Sorry, i surely ment the geneal relativity :-D i say, i always make lots of misprints :-DD sr is not what interests me much

That is not really a question... That is a kinda general statement. For i doubt u have real idea of Extra Dimensional Models Be honest. This model is surely nice, for it provides great freedom 4 developing new ideas and applying almost any method u invent (assuming u have enough fantasy and skill to build a good axiomatics for that) and so on, but again, i donno what to say for the question was very general. if u wanna ask something more specific..... but well, as for Planck scale, it is supposed to be about 10^(-35)m, but these are just theories, because strong, weak and electric interaction can somehow be combined (still there is no single point of view on that question), but the gravity stays 'untouched'. At least recent works seemed unconvincing.

hehe, i seem to have come to a wrong place, but i was just curious Simply speaking: Travelling at a speed.gt.c is not forbidden (mathematically), but crossing the very barrier of c is impossible due to singularities. Though i must say some of modern theories (mostly raw and incomplete) keep trying to develop methods to 'avoid' this singularity. And again i must say - that is only maths, we never know what is real, for math is just a kinda language (and we often make mistakes and misprints in it, like i do for instance )))) First of all, ppl have to make sure, that special relativity (u remember what it states, don't u. adbout the equality of masses ;-)))has a right to exist, for it has only been indirectly prooved in experiments. And that is what i would suggest you to think over, 4 it is interesting indeed.

I wonder how many of you (all of you) HAVE finished school. I am wondering just because such conversation is far from being interesting. You r saying things known to every teen (or i mean things that SHOULD be familiar to every teen). I am surprised really, for i expected a kinda dicussion on some new points of modern theories (and there ARE lots of them, mostly based on pure maths + some efforts to involve 'sense', but still being contradictory) Come on, i am dissappointed... But if some of you is up to some work in this very field of theoretical physics - let me know. (Sorry, if i offended anyone - i really didn't mean to)
