Default Re: Semi-OT: We will go to Stars.

i once posted in the starfury forum about some holes in the classical physics theory that can (in a very far fetched way) allow FTL, my explanation in the starfury forum was most complete but the theory is the follow:

1. According to the classical physics theory nothing can travel faster than light, even light canīt travel fast than itself.

2. Pay attention in the "faster than" part, because velocity is only a constante of a object in relation of another object, an object, in itself, donīt have any velocity, it only have speed in relation with another object.

3. So, according to the classical theory, nothing can travel, in relation to any other object, faster than light.

4. But consider a light particle (i know that the light is sometimes a wave and sometimes a particle, but lets consider it a particle for this discussion) that is emmited in a particular direction (lets call this particle Photon A), now, another particle is emmited in th exact opposite direction of the first particle (letīs call the second particle Photon B).

5. According to the classical theory, Photon A canīt travel in relationto Photon B more faster than light speed but, since light canīt travel in any other velocity than the velocity of light (obvious this) them Photon A is traveling, in relation to Photon B, at twice the light speed...

6. Bingo, you have somethin traveling at FTL speeds, and at the same time we found a hole in the classical physics theory...


Othe theory, called "Quantum Entanglement" involves quantic particles that allow comunication in FTL speeds, and what happens is the following:


1. Create in a accelerator 2 quantic particles identical with one another, its alwo important that the 2 particles be created at the same time by the same event (i.e. in the same atomic collision).

2. Separate the 2 particles by a loong distance, a distance where you can measure light speed (you donīt need 300.000 kms because our actual instruments can measure quantum alterations in less tha a secont, something like 30.000 km is more than enough)

3. Now, change the state of the first particle (this can be done with another collision against the particle, but you will need several tries and particles because the majority of the collisions donīt change the particle state but instead create new particles).

4. At the same instant that the first particle changes state, the second partcile also changes, no matter how distant from the first, and, at the exact same instant, like the particles had some kind of FTL communication among themselves...


I know that the 2nd example only demonstrates FTL communication, and no FTL travel, but its a start....
