Most of us think of time as going forward from the past to the future. We have memories of our lifetimes and ways, with book, internet and objects, to look back at things way before we were born. We take it for granted that these memories have been forming since the day we were born.
However, this assumption could be wrong. Each day we could have new memories which we feel we have always had. Just like quantum mechanics turns our thinking on its head, so in 100 years from now we may find that time is just a man-made illusion.
