Sort of similar to the Great Filter theory, but applied to time travel technology.

In that case time travel would be meaningless regardless, impossible to prove, and doesn't matter.

Dumbledore disagrees. The type of timetravel that happens in HP: Prisoner of Azkaban is self-consistent. Same as with Rick's timetravel in the snake episode of Rick & Morty (specifically excluding the snake time travel, which is an example of non-consistency, leading to endless paradoxes).

Now ofc having a timeturner and/or a timemachine would be the impossible part there, but again, CTC's are technically allowed by GR.

  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
