F = GMm/r2
That equation is proof that mass does not equal gravity.
well... this equation says actually absolutely nothing about the universe and proves the nonsense in describing reality with math... I will
explain.
but first, I come back to an example I like... how mathematics describes reality...
mathematically...
if there is a room with three persons inside, and five persons go out of that room, two more people need to go inside the room, for the room to be
empty..
go you get it ??
now... F ( force... a word that means nothing real ) in this equation is a product of a mass, a gram ( with any multiplier to it ) multiplied with
another gram and than divided by a distance multiplied by the same distance
m, the mass is something that is measured, same for the distance...
how do you measure?
you can do just two things, you can count, 1, 2,3..., and you can compare size of one physical "thing" to another thing
this is measurement...
it is very accurate with things you can take in your hand and handle with it, but it's nonsense if you try to do it with symbols... symbols that just
stand for something you can not collect or touch, like energy or time for example.
there is no other way in the universe you can do a measurement, period !
so... how a gram was created and where it comes from ? ...from comparison, here on earth.
the illusion an electron or proton here on earth has the same mass elsewhere in the universe is a wish, nothing else... an assumption !
as so many made by physics.
lets dive deeper into the units...
m * m = m2 ( in units )
r2 is distance * distance
here comes the trick
...there are to different masses in this equation in terms of "number", a one "M" and the other one "m"... this is a problem, you always have to
distinguish between them.
but in the derivation of this equation into the speed calculation of the centrifugal force
F = Mv2/r you just cancel one "m" as if they are equal in size...
and you calculate the orbiting velocity for a galaxy as
v = sqrt(Gm/r)
you can not do it... M and m is not the same!
but mathematical physics is doing it, and therefore,
the black hole "universe" is just one mass calculation...
now the force
F is gram over meter... doesn't matter how you look at it, a force is just a concept, there is nothing that has a physical property equal
mass/distance
this concept of force is what is told us as something "acting" on us ( matter ), and even the concept of space time, which itself is just stupid as
you can not take a distance between 2 charges, and than multiple it with counting that is depended on a background regularity ( constant periodic
effect )
multiplying comparison with counting is a mathematical construct, not a real thing
what is 2 apples times or divided by a period ??
but let us go back to the F in F = GMm/r2 as it's a singularity in the black hole
F goes to infinity if the density is = Mass/Volume and the volume goes to 0 in a singularity
but F is the force that acts on distance, is it not ??
the calculated force ( gravity ) upon an object in orbit is calculated like this, no ??
so if F goes to infinity and F acts on distance, we do not exist, we are all inside the black hole
in the Newtonian world anyway..
now... Phage said
Light is not bent by mass. Spacetime is. One way to look at it is that, within the event horizon, light is trapped in an orbit around the singularity.
this is a another way to describe the idea that a black hole has mass so big, not even light can not escape ( if you look from the center of mass to
the outside as escape velocity )
this is not what the math says, math says the gravity acceleration force is bigger then the speed of light...
whatever...
look at what I say.
every charge is a density in the field. +1 and -1 is 2.
the field strength is the separation between +1 and -1 divided by the distance between them,
but not the density of the field, it's additive and divided by distance.
also.. the speed of light is not constant, and you all know it, it is different in vacuum and slower in the air and slower in water and even slower in
glass.
why ??
because every medium it propagates has different amount of charged particles it goes, more field... slower speed,
this is a fact and telling me the field has no influence on the speed of light is just stupid !
the more charges you have in one place there more dense is the field, the slower EM propagates
this is how light is bend, not because of "spacetime bending curvature", this is nonsense and I have told you why !!
an EM wave has a true dimensions, it is not a point like photon, photon is just a name for the mathematical energy calculation.
EM wave has a with of the charge displacement and a length of the displacement's period. due to the vector of its displacement, it is not homogeneous,
so you have geometrically speaking two waves ( the slope in E intensity )
A transverse wave is a moving wave that consists of oscillations occurring perpendicular (right angled) to the direction of the charged particle
movement, and a longitudinal wave in which the displacement of the charged particle is in the same direction as, or the opposite direction to, the
direction of propagation of the wave.
As it propagates in the field, and the field has different density on different point in space, the field gradient changes.
Propagation of EM is slower in denser regions so it bends towards the bigger mass...
this is so simple...
the so called black hole is not a mathematical singularity but a very dense electric field.
nothing is "squished" into infinite density
this is why there are jets of mass escaping it, what would not be possible with gravity grater than the speed of light.
gravity comes from the field density gradient, as every charge particle is slower in the denser field, attracting other unlike particles...
but I think explaining it to you makes no sense as you hold to gravity as the MS is telling you
what is MS saying gravity is ??
bend spacetime ??
how exactly do you bend space ? ( distance, comparison )
how exactly do you bend time ? ( counting periodic events )
