???  What Is Gravity  ???


  • Does Gravity Push, or does Gravity Pull ?

  • Newton and Einstein didn't Know !

  • They Spoke Out, and Told Us So !

  • So does Gravity Push, or does Gravity Pull ?


*In 1667, Newton mathematically deduced the nature of gravity, demonstrating that the same force that pulls an apple down to earth also keeps the moon in its orbit and accounts for the revolutions of the planets.

... Newton openly stated that he had no idea what gravity actually was.  All he knew was that it had to be caused by something.

The idea that a body may act on another through the vacuum of space over huge distances "without the mediation of anything else ... is to me so great an absurdity that I believe no man can ever fall into it  Gravity must be caused ... but whether this agent be material or immaterial I have left to the consideration of my reader."


Consider ...

    Which Things Push,

      and Which Things Pull,

        in our Universe.

as above   —   so below

 
 

We know, objects near the earth Experience an Accelerating Force.

The force averages 32 feet per second, per second.

 
 
If an analogy works,   Use it !

But, when your analogy no longer explains good, repeated observations, it is time to move along.
 
If a dynamic ether could be shown, could it be the causal force of gravity ?

  • An Attractive Force! — Who did the experiment that "Proves This"!!!

  • Weightlessness! — If the Space Shuttle Lost Its Weight, it wouldn't stay in orbit !   ===> No Weight; No Inertia !   ===> No Forward Momentum ! ===> Fall Down, Go Boom !!!

  • Zero Gravity / Micro-Gravity  —  Gravity is ALWAYS THERE !!!
    Just because You Think You Don't Feel It, doesn't mean its not there !!!
 
 

The Space Shuttle Stays in Orbit because ...

It is in a Balanced State of "Free Fall".

For every foot it falls toward the earth because of the accelerating force of gravity,   Inertia,   moving in a straight line, moves the Space Shuttle one foot further away from the earth. That is why it needs to be moving so fast to stay in orbit.   And, the faster it travels, the higher the orbit needs to be inorder to maintain stability.   {Do The Math — Know the Science }

ASSAULT ON GRAVITY

New investigations into gravity throw sizable doubt on Einstein's Theory of Gravity.

 
 
Faithful readers of SCIENCE and MATH WEEKLY know a great deal about the big new experimental push against the mysteries of gravity. They also know that there was practically no serious experimentation between Newton and the present day. Results have come sooner than anyone expected. Last January Dr. R.H. Dicke of Princeton rocked the world of physics with experimental evidence that Einstein's theory of gravity (General Relativity) did not correct an effect long observed in the behavior of the orbit of Mercury.

Mercury moves quickly around the sun in an elliptical path, like a horse running around a racetrack. This race track (orbit) is also slowly swinging around in space. It is this slow turning, only about 1,000" of arc per century, that causes all the trouble. We can attribute the swing to the pulls of the planets, but when the homework is all in, we can account for only a part of the 1,000" ' There is a big fat 43.1' not accounted for.

Einstein's gravity theory was hailed and accepted when it exactly accounted for the 43.1". But now Dicke has found that the sun is not spherical It has a slight bulge around the equator. This bulge also helps move the racetrack around. The unexplained error is now about 39 of arc. A small amount, perhaps, but larger than the limits of our observations and computing abilities.

A new theory of gravity must now be sought. Readers of SCIENCE and MATH WEEKLY will know that there are many alternate theories available. The problem is to choose the right one.

Dr. Hill of Wesleyan University (Conn.) is now conducting a similar experiment to see how much the sun's mass deflects starlight passing near the solar body. The results (due in a year or two) may also rock our confidence in a part of Einstein's picture of gravity.

Despite statements in almost all books, attempts to measure this gravitational deflection of starlight by photographing stars near the sun during a total eclipse have been failures. The effors of measurement have been as large as the effect sought. It is improper to say the eclipse pictures provide any proof for Einstein.


Experimental Results Dispute Newton's Gravitation Constant

A Russian physicist at the Massachusetts Institute of Technology (MIT) has announced experimental data that may topple one of science's most cherished dogmas that Newton's constant of gravitation, famously symbolized by a large "G", remains constant wherever, whenever and however it is measured.

Mikhail Gershteyn, a visiting scientist at the MIT Plasma Science and Fusion Center and his colleagues have successfully and experimentally demonstrated that the well-known force of gravitation between two test bodies varies with their orientation in space, relative to a system of distant stars.

The idea that forces on bodies may vary relative to the orientation of distant stars has a powerful historical precedent in "Mach's Principle", a term Einstein coined in 1918 for the theory that eventually led him to his biggest breakthrough general relativity.

Swing a bucket of water at the end of rope and centrifugal forces pull it up and away. These forces result from the combined gravitational pull of all the distant stars and planets, Austrian physicist Ernst Mach wrote.

Any change in the orientation of heavenly bodies would affect forces on matter everywhere, so powerful is their combined effect. The idea that G may change with respect to the way a body is positioned relative to the rest of the universe is simply an example of Mach's adage: matter out there affects forces right here.

Newton's gravitational constant G changes with the orientation of test masses by at least 0.054 per cent, according to Gershteyn's experiments, a remarkable and unprecedented finding that has landed his paper on the subject in the journal Gravitation and Cosmology.

"The existence of such an effect requires simply a radically new theory of gravitation, because the magnitude of this effect dwarfs any of Einstein's corrections to Newtonian gravity." Isaac Newton first described G in 1687 as a fundamental component of his universal law of gravity.

Two masses, Newton said, attract one another with a force proportional to their mass that falls off rapidly as the bodies move farther and farther apart. Albert Einstein later used G in his own field equations that fine–tuned Newton's original laws.

The constant G puts precise limits on gravity's attractive force and appears in equations that describe any gravitational field, whether the field is between planets, stars, galaxies, microscopic particles or rays of light.

Centuries of measurement have firmly fixed the value of G at 6.673 X 10–11 cubic meters per kilogram per square second.

If G varies under any circumstances, scientists would have to rewrite virtually every physical law and a long–accepted feature of the Universe isotropy, or the condition that a body's physical properties are independent of its orientation in space.

Gershteyn and his co–workers lay an extraordinary and very interesting claim which if proven true would change our view of the universe, Lev Tsimring, a research physicist with the Institute for Nonlinear Science at the University of California San Diego, told UPI.

The experiment, he said, would seek to detect gravitational anisotropy — the condition that the attractive force between bodies would vary with respect to their spatial orientation, not their separating distance.

Los Alamos National Laboratory scientist Michael Nieto, took very careful measurements of some satellite orbits and found they can't be described by gravity calculations, and can't be explained away by systematic problems either.
