The article needs a proper section on "multiverse theory", the many-worlds interpretation, or whatever it's called. If there's already another page, a link. The concept is brought up several times without any explanation until the end of the article.

What film does this line refer to? "The reason the universe is ending in Star Crossed is because of all the various paradoxes created by the Federation, from Jim Kirk to Captain Janeway."

Which one will 999: Nine Hours, Nine Persons, Nine Doors fit under?

There's also the example of the movie "Lost in space" And also "butterfly effect" uses 2 different ways of time travel. different dimensional time travel and the butterfly effect theory. Like why he had a knife when he was a kid.

This example was connected to a Legend of Zelda example in the video games section. If anybody can figure out what media type to add it under, go for it. If somebody is feeling ambitious, retool to to be added to the main Doctor Who example set. Please reply here if you've readded it so we don't have several people making the attempt.
- Once a Doctor Who Expanded Universe did that exact thing - that is, leading a musician into the future and having him hear a song he was destined to write. Problem is, he had still not written the song in question. The Doctor, horribly alarmed by the very real possibility the musician tried to rip himself off, warned him not to - as this would mean the song had been written by Time itself, opening the gate for many potential paradoxes to occur. Guess what happens.

Sub-point under "The Information Loop" removed from main page:
- Modern scientific understanding is, however, that information is explicitly not subjected to the preservation laws, that is, it can be created ex nihilo and destroyed completely, thus making the point moot.

I'm sorry but why does the Information Loop have a listing at all in this context? Warning your past self would be covered under the mentioned Reverse Grandfather, as its equally valid to warn yourself because you remember receiving the warning as it is to act to save yourself where you were saved in the past. A scan of the what physicists talk about as information seems to me to still be covered under the Object Loop as it deals with information within a medium. Thus Information only applies if one choose to warn oneself with the exact same warning item your past self received and kept. So I'm deleting the bullet and if someone can distinguish it as a third type better then they can add it back.

Another time travel paradox that is much less frequently noted occurs when their is actual 'travelling' through time that takes 'time', as (unless some coherent argument is given to the contrary) it essentially amounts to a self-referential, recursive action necessitating an infinite regression. (It requires time to describe a change in time.)

Digression removed from main page:
- Part of the problem with understanding stable time loops lies with quantum physics. Suppose a watch is sent through an object loop. Reasoning classically, we assume it goes through the loop time after time, getting older with each iteration. Quantumly, all the different version of the watch go through the single loop 'simultaneously', with the different histories interfering with each other in the usual quantum way. This can potentially result in mutually exclusive events both happening in some sense, not particularly unusual in quantum realms, but not something the human mind can comfortably intuit.

I think there should be a picture from MGS 3 instead of this comic. "Snake! You've created a time paradox!"
