Faster than Light?

The theory of relativity claims that the motion of physical objects
cannot exceed a speed of 300,000km/sec. However, we know from
experience (e.g. equatorial rocket launchings, multistage rocket
vehicles etc) that the final velocity of objects is their starting
velocity plus their own velocity. There is no reason to believe a
maximum applies.

A spaceship travels away from star X at a speed of 300,000km/sec (v1).
The spaceship fires off a rocket from its nose. It has a velocity of
100km/sec (v2). The speed of the rocket is now 300,100km/sec (v1+v2),
i.e. the rocket travels away from the spaceship at 100km/sec and star
X at 300,100km/sec. Special relativity however demands it can only be
300,000km/sec, the maximum velocity allowed by the theory. This is
only possible if at the moment of the firing the speed of the rocket
is reduced to zero or the speed of the space ship is reduced to
299,900km/sec or a combination of the two. SR cannot provide evidence
or even a theory to explain how the reduction is possible or occurs.
It relies on the mathematical formula obtained by Fizeau (1819-1896)
in his experiments about the propagation of light through flowing
water in 1851. The formula is v’=v+w/(1+vw/vv). AE, citing Fizeau,
proposed this formula for the addition of velocities of all physical
objects (AE, ‘Relativity: The Special and General Theory’, Chapter 13,
Methuen & Co Ltd 1920). AE claimed it paralleled his illustration of
relativity in the train example he used to prove special relativity.
It has been swallowed by science ever since.

Even if you somehow did accelerate an atom to locally superluminal
speed, it would immediately decay in a process called Cherenkov
Radiation.

It would take near infinite energy to accelerate that small rocket
from the nose of your primary rocket moving at almost light speed.
Even if you could somehow get that energy, it would explode in blue
light as it reached locally superluminal speed.- Hide quoted text -

Luke,
there are already many particles moving at or near the speed of light..
They are doing very well indeed.

Peter Riedt

At the speed of light?

Name one.- Hide quoted text -

Eric,
photons?

Peter Riedt

Name another - photons are massless and should obviously be excluded
from this discussion.
