Huge plot hole problem with this movie


Time travel is impossible. And no machine/sports car can make it possible to go back in time

reply

Okay, I'll play...

How/why do you know time travel is impossible?

reply

How can it be otherwise? How can one go back in their past? What happens to the current? If you went back in time, then where would I be?

reply

A DIFFERENT WEBSITE,I HOPE.

You didn't answer the question. You are simply responding with more questions to which YOU can't imagine answers.

But, I'll still play the game with you.

"How can one go back in their past?"

Do you mean from an engineering/technology point of view? No idea right now... our current technology isn't advanced enough. But a 100 / 1000 years from now who nows?

"What happens to the current?"

i. Travel to your past could create alternate timelines, a common concept in most time travel movies. A new and different present is created, but you -- the time traveller -- still have a memory of your original future.

ii. Time travel of the sort presented in Looper, where there is only ONE timeline but it corrects itself to be self-consistent. The thing about this model is that NO ONE is aware of any changes to the timeline, NOT EVEN THE TIME TRAVELLER. The time traveller always remembers a different future... the one they created themselves. (Think of a feedback loop.)

Iirc Carl Sagan suggested that under this model, time travel could result in changes to the timeline in which time travel cancels itself out by never being invented.

iii. Look up the concept of a lightcone. This would allow time travel to the past but only in such a way that you can't encounter yourself and change the past. For example, you enter a wormhole and emerge 10 years in the past but 10 light years from earth. It takes you ten years to race back to earth travelling at light speed. You arrive just in time to see yourself entering the wormhole. You couldn't arrive faster to change the past.

So the present stays unchanged because the past stays unchanged, even though the time traveller went back ten years.

"If you went back in time, then where would I be?"

Under model i. you are here BECAUSE a time traveller created THIS present. The time traveller would have a memory though of a different future without you.

Under model ii. you are here BECAUSE a time traveller created THIS present. However the time traveller came from a fuiture in which you always existed in his memory. In reality, you didn't exist, but the time traveller's adventures changed the past and created the new future with you in it. The time traveller's forgets there was ever a future without you, and remembers you as always being there.

Under model iii. you were always here. The time traveller is too far away in space to 'erase' you from history.

You should really let Millsey blather on his own. I have become convinced he posts these numerous plot holes, of which I have yet to see a single one that is actually a plot hole, to irritate people. He's a troll. Plot holes have been explained to him multiple times by multiple people. He claims to understand, then makes the same "error" again. No one is that dense.

reply

I agree he's a troll, but as trolls go, he's pretty benign. I've never seen him (her?) attack anyone personally, indulge in name calling, etc.

It's a weird obsession... like TMC who always starts his threads with links to entertainment media articles, usually of the 'whatever happened to' type stuff.

I periodically respond to him in good fun as a mental challenge.

reply

I do agree that there is no evidence of malice in his posts. I respond on occasion as well; if for no other reason than to clarify the concept of the plot hole which is woefully misunderstood.

reply

He's not the only one who posts "this a is a plothole!" when it isnt , although he's by far the worst offender .

i'd be interested to see any genuinely correct "this a is a plothole!" threads.
I dont hink ive ever seen one .

reply

One thing to remember: Millsey himself has stated in other posts that if he doesn't understand something, he just labels it as a plot hole rather than try and figure it out. "Makes for a nice convenient answer" as he put it.

reply

Only a coward would resort to name calling and/or personal attacking one over the internet over a movie disagreement

Excellent job. I'll admit. You proved me wrong and I am taking back my plot hole

reply

I won't be alive if it becomes possible in 100 years but I imagine time travel would be relegated by law enforcement and they'd go with you in time to make sure you don't change anything. For instancce you could go back to 1991 and buy a brand new NES but you couldn't go back in time and stop John F. Keneddy from being assasinated.

reply

It's a MOVIE, Millsey72. And a SCIENCE FICTION movie to boot!

Anything impossible in real-life can happen in movies, and in science fiction movies, doubly so!

reply

I never saw a science fiction film that did not have plot holes

reply

It wasn't the sports car that made time travel possible, it was the flux capacitor.

reply

I really thought I replied to this, but I guess the post is too stupid to waste my time.

We're constantly traveling in time, so reality itself already proved that statement false.

reply

Many of my posts are stupid and its amazing they can get any replies to be honest

reply

Thank you for your honesty!

reply

Actually it's well known that we can travel into the future; we just cannot travel backwards (at least not to our current knowledge). A fast car or spaceship (traveling very fast, near the speed of light) can do this. But nearly all movies are quite impossible. It's fiction, fantasy, escape. So if unrealism is a flaw, then we can negate most movies.

reply

Have you ever built a flux capacitor and gone eighty eight miles per hour?

I don't really think you can talk.
