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.

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.

You Could You Be Surrounded by Tiny Black Holes and Not Even Know it

Each might be as heavy as an asteroid and as tiny as a decimal point.

Ever been attacked by a cadre of tiny black holes? Few of the well-adjusted would answer yes seriously. And yet, according to physicists the occurrence is not outside the realm of possibility. The universe may actually contain a multitude of tiny black holes careening through space perhaps on their own, or even in swarms. Though small, they are no less significant. Some of these could weigh as much as your average asteroid. At their heaviest, they would weigh a little less than the moon. Yet in physical size they would be tiny, 0.25 millimeters in diameter, around the size of a decimal point or the width of a human hair.
