QM: Does Time exist?

For us, time moves faster and slower at the same time. Einstein's time dilation describes the difference of time that has elapsed between two events...measured by two or more observers moving relative to each other. The faster we go, the more time is affected.   I wonder if Einstein's theory of relativity bleeds over into our individual perception of two events that occurred at the same time.  Am I the same observer or two versions of me who witnessed two simultaneous events, but perceives the two events occurred at different times? I've spent much more time observing my marriage/husband than 911.  Is that why 911 seems like yesterday?

If I'm remembering it correctly, much of it had to do with Planck length (or maybe Planck time?) and the "nows" were separated by this. It's an interesting idea, but I sometimes wonder if this is just mathematics trying to find a different reality that may not actually be there. I never read Smolin's book. Valdez wrote: If consciousness (as we reckon it) didn't exist, then time wouldn't either. That's a curious idea worthy of thinking about. It sort of reminds me a bit of Donald Hoffman's studies on this in which he considers consciousness as something fundamental in the universe and the physical world emerges from that. It's kind of hard to wrap my brain around that, but curious nonetheless. Science boils down everything to just 2 components, energy and consciousness. All matter is energy fluctuations. Matter is not solid or motionless. If matter is comprised of energy, then can energy be comprised of consciousness? If so, the physical world emerges from it, along with the universe and anything in creation. Tis all a dream.. Isn’t Hoffman the guy who says (in essence) that we are in a construct similar to a video game, limited by a VU headset (our brains eyes and senses) that isn’t capable of giving us the entire view of our surroundings? That our perception is limited and basically created by our collective consciousness? Maybe it is a dream like Einstein said “a very persistent dream” lol

So, if we take a slice from his three points universe, and put other slices before and after it, even in a loop if we want, this sequence represents time, but we need movement. If the slices are pages of a book, time/movement consists in turning the pages. What Barbour says is that "the whole book exists regardless the turning of the pages" If each page represents a snapshot of the state of the universe, and if the whole book already exists, then the future state of the universe is predetermined -- hence, there is no free will. Our fate is already determined, as documented in "the book".

The concept of time is related to the succession of our ideas. We can perceive time in different ways depending on how fast or slow our mind is working. If your mind is occupied in a work environment compared to if you are doing nothing more than sitting in your chair. Time is not existing outside our perceptions. When I feel that the days are going too fast, I am always questioning myself if I am doing the right thing and if it's not better to slow things down in our everyday life. But  the sad thing is that we have to work if we can enjoy sitting in our chairs at home...
