WARNING : NOT FOR JEE ASPIRANTS as of now
I was reading about special relativity and got some doubts
I wud be glad for someone to clear these
DOUBT 1 : TIME DILATION
it is derived t = t' / √ 1 - (v/c)2 taking a ray of light moving perpendicular to direction of motion and keepin in mind C is a constant
but when we try doing the same thing by taking a ray of light moving antiparallel to direction of motion we get
t = t' /(1 - v/c )
why ? isnt it wrong
DOUBT 2 : TWIN TROUBLE ---- IS IT LEADING TO PARALLEL WORLDS ??
Acc to theory moving frames time runs slower
NOW consider trains moving in opposite direction with speed v always in straight line
Twins A and B are on the 2 diff trains
A observes : It is getting older , faster than B.
B observes : It is getting older , faster than A .
third person on platform observes : A and B grow at same rate !
what does it imply ? Multiple worlds ?
DOUBT 3 :
Have the above 2 paradoxes already been dealt with as they seem obvious . pls provide links
