It has been observed in many cases; for example, in the fact that lots of objects move around other objects, in circles, ellipses, parabolas, or hyperbolas. This includes planets and asteroids moving around the Sun; moons moving around planets; the Sun and other stars moving around the center of the Galaxy; etc.
We observe planets, moons, comets, and artificial satellites and space probes moving in relation to the central body within their orbits exactly as we would expect them to move if the theory of universal gravitation is true. This evidence supports the theory of force at a distance due to universal gravitation, but doesn't prove it. It's still "only a theory", which can never be proven, but can be disproven in half-a-second if we ever see a situation where it's not working that way.
Gravity is caused by mass which is a property of physical matter. Even hydrogen, the lightest element in the Universe, has mass and is subject to gravity. An interesting question would be why the mass has gravity?
Never. Every object in the universe has gravity.
The center of gravity of a body is the point where the total weight of the body may be considered to act. It is the point around which the body's weight is evenly distributed in all directions, resulting in a balanced position. The center of gravity may not necessarily coincide with the geometric center of the body.
If you want to define total centre of gravity of a person, you must know:the mass of each body segmentsthe x, y and z coordinate of centre of gravity of each body segment (3D motion)

State the theme, back up your statement with evidence, then explain why it is universal.
The weight of a body depends on gravity(W=mg).Gravity gives us resistance against universal forces eg wind, which made building of house, driving of car, walking, flowing of water, droping of rain etc.

I'm guessing you mean a glacier.
The universal gravitational constant, which appears in Newton's Law of Universal Gravitation, can be used to calculate the gravitational attraction between any two masses, anywhere in the universe, not just here on Earth. Whereas the acceleration of gravity, g, is the specific acceleration caused by the planet Earth, at its surface where we live.
Gravity is the force of attraction between two masses, such as between the Earth and objects on its surface. It is responsible for the acceleration of objects towards the center of mass of a body, and is described by Newton's law of universal gravitation and Einstein's theory of general relativity.
When you are standing on, or in a body that has no gravity. That body will have to be quite small to have no gravity
Weight is the force of gravity on your body.
because the gravity is entering the body of ekonomiks....... because the gravity is entering the body of ekonomiks....... because the gravity is entering the body of ekonomiks.......
The three factors of gravity are mass, distance between objects, and the universal gravitational constant. Gravity is stronger between objects with larger masses and closer distances, and weaker with smaller masses and larger distances.
a growing body of evidence means that a lot of evidence is accumulating in anywhere.
