No doubt it&#39;s already been said, but you can&#39;t travel faster than the speed of light. Thus rendering the first post a moot point, in effect :P

:huh:

why is this 4th gen?

could you explaine please?

As any massive object increases in velocity, it&#39;s mass (relativistic mass) also increases. The mass increases exponentially towards infinity when the object reaches the speed of light. Of course, the object can&#39;t reach the speed of light, as the force required to accelerate a body of almost infinite mass is far too high to be supplied by us. [/b][/quote]
so how do we explaine the fact that light goes at its speed of light (300,000 km/s)?

Light has no mass

If you mean "why does it only go that fast" then I don&#39;t know.

isn&#39;t there a light paticle called the photon ? doesnt it travel at the speed of light ? is it infinite in size ? can you turn out the light before you leave ? anyway i thought the new theory was that the speed of light was not a universal constant any more.

You&#39;re making too much sense :unsure:

Hes sharing his sense openly so that others can sleep nicely and think of his treasures.

photons are considered both particles and waves, they are considered as particles for the purpose of calculations.

One should reconsider that Einstein didnt say directly that nothing can travel faster than the speed of light. All he conveyed was like 4thgen said the mass of the body will increase drastically and its not possible as of now, to provide the force.

"However the concept of spaceships, As a ship nears the speed of light it will become noticeably more massive but so will the fuel. That means that as the ship is becoming more massive the thrust is becoming higher too, since the
exhaust is more massive (heavier particles due to denser mass from
the energy to mass conversion."

Photons can be made to travel slower than the speed of light when changes are done in the environment i.e the medium it is travelling in. Basically, if anything travels faster than the speed of light it will emit Cerenkov Radiation.

Btw, beyond the light barrier exists particles called tachyons. So particles have already crossed light-barrier implying particles can do that. We juts dont have enough external force to make it happen to our objects yet.

What i want to know is if you were travelling at the speed of light in your car and you turned your headlights on what would happen. :blink:

Good question&#33;


All I can think of is, wear your sunglasses :lol: :lol:

J/k very interesting question.

One speculation: If you are travelling faster than the speed of light then by the time the light will reach you, you will already be beyong that point. Also, the light from the headlight lamps wont be falling ahead on something but rather will be staying at their position and you can see them moving slowly backwards. You will obviously be much beyond it. I guess the only way to navigate would be to use radar. Your eyes wont help you here :D

Did`nt someone also do an experiment with photons which could have destoyed the world but they went ahead a did it anyway or was that particle accelerator.???
