I was just wondering if there is any physics behind the time loops in the movies Groundhog Day or Edge of Tomorrow.
Gravity cannot cause time looping. As Jedishrfu already pointed out, it can cause differential aging, that's all.DHF said:I believe the only known mechanism to alter Time, is gravity. so if you had a situation where time was so distorted that it bent back on itself, then you would also be in the presence of a gravity well so enormous that time looping would be the least of your worries.
To be completely clear, gravity does NOT "alter time", it simply provides an alternate path through space-time which results in differential aging. Clocks always tick locally at one second per second.DHF said:I believe the only known mechanism to alter Time, is gravity.
Thank you for the clarification.phinds said:To be completely clear, gravity does NOT "alter time", it simply provides an alternate path through space-time which results in differential aging. Clocks always tick locally at one second per second.
Nice, though my ranking would be a complete different one. And 'Thrill Seekers' is missing! And 'The Triangle' (another one with Catherine Bell).jedishrfu said:Best time travel movies:

So many great stories here.

What do you mean by level? Also, are you talking about Closed Timelike Curves? I've heard of those recently.George Jones said:Yes, there is. At what level do you want an answer?
I have a basic background. I studied General Relativity and touched a little on CTCs, I'd like to hear your detailed answer though.George Jones said:Yes, I mean closed timelike curves.
By "level", I mean "What background in physics and math do you have?" It is okay if you don't have any background in physics and math, but I will try to write a detailed answer with your background in mind. This might not happen today.
Time loops in movies are based on the concept of a closed time-like curve, which is a hypothetical scenario where an object or person travels back in time and interacts with their past self. This creates a loop in time where events are repeated over and over again.
In most movies with time loops, the concept of time travel is explained using either scientific theories or supernatural explanations. Some movies use concepts from quantum mechanics, such as parallel universes or the multiverse theory, while others use supernatural elements like magic or curses.
As of now, there is no scientific evidence to support the existence of time loops in real life. The laws of physics, as we understand them, do not allow for closed time-like curves to occur. However, the concept of time travel is still a subject of ongoing research and debate among scientists.
In time loop movies, characters often experience a sense of deja vu when they encounter events or situations that they have already experienced before. This is because their memories are retained from previous loops, creating a sense of repetition and familiarity.
Time loops in movies often involve altering the laws of physics, such as the concept of cause and effect. Characters may be able to change the outcome of events by going back in time and making different choices. However, these alterations can also have unintended consequences, creating paradoxes and disrupting the natural flow of time.
