h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

The need of a title is extraordinary gigantic ...
I have tried to get some help about a physical problem
and nobody understanded what I am trying to say
and so I became what I became.
Thanks for that kind of inspiration.
(Is this an english word ? My word book didn't know it,
but you know what I'm trying to say)

Well, your point would have been clear if you had come up with the most intriguing point first --- what if someone shines a torch out of the front of a starship travelling at 1/2 the speed of light. What if the spaceship speeds up to 1/1 c ?
What if the rear light is on in the latter case -- do we then have a standing light wave in space?

Don't worry about it . I guess some of the most important scientist have been misunderstood... maybe some of their theories only make sense because they were misunderstood.

O.I.C !! Now it all makes sense to me
Just the same way like modern 'artists' work, by giving no explanation of meanings at all, but waiting for some critic to write horrendously long comments about the universal meaning of the artwork, its deeper sense and influence on the life of all living mankind and creature, and then simply nodding at that.

All I can say is that you're right.
In deed it is an fascinating effect when you could travelle at light speed.
There are many paradoxons concerning this law of nature.
That's my problem.
Everyone thinks about another problem.
And the only thing I wanna know is whether there exists another way
of measuring or calculating the velocity without using the formula:
velocity=distance/time.
If I'm right with my theory that everything in the universe is on the move,
nobody could measure the absolut velocity of an object A, but only its velocity relative to
an object B. Because the object B is also moving the velocity relative to an object C could be
different. Sometimes more, sometimes less always dependent on which object you choose for measuring.
The result of this would be that nobody could measure the light speed as the fastest velocity
in our universe. Maybe my mind is to limited to get the decisive point.
So time must be really relative.

What about doppler frequency shift? Does not rely on measuring a distance!

Provided that you have a lamp in front of your spaceship
(like the carrot in front of the donkey to encourage him to walk)
and you know the frequency of the emitted light you could always calculate
your real speed. Because the light will be emitted always with light speed
(I hope Einstein was right) and the spaceship will fly faster through the wave
and the frequency will be higher for the observer in the spaceship.
In this case you also need the moving object relative to you (the lamp) but you don't care
how fast the lamp is moving because the emitted light's velocity is always the same.
This could work !?
Thanks for the hint.

Should work, as long as you've got the maths right, that ugly relativity square root equation...

BTW, did you read the invitation in the other "You are right" conversation ?
