Time Doesn't Exist? Scientists Say Reality May Be Very Different

Depends.

Time is relative.

At the horizon of a black hole "Time" slows and stops.

Time Space and gravity are all related and part of the same "thing". Your clock on the wall run faster than a clock in the floor. Because of gravity.

Time is really just a way to measure entropy. Tho time is not simply entropy, but entropy defines the "arrow of time," distinguishing the past from the future. While time itself is a fundamental dimension of spacetime, entropy is a thermodynamic measure of disorder that generally increases, giving time its one-way direction.

I consider it a "flow". It's like a wave. We are riding the wave of our flow. We can slow it down by speeding up and speed it up by slowing down. But we cannot make it go backwards. Yet.

Time here on earth is not the same as time on a distant planet. Growing up I had assumed Time is the same everywhere in the Universe. Or basically block Time. It is not. It is relative. Time is relative it is not universal, but depends on an observer's speed and proximity to a gravitational mass, as explained by Einstein's theories of relativity.

"Now" only means something right here. There is no "now" light years from here. Asking what is happening right now in a distant planet is a nonsense question. You can cannot get to "now" light years from here because that is the past because of the distances between us.

Space (Nothing) Time and Matter are all part of the same thing.

And(as I have said before) Nothing Matters!

A lot.

(Without Nothing you could not have Something).

If you are into audio books I highly recommend The Order of Time by Carlo Ravelli and read by Benedict Cumberpatch.

It's well written and easy to understand (very little math) and it's read by Benedict Cumberpatch!
