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 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 the speed of
the rocket is reduced to zero or the speed of the space ship at the
moment of the firing is reduced to 299,900km/sec or a combination of
the two. SR, by insisting on the maximum speed limit, requires the
reduction in the existing speeds and assumes that it does happen. It
cannot provide evidence or even a theory to explain how the reduction
is possible or occurs except that the Dutch physicist Lorentz asserted
that all bodies in motion are subject to the Lorentz transforms. As a
consequence, their length contracts in proportion to their speed, their
time is slowed down reciprocally to the length decrease and their mass
increases until at the speed of c, length and time equals zero, mass is
infinite and no greater velocity than c is possible. The transforms
were invented to account for the null result of the Michelson-Morley
experiment (MMX) which compared the times taken by a ray of light in
the direction of the motion of the earth and perpendicularly to it over
an equal distance. The relativity pioneer Poincare wrote in his 1897
paper 'The Relativity of Space' Quote: Lorentz could have accounted
for the facts (of the null result of MMX) by supposing that the
velocity of light is greater in the direction of the earth's motion
than in the perpendicular direction. He preferred to admit that the
velocity is the same in the two directions, but that bodies are smaller
in the former than in the latter. End of quote. However, Lorentz had a
third choice to account for the null result. He could have assumed that
instead of a contraction of the parallel arm of the MMX interferometer
equipment, an expansion of the perpendicular arm had taken place. This
would also have explained the null result with equal justification but
the three relativistic effects would have been reversed - i.e.
proportionally to the speed, the perpendicular arm and time would have
expanded and the mass would have been reduced. Needless to say that
both contraction and expansion conjectures are untenable. The solution
to the null result of MMX is quite different.

We know from experience???  What experience (experiment) has  shown
that?
The equivalent experiment is often done in labs with highspeed
particles, emmiting other particles in the 'forward' direction. The
speed of these emmited particles has never been measured to be greater
than c and has never been measured as "v1+v2".

And what do  you mean by "starting velocity" a nd  "own velocity"? Wrt
what these velocites are measured ?

Answer those first then we will continue.

Peter Riedt is one of those notorious top-class experimentalists
who has done an experiment where a velocity of exactly 1 m/s
was combined with a velocity of exactly 1 m/s and it gave
exactly 2.00000000000000000 m/s as opposed to the
1.99999999999999998 m/s that is predicted by the theory.
Together with Androcles, Jim Greenfield, Vertner Vergon,
John Polasek, and Mike (aka Bill Smith aka Undeniable aka
Eleatis) he will be nominated for the Nobel-prize next year.

And let's not forget r. b. winn whose cow-orker watched some metal
beams being driven around on a truck and observed no length
contraction; thereby falsifying the notion of length contraction.

Unfortunately I can't take this as a compliment, since you
so obviously and miserably failed to get the point (which
for obvious reasons I will not even try to explain), and
since you are too overall dumb to have a relevant opinion
on other people's knowledge to begin with.
But thanks for the effort anyway.

That one is almost too easy.  Your circuit is giving NOT XOR,

Assuming the standard usage that 0 is false, and 1 is true, yes,
you are correct for once.  In implication with a false
antecedent or a true consequent is true.  <0 implies 1>
satisfies both conditions.  It is basic logic.

Two cars each have speed 60 mph. If they are travelling in opposite

get damaged. If they are travelling in the same direction that cannot
collide.  That's the difference between speed and velocity.

Wrong. A fixed observer on  the ground measures the speed of a bus to
be 20 km/h. Inside the bust, someone is walking at speed 4 km/h wrt the
bus. The observer outside measures the speed of the walker inside the
bus. We do NOT obtain 20+4 = 24 km/h. That is experimental fact. (not
done with buses of course)

Thats correct, but is that what the original poster meant?
And 60mph wrt grnd + 60mph wrt fist  car <> 120 mph wrt  grnd.

Actually, *you* may call that the Principle of Relativity" but I don't
know of anyone else sensible that does.

All you've learned from your experience is the usefulness of a simple
approximation.
You may have also learned the convenient approximation that
e^x = 1 +x + x^2/2, which is also quite simple to compute, but just an
approximation nonetheless.

Yes, indeed, I deny that. I don't know where you got the impression
that the PoR is the EXACT vector addition of velocities.
Was that in an engineering course?

Ok, well, I'll repeat it.
The PoR is the EXACT vector addition of velocities.
Do you still deny I said that?

Of course you don't. You are fuckin' clueless.

I've never denied that you said that. You've said many stupid and
erroneous things, your statement about the PoR being the EXACT vector
addition of velocities being one of them. What other stupid and
erroneous things would you like to add to the list?

Androcles finds himself reduced to semantic quibbling over grave
concerns like:
- whether "Geschwindigkeit" means "speed" or "Geschwindigkeit" means
"velocity" and what minor confusion can be obtained by switching
capriciously
- whether "average speed" means the average of the magnitude or the
magnitude of the average and what minor confusion can be obtained by
switching capriciously
- whether "I said Einstein was a boob, do you deny that?" means "Do you
deny that Einstein was a boob?" or "Do you deny that I said that
Einstein was a boob?" and what minor confusion can be obtained by
switching capriciously.

I imagine its a terrible realization for him that he is now devoting
his time and attention to pointless heckling.

In that case, Androcles has descended to only semantic quibbling and
whining about a netiquette policy he finds annoying.

It is your policy to snip when beaten. And you are.
That doesn't annoy me at all, fuckwit bigot, I win.
Having written words that offend you, I chortle when you snip.
The PoR is the EXACT vector addition of velocities, by axiom.

"But the ray moves relatively to the initial point of k, when measured in
the stationary system, with the velocity (c-v)/(1+w/c), so that
t = x' * (1+w/c)/(c-v) with the help of the equations of transformation
developed in section 5" - Not Einstein.

No, actually, Androcles, you're wrong again. It's my policy to snip you
when it seems like an amusing opportunity to irritate you, nothing
more. Furthermore you are under the mistaken impression that something
you've said has ever offended me. I'm not offended by buffoons, I'm
amused by them.

> And you are.

In your mind, Androcles. Of course, in your mind, it's an axiom that
the PoR is the EXACT vector addition of velocities. Of course, in your
mind, there is a whole attic full of contused mathematics, idiotic
assertions, and a whole trunkful of physical oxymorons.

It is Androcles's policy to have the last word, apparently, even if it
is completely devoid of content. :>)

It's far easier to simply disagree with you than present any argument
you won't read, can't read or are unable to respond to, logical debate
with a bigot such as you is pointless.
There's no point in contributing to a reference that none of the "students"
will read or attempt to learn from. The intention was to focus on *exactly*
what is wrong in someone's thinking (which varies from person to person),
set it  straight, and then make progress from there.

Zaubermeister, the Internet is supposed to be a vehicle for the freedom
of expression but sometimes it is not. Try www.freewebs.com/djingattila
outside of Google or www.freewebs.com and then ask for djingattalia or

Ok, thanks. It worked today.
I had to give up after a paragraph, it reminded me of "See Spot run".
It's just my personal taste but I take the view that sentences should be
neither too clipped nor too long in literature lest the reading thereof
becomes a chore and detracts from the amusement.

If light cannot travel faster than light, how could anything else? In
order to get something physical up to that speed would use all of the
energy in the universe.

You can not run faster than yourself.

v4, yes you can. If you are running in a moving train to the front, you
are running faster than the train and faster than yourself relative to
the landscape outside.

Today only someone with VERY limited experience would say that. There
are literally zillions of observations for which this is not true.
Specifically, high-energy decays -- the decay products of an unstable
high energy particle do NOT travel faster than c in the lab, even though
in many cases the decay products travel ~c in the rest frame of the
original particle, and the original particle travels ~c relative to the lab.

Simple vector addition does NOT work, by very large factors.

Tom, you are correct if you accept the Lorentz transforms. I do not and
have explained the reason why they are incorrect in the second part of
my post.

We know from experience (experiments with fast moving objects) quite the
contrary. Thus your starting base is erroneous.
