I don't even try to figure out relativity theory anymore. And if you are not confused already consider that light ACTS as if it were moving from its sourse to its destination and from its destination to its sourse - simutainously! Just let the damn stuff do what it wants.

Does anybody know what the speed of dark is? When you shut off a light darkness approaches. So I guess dark moves at the speed of light....hmm

but when its dark it is dark every where so then dark would be moving at infinite speed....I guess, ah to heck with it.

Shadow, I have a simple solution to your question.

How do you turn day into night?

Just pull the covers over your head you Soap Sucking Nincompoop! (He He!!!)

Yes! Yes! Quite so! With the proper application of Blanket Technology we could actually attain the speed of darkness!
 
RE: HELP! Why can\'t you go past the speed of Light?

Yes, but there is no physical proof that the light particals coming out of the Cesium Chamber are the same particals that entered!

Nobody seems to understand what is actually accuring in the Cesium Chamber. So the question still stands whether the speed of light was broken???

Personally I still think the blanket method works best! So blah blah blah!!!

Hi 'George',

One answer to your original question is contained in Relativity Theory:
When an object is accelerated towards light-speed, three things happen to that object as a consequence of Relativity:
1/ The object's LENGTH decreases (called the Lorentz Contraction), becoming ZERO once light-speed is attained.
2/ The object experiences Time to pass SLOWER compared to an object moving at a slower rate - This is called Time Dilation. (eg: Someone on a spaceship travelling at close to light-speed would have aged LESS than their friends back on Earth when they returned from their trip.)
3/ The MASS of the object increases, becoming INFINITE once light-speed is attained.

Physicists say that attaining light-speed is impossible for a material object because, as its mass increases toward infinity, you would need more and more energy to keep accelerating the object. Once light-speed was attained (if that were possible), the object would have infinite mass, and you would therefore need an energy value of greater than infinity (which is, as far as we know, impossible) to accelerate it any further.

I don't like that idea, because I'm a budding Time-Traveller. My arguement with that idea is that the reaction-mass on a spacecraft (ie: its fuel, the MASS of which is converted to energy in order to accelerate the spaceship) would also be increasing along with the rest of the ship, so the energy gained from the reaction-mass would be increasing toward infinity as well...
My own theory is that Time passes at the same speed as light, which is why you get the Time Dilation effect. Once light-speed was attained, you would have effectively 'caught-up' with Time. Humans can only perceive and measure things with reference to Time (ie: 'Miles per HOUR', etc), so anything travelling at the same rate as Time itself, or even faster than Time, would be outside human perception, and would APPARENTLY have ceased to exist....
 
RE: HELP! Why can\'t you go past the speed of Light?

The limiting factor in traveling at the speed of light is not relativity as some people would have you belive. The limiting factor is the inability of current rocket technology to produce the needed exhaust velocity.

Once a rocket reaches the exhaust velocity of the gases the rocket engien can no longer exert the force needed to increase the velocity of the total system.

What is needed is a system that exert a force on the rocket without regard for the velocity of the rocket. If this force is applied for a sufficient amount of time the rocket will achieve light speed.

We can determine the time needed to reach light speed for any force with the equation ( Ft = MVf - MVi ).

F = force applied (in newtons)
t = time force must be applied (in second)
M = mass of total system (in kilogram)
Vf = final velocity (in meter/second)
Vi = initial velocity (in meter/second)

By solving the equation for t = ((MVf - MVi)/F)) the time needed to achieve light speed for any force applied can be found.

Example:

The mass of an automobile is 1800 kg.
Its Vf is 15.0 m/sec.
Its Vi is 0 m/sec.
F is 1350 nt

How long must the force of 1350 nt act on the automobile to give it the velocity of Vf.

SOLUTION: using t = ((MVf - MVi)/F))

t = ((1800 kg X 15.0 m/sec) - (1800 kg X 0 m/sec))/1350 nt
t = 20.0 seconds

Note: mass = weight/accelaration due to gravitational attraction.
mass is (in kilogram).
weight is (in newtons).
g is (in meter/second) 9.80 m/sec
