These Humans are crazy!!!

"When did that bolt of lightening hit the ground mate?"
"just as i got there!"
"And what about the second one?"
"IT TOOK RIDICULOUSLY LONG"
"really? The humans couldn't even scamper off fast enough when i saw them...are you sure?"
"POSITIVE"
"a friend of mine in printing said the humans wrote it as within '30 seconds' of each other."
" '30 seconds' ? what does that mean? i know it happened when i was around equator , and the second one when i was around the moon."
" i dont understand why they cant describe everything normally? either it was before or after a definite event"

"These Humans are crazy!!!"

this is probably what a photon would discuss with another photon.
Our concept of time is flawed. that is according to them. and theirs would be flawed according to us. This is the major thing in the theory of relativity. first we must get our perspective right.
the underlying concept being in the most simplistic terms, as an object moves faster, time is supposed to go slower.
Albert Einstein, came up with this new perspective and showed it to the world.He said that everything depends on the observer.
i could say that 2 events were simultaneous from where i stand(logic would tell me i am in the mid point of the distance between the 2 places where the events occurred) where as a person at the place where event -say - A occurs, would undoubtedly claim that EVENT A occurred first!
but are we wrong? or is one of us lying? it would be incorrect to say either. we are both correct in our judgments.

Time is not absolute, like so many before Einstein felt. time is relative. if in the same example of the 2 events, a rapidly moving particle were to observe this, it would find that the 2 events were separated by a HUGE gap in "ITS TIME".

I get this knowledge from a book called ' THE ABC of RELATIVITY- By Bertrand Russell"
the only absolute is the velocity of light. no matter who the observer, or where they are, or in what motion they are.
the book uses an example to show this. if i am on a crowded street, and i suddenly open a source of light waves that propagate in all directions...after the first second i would say that the light from my source is 186,000 miles away from me.
The fun part is...an observer who has his watch matched exactly with mine and would be about a at some distance away from me, would at the same instant say quite accurately that the same light was 186,000 miles away from him too!
thats the implication that when your moving as fast as light...time has different meanings all together.

no wonder they would think " we humans are crazy".

ps: the theory of relativity is something that is amazing and also something that i with my limited understand of this will be unable to explain to anyone. i provide my apologies if any of my analogies in the post are inaccurate and are irreconcilable with the ideas presented by Einstein.

Yes, it is interesting and one can wonder about its implications for hours.
Think about a star 10 light years away. The way you see it now, it was like that 10 years back. If you happen to travel at the speed of light, you would reach the star in a further 10 years, come back at the speed of light (another 10 years). When you would be back, you would be as young as you were when you left.
Time stands still at the speed of light. You were on par with the flow of time (ie ignoring the effects of gravity which is another issue tackled in the 'General theory').
So as you pointed out, you, from here will be correct in saying the star is like that 'now'!

I dont know if age will factor in very much, which we can count as the human body's fatigue.
but yes, it would only mean 10 years for ppl on earth, for me who riding on the photon - impossibly so- still would be as if i never left the place.
but i suppose we on earth must always talk about these physical indefinite entities for sake of convenience and to avoid confusion. Even though our implications when using such entities is far from what would be accepted as a physical fact.

yes yes...
that is why stars are so romantic...
30-40 years down the line when ill find a girl...and when we will be lookin at stars...
this is wat i am gonna tell her...
