Quantum Weirdness...I think I have their album around here somewhere....

This is de rigueur. From Wikipedia...

Feynman diagrams are a pictorial representation of a contribution to the total amplitude for a process that can happen in several different ways. When a group of incoming particles are to scatter off each other, the process can be thought of as one where the particles travel over all possible paths, including paths that go backward in time.

( Emphasis mine. )

I already read that article...10 years from now.

[r_barton]

The Schroedinger edition had a centerfold. It was said to have been a beautiful cat, until you opened the pages in the center of the magazine. Never know what you’ll get.

“You can know when it is published, or where it is published, but not both.”

Thank you for my one hearty laugh of the evening.

Perhaps giant gas lenses could be built half the way to the moon to create the biggest telescope ever.

Seeing how “spooky action at a distance” occurs over space and time I don’t know why this new revelation is a surprise.

There’s also some quantum interpretations that have been around for decades that involve going back in time.

[Moonman62]

The argument updates Gottfried Leibniz and Ernst Mach’s idea that space-time might not be a God-given backdrop to the world, but instead might derive from the material contents of the universe.

...

IIRC Mach was a big influence on Einstein.

Only one person attended Leibniz’s funeral and he was buried in an unmarked grave, which shows you how much his contemporaries appreciated his genius. I don’t think either he or Newton invented calculus, but Leibniz invented a whiz bank notation for it.

Thank you for posting that. I haven’t seen that since the early ‘80’s.
