I have found multiple conflicting collapse of reality situation due to explosion of TARDIS.
From The Pandorica Opens episode transcript:
WHITE: The cracks in time are the work of the Doctor. It is confirmed.
DOCTOR: No. no, no, not me, the Tardis. And I'm not in the Tardis, am I?
WHITE: Only the Doctor can pilot the Tardis.
DOCTOR: Please, listen to me!
WHITE: You will be prevented.
DOCTOR: Total event collapse! Every sun will supernova at every moment in history. The whole universe will never have existed. Please, listen to me!
CYBERLEADER: Seal the Pandorica.
DOCTOR: No! Please, listen to me! The Tardis is exploding right now and I'm the only one who can stop it! Listen to me!
From The Big Bang episode transcript:
RORY: What are you doing?
DOCTOR: Looking for the Tardis.
RORY: But the Tardis exploded.
DOCTOR: Okay then, I'm looking for an exploding Tardis.
AMY: I don't understand. So, the Tardis blew up and took the universe with it. But why would it do that? How?
DOCTOR: Good question for another day. The question for now is, total event collapse means that every star in the universe never happened. Not one single one of them ever shone. So, if all the stars that ever were are gone, then what is that?
(A large burning ball in the sky.)
DOCTOR: Like I said, I'm looking for an exploding Tardis.
RORY: But that's the sun.
DOCTOR: Is it? Well, here's the noise that sun is making right now.
(The Tardis noise.)
DOCTOR: That's my Tardis burning up. That's what's been keeping the Earth warm.
Exploding TARDIS took place of our original Sun to keep the Earth warm. But, these two quotes from transcript says, our original Sun either went Supernova (which isn't possible in real world due to inadequate mass) or never even existed. Both looks conflicting, but in either of case, how could the Earth survive? Sun's Supernova can easily kill Earth and if our Sun never ever existed, Earth can't come in existence (in case you are thinking about Earth revolving around the exploding TARDIS since beginning, it's also not possible as heavy elements to form a planet are only forged in the heart of a heavy star, not in the heart of exploding TARDIS which was keeping River Song in time loop).
