Light from stars really from billions of years ago?

Flip a coin in a dark room. At any point in time position has any number of probabilities. A wave equation would predict the probability of coin being a in position if the light is flashed on and off.

When the coin comes to rest on the floor the wave function has collapse into a measurable state.

In principle not that complicated.

BTW, from a bio I read Einstein was a party animal of his day. He played a violin. He enjoyed eating, drinking, and smoking with his peers. He was hardly the stereotypical academic.

Having been in academia for a decent chunk of my life I can say that the vast majority of academics eat, drink, and party with their peers. Some even smoke. Many play instruments. I don’t know what the stereotype is but the implication doesn’t seem to fit with my observations.

It was said on a bio when people went looking for Feynman he could be found in a strip club sketching women.

Oh, you are one of those people....

Can coins also become entangled?

No. The coherence at the microscopic level breaks down for macroscopic objects.

I recommend the book entitled “Where Does the Weirdness Go?” By David Lindley. He addresses the transition from the quantum realm of elementary particles to the classical realm of macroscopic objects.

Product Description
Few revolutions in science have been more far-reaching -- but less understood -- than the quantum revolution in physics. Everyday experience cannot prepare us for the sub-atomic world, where quantum effects become all-important. Here, particles can look like waves, and vice versa; electrons seem to lose their identity and instead take on a shifting, unpredictable appearance that depends on how they are being observed; and a single photon may sometimes behave as if it could be in two places at once. In the world of quantum mechanics, uncertainty and ambiguity become not just unavoidable, but essential ingredients of science -- a development so disturbing that to Einstein "it was as if God were playing dice with the universe." And there is no one better able to explain the quantum revolution as it approaches the century mark than David Lindley. He brings the quantum revolution full circle, showing how the familiar and trustworthy reality of the world around us is actually a consequence of the ineffable uncertainty of the subatomic quantum world -- the world we can't see.

About the Author
David Lindley, formerly a theoretical astrophysicist at Cambridge University in England and the Fermi National Accelerator Laboratory in Illinois, has been an editor of the journals Nature and Science and is currently Associate Editor of Science News, in Washington, D.C. He lives in Takoma Park, Maryland.

I'd prefer a YouTube video rather than a 200+ page book to buy or borrow.... and I'm after steve_bank's coin analogy that "In principle (is) not that complicated"
BTW does that book talk about any delayed choice experiments?

I can never look at Feynman diagrams in the same light again...

BTW do you think that involves actual retrocausality with some of those particles (?) seeming to travel backwards in time?

excreationist, have you seen the light brother?

 

[excreationist]

Who's the light brother?

 

[skepticalbip]

Who's the light brother?

Just a guess but I think Steve just left out a comma. At least I read his post as, "excreationist, have you seen the light, brother?

Yeah I thought so but I didn't have an answer to that... Seeing the light implies knowing the Truth.... I wonder what Steve meant... Maybe also an attempt at humor...

Who's the light brother?

Pick one pilgrim. They are all the same light shining on reality. By the way, my CD on Seeing The Light is available. Free shipping.

What is one comma more or less.

Well the intelligent force I've been playing hide and seek with seems to have a sense of humor sometimes..... (e.g. Connect 4 and Upside down Bible (see description))

My son, embrace the cosmic giggle and you will see the light.
