This forum so very often gives me a good laugh thanks folks..Most of the threads are to do with peoples perceptions of how they see things...I once has to do an assignment on when dose a fundamental postulate become no longer fundamental...and it was a hard one ! But I did pass What are your thoughts on this with regard to seeing it through the eyes of the posts on 44..A perception of peoples way of seeing things is just their own perception of things, and we all have our own..Like the Days problems in the court..or the way we perceive each others postings. knowing this.why oh why do so many members give each other such a hard time of things..



What is you thoughts on allowing people to be just how they are..How could or would you challenge a fundamental postulate )

Spider,

I postulate that you dont have eight legs.Do i assume correct,

Paul.

By the fundamental postulate of the theory of special relativity, the speed of photon A in inertial reference frame F1 is 299792458 meters per second.

By the fundamental postulate of the theory of special relativity, the speed of photon B in inertial reference frame F1 is 299792458 meters per second.

Since they are moving in the same direction, the difference in their velocity vectors (as defined in F1) is equal to zero. Thus, the two photons are not moving relative to each other.

Now, since the photons are not moving relative to each other, the speed of photon B in F2 is equal to zero. And F2 is an inertial reference frame.

By the fundamental postulate of the special theory of relativity, the speed of photon B must equal 299792458 meters per second in any inertial reference frame, hence by the fundamental postulate of SR, the speed of photon B in F2 must equal 299792458 m/s, therefore the speed of photon B in F2 isn't equal to zero.

Hence, we arrive at the following explicit contradiction:

The speed of photon B in F2 is equal to zero, and the speed of photon B in F2 isn't equal to zero.

Therefore, the fundamental postulate of the theory of special relativity is false.

See therefore that fundamental postulate is questioned and is no longer.. Its a little like saying IMHO..and most say that on here therefore if you question their posts instead of insulting the poster 44 may be a much better place to visit..Thats just my perception of the problems on here..you can always question as to why the have their opinion..
