    Loops Time
In summary, The concept of time looping and repeating itself, like in the movie Groundhog Day, is a science fiction idea that is based on the theory of General Relativity. Some physicists believe that it is possible with the use of exotic matter to create a wormhole in spacetime, but this is still just a theoretical concept. This idea of time looping also raises questions about the possibility of paradoxes, such as the grandfather paradox. The scientific term for this concept is a "closed timelike curve." However, no real evidence or discovery of wormholes or exotic matter has been made.

I was just wondering, if time can be dilated by gravity, can it actually loop and repeat itself (like movies), and if anyone was there it somehow witness it, they would see everything repeated? Sorry if this sounds silly, but I'm curious.

This more of a science fiction concept like Groundhog Day. The science behind it ie General Relativity mentions time slowing down for some observers. Looping back requires something called exotic matter to hold open a wormhole in spacetime which is allowed by GR.

Physicists are split on this often citing ideas like the universe forbids things like the grandfather paradox where the grandson goes back in time to prevent grandpa from meeting grandma and hence preventing himself from being born.

You can read more about it here:

Keep in mind that this is all theoretical and that no wormholes have ever been discovered nor has exotic matter ever been identified and discovered.

If you want to search for technical articles on the topic the scientific term is a "closed timelike curve"

Related to Exploring Time Loops: The Possibility of Repetition in the Universe

1. What is a time loop?

A time loop is a theoretical concept in which time repeats itself, creating a loop in the timeline. This means that events and actions that have occurred in the past will continue to happen again and again in a never-ending cycle.

2. Is time looping possible in the universe?

There is currently no scientific evidence to support the existence of time loops in the universe. However, there are theories and mathematical models that suggest the possibility of time loops occurring in certain circumstances, such as near black holes or in the early universe.

3. How do time loops affect causality?

If time loops were to exist, they would have a significant impact on causality, as events and actions would be constantly repeating and influencing each other in a continuous loop. This could potentially lead to paradoxes and contradictions in the timeline.

4. Can time loops be observed or measured?

As of now, there is no way to directly observe or measure time loops. However, scientists are studying phenomena such as black holes and quantum mechanics to gain a better understanding of the possibility of time loops in the universe.

5. What are the implications of time loops for the concept of free will?

If time loops were to exist, it would challenge our understanding of free will, as our actions and decisions would be predetermined and constantly repeating. However, this is still a highly debated topic and more research is needed to fully understand the implications of time loops on free will.
