Theoretically, could shrinking down to Planck scale enable time travel?

Click For Summary

Discussion Overview

The discussion revolves around the hypothetical concept of whether shrinking down to the Planck scale could enable time travel or time dilation. It explores the intersection of theoretical physics and science fiction, particularly in the context of popular media representations of time travel.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant reflects on the idea presented in a movie about time travel through shrinking, noting the vast difference between a second and a Planck time, suggesting a mind-boggling relationship.
  • Another participant dismisses the initial idea as silly, implying that previous discussions have led to similar conclusions about fictional concepts.
  • A different participant argues that shrinking to subatomic size differs from the Planck scale, stating that at the Planck scale, all physics breaks down and time dilation is a real phenomenon.
  • This participant emphasizes that their question is hypothetical and acknowledges the impossibility of shrinking due to the Cube-Square law, while still speculating on the implications of Planck time.
  • Another response critiques the previous comments as lacking scientific basis, labeling them as "movie technobabble" and asserting that the discussion strays from actual physics.
  • This critique also reinforces that the sci-fi section is meant for discussing actual science fiction rather than speculative physics.

Areas of Agreement / Disagreement

Participants express disagreement regarding the validity of the initial hypothetical scenario, with some viewing it as nonsensical while others attempt to engage with the speculative nature of the question. The discussion remains unresolved, with competing views on the relationship between the Planck scale and time travel.

Contextual Notes

There are limitations in the discussion regarding the assumptions about the nature of time and physics at the Planck scale, as well as the definitions of time travel and its feasibility. The conversation reflects a mix of speculative reasoning and critiques of those speculations.

I remember one of the Ant-Man movies had time travel enabled by shrinking down to an incredibly small size. This seemed silly to me at first but then I realized that a second is much closer to the age of the universe than a Planck time is to a second. This is mind-boggling and the human brain cannot register how a Planck time operates. Even though it is completely impossible, if you could shrink down to the Planck length; would it enable some sort of time travel or time dilation? Maybe that IS the key to time travel and since shrinking humans is completely impossible; therefore time travel is completely impossible

And you were correct.

The last time you asked if something in fiction was possible, we said no, and you were unhappy. I hope we don't repeat this.

Gee what a surprise. A condescending answer from Vanadium50. I bet you have an alert on me.

Shrinking down to subatomic size is different than Planck size. Planck scale as I said “a second is much closer to the age of the universe than a Planck time is to a second”. At Planck scale, all physics breaks down. And time dilation is a real thing.

Shrinking down is impossible due to the Cube-Square law BUT my question is a hypothetical and I posted in the Sci-fi section. I just was speculating if this could be possible due to how Planck time works.

I'm not V50 so I'm not sure if you'll like this answer better or not....

Everything you just said is barely above gibberish. Sorry, but it's just movie technobabble and doesn't really bear any resemblance to real physics.

That's not how our rules work. The sci-fi section is not a section where the rules on speculative physics don't apply, it's a section for discussing actual sci fi. Since that's not what you are after, this thread is closed.
