From the Thor: The Dark World teaser trailer there’s a scene with kids approaching a truck that’s floating in the air, as if there’s no gravity. This is an anomaly that’s happening across the universe, something that has to do with the “fabric of reality” tearing apart as Natalie Portman’s Jane Foster says.
Producer Craig Kyle:
“This is the beginning of an element that’s spreading across the universe. We’re calling it right now the singularity. And it’s basically like a flex in the universe. If you think like there’s fault lines across the cosmos. They expand and contract about every 5000 years, and they’re felt on every world. So, this is the first sign of it on earth. And what is initially very fun, and playful, and cool ultimately will build across all the planets and very, very disastrous. “
