Foe example-if some one was to switch on a torch for .1 of a second and switch it of again,and we could watch that beam of light travel through space,we would see a beam of light that was X mile's long-has a start and end-->it wouldnt be an infinite beam of light.


Ah, Tinman, not to bring Einstein into this but, what that short burst of light would look like would be dependent on your (the observer) position/velocity relative to that burst of light.

My 2 cents,

Bill

We observe in experiments that accelerating even very light particles to high fractions of C takes tremendous energy.  We observe that it takes exponentially more energy the closer to C that we get i
Note that all these experiments use EM forces to accelerate these particles.

Do you know of any experimental evidence that there is a finite upper limit on the kinetic energy of a mass at light speed or beyond?
Do you know of any experimental evidence that there is not a finite upper limit on the kinetic energy of a mass at light speed or beyond. Keeping in mind that unless some one has managed light speed,then no such evidence in either direction exist. All is theory until proven to be fact.

Indeed it would. But as we are traveling through space at a very high speed,our point of observation would be continually changing.

Yes, all the measurements of the energy required to accelerate particles to high fractions of c show exponentially greater energy as one approaches c.  No drop off in that exponential climb has shown up.

A simple electric motor draws far more power than it dose once it reaches running speed. Whats to say the same dosnt happen at light speed. Accelerating particals with an external energy source is far different to that where the energy source travels with the partical.

Quote: Faster-than-light (also superluminal or FTL) communication and travel refer to the propagation of information or matter faster than the speed of light. Under the special theory of relativity, a particle (that has rest mass) with subluminal velocity needs infinite energy to accelerate to the speed of light, although special relativity does not forbid the existence of particles that travel faster than light at all times (tachyons).

There are no experiments I know of at relativistic velocities that do anything but conform to: Kinetic Energy = mREST*c2*(1/((1-v2/c2)0.5) - 1).

You guys are way off topic.... and a lil ignorant  :P Besides, I have no doubt about Tinman being able to travel FTL, considering the proven fact that he can harvest energy that is yet to be generated in the near future, as seen in vid 1 ... BTW. How's that going, any updates?

Hi Dieter.
I got a little side tracked with this buoyancy thing,and have to show some others a little experiment i did today. i will get back to that one ASAP,but my free time is in very short supply these day's. I need to rewind the coils with a finer wire,and make sure the coupling between the two cores is exact-no air gap's. I also need to wind a couple of extra coils on the core,so as i can see when the magnetic field is passing through each coil.

...all the measurements of the electromagnetic energy required to accelerate charged particles to high fractions of c show exponentially smaller acceleration as one approaches c.

When the acceleration of charged particles decreases with speed there are two possible explanations according to Newton's 2nd law:
a = F/m

1) Mass increases with speed
2) Force decreases with speed

Einstein picked #1

That is all true.  However, from a standpoint of what obstacles make light speed or FTL travel challenging we don't have to resolve whether it is one, the other or both.  In any case the energy required to accelerate climbs exponentially without any indication of an upper limit.

What about photons?

When I turn on my flashlight, I am accelerating a large number of photons from 0 to light speed almost instantaneously.

In college we learned that photons have "mass" as proved by some university experiments in the 70's.  (I do not recall which one)

So, my question is, when these photons reach light speed, what happens/happened to their mass?  If they indeed have mass, then how did they reach the speed of light in the first place?  Was there a transformation of some kind?

I still believe in Einstein, I am sure it is my understanding that is at fault here but...after reading the previous posts, this thought just occurred to me.

So, how do this happen?

Thanks,

Bill
