The link above shows Gravity, Light(photons), and Charge (I believe
sound waves also): all these weaken with the distance square.

How about Magnets...I think there's is the distance cube which is
strange since EM waves are made of photons and photons above weaken
with the distance square???

Then you thought wrong - magnets also obey the inverse square law. Of
course since magnetic monopoles have never been found the fact they
would
obey similar rules to charges is deduced.

-------------------------------------------------------------------------

Also from the same link, it makes me believe all these three forces
(Gravity, photons, charge) are the very same with the ***ONLY***
difference methaporicaly speaking is they each have a different
mass(energy)???

Then you are wrong. EM (unified by Maxwell in the 19th century) is
one
field described by a 4 vector. Gravity needs a 4x4 tensor called the
metric.


Therefore could Gravity, charge, photons be virtually the same in
the
same metaphorical way as light and EM waves are the same (both made
of
photons).

Check out Kaluza Klein theory.


A scalar as a 5th dimensions

Your inability to comprehend is showing again - that has nothing to do
with
it.
http://en.wikipedia.org/wiki/Kaluza-Klein_theory
quote:

1. "Theodor Kaluza who extended general relativity to a
five-dimensional spacetime"
2. ....."the final part(meaning 5th dimension) an extra scalar field
now termed the "radion".

When giving direct quotes give direct quotes not mangled bits with you own
words added whose sole purpose is to try and support what the article does
not support - all such tactics do is provide further evidence for the
obvious - you comprehension abilty is appalling. The quote is:
'The resulting equations can be separated out into further sets of
equations, one of which is equivalent to Einstein field equations, another
set equivalent to Maxwell's equations for the electromagnetic field and the
final part an extra scalar field now termed the "radion".'


3. Meaning of scalar and 5th dimension, quote: "The distance a particle
can travel before reaching its initial position is said to be the size
of the dimension."

If you meant size then you should have said size - the fact you did not does
cause something to spring to mind however - let me think - oh yea got it -
clutching at straws.



#3 above speaks of a scalar and not a vector ....

Nothing in that article says anything about 'scalar as 5th diemnstions' -
what you wrote does not even make semantic sense - if you believe it does -
as Tom would say - shrug. Either say what you meant in terms of something
that does make sense - or well take up --------.


example of vectors: x,y,z vectors form the balloon
exampe of scalar : the width of the balloon = scalar and the 5th
dimension


You easily say "no" that's not what they really mean but I haven't
found any arguments while reading the article that contradict it?

That because you do not understand the terms you bandy about.

seems too strange for my tastebuds,
strange how it can make a function out of the 4 other vectors with it
also being a vector but a scalar instead??
Are they saying something like 5th dimension = scalar*x*y*z*t ?

No.



It seems almost (using 3d instead 4d as an example) like saying the
scalar width of an inflated baloon made of x,y,z dimensions forms
another dimension? Are they saying that intensity or density forms a
5th dimension?

How about reading some articles on it and this time making an effort to
understand what they say? To start you off here is one

Therefore the main difference between Gravity, charge, and photons
would be the Energy(mass) that they contain.

For Gravity = mass (= energy) = density * volume,
For Charge = intensity * volume,
For Photons = intensity *volume

???

No.
