It has been a common belief in philosophical circles for centuries, but not among physicists. Both Newton and Einstein thought of time as being one of the fundamental properties of the physical universe.
However, in the past decade or two, some theoretical physicists have now come back around to the idea that space and time could instead be emergent properties of a deeper, underlying reality.
If you really want to go cross-eyed, read up on the holographic principle.
This is the crux of quantum field theory, no? Where Newtonian and Einsteinian physics are all entirely emergent properties of fields that are governed by quantum principles? I’m in the cross-eyed camp so I’m way out my depth.
“Einsteinian” physics do unfortunately not arise from quantum physical principles, which is the major flaw in our current understanding of the universe. Quantum physics is very applicable to the microcosm, but cannot accurately solve for the macrocosm, while it is the opposite for gravitational theory.
In relativity time is a real dimension like space , but of a different type, and your speed in time depends on your speed in space and on your proximity to big masses, like planets. This kind of physics is necessary to keep the satellites synchronised otherwise their clocks go at a different speed from those on earth, so this is all very real and confirmed.
But this is consistent with what i said? Not moving and no mass = frozen in spacetime. Which is why it needed big bang as external factor to spread spacetime (i.e. change to unchanging environment). Right?
Time passes more slowly for you than for an outside observer, e.g., if you are moving to some place, for someone on the outside, your journey could take decades, while for yourself only minutes pass.
I thought it was widely agreed that time was a construct?

My favorite theory is that time and space are reversed in a black hole which could be at the beginning and the end of the universe.

The way i understand it is that a faster or heavier object has more energy, thus bends spacetime more.

What does it mean to move slower through time?

Wow that’s amazing to think about
Time passes more slowly for you than for an outside observer, e.g., if you are moving to some place, for someone on the outside, your journey could take decades, while for yourself only minutes pass.
So moving faster at some point starts to become slower because everything around you has the benefit of having more time to move?
Ah right, i got it the wrong way around again.
Time is, change isn’t. Time is how we measure change.
