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

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.
