Ok now I understand this.
An observer in frame 2 sees the rocket lower on the y' axes and an observer in frame 1 sees the rocket higher.
There is no length contraction in frame 2 on the y' axes.
The triangle argument is only true when the speed is c, and just as PAllen wrote, on that...
Just as PAllen wrote, you may do this short derivation with two frames only because there is no length contraction perpendicular on the moving coordinate system for the photon.
So in my equal case I see an observator in frame 1 where a rocket is going on the hypotenusa and de x-axes velocity...
Thanks for your answer Fredrik.
I am very glad with this example, because after 1.5 years to be busy with this subject (between in of course, and it takes much time) I have the idea that I miss something in the time dilation concept and still see things wrong. That is the difference when you...
One thing I don't understand about the above triangle argument.
If you use other speeds in the triangle in stead of C (so V1, V2 and V) and you use t' = 1/γ . t you will find, this is only possible when V1=C and V2=C ?
Is time dilation not always equal perpendicular on the direction of...
Thanks for the answer Frederik, I go to rewrite this, I did it in a hurry late and of course I was thinking today between in, what I am writing and I confess it is not clear :) ...
During rewriting and I did with itex, I saw the problem and don't want to spend to much time to it.
If I could...
I was thinking when I take the Lorentz formula for a location γ.(x – v.t) as an observer in S and find the ratio compared with the location for an observer within the inertial system S’ it selves: 1/γ . Δx
But I made a mistake and took 1/γ. x
When I use the found ratio (for derivation...
Thank you very much for your answer PAllen en for the example Fredrik, I understand what you say (but still difficult, reason of my questions to be sure how you think), both says that both observers agreed about the same distance (no length contraction), even it are 2 frames.
So you say...
The Wiki triangle
I thought this was well known.
I citate myself :
"The much known triangle how Lorentz can be derived in a more simple way (see wiki). If a light source is moving horizontally which let bounce 1 vibrating photon (pulse, direction vibration is horizontally) vertically...
Thanks for your answer PAllen, yes I mean a photon (foton is Dutch), sorry.
What you explain I thought 1 year ago also about the triangle, what is the difference?
I had 1 year ago a little discussion with DaleSpam about the short Lorentz derivation (triangle) if a photon alone can be seen as a light beam.
1) The long Lorentz derivation seems me correct, so no discussion about that
2) For the short Lorentz derivation with the triangle (c.t , v.t and...
You intend that there is a very hugh theory behind length contraction and time dilation, its just based on the Lorentz transformation. I find it not very much ... can be lead to a lot of coincidences.
How I look to it right now (until somebody could convince me differently) it could be all...
Hi Vorde,
Sorry for the late responce. I responce now in steps, that's better I think. I am just not conviced about the term time dilation. But this could be the last station to be convinced. Interesting to have the opportunity to discuss this.
What is a 'meta-universe' effect ? Do you use...
Thanks for your answer Vorde. This is just to eliminate maybe a possibility for myself (and others maybe).
I understood in this forum that observers see things different. For any observer we choose his/her rest frame.
So every observer has a different relative speed to the target object. For...
I suppose if you try to explain the existing theory, with a thought, this is not against the forum rules..
So far as I know is our clock based on the rotation of the earth. So our time has defined in that way. Everywhere on Earth is our clock running in the same rate.
Suppose...
