Hi, Jeff, I know what you mean, and from what I've read, it is truly believed
that it comes into and goes out of existence.(Like at the event horizon of a
black hole.)

But (edit:) what you say sounds like my thinkings on light.
If we look at the sun, we know there is alot of light coming off it.
Everywhere the earth is around the sun we can look at it and see light coming
off it.
But, if we look left or right, we do not see all that light. We know the light
is there, we only need to take a step sideways and look at the sun again to
know light from each part of the sun is 'shining' everywhere.
And that light is not 2d or popping in and out, it is always there and always
real.

So, back to my thought that light, being on the electromagnetic scale with
radiowaves and whatnot, is actually a pressure wave coming off in all
directions from it's source. That it is not a particle. That we can make it
look like a particle.
What do I mean? Take a straight wave in the ocean(represents the 'wave' of
light) and put up barriers so that a section of it is forced to circle around
and into itself so that it peaks in the middle and resembles what we see when
we drop a stone in the ocean(represents the 'particle' of light).

Is there dark(as in mysterious) energy? or is there dark(as in unseen) energy?

So what do we know about light?
We can look at a light source and see it's light.
We can look away from it and not see it's light.
We can take a step to the side and look at it and see the source again.
The space all around a source is filled with this energy that our eyes let us
see with but it has to impact our eyes at a certain angle so we can know it's
there.
We can see it's reflected light, needing that certain angle, and know the source
is there.

Can light be 2 dimensional then? Only visible at the right angle?
or can it be the elusive 4 dimensional object we seek? Only visible as it intersects our 3 dimensions?
I've read that it is an electromagnetic 'thing'. An electric pulse with a
magnetic field around it. So now it sounds 3 dimensional.

What else do we know?
I'm going to reread the experiments about 'is it a wave or particle'.

For a while physicists had to be content with knowing that in some experiments light behaves 'like a wave', in others 'like a particle'. That changed with QED - Quantum Electro Dynamics.

QED correctly predicts the particle- and wave- like properties without saying that light is either.

You all know that what CERN is trying to do here is how almost every SCI-FI

based First Person Shooter starts. Some group of scientists make an error and

open up some dimension leading to Hell or some alien world. I personally am

really looking forward to the great Interdimensional War to come. Bring it on

giant Minotaurs with rocket launchers and mini-guns. Opinions?

Maybe a simple handshake and a smile.............
This solar system should be named "the Terran Neutral Zone"
