Gravitation Is Not A Weak Force
Gravity is not the weak force you might think it is. You are only realizing a small part of the picture. There is an overall particle network in space that is responsible for gravity. Any masses introduced into the network create an higher tension -- that's what is thought of as gravity -- but there is more to it.
The Earth is of course pulling you down but space itself is also pulling you.
The Earth has a stronger pull (more connections) so it wins the tug-of-war.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
MEASURED GRAVITATIONAL FORCE IS EXCESS NETWORK TENSION
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ There is an all encompassing lattice-type tensioned thread particle network (not the string theory type) in space (and everywhere).
The network is made from individual yet connected particles and conforms to whatever shape it is surrounding. So light traveling through a curved thread particle network (like the Earth or Sun) will of course curve.
Is gravity curving the thread particle network? No! The thread particle network itself is what creates gravity (gravity is thread network tension).
Does this invalidate any of Einstein's equations? Of course not, it is just another way to look at it. Einstein has field equations and this is the field (thread particle network).

The thread particles are connected -- that creates a thread particle network. The thread particle network has tension on it so vibrations can easily travel through it on the threads (That's what light is).
Everything is connected by the particle network and it moves along with largest mass in proximity.

Any masses in the thread particle network will of course have / develop more connections and pull together.
NOTE: The mass(es) ●● in this scenario / instance would be balled up XY axis (plus +++ sign) particles. Everything is the same construct.

The thread particle network threads from any particle will go off in every direction but of course two masses in proximity will have a stronger tension between them than the thread particle network line thread tension coming from infinity.
The overall Dark-Energy-Like network tension pulls equally on everything -- let's call that force 100.
The two masses immersed in the thread particle network have a slightly higher tension between them (it's actually just more connections created by the network particles being balled up into matter) and that is all that is needed to pull them together -- let's call the tension force between the masses 109.


If you measured the force between the two masses you would get number 9 as a result -- NOT 109.
Force pulling together = 109, Force pulling apart = 100, Result 109 - 100 = 9
The overall force tension of 100 would be subtracted (you would not even know it is there)

NOTE: if you were directly in the middle of the masses you would of course be weightless and float. But that does not mean the tension or gravitational force was cancelled -- it is just equal pull on both sides. That's the main point -- no matter where you are you are always being pulled on from at least two or more directions.

A scientist fish living deep in the Marianas Trench would not know he is under extreme pressure and would not be able to measure it. He would only be able to measure changes or differences in pressure. Something similar must be true regardless of the theory (i.e. curved-space, gravitons, etc.).
And you cannot measure forces without the measuring devises becoming part of the measurement.

Notice the thread particle network tension 100 would be everywhere -- completely filling space and pulling on everything. Although it is the same thread particle network as gravity its force is in opposite direction -- that's the same effect as supposed Dark Energy. It is an expansive force but nothing is being expanded. Stuff can only pulll together.

~~~~~~~~~~~~~
VACUUM OF SPACE
~~~~~~~~~~~~~ Space is not a vacuum, it is normal, we are under pressure.
also... I'm sure the vacuum energy of (actually non) empty space is not a vacuum, it is tension on the lattice-type thread particle network (not the string theory type). I would bet my life on it.

It also explains (what they call) Dark Energy... everything is being pulled on (not pushed) equally from every direction (coming from infinity).
If there are two end points (any type of matter, planets or anything) that creates a stronger connection and they pull together -- that's gravity.

~~~~~~~~~~~~~~~~~~~~~~
WHY THE SPEED OF LIGHT IS "C"
~~~~~~~~~~~~~~~~~~~~~~ There is a high tension thread particle network in space (not the string theory type). Everything is connected by the thread particle network and it moves along with largest mass in proximity (something like what gravitational fields would be doing).
A good 2-D model would be something like a spiders web (individual thread lengths are approximately one Ångström).
Now imagine an infinite 3-D spiders web. If a vibration was set off in it, it would travel forever and the speed the vibrations travel (through the net) is the speed of light (that's actually what light is, a vibration traveling through a thread particle network)
The speed vibrations travel through the thread particle network is the speed of light "c"

The particle network threads have a certain amount of tension, length and mass. That makes 'c' the speed it is. If the tension, length or mass changed so would 'c'

Here is a regular thread tension formula...

Tension = velocity squared x mass / Length.

If we plug c in and rearrange we get...
TL = mc^2

Both sides of the equation are in joules or energy... equivalent to "E".
It means the Tension of the threads in space times their length is equal to their energy.

This is why the speed of light is involved in Einstein's mass energy equivalence equation...

E = mc^2

...and actually why light travels at the speed of light...
I always wondered why... now I know.
It had to be something mechanical... tension and thread lengths!

So, you can arrive at Einstein's famous formula from completely different directions.
You can think energy is contained in mass and released.

E = mc^2

Or you can think there is a particle network of threads and mass is inert, the energy is only potential... released (actually pulled) by tension on the threads.

TL = mc^2

They are equivalent. Which is correct? You do not know.

Tesla was correct...
"There is no energy in matter other than that received from the environment." – Nikola Tesla

Mnemonic memory device...
E for Einstein: E = mc^2
TL for Tesla: TL = mc^2

~~~~~~~~~~~~~~~
TENSION IS A FORCE
~~~~~~~~~~~~~~~ Tension times Length is equal to Energy.

 force = [M][L]/[T^2]   = kg_m/s^2
energy = [M][L^2]/[T^2] = kg_m^2/s^2

● The thread network has tension on it, that is a pulling force: Gravity
● The network is vibrating, that is energy, it's unseen: Dark Energy
● The network itself is a substance: Dark Matter.

NOTE: The " T " in the equation... TL = mc^2 ...below is tension and that's a force.
NOTE: The [T]'s inside brackets below are [time]

Here is a regular thread tension formula...
Tension = velocity squared x mass / Length.
If we plug c in and rearrange we get the one-inch formula for gravity, light, energy and time...
 
 TL = mc^2
|--inch--|

tension [M][L]/[T^2] * length [L] = mass [M] * speed c^2 [L^2]/[T^2]

The vibrations travel on the thread particle network as waves
So light is vibrations - waves - traveling on thread particles

~~~~~~~~~~~~~~~~~
DIMENSIONS AND UNITS
~~~~~~~~~~~~~~~~~ ........mass = [M] = kilograms
......length = [L] = meters
........time = [T] = seconds
...frequency = [T^-1] = seconds^-1
.......speed = [L]/[T] ...... = m/s
acceleration = [L]/[T^2] .... = m/s^2
....momentum = [M][L]/[T] ... = kg_m/s
.......force = [M][L]/[T^2] . = kg_m/s^2
......energy = [M][L^2]/[T^2] = kg_m^2/s^2
.......power = [M][L^2]/[T^3] = kg_m^2/s^3

Tension is a Force. Gravity is a Force. A Newton is a Unit of Force.
Velocity is a vector but the dimensions are the same as speed = [L]/[T]
The words like "speed" are only names of what the dimensions on the right are called.
You cannot have anything like pure length, force nor energy. (Pure mass? Yes, that is OK?)

Notice mass [M] is not equal to energy [M] [L^2] / [T^2] ...the vibration is missing

Here is what Einstein's (actually Émilie du Châtelet's) famous equation really looks like...

[M] [L^2] / [T^2] = [M] [L^2] / [T^2]

Energy already is a mass times speed^2.

If you could just lop-off parts of an equation and claim whatever is left is equal... i.e. "energy equals mass" then you could also say that "power equals mass" and so does momentum and force. It is really stupid to think like that.
Speed is NOT equal to length. Speed is equal to length divided by time.
Energy is NOT equal to mass. Energy is equal to mass times speed squared.

READ THIS CAREFULLY: Energy is just a word for vibrating mass (or substance). It's like "RED" -- you can have a beautiful redheaded girlfriend, a red ball or a red firetruck -- but you cannot have just "red."
Could there be a blob of "red" floating around in outer space? NO! it would have to be made from something.
RED is a word to describe a property of something else.
ENERGY is a word to describe a property of something else.
The term "Pure Energy" came from Spock on Star Trek. That is SciFi.
