A New Hypothesis Suggests That Parallel Universes Might Interact after All

A new conception of quantum mechanics rests on the idea that parallel universes exist, and that they interact with our own to create weird and wonderful quantum phenomena.

Quantum mechanics is hard to do. The great physicist Richard Feynman once remarked “It is safe to say that nobody understands quantum mechanics” and that statement was regarded as correct. The problem isn’t in the math, even an undergraduate can use Schrödinger’s equation, it is in what the math means.

Hey Bill Nye! Is the Multiverse a Paradoxical Idea?

The Many Worlds Interpretation is just one of a few multiverse hypotheses—but is there a glaring paradox in this popular idea?

The idea of a multiverse as we conceive of it was first mentioned by Nobel Prize-winning Austrian physicist Erwin Schrödinger in 1952, who warned a lecture hall full of people that this may "seem lunatic", but perhaps his equations did not show mere alternative versions of history, but alternatives all happening simultaneously. For this week's question, Austin wants to know about the multiverses paradox: if every alternate timeline happens, and anything that can happen does—somewhere—then wouldn't there be a universe that could not support the idea of any other universe existing? All multiverse hypothesis are as yet unverified by experiments, so it's all up in the air. But if we ever want to find out, the way to do it is by supporting space exploration, because the more we find out about the cosmos, the closer we get to knowledge about our own origins and the greater our capacity grows for multiverse experimentation. Bill Nye's most recent book is Unstoppable: Harnessing Science to Change the World.

The Life and Death of Schrodinger's Cat, and What It Really Means.

Schrodinger's cat is one of the most famous thought experiments of all time, but what does it mean for science, and what happens to the poor cat?

If you feel the need to put this cat in a box, you might be a physicist.
