Time is only a the perspective of conciseness. Without conciseness there is no movement of time

Absolute nonsense, there’s no such thing as time it can’t be identified or measured, only point that matters is the instant now

Thoughts could be imagined as when a pitcher is being dipped into a pool of reality to collect them. Then these mental processes are unfolding, given us the ilusión of time. Therefore time is the unfolding of mental processes that we gather the same way we gather water from a pool with a pitcher 😏😏😏

There is no such thing as time we as humans need to organise our life to make sense of it so we evented time. We live in a life in constant reality.

Time moving backwards is not the same thing as the things that happened become unhappened like the clip showing the mug pieces become whole again, or a person becoming younger again

I believe this cannot be understood without understanding that time is a physical quantity.

Thank you for clearing that up, appreciate it, so basically I won’t be dead in some twenty years or so (if I’m lucky). Is that what you’re saying? Unless you can stop that from happening, I’m afraid I shall have to go back to my scrolling in the hope of coming across a video with a beautiful girl on a beach somewhere wearing next to nothing. That will definitely stop me from worrying about the direction of time. But thanks anyway
