You can come up with the words and you can wave your hands, but then you got to write down the equations; and I did. And I figured out that it could help with the dark energy, the acceleration of the universe; it doesn’t help with dark matter at all.

The single best reason in my mind to be skeptical about many-worlds is not because it doesn’t make sense or it doesn’t fit the data or I don’t know where the worlds are going or whatever, it’s because to make that extrapolation, to take seriously the equation that we know is correct in other regimes requires new philosophy, requires a new way of thinking about identity, about probability, about prediction, a whole bunch of things.

In the progress of science, the words that would be used to give the most fundamental description of how you were predicting the sun would rise changed because now you have curved space-time and things like that and you didn’t have any of those words 200 years ago.

There’s one difference that is important, which is the following; If you have a curve in space, I’m going to draw it horizontally, because that’s usually what we do in spacetime diagrams, if you have a curve in space, you’ve heard the motto before that the shortest distance between two points is a straight line.
