of light is constant velocity and does not accelerate so there is no g force
Does light create its own mass?
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.
Around what year will you accomplish traveling at the speed of light?
I will never manage.If someone else manages to accelerate something tangible to the speed of light it will be far in the future.
What voltage is needed to accelerate electrons to 1.5 times the speed of light in a CRT?
It is not possible to accelerate electrons--or anything else--to the speed of light, much less to 1.5 times the speed of light. Nominal operating voltages for a CRT range from a couple of thousand volts to a few tens of thousands of volts, depending on the application.
Can an object gain the velocity of light?
The word object is a very general term. A photon is also an object, and it does travel at the speed of light. But it never travels at any other speed, so it doesn't "gain" that speed. If we were to ask about objects made of atoms, then the answer is no, they can never accelerate to the velocity of light. They can get arbitrarily close, depending upon how much energy is used to accelerate them, but they can never actually get to the full speed of light.
Can mass of an electron be doubled?
Yes, if you accelerate it to the correct percentage of the speed of light its mass will be doubled.
How would the speed of an object be affected if it were in a vacuum?
Assuming you keep applying a constant force, it will accelerate indefinitely up to the speed of light
What is a sentence for the word accelerate?
He would wildly accelerate his car when the traffic light turned green. Gravity causes falling objects to accelerate as they move toward the Earth. Living in a foreign country can accelerate the speed at which you learn the native language.
Can you theoretically go faster than light?
No, you can't go faster than the speed of light. This is because you would need an infinite amount of force to accelerate an object to a velocity faster than the speed of light.
