    Well we can all dream in the meantime cant we? Or do we have to wait for proof? Or need the scientific communities approval to even have a thought not based on appropriate evidence?

    Yes, the scientific community is policing our dreams. But not you. You rebel!

    Perhaps some form of time travel is not forbidden by the laws of physics. The possibility of various types of paradoxes surely seem to preclude the SciFi versions of time travel. Example:

    Go back in time & murder your mother before you were born or in some other manner prevent her meeting & marrying your father.​

    I do not expect the typical SciFi version of time travel to ever be possible.

    The paradox I described in Post #23 is a strong argument against the possibility of the SciFi variety of Time Travel.

    Paradoxes & singularities are strong evidence against the validity of almost any proposed phenomenon.

    What???? Please explain how singularities are strong evidence against anything? I think supernovae and frogs are equally strong evidence.

    The fact that we can't make sense of it (even though it's something we've never experienced anyway) isn't really a good argument against it.

    It would be like Homo Erectus saying "the fact that airplanes are heavier than air is a strong argument against a working airplane."

    Dream - YES

    Wait for proof - NO

    Need the scientific communities approval... - NO

    Certain types of time travel lead to paradoxes, which seem to me rule against such time travel.

    As mentioned in a previous Post of mine: Consider going back in time & murdering one of your parents or otherwise preventing your birth.

    From my understanding of time which I think my post in this thread or another thread is

    TIME does not exist
    Only NOW exist
    The PAST does not exist
    The FUTURE does not exist

    To TRAVEL to another TIME is impossible because there is no OTHER TIME destination

    Agree . . . . "Absence of evidence is NOT evidence of absence" . . . . .(Wiki)

    It comes very close when not even a sniff of evidence wafts up the nostrils of what ever it is you seek

    Agreed. In fact this old cliche needs to be challenged: absence of evidence most certainly can be evidence of absence: https://en.wikipedia.org/wiki/Evidence_of_absence

    I need to clarify.

    Dinosaur and I were talking about whether it is ever going to be possible. Not about whether time travel is being observed now.

    So, restating my point: The fact that it is a mystery to us does not really lend credence to the idea that it can't occur in the universe.

    To restate like a cracked record

    My understanding in regards to Time travel

    TIME does not exist
    Only NOWexist
    The PAST does not exist
    The FUTURE does not exist

    To TRAVEL to another TIME is impossible because there is no OTHER TIME destination

    But I must admit this would hold only if the laws of physics are the same throughout the Universe

    Pssst I think they are

    ScFi versions of time travel ignore the issue of the traveler's spatial location after traveling in time.

    Say a person traveled 5 years backwards in time. How much has the solar system traveled in 5 years?

    It seems to me that the solar system has traveled a significant distance in that time.

    If the traveler maintained his current position, I expect that he would be far from the solar system & likely to be in empty space rather than on some planet.

    IMO, that may be why we have such difficulty in observing 'time travelers'. Something about 'windage', I think. Guess those temporal explorers need to do more research on positional dynamics? (<---all of this is intended as humor HAHA!)

    In a sense that fits in with my understanding of TIME not existing in that the so called traveler (ether way) does not have a destination to travel to

    The PAST does not exist
    The FUTURE does not exist

    Relative to what?

    That's a problem with that line of refutation. It requires some sort of absolute frame of reference.
    Which means it;s incompatible with relativity.

    We'd have to consider what kind of time travel is compatible with relativity.
