New Model Solves Grandfather Paradox

goldfishy writes "If you went back in time and met your teenage parents, you could not split them up and prevent your birth - even if you wanted to, a new quantum model has stated. Researchers speculate that time travel can occur within a kind of feedback loop where backwards movement is possible, but only in a way that is 'complementary' to the present. In theory, you could go back in time and meet your infant father but you could not kill him." From the article: "Quantum behaviour is governed by probabilities. Before something has actually been observed, there are a number of possibilities regarding its state. But once its state has been measured those possibilities shrink to one - uncertainty is eliminated."

Nibblonian 1: It's a genetic abnormality which resulted when you went back in time and performed certain actions which made you your own grandfather.
Fry: I did do the nasty in the pasty!
Nibblonian 2: Verily. And that past nastification is what shields you from the brains. You are the last hope of the universe.
