This is a reasonably cogent explanation.

However, they call this stuff "Quantum Wierdness" for a reason. This sub-atomic stuff is peculiar.

Quantum physics is not only stranger than you think, it is stranger than you CAN think.

This was taught in my Quantum Physics class I took 14 years ago.

Notice I say it was taught. Not that I learned any of it.

This is when I realized scientists have no clue what is really going on
at the quantum level.

The problem comes when people mis-apply these scientific questions as philosophy, and then begin to think there are no absolutes at all because we cannot predict the behavior of electrons.

For some reason "philosophers" are fond of doing that kind of stupid stuff.

I would never say that there are no absolutes. I would just question our ability to find them...

I wonder if any of these so-called "genius" types have ever thought that their interferance pattern collapsing is a natural form of entanglement. You are creating a "quantum" dataset in the detector that mimicksthe state of the wavicle (wave/particle. http://www.cosmiclight.com/ofquasarsandquanta/wavicles.htm).

Don't bother watching the rest of it. It's a bunch of ridiculous new age crap. Over and over again it makes the claim that you can make things invisible to others by making them think they're seeing something they don't understand. It claims, among other crazy things, that Native Americans were unable to see Columbus's ships because the ships were invisible because they didn't understand them. A friend that teaches Physics loves to counter those new age idiot pseudo-physicists he has as students with the argument that women can see automatic transmissions .z

My uncle got a PhD in plasma physics. He soon left the field and went back to medical school in part due frustration with the establishment's unwillingness to accept that their models may be flawed.

He's a lot smarter than I am, but my understanding is that the universe seems to defy the accepted models and physicists are more interested in explaining away than understanding. Other scientists are starting to believe that our understanding of the universe is fundamentally flawed and the gravitational model is misleading. One group in particular is following the idea that electricity is at the root of everything.

Another thing my uncle told me is that Einstein himself stated that his Theory of Relativity assumes that the universe is electrically neutral and if that isn't the case, the whole deal may be invalidated. These physicists and cosmologists are starting to think that the universe is actually highly charged.

Anyway, this stuff is way over my head. Check out Thunderbolts.info. There is some interesting stuff there. Especially poke around and find the part about the Great Chicago Fire. Very interesting indeed!

The important part is that I recently found out that Carl Sagan personally disliked my uncle because he wouldn't fall in line with the party doctrine. That in itself raises my uncle to near-godlike status to me!

No, your body being there affects the outcome. Its your mass being there that affects the outcome. Every atom in you body is an observer.

Zero plus zero is zero. 0+0=0. Zero plus an infinite number of zeros is still zero.

If you slice the subatomic pie down all the way eventually you get these little vibrating strings or energy. If you interrupt them, they disappear. They are made of nothing at all. Everything, down deep, is made up of nothing at all.

In mathematics, (0+0+0)xN=0, but in the real world, if you cram enough nothing together, you get a universe.

One of my favorite physics laws is "Matter tends to exist." How pathetic. Caveman comprehension dressed up in pretentious speech.

You're putting the cart before the horse. Observations like this are what brought about the idea of harnessing entanglement.

there is no zero. zero is a human idea.

also the idea that matter tends to exist, is refering to relationship with anti-matter.

Nothing is nothing whether we are around to observe it or not. The number zero is a human concept, but the existance of a state defined as "nothing" is not.


also the idea that matter tends to exist, is refering to relationship with anti-matter.

It was originally stated because the question arose concerning the inflationary period and symmetry. While it is valid there, in a shamefully inexplicably way, it has also been used when attempting to explain why matter doesn't just dissapate.

I dont agree with your concept of nothing. I dont have time to lecture you either on why. I suggest that you study up on some:

Richard Feynman CAL state lectures(audiobooks)
Roger Penrose - The road to reality
Stephen Hawking - Nature of Space and Time or The Universe In A Nutshell

Good luck

I have read Feynman and Hawking, Dyson and a few others. Where you have no matter or energy, you have nothing.

The movie that was linked is BS. Some of the poitns it brings up are real, regarding the possibility that ours eyes can sense much more of the universe than our brains interpret, but the movie point blank states that God is a "backwater concept", and the we are God in and of ourselves. I accept quantum physics, and think there is great potential there - possibly even within our own minds, to bend and shape matter and reality to our will - but there IS a God, period. Everything around us didn't just "happen". Something (Someone) had to have MADE it. As for who/what made Him, my current theory is that time is non-linear - probably circular - and His origin is indeterminate. Read the "Wheel of Time" by Robert Jordan. Same idea - the books say there are seven "Ages", and we remember the prevous one, have myths of the one before that, and by the time the same age rolls back around, the Earth itself has erased all trace of the last time that Age came around.

Nothing but 4D space/time itself. From that, you will have virtual particals precipitating out of nothing, time will continue to progress, gravity "waves" from any given mass in the rest of the Universe, ect...

So no, you cannot ever have a "perfect" nothing anywhere. Even if it is only a single qbit of quantum fluctuation, you will have something there.
