"In May 1971, Walker narrowly escaped death in a skiing accident at Mammoth Mountain, California. In a fall from a ski lift, Walker was pierced through the heart with a ski pole. He was taken to a hospital and pronounced dead. However, a doctor detected faint signs of life and rushed Walker to surgery, where his damaged heart was repaired. Within two months, Walker was working again."

This is something that I've always found fascinating:

"As such, a conscious observer may be indispensable, an idea further elaborated by one of us with regard to so-called “delayed choice quantum eraser” experiments. The bottom line is that we cannot know that detectors actually perform measurements, for we cannot abstract ourselves out of our knowledge. Recall Max Planck’s position: “I regard consciousness as fundamental. I regard matter as derivative from consciousness. We cannot get behind consciousness.” (Emphasis added.)"

For me at least, the inescapable conclusion is that a consciousness had to exist at, or before (if there's such thing as "before") the creation of our universe.

The alternative theory is that the universe is a set piece with all moves past, present and future already set in stone made by some 'event' that created this structure. Detectors actually perform measurements that to us seen to produce QM results that happen with our consciousness of the measurement but it's just the illusion of superdeterminism and a lack of the researchers 'free will' to measure outside of this structure.

Wow. @cmartinez is now a proponent of the Strong Anthropic Principle.
Nope, that's not it ... what I am is a strong proponent that the presence of a creator is a must for the universe to exist at all.

Detectors actually perform measurements that to us seen to produce QM results that happen with our consciousness of the measurement but it's just the illusion of superdeterminism and a lack of the researchers 'free will' to measure outside of this structure.
I don't like that alternative theory ... it makes existence itself meaningless ... then again, it's not about what I like or not... :(

It would be depressing, that's why the 'Matrix' :D keeps us in blissful ignorance of reality even when we see things in QM that make us question cause and effect with backward causation, in which future events can change the past if we measure. Time then is a coordinate, there is no past, present, and future or flow of time. The 'flow' is our limited senses and measurements interpretation of time passing instead of causation. Feynman’s path integral shows there really isn't an infinite number of possible paths from A -> B even if there are infinite probabilities. One logical interpretation of this is the universe as a block universe, in which the future already exists. Maybe QM is not universal (no backward causation in the larger macroworld beyond quantum effect measurements) so we are free. If it doesn't apply to humans or cats ( Schrodinger’s cat) how can we test this without access to the past?

Can we define a boundary between the microworld, where both QM is valid and backward causation occurs, and the macroworld where QM doesn’t apply?

One of my friends sent this in an e-mail earlier this month and just looked at it. Very interesting comments, good points too!

I've heard this speech before. I get more than a little choked up to hear such eloquence and passion from a fellow American speaking his mind to his neighbors. I've had plenty of public speaking experience, but I sure couldn't do what he did. Pretty sure I'd like to have a beer with that guy.

I heard a rumor that, early in human history, 50% of all children murdered the other 50% with a stone.

Imagine how much safer the world would be today if the politicians of the time had just banned stones.

I don't own a gun, but do care about my rights as a citizen, when my dad died we Inherited a bunch I can use when ever I want. But, I'm not sure I could say that a Liberal would want to have his or her gun taken away.

Just ask Woopie, she's got one plus she knows darn well the gang bangers do, I think it levels the playing field.

30-Year-Old Leaves The Nest — After Parents Win Court-Ordered Eviction
Michael Rotondo, the man evicted after months of wrangling with his parents, complied Friday with the ruling that a county supreme court justice handed down last week. Local media report he left the house in Camillus, N.Y., just four hours before his high noon deadline to depart.

Then he came back to grab a few more things.

But he did leave again, this time with 2 1/2 hours to spare. And this time with the aging car that had become a focal point of the roughly half-dozen messages his parents wrote him before going to court. The hatchback got a little help from some jumper cables, and Rotondo offered the members of the media gathered outside a tasteful honk of the horn before leaving the block.
