    Thank you.
    Next question: Was the citation in context of the OP discussion if time exists and if so in what forms?

    If time didn't exist, everything would have already happened at the same initial moment and we would never have to wonder if we could make it stand still because it already would be.

    What does "exist" mean?
  8. Motor Daddy Valued Senior Member

    It's a word we use in the English language that describes some physical or natural phenomena or concept that we communicate about.

    So a ball exists. A personality exists. Distance exists. Time exists. Volume exists. Space exists.

    Any word that describes some physical thing, some concept, or natural phenomena exists. Motion exists.

    Ideas exist! It does not have to be a physical object to exist. God exists in people's mind. God is not a physical object, God is an idea that EXISTS in people's mind. Is God a dude in the sky? Absolutely not!

    Love exists. Hate exists. Fear exists. Compassion exists. Empathy exists. Jealousy exists. None of those are physical objects and yet they exist.

    Yes, you can pretty much prove that.
    Considerably harder to quantify and record.
    Where? No, it doesn't. It's just an idea you have of where things in space relative to one another.
    Probably - by deduction we may conclude that the things that exist must be located in space.
    No, words do not exist.
    Motions is process carried out by a mobile entity: as soon as the entity ceases to perform it, motion no longer exists.
    Then the world is full of patricide, rainbow-coloured flying ponies, prom nights with nobody making an ass of themselves, brilliant PhD theses about flying saucers, a Trump dynasty ruling America forever and universal health-care.
    Then the word 'exist' has no meaning.

    Numbers exist. It can be proved mathematically.
    Logic exists. It can be proved using logic.

    Time only exists (for someone or something...) if you (it) can interact with something present in the same space-time.
    No interaction, no time.
    Per example : If some intricated photons expand/progress in the vacuum between the particles.
    Unless you interact with it, time is senseless.
    The 2 photon bounces alternatively into the domain they occupy, the domain expanding in the point of view of the observer at light speed.
    But into their domain (their space-time), the photons, at light speed (but in their domain...) are doing so many bounces we dont see.
    They are bouncing an infinity of times... in the point of view of the observer.
    But if you interact with "the domain" of theses intricated photons... you stop one of them, and so the other (his opposite) is now out of the domain (domain is broken if there is an interaction).
    So : There is an infinity of time in the domain and you can break the domain "at sometime" (looks paradoxal isent'it...).

    Are you claiming that time can exist for person A and not for person B, then?

    Can you give an example of time not existing for someone?

    Also, there are currently lots of objects in the world (indeed, in the room where I'm sitting) that I can't interact with now in any conceivable way. I might be able to interact with them in a few nanoseconds (at a minimum), but there will definitely be a delay before I'm able to interact in any way. It is non-sensical to claim that, therefore, time doesn't exist for me, or that it doesn't exist for those things I can't currently interact with. You're one of those things.
    Interact with it? How does one interact with time?
    I can't work out what you're trying to say, here. Perhaps you posted an explanation earlier and I missed it. So, I'll leave this.

    Yes, this is what i am saying (but not in term of existence but in term of value)

    Yes, the time inside a black hole is not relevant to the external observer (infinity is irrelevant in term of value)
    As soon as you are disconnected in term of interaction, time for one person doesent rely to the other person.

    You dont interact with time (but with the person)
    Time is time and is the same everywhere (therefore C is a constant).
    Only the point of view change.
