Gravity is a force of attraction that exists between all objects with mass. It is what keeps us grounded on Earth and affects the motion of celestial bodies in space, such as stars and planets. The strength of gravity depends on the mass of the objects and the distance between them.
Humans do not defy gravity by nature. They are subject to the force of gravity just like all other objects on Earth. However, humans can overcome gravity temporarily through methods like jumping, flying in aircraft, or floating in water, but the force of gravity always exists.
Dilute gravity refers to a situation where the effects of gravity are weak, such as in regions where the gravitational field is low compared to standard conditions on Earth. This can happen at extreme distances from massive objects like planets or stars, where the gravitational pull is significantly reduced.
No, gases do not have an opposite gravity. Gravity affects all matter, including gases, by pulling them towards the center of mass of a celestial body like a planet. So, gases are also subject to gravity just like solids and liquids.
An object's center of gravity always lies at the point where its weight can be considered to act. For a symmetrical object like a sphere, the center of gravity is at its geometric center. In irregularly shaped objects, the center of gravity may not necessarily be located at the geometric center.
The gravity range of celestial bodies in our solar system varies widely, from the intense gravity of massive planets like Jupiter to the much weaker gravity of smaller bodies like asteroids and comets. The gravitational pull of a celestial body is determined by its mass and size.
