Over 50 years ago I did a very mathematical course at university on quantum mechanics. It was fascinating.
One thing I remember was that everything can be thought of as a wave function existing in all space and all time. What we experience here and now is just most probable. Tunnel diodes only work because there is a finite probability of electrons existing the other sides of a wall by a process known as quantum mechanical tunnelling.
Now, I may have some things wrong, but what this taught me is that a very radical view is equally possible. We experience time as going from the past into the future, whereas this may be totally wrong. What if memories are new every day? What if time is just an illusion? One thing is sure: in the next 150 years some of our views and assumptions may prove to be quite wrong. Think how are views have changed in the last 150 years. In the future I am sure we will look back in amazement.
What we know today is fuzzy. As time goes by we may change our world view radically.
