THAT DARNED PHOTON The photon is considered a massless particle.
  [I don't think it really is massless - nobody's figured out the
  NATURE OF MASS yet (I think I have, at least an explanation that
  works for me, but I'll get to that later)] Now when they talk
  about the uncertainty principle - either a quanta's location OR
  its direction can be measured, but not both at the same time -
  it's not so much that we change reality itself by looking at it
  - but rather it's more akin to watching a baseball get thrown:
  You throw a baseball. It arcs and lands in the pitchers mitt.
  You want to take some measurements. How did the ball travel?
  (direction) Well, let's say place you are throwing the ball is
  COMPLETELY DARK - you can't see the ball. So, you throw the ball
  in a gel substance and, after the fact, you work your way
  through the gel until you find the arc-shaped gap that the
  baseball made, and measure the empty space made in the gel that
  you can't see. This is akin to how they look for trails after
  they shash atoms - that can see which way the tiny particles
  went. But now you want to see WHERE the ball is located while
  it's being thrown. Again, you're in a pitch black area The ball
  is being thrown in a gel like substance. You want to find it
  where it is at any given time? You can throw ANOTHER baseball at
  it. (that's akin to the photon). You keep throwing the baseball
  at the travelling baseball until you hear a "click". You now can
  shine a flashlight through the hole made in the gel that started
  from your thrown baseball and stopped where the other baseball
  was travelling. Eureka! You've found where the ball WAS at one
  given point in time. But wait a minute! The ball didn't reach
  its original destination. Why? Because when you hit the ball
  with the other ball, you CHANGED THE BASEBALL'S DIRECTION AND
  SPEED. No longer is it traveling in that nice arc you had
  before. A wave/particle of light (photon) strikes the particle
  so you can see where it was. Or you follow its trail to see
  where its been (and can calculate where it's probably going).
  But you can't do both at the same time. But that doesn't mean
  that we change reality by looking at reality, because we're not
  throwing photons at things (our eyes do not eminate photons).
  BUT the SUN DOES, and artificial lights do. That's where skin
  cancer comes from. That's why colorful fabrics fade not only in
  the sunlight, but also under incandescent lights. Photons
  repeatedly striking something changes it, knocking off bits and
  pieces of it. That's what makes lasers so powerful -- organized
  photons, baby. It's ALL ABOUT THE PHOTON changing the structure
  of things, not about our minds. Observation=photons in that
  case. One badly chosen word in science leads to decades of
  misconceptions, many repeated by vaulted professors who don't
  look deep enough. I do believe that all of reality is has at
  least four spatial dimensions, which would explain protein
  folding (wanna blow your mind? Look up protein folding and find
  out what weirdness happens inside your own body when you chow
  down that 99 cent burger), why quarks seem to disappear and
  reappear, be in two places at once, etc. Physics is primarily a
  3 dimensional + time endevour, even particle physics. Something
  that moves at a 90 degree angle into the 4th dimension would
  seem to either disappear completely or be in more than one place
  at once (or in all places at once). We're at the point in
  particle physics, and physics in general, that the ancients were
  in when they saw the weird way that planets (wandering stars)
  travelled across the sky. They saw the weird ways that planets
  moved over long periods of time. They charted the movements.
  Straight line, squiggle, loop-da-loop, loop-da-loop, straight
  line loop-da-loop, loop-da-loop-, loop-da-look, squiggle.
  Somebody way back stuck a bit of math to the problem and figured
  out that these things weren't moving in weird ways across our
  sky but went OUTSIDE OF THEIR LIMITED PERSPECTIVE (which looked
  like wandering stars) and realized that the planets are all
  ORBITING. That was a MAJOR accomplishment, and I should track
  down who figured it out. I think the same thing is true with
  higher dimensions. This "weird behavior" will probably turn out
  to be higher dimensional particle physics. [can't say if it's 11
  dimensions ala String Theory but certainly at least the next
  higher physical dimension]. Gravity is already explainable in
  that way (remember the giant stretched out trampoline with the
  bowling ball in the middle to describe gravity?) . I think
  proteins seem to mysteriously fold into these critical shapes
  NOT due to some internal instructions based on DNA, but rather
  some kind of 4th dimension interaction - rather like slowly
  dropping a string into a bowl but WAY more complex. A 1
  dimensional string dropping into a 4 dimensional bowl might
  appear in the 3rd dimension as if they "know" what shapes they
  will fall into, when in fact, it might just be a property of
  folding in a higher dimension. Thoughts? _
