My subject here is gravity wells and their composition.

Gravity is a fascinating subject for me. The fact that we don’t quite understand one of the 4 fundamental forces is tantalizing. Some of this is due to antiquated assumptions which have garnered attention here. I think theThe best place to look for and understand gravity is right here on Earth. We have gravity AND the internet.

• ''Gravity can be explained by Newton’s law of universal gravitation, which states that the force of gravity is proportional to the product of the masses and inversely proportional to the square of the distance between them [/r²]. Gravity can also be understood by Einstein’s theory of general relativity, which states that gravity is a result of curvature in space-time caused by the mass of an object -www.uu.edu.''

It adds to the current state of confusion to primarily explain gravity with a 300-year-old formula that has nothing to do with time and which was completely supplanted by Einstein’s theory of general relativity and his explanation of 4-dimensional space-time. GR isn’t ‘another way’ that gravity can be understood, it’s THE way. Newtonian gravitational models can get you to Mars, but they don’t work when explaining gravity wells and their composition.

Here’s some basic scientific observations on gravity taken at known locations and altitudes on Earth.

Line 17:

''• Sea-level gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles.''

''• Gravity on the Earth's surface varies by around 0.7%, from 9.7639 m/s2 on the Nevado Huascarán mountain in Peru to 9.8337 m/s2 at the surface of the Arctic Ocean'''

The oblate flattening of the earth results in an equatorial bulge that sees the equator on average 21 kilometers further away from the center of this gravity well than the poles. So, thereThere is more mass underfoot at the equator, but less acceleration.

ItThis should beis a great clue to the yet to be revealed error that we can measure a higher acceleration at the poles where there is less physical matter underneath us than at the top of an equatorial mountain where there's kilometers more mass beneathbetween us onand ourthe radialcenter.

You cannot develop a contemporary theory of what gravitational acceleration looks like at the center of a gravity well without approaching it fromconsidering the standpoint ofrelative time.

''• Researchers have built an atomic clock that is more precise and accurate than any previous clock. For the first time, the clock can detect the effects of gravity predicted by the theory of general relativity at the microscopic scale. Hence, as we envision clocks like these being used around the country or world, their relative performance would be, for the first time, limited by Earth's gravitational effects.-nist.gov''

The most accurate way of measuring acceleration is with the use of identical atomic clocks measured at different distances from the center of a gravity well. Therefore, the first question that we should ask when solving for acceleration at the core is, "What time is it there?” We can’t send a clock to the core, but we have approached this topic in scientific literature.

Line 51:

As a thought experiment, consider the Earth, as it is with its stratified layers - a dense core with progressively less dense layers on top until you get to the crust and out into the stratified atmosphere. Now take the moon and shrink it down to the size of a softball. Retain the mass of the moon, but now it’s close to a neutron star in density. Hit pause and hold this ultra-dense object directly over the surface of the Earth

Being motionless, the Moon’s curved spacetime line will be a straight, stretched radial right to the center of the core.

Now start the simulation and let the moon fallgo. The deepest portion of Earth’s core and the center of the softball-sized moon will quickly displace the less dense materials between them and merge, with the little moon traveling the most distance and the core moving slightly for the merging. There will be some oscillation as the gravity well attains hydrostatic equilibrium again, but the dropped "softball moon" will quickly occupy the core, driving the Earth’s well ever deeper with its added mass. And due to its ultra-density, it will reside at the point of greatest acceleration - the center.

Earth’s surface acceleration is now over 10 m/s² due to being in a deeper gravity well without gaining any significant volume.

Line 59:

An acceleration tapering to zero at the core is a physics recipe for a hollow Earth rather than the home for the densest matter in the well.
