are you refering to dark matter?

Well, no, but, perhaps it is part of the problem.
I get into this a bit more in the "Photon Tunneling..." thread. The idea is to measure the compression of Space itself. They seek to measure point source Gravity Waves and are looking for Space Compression factor, at this distanceof about 1/10 of an atom. That feature, if proven, will open an entire new lines of reasoning about everything from Energy to Propulsion.
If we get 1/10 angstrom here, what is the compression at the source? What is the attenuation model/mechanism over these distances?
I posted some math about Space Density in the Math thread.
In my layman reasoning, I see Dark Matter as a form of matter that is also condensed from Spacetime, but is not as entirely condensed as what we call visible matter. It could be the Rosetta Stone for understanding how Space Resonance accounts for energy, matter, and time. The heralded
Grand Unification.

You know, in physics every time something is un-explainable they blame gravity. I feel like once gravity is figured out we will unraveled technologies beyond your wildest dreams. The huge advancements we see today is because we understand the atom and what you can do with it. Atoms may be the building blocks of life, but i bet gravity will be the fuel.

Matter and time are illusions. Matter is an illusion created from standing waves in space and time is an illusion created by conscientiousness.

because gravity is directly related to mass, it may be more of a 'perk' than an actual benefit. For instance, the gravity of the moon is substantially less, (83.3% less than earth's to be exact) so gravity there does not have the same effect. More math here:
Acceleration due to gravity is the acceleration of a freely falling body. Free falling means to drop vertically with no air resistance and an acceleration that doesn't change, or that is constant. The symbol for acceleration due to gravity is the letter g. The acceleration due to gravity, g is directed towards the center of whatever object gravity is draw towards, for example Earth, or any other planet.
An equation can be used to find the gravitational acceleration in different places. This equation is …
G is a constant, called the universal gravitational constant, which is equal to 6.67 × 10[SUP]-11[/SUP] N·m[SUP]2[/SUP]/kg[SUP]2[/SUP]. M is the mass of the object in which gravitational acceleration is being found. R is the radius of the object. There is a negative sign in front of the equation because objects in free fall always fall downwards toward the center of the object.
The acceleration due to gravity is 1.62 m/s[SUP]2[/SUP]. This is approximately 1/6 that of the acceleration due to gravity on Earth, 9.81 m/s[SUP]2[/SUP].
So naturally, to overide gravity you only need to devise a way to offset your mass. A heavy ship in the ocean should technically sink, but does not, due to displacement. Find a way to displace your mass and you have anti-gravity. Simple.

A little clarification. While Mr. Newton certainly was a smart fellow, he made a few errors along the way. According to Newton's first law, the velocity of a body (a state of rest or of uniform motion in a straight line) remains constant unless the body is compelled to change that state by external forces acted upon it. The problem with his first law is that there is no place in the universe that an object is free of external forces, due to gravity. So, his first law is...how you say..hot air!because gravity is directly related to mass, it may be more of a 'perk' than an actual benefit. For instance, the gravity of the moon is substantially less, (83.3% less than earth's to be exact) so gravity there does not have the same effect. More math here:

You made a statement that acceleration doesn't change, or is constant. Let me remind you, acceleration is the rate of change of velocity. In the absence of an opposing force (such as air resistance) to a free falling object, an object will continue to increase in velocity due to the acceleration of gravity. But...not only does the velocity increase, but so too does the acceleration increase, as the object is getting closer to the center of the earth as it falls towards the earth. The closer an object is to the earth the greater the acceleration due to gravity.
So, your statement, along with Mr. Newton's law is incorrect.

Seedling-
Some good observations, but may have forgot the following:
In fluid dynamics an object is moving at its terminal velocity if its speed is constant due to the restraining force exerted by the fluid through which it is moving. So fluids which are under an external force, (i.e, pressure) are only partially subject to gravitys pull as the pressure is the external driving force.
A free-falling object achieves its terminal velocity when the downward force of gravity (F[SUB]G[/SUB]) equals the upward force of drag (F[SUB]d[/SUB]). This causes the net force on the object to be zero, resulting in an acceleration of zero.[SUP][1])[/SUP]
As the object accelerates (usually downwards due to gravity), the drag force acting on the object increases, causing the acceleration to decrease. At a particular speed, the drag force produced will equal the object's weight
. At this point the object ceases to accelerate altogether and continues falling at a constant speed called terminal velocity (also called settling velocity). An object moving downward with greater than terminal velocity (for example because it was thrown downwards or it fell from a thinner part of the atmosphere or it changed shape) will slow down until it reaches terminal velocity.
Also don't forget, gravity is a coorelation to mass. If you are in deep space with no gravitational or external forces, you are at a constant: Either moving or stopped.
Newtonian mechanics has been superseded by special relativity, but it is still useful as an approximation when the speeds involved are much slower than the speed of light.

For the record- Newton and his buddies are still pretty smart, even if they are long dead.

Yeah, I know what terminal velocity is, but you weren't talking about terminal velocity when you said, "Free falling means to drop vertically with no air resistance and an acceleration that doesn't change, or that is constant."
No air resistance means no opposing force, so no terminal velocity is reached, the velocity just keeps increasing, and the rate at which the velocity increases is acceleration. But like I said earlier, as the objects get closer together the acceleration also increases, which means the velocity increases at a greater rate the closer the objects get to each other.
Don't get me started on SR. What a load of crap!

A little more food for thought about gravity. Some people already know this, but some don't, so I'll post it, because it is fun stuff!
Question: Negating air resistance, how much time does it take for a bowling ball to impact the ground when it's dropped from a height of 50 meters? How about 100 meters? Some would probably think that if it takes x amount of time to impact the ground when dropped from a known height of 50 meters, that it would take twice as much time to reach the ground when dropped from a height of 100 meters. Let's find out!!
So in order to find the time (t) of impact we need to know the initial velocity (u) which is zero in this case, the acceleration (a) which we'll use 9.8 m/s^2 for this example, and the distance (d), which we have 50 meters and 100 meters for two separate tests of impact time.
The bowling ball dropped from a height of 50 meters will impact the ground in 3.19 seconds.
The bowling ball dropped from a height of 100 meters will impact the ground in 4.52 seconds.
So, we see that doubling the height doesn't double the time. We also see that nowhere in the equation does it ask for the weight, or mass of the object. So in the absence of an opposing force (air resistance), a bowling ball and a marble should impact the ground in the same amount of time.
If we wanted to know the velocity of the bowling ball when it impacts the ground from the two heights we could use
...and we find that the bowling ball dropped from a height of 50 meters impacts the ground at a velocity of 31.30 m/s (70.02 MPH), and the bowling ball dropped from the height of 100 meters has a velocity of 44.27 m/s (99.03 MPH).
Fun stuff eh??

I'm watching this History show about Einstein. He did see that space is being effected by gravity, but, still it is thought of as a "curve." A "distortion" effect. I have always asked, disorted how, twisted and curved into what? It is only just now that we begin see this a compression effect. Space, here on Earth is not curved. We aren't at the bottom of a hole or well in space. Space is thicker here, more dense. The tinest amount of matter is actually a compression of Space. And it is dense enough to push Space aside.
So, it is a very basic shift in the understanding and perhaps coulfd lead to the control of gravity. To see it as compression is a very mechanical approach.
Don't need a fundamental force to unify and we can begin to think how to compression small space? How to have propulsion?
Space does not curve or distort, it is simply thick and dense around Matter. Perhaps Matter is Space in a weird way?
If the gravity waves can be measured, then space compression tech can be explored. Just got to think in the right direction.

Pfft. Dark matter/flow, et al, is just a manifestation of non-3-dimensional mass.

Well, I don't get the first acronynm, but can you say more about this? "just?" "manifestation?" I don't know what mass is, so I can't
really understand yet what you mean by non-3D mass or flow, for that matter.

There are more than three dimensions, fourth dimensional matter/gravity/mass affects our space.
Like a shadow is just a manifestation of an object passing between a light source and a surface, dark flow is a manifestation of the influence of "other" dimensions.
Can you imagine a 3 dimensional surface, on a 4 dimensional object?
