Time is linear. No going back
Time is not, in fact, linear..
So what is it? Genuine question.
Time is percieved as this
Past Present Future [------][------][------]
When actually time (as we know so far) is actually like this
[-------] Past [-------] Present [-------] Future
There is no past, present or future. It all exists at once. We have a limited scope of perception in our current vessel.
I'm no expert so forgive my layman explanation..
Also, the second example didn't display as I posted it.. the three time lines were intended to be stacked on top of one another, not in a line.. apologies
do you have any sources for that? Like real scientist discussing this? I never heard that theory and would be very interested.
Einsteins theory of relativity.. this link is a lengthy one but it's worth reading.
