For years biologists have been wary of applying the strange world of quantum mechanics, where particles can be in two places at once or connected over huge distances, to their own field. But it can help to explain some amazing natural phenomena we take for granted.

Every year, around about this time, thousands of European robins escape the oncoming harsh Scandinavian winter and head south to the warmer Mediterranean coasts. How they find their way unerringly on this 2,000-mile journey is one of the true wonders of the natural world. For unlike many other species of migratory birds, marine animals and even insects, they do not rely on landmarks, ocean currents, the position of the sun or a built-in star map. Instead, they are among a select group of animals that use a remarkable navigation sense – remarkable for two reasons.

Quantum Mechanics Saves Grandfathers From Time Travelers

Mention time travel at a nerd party, and other guests will immediately respond with a grim conundrum: What happens if a time traveler goes back in time and kills one of his ancestors? This is the “Grandfather Paradox.” In a simulated environment, a team of mathematicians tested the paradox, and made a remarkable discovery: In time travel simulations, at least, history repeats itself.

The Grandfather Paradox makes a mess of time travel. A murderer kills his ancestor, preventing his own birth, thereby preventing the murder, thereby being born, thereby committing the murder, and so on. To observe it, a team of researchers, led by Martin Ringbauer, created a simulation. Instead of firing up a DeLorean to 88 miles an hour, they sent photons through a “closed timelike curve,” or CTC. The photons are paired up so that one follows the other. It works like this:

In their new simulation Ralph, Ringbauer and their colleagues studied Deutsch’s model using interactions between pairs of polarized photons within a quantum system that they argue is mathematically equivalent to a single photon traversing a CTC.

Simulation Theory and the Nature of Reality with NASA Physicist and Author, Tom Campbell

Via Midwest Real

IMG_5913“When the original founding fathers of quantum mechanics were doing these experiments they were really excited… making statements like- ‘if quantum mechanics doesn’t blow your mind, that’s because you don’t understand quantum mechanics.’ They realized this was a really big deal philosophically, (and) scientifically… Then they tried to come up with a good explanation. They couldn’t find one… Now they just blow it off as ‘nobody will ever know… it’s just weird science.’ This My Big Toe theory though, explains it.”  -Tom Campbell

If that chopped up quote sounds vague, pseudo science-y, or confusing (especially if you’re not familiar with some of the basic ideas behind quantum mechanics) I get that. But, when you’re grappling with huge issues like the very nature of our reality and you’re trying to take a broad stroke across the top, things tend to get foggy, so bear with me.

(You should know about the infamous, hotly-debated double-slit experiment covered above for this talk.)

Actually, don’t bear with me, or take anything from me, because our guest, Tom Campbell has an impressive career in applied physics.… Read the rest

Is Death An Illusion? Evidence Suggests Death Isn’t the End

Robert Lanza, MD sheds some light on  death with quantum physics.  Or does he?

via Robert Lanza: Biocentrism

After the death of his old friend, Albert Einstein said “Now Besso has departed from this strange world a little ahead of me. That means nothing. People like us … know that the distinction between past, present and future is only a stubbornly persistent illusion.”

New evidence continues to suggest that Einstein was right – death is an illusion.

Our classical way of thinking is based on the belief that the world has an objective observer-independent existence. But a long list of experiments shows just the opposite. We think life is just the activity of carbon and an admixture of molecules – we live awhile and then rot into the ground.

We believe in death because we’ve been taught we die. Also, of course, because we associate ourselves with our body and we know bodies die.
