Why do scientists think that time is an illusion?

2.93K views

It doesnt make sense to me… I know there was a past and there is a future although ‘now’ is fleeting. We measure time in days, weeks, months so how can it be an illusion? Oh and the belief that everything is happening now – what’s that about?

edit1: A lot of people are posting that time is not an illusion and where did I find that information from but there are articles where physicists state that it is. This is one:

I just wanted to know if someone could explain it clearly to me and I appreciate everyone who has tried to but it seems like a bit of a tricky and complicated subject. Thanks to all who have posted a comment.

Every physical law we know (and tested) is time symmetric, especially since mechanics (which is not only one of the fundamental theories, it is also one of the most tested).
Yet there is a very apparent paradox: We can remember the past, but we cannot remember the future. So time is apparently asymmetrical. But we do not know why, as all physics is essentially time-symmetric.
