This issue has confused and dumbfounded physists for decades now.
Einstein's Special Theory of Relativity as I mentioned before states that
gravity is a warping of space/time causing all matter to "fall" towards
other matter. The "classic" third dimensional representation of this is a
the taut rubber sheet with basketballs and so on that "fall" towards
one-another. However, this is, of course, is a poor model as there must be
"ordinary" gravity at work to make the model work. Since the model
represents gravity, the introduction of gravity itself TO MAKE IT WORK makes
it a poor model, HOWEVER, it is perhaps the best way to get your head around
it. You have to imagine the same model however it is the warping of
space/time that draws matter (like planets and suns) together.
Experiments have proven that gravity can "bend" light, therefore it's safe
to postulate that gravity DOES effect electromagnetic waves, but I tend to
believe this effect is very small as it takes a whole lot of gravity (light
traveling close to an enormous body or black hole) to effect light which is,
of course, a type of electromagnetic wave.
There have been many studies, primarily conducted at Caltech, to actually
detect gravitational waves or the "graviton", yet results remain tangential
at best.
Obviously, if there is a gravitational wave or graviton that all matter
projects and is ALWAYS attractive, it is going to be a VERY weak force,
unlike electromagnetism and the strong nuclear force. Perhaps we lack the
technology to detect such a weak force.
Again, I tend to always go back to the warping of spacetime as the cause of
gravity. For instance, we know clocks run slower when close to the earth.
Yes, gravitational waves "might" (because we have yet to detect a
gravitational wave or graviton) cause the same effect but as I stated
before, the theory of a warping of space/time seems more elegant.
But to your piece, Greg, having researched this, physists have yet to find
ANY connection between electromagnatism and gravity, other than very strong
gravitational effects can "bend" light. That's it.
Gravity is something completely different and as yet not fully understood.

With this in mind, I am going to share with you a delima I have been
engaged
in for over 20 years: What EXACTLY is GRAVITY.
I don't know but back in the 80's there was an electronic magazine that
had an article
about making a detector. I had doubt, but I was recording something that
fit
the description in the article. I was recording symetrical waveforms
to a stripchart. The time interval varied from several minuites on up.
I never did it again. Here is that info....

Yes, I know, this has nothing to do with Car audio but I know there are
some
very bright folks who read these posts and I'm curious what some of you
might think.
Sir Issac Newton wrote the "owner's manual" about gravity. We can send
ships to the moon, predict projectile paths, and send probes throughout
the
solar system and beyond.
He wrote the "owner's manual", but NO ONE has deduced what gravity
ACTUALLY
is (the scematics of gravity ACTUALLY is). I exchanged many emails with
porffessors from CalTech and UCLA. But there is no conensus. What
FACINATES me about this issue is that gravity is such an important part
of
our life, yet we have NO IDEA the mechanics, or the medium, in which
gravity
operates. Enstein postulated (and this is my beliefe as well) that all
matter is drawn to all other matter (falling towards it) in the fourth
dimension space/time. This is why we do not percieve this accelerated
motion because it is a warping of space/time and we are not able to
percieve
this "falling" motion b/c it is occuring in the 4th dimensions.
Other physists believe all matter emitts "gravitons" that are ALWAYS
atractive in nature (unlike the elctron and neutron). YET WE HAVE NEVER
DETECTED A GRAVATON. That wouldn't be surprising as it's obviously not
electromagnetic, invisable, and we may just plain lack the technology to
detect a graviton.
I feel a warping of space/time is more elegant though it is VERY hard to
wrap your head around it. We are accelerating toward the earth in the
fourth dimension. Again, because we can't perceive the fourth dimension,
we
are not aware of the accelerated motion.
It's intesting to note how physisits try their best to ignore the
mystery.
YET IT'S SO DAMN IMPORTANT. We depend on gravity every single day, BUT
WE
DON'T KNOW WHAT THE HELL IT IS!!!
Instead, physisits focus on mathatical propertise of gravity itself, and
call that good enough.
The fact that gravity PERFECTLY duplicates accelerated motion again makes
me
believe it is a falling (all matter to all other matter) that occurs in
the
fourth dimension, space/time.
But I have spent countless hours reading about this, exchanging Emails
with
physisits, but again in our modern age it's absolutely INCEDIBLE we don't
understand one of the most important forces in the universe.
Anyway, if anybody has thoughts on this, I'd LOVE to hear them. This has
been a pet project for me for going on 20 years.
Take Care,
