According to Einstein, the experience of "now" that we all share is meaningless

if you ask yourself whether you

know if the screen in front of you is

actually there right now so naively

would say yes of course it's there I

mean I'm holding it in my hand or I see

it directly in front of me but the speed

of light is finite and nothing can go

faster than the speed of light so

everything that you experience

everything that you see you see it as it

was a tiny little amount of time in the

past so how do you know that anything

exists right now what do you even mean

by now so this is the problem that comes

up in Einstein's theory of special

relativity and Einstein tried to

construct a notion of now in this new

Theory and he failed and he just came to

conclude that this moment of now which

we experience is fundamentally

meaningless every moment is now for

someone
