Will we ever know exactly how the universe ballooned into existence?

Physicists have long been unable to crack the mystery of what happened in the moments when a vanishingly small seed ballooned into the universe. Now, one scientist thinks he knows why they can’t come up with a physical description of this phenomenon called inflation: The universe won’t let us. 

Specifically, the scientist describes a new conjecture that states, regarding the young universe, “the observer should be shielded” from directly observing the smallest structures in the cosmos.
