--------------------
just forget about curved spacetime
light bends next topthe sun
becuase of the most simple reason
LIGHT HAS MASS !!!
(even Einstein ddint know to read his momentous formula

E=mc^2

the m there i snot just for garnement (:-)
so wake up idiots !!

the photon is **an exception to the rule** that

You are amazingly sure of this despite not having one shred of
evidence to support your claim. Then again, it is more important to be
original than be right, eh?

(even Einstein ddint know to read his momentous formula

E=mc^2


Show us the calculation of the deflection angle given the assumption
that photons have mass.

Einstein explained it as follows:

The light nearer to the sun (or the earth) propagates slower than the light
farther away


------ light ray velocity vectors
-----


X sun


Using the Huygens construction,
http://en.wikipedia.org/wiki/Huygens...snel_principle
we can find the wave fronts as follows:


¦------/
¦-----/
¦ /
wave fronts

X


The light propagates perpendicular to the wave fronts; consequently, the
light must bend.

lets see how do you *even startjust to * to think* about it **
hey little psychpath??

at least i know betetr than you (**much better than you **
about the mission we have
and have better information to just even come closer

sorry
my last response was ment about the Gold production
from Lead

now about calculating curvature next to the sun
it is no problem to fit(and fiddle ) the experimental data
to a calculation
that will look like a prediction of calculations
as Schwarzschild did ...........
the differenc ebetween clasic calculations of Newton
and schwartschied is the factor of 2

now since as i claime that
THE PHOTON IS AN EXCEPTION CASE
it should be calculated as an exception case
withthe factor of 2
and that is since we deally dont know
not me nore you
th ereal way the mass of the photon is spread and behaves
under the attraction of sun
fo rinstance:
the gravitation agents
might be the same family as the photon mass itself
and theit interaction(and mechanism' ) is actually inded unknwn
and above all that

E=mc^2
showes qualitatively the mass in the photron energy
so no need to show it quantitatively
the quantitative profe is enouigh
to make the **qualitative **p and theorethinc insight
that the photon has mass!!

Unfortunately, when one does that one obtains the wrong answer.

And, of course, when one attempts to measure the mass of light, one
obtains an incredibly small limit on its mass, which is consistent with
zero.

The best model we have for the propagation of light near a massive
object like the sun is GR, in which the curvature of spacetime is the
important aspect in determining the path light follows. And it agrees
with measurements to part-per-million accuracy over an enormous range.
