Can man travel at the speed of light?

Answer 1

Nothing in this universe travels with the speed greater than or equal to the speed of light.According to the special theory of relativity, if an object is traveling with the speed of light, length contraction of that object takes place. The length of the object in the direction of the motion will contract, whereas the length perpendicular to the motion will remain unaffected.

But just for arguments sake, if you did travel at the speed of light the only thing that we know that will happen will you will lose your sight (while travailing at the speed of light) because the light will not have anouth time to reach your eye but you may see flashes and blips such as the ones in Science Fiction, this is just due to the luck of light actual hitting your eye.

Answer 2

there is an explanatory example made by one of the greatest theoretical physicists named Mostafa Mosharafa, he said that if there is a clock and the time was 12 am then u left the clock traveling with the speed of light , now when the clock points at 12 and one second the light will reflect from the clock to you so you can see it, but the light won't reach to you since you are traveling with the same speed ( the light speed) and you commenced your journey earlier i.e the light will never catch you.apply this to e+very thing ; when you travel with the speed of light every thing will seem unchanging the picture will never change, and since time is change time will stop.

Answer 3

There has been some discussion among scientists that perhaps some of the constants of nature are changing. One of these is the so-called fine structure constant, which currently has a nice dimensionless value of about 1/137.

The problem with your question is that it is not possible to show that the speed of light is slowing down. You see, the speed of light has the dimensions of meters per second. Now these are of course defined quantities by humans, and we actually use the speed of light in our definition of a meter, so any slowing down of the speed of light would remain undetected since our notion of a meter also changes!

Defining the meter as anything else, like some kind of gold encrusted ruler stored somewhere is likewise dangerous, because we would never be able to distinguish a change in the speed of light from a subtle change in the ruler's length due to, say, quantum fluctuations.

You can only really talk about dimensionless quantities like the fine structure constant since these do not depend on human conventions at all (because they are dimensionless). Of course the fine structure constant can be expressed in other quantities such as Planck's constant and the speed of light, but then it is not really clear whether it is the speed of light that is changing or Planck's constant.

Answer 4

It is impossible for anything except photons to move at the speed of light, but if humans could, science predicts that several things would happen. 1. Time would move infinitely slowly for you, possibly even stop. 2. You would weigh an infinite amount. 3. You, or more accurately, the space you occupy, would contact to an infinite amount, possibly making you non-existent.

Answer 5

The faster you move, the slower your clocks run. You don't notice anything,

but if anybody else is watching you, they can see that your watch is running

slow and your heart is beating slower.

If you reached light speed, this effect would go all the way. That doesn't mean

that your watch and your heart would stop. Again, you wouldn't notice anything,

but if anybody else were watching you, they would see that the time between

ticks of your watch and beats of your heart became infinite.

You would have other, more serious problems, however, since your mass would be

infinite, your thickness would be zero, and you would have depleted all the energy

in the universe to push yourself to light speed.

By the way . . . you don't have to go all the way to light speed to see this happen.

You just have to make something move. When a very accurate clock, like a laboratory

cesium beam clock, is put on an airplane and flown around for a while, it comes

back with some time lost . . . it 'ticked' slower while it was in flight.

Answer 6

The faster a clock travels, the slower it appears to run.

Answer 7

If a person were to travel at the speed of light, their kinetic energy, and thus their mass, would be inifinite.

Answer 8

short answer: yes

Answer 9

No.
