What is gravity? - NASA.
Current thinking is split between gravity having a quantum property and gravity simply being an effect in the way that mass warps space-time. Notwithstanding these ideas it could be that there is a quantum particle that contributes to the effect that matter is seen to always move towards the largest mass in its vicinity.
What Is Earth's Gravitational Force - A Plus Topper.
All positive charges spin in one direction while all negative charges spin in the opposite direction. It's all about spin and spin direction. If it is so that two counter rotating dielectric fields are required to achieve electro-gravitic flight, then from a scientific standpoint point that which we call gravity must be a dielectric field.

Physicist: Centrifugal force* due to the spinning of the Earth is certainly a measurable effect, but it's a small effect. While the spinning of the Earth doesn't directly affect gravity, it does off-set it a little. At the north and south poles objects weigh exactly what they should, and at the equator things weigh slightly less. The gravitational force is a long-range force, which exists between two particles, regardless of the medium that separates them. The gravitational force is directly proportional to the product of the mass of the two bodies ( m 1 × m 2). This means a larger mass will yield a larger force. The force obeys the inverse square law. Actually, you do land a little west of where you jumped. However, that distance is so miniscule for a human jumping that you don't notice it. The reason something projected straight up doesn't fall back onto the same spot is that its radius from the center of rotation increases as it gets higher.
Gravity-Powered Generator: Real Or Fake? - Hackaday.
The gravitational pull of the Earth DOES pull us down. So does gravity make the Earth spin? Short answer: No. Gravity and spin are totally separate. Longer answer: Some people wonder why we don't fly off the spinning Earth. The answer is, of course, that gravity holds us down. The force from the spinning is quite small. It's only 0.3% of gravity.
Newton's Law of Gravity - VEDANTU.
Gravitational Force. Gravitational force is a central force that depends only on the position of the test mass from the source mass and always acts along the line joining the centers of the two masses.. Newton’s Law of Gravitation: According to Newton’s law of gravitation, “Every particle in the universe attracts every other particle with a force whose magnitude is,. The energy transferred from gravitational tides is causing the Moon to move away at almost 4cm a year, and slowing the Earth's rotation! This fundamental force of gravity will help scientists model the interior of our Moon, Earth, and other planets, and measure the masses of distant stars and galaxies. The centrifugal force of any part or element of such a body is found by the equations given below, where R is the radius to the center of gravity of the part or element. In a flywheel rim, R is the mean radius of the rim because it is the radius to the center of gravity of a thin radial section.
Q: If the world were to stop spinning, would the people and everything.
The Short Answer: A gravitational wave is an invisible (yet incredibly fast) ripple in space. Gravitational waves travel at the speed of light (186,000 miles per second). These waves squeeze and stretch anything in their path as they pass by. A gravitational wave is an invisible (yet incredibly fast) ripple in space.
The Science of Spinning - Popular Science.
While the gravitational force upon the heavier bowling ball is greater than that upon the feather, the bowling ball's mass is also greater, offsetting the greater gravitational force. According to the Physician's Classroom, this rate of acceleration due to gravity is a constant 9.8 meters per second per second for all objects on Earth. In the United States, a dead goose weighing over 5kg fell from the sky. This poor goose shows us that flying birds can fall from the sky under the force of gravity, just like everything with mass. Using SpinCalculator, he estimated that a rotational velocity of 31 m/s would be sufficient for a system with a radius of around 100 meters (97.99 m to be exact; or 321.5 ft), producing the sensation of 1 g and rotating at a rate of about 3 rotations per minute. In layman's terms, 'real' artificial gravity could be achieved this way.
How The LIGO Observatory Detects Gravitational Waves - Hackaday.
Technically, rotation produces the same effect as gravity because it produces a force (called the centrifugal force) just like gravity produces a force. By adjusting certain parameters of a space station such as the radius and rotation rate, you can create a force on the outside walls that equals the force of gravity. The first method is quite simple, really: acceleration. Think of that initial burst of speed when traveling up in an elevator – you're forced to the floor. A spacecraft which is constantly accelerating would effectively create a gravitational pull in the direction opposite of the acceleration. So a ship that is gradually accelerating towards. The force depends on the masses and their separation, as shown in this equation F = Gm 1 m 2 /r² where G is a universal constant (not the same as g which changes from planet to planet), m 1 and m 2 are the two masses and r is the separation between their centres.

As early as the 1930s, scientists combined measurements of the rotational speed of galaxies with Newton's theory of gravity and determined that something was awry. The galaxies were spinning so fast that they could not be held together by the gravitational force of the observed matter and should have torn themselves apart.
Understanding gravity—warps and ripples in space and time.
As the solar nebula collapsed, the matter within began to spin faster under its own gravity. Due to conservation of angular momentum—the velocity of rotation of an object around a central axis.
Buildings with rotating sections on mars to simulate higher gravity.
Gravity is what makes things round as others said here as things pull towards a central point once an object has sufficient gravitational force it will make a round shape and again as people here tried to explain the spin (drill effect) try to distort the shape, the faster the spin the more oblate the shape. Boulder is about 1.6km above sea level, so in this formula, we would predict that \( g \) is smaller by about 0.05% due to our increased height. This is a very small difference, but not so small that it can't be measured! (Although there are other effects of similar size, including centrifugal force due to the fact that the Earth is spinning.).
Does spin affect gravity on a planet? - Quora.
Since the formation of the moon, Earth's spin has been slowing down by about 3.8 mph every 10 million years, mostly due to the moon's gravitational pull on our planet. So it's a lot more likely.
Our Motion Through Space Isn't A Vortex, But Something Far... - Forbes.
1) Within the Newtonian theory of gravitation: If a large sphere of uniform density is spinning around an axis, its gravitational field is the same as if it wouldn't be spinning at all. 2) However, in Einstein's general relativity theory the spinning causes a non-trivial effect, this goes under the name of Frame-dragging.
The Acceleration of Gravity - Physics Classroom.
Einstein tells us that gravity is actually just a fictitious force, too, but that doesn't stop physicists from treating it as real. The two fictitious forces we need to use here are the centrifugal force and the Coriolis force. The centrifugal is the easier to explain, and the more widely understood. "The rotation rate is so fast that the angular acceleration at the sphere surface is 1 billion times that of gravity on the Earth surface — it's amazing that the centrifugal forces [the forces. Newton's law of gravitation states that gravity pulls together. It is a force which pulls one object towards the center of another. It just so happens that, on the surface of the Earth, something like 99.999% of the gravitational pull you feel is that of the Earth, and the center of the earth is so far away that it simply feels like "down.".
