you guys only repeats what's been said already !

time is nothing... the only thing we can be sure of is that it exists...
like the fact that we exists we know time exists, it is up to every life forms to determine what it really is !

example... the day is when the sun comes up while th enight is when the moon comes up !
but fact is... if you take it solar wide, the notion of day and night do not exists at all as the sun and the moon is up there at all times ! thus time for me is relative to my own views of it while time for you guys is relative to your own views !

its as simple as that !
"we can't go back in time !"
again this is relative... i say we already can and do a lot of times in one day...
who knows, maybe we are all struck in a time loop where we relive our last 100 years in succession.
i mean i could die and then boom, time goes back to me be reborn again with no memories of my previous existence !

may it even be worse, when i'll die i'll be reborn reliving again and again my previous life but taking different paths at each one of it while you guys relives your own and time itself is the community of all of our decisions taken all together ! you see this for me i call the chaos theory ! it would prooves that time isn't a flowing constant but a very variable constant that change each minutes !

see what i mean, this is my view of it, while yours pretty much isn't the same as me, thus everything time theory wise will just be never solved for its up to everyone to decides what it is for them !
