A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics (NEW RULE as of 5 Nov 2024, trying it out)
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

If Eternalism is real (the theory of past, present, and future existing simultaneously) then time travel is going to a WHERE more than going to a WHEN. (lemmy.world)

Elaboration:

Imagine Spacetime as a movie film reel. All of time (past, present, future) exist at the same time just like all the frames of that movie exist on that reel. If you want to time travel you go to the frame location on that reel. That location we call a WHEN but it is also a WHERE on the reel. Also, when physicists state that time and space are interwoven a film reel analogy encapsulates that theory well. So, time travel could be simply going to a specific coordinate in Space.

Theoretical Physicist Sean Caroll uses the film strip analogy in this video:

Disclaimer: Obviously, I have been watching too many Youtube videos and none of the concepts are my own. But I did think of the WHERE VS. WHEN regarding time travel analogy as I haven't seen anyone state it that way yet.

Doesn't matter either way.

If you have free will, you can think you don't and do as if your destiny is already settled.

If you don't have free will, then it doesn't matter if you feel like you have free will and continue to think that you can influence your destiny.

Either thinking doesn't really matter because we can't know for sure if we do have free will or not so you can't make an informed decision.

So choose whatever interpretation you like and be your best self.
