Wait a second. Amy Pond should've created a paradox!

[BlastHardcheese]

When she sized up her younger self and grabbed her hair. Hasn't it already been established that physical contact with one's past self causes time vortex-shattering events? Rose made a bad paradox worse by getting close to her infant self in Father's Day and the Bridagier did the same in Mawdryn Undead(with an oddly positive result of the time explosion killing Mawdryn's people).

All the same, the writers seem to have forgotten that contact with your past self does horrible things to the space-time continuum. I guess since space and time were already falling apart, this little paradox was like a fart in a hurricane?

They were disconnected.

It was impossible for Amy from the universe without stars to grow up into the Amy with stars because she lived in a universe which hadn't been all but destroyed.

Mirror universe rules not crossing timeline rules.

I look it as one of two things. Either:

1) Amy touching little Amy did have an affect. The pocket universe surrounding Earth did chug along fairly well, with the odd bit of zanyness like the Penguins, until Amy emerged from the Pandorica. It was then that things started disappearing.

Or 2) The Universe was ending already, the normal rules don't apply.

Though Guy's post also makes a bit of sense.

 

[Alidar Jarok]

Yeah, I think any of those three explanations makes sense.

Words never before spoken...

Just kidding Guy

This is my interpretation, too. It's also possible that this was a way of Moffat showing us that something is "special" or "off" about Amy, because otherwise there's no way they'd allow her to touch her younger self within only a few minutes of the Doctor demonstrating the Blinovinch Limitation Effect, or whatever it's call, with the screwdrivers. It had to be intentional. Just like the Doctor's jacket in the angels two-parter. It may not pay off until the final episode of the split season, but I'm convinced there's a reason for it.

The entire Universe had already suffered total event collapse, remember? Can't get any more time vortex-shattering than that. You might as well complain that the basement might collapse on a house that had already imploded.

Bingo.

 

[Guy Gardener]

Hmm.



I suppose the doctor is immune to paradoxy stuff when touching himself causing problems since he grabbed himself just before he pretended to die on the steps in the museum.

^ Well, the Doctor's never had any problem making physical contact with a past or future version of himself before...
