Close to large masses, time elapses more slowly. For example, on the surface of the Earth, time elapses a tiny bit slower than in outer space. In the case of more massive and dense objects, such as neutron stars, the effects are more drastic.Rotating masses produce additional effects.
What else can I help you with?
Gravitation is what according to the general theory of relativity?
The attraction between masses.
How celestial masses effect the passage of light?
According to the General Theory of Relativity, the path of light is bent near large masses. The more massive a celestial object is the more light is bent near it.
Does gravity accelerate all masses at the same rate?
Yes, according to the theory of general relativity, all masses are accelerated by gravity at the same rate regardless of their mass or composition. This principle is known as the equivalence principle.
How is masses classified?
Air masses are classified according to their maritime source regions and their latitude. Different air masses affect different parts of the world.
How is gravity generated?
Gravity is not generated. There are two main explanations of gravity, either general relativity, or an explanation which uses quantum mechanics. According to general relativity, gravity alteres spacetime. This causes a spacetime curvature, which is responsible for the fact that masses atracct one another. According to the other theory, it is the result of the exchanges of virtual gravitons. Since gravitons have not been observed yet, most physicists accept general relativity as the explanation. Other theories exist, but not enough evidence has been gathered so far.
How does the laws of gravity explains the relationship between mass and garvity?
Newton's law of gravitation doesn't really "explain" the relationship, it just states it. On the other hand, the General Theory of Relativity explains that masses distort space-time; this, in turn, affects the movement of other masses.
What does the theory of relatively do?
The theory of relativity, proposed by Albert Einstein, describes how the laws of physics are the same for all non-accelerating observers and explains the nature of gravity as a curvature of spacetime caused by mass and energy. It consists of two main branches: special relativity, which deals with objects moving at constant velocities, and general relativity, which incorporates gravity and acceleration.
What are the key differences between Newtonian gravity and Einstein's theory of gravity?
Newtonian gravity is based on the concept of a force acting between two objects based on their masses and distance, while Einstein's theory of gravity, known as general relativity, describes gravity as the curvature of spacetime caused by mass and energy. In general relativity, gravity is not a force but rather a result of the geometry of spacetime.
What is gravity controlled by?
Gravity is a fundamental force in nature that is determined by the mass and distance between objects. It is controlled by the distribution of mass in the universe, with larger masses creating stronger gravitational pulls. According to general relativity, gravity is the curvature of spacetime caused by mass and energy.
How are gravitational wave formed?
According to "General Relativity", gravitational waves should usually be formed when masses accelerate.See the "related links" below.For the second link you will need to scroll down the headings on the right of the page then click on "Gravity Waves". It's nice link, but there's perhaps too much detail. Just use what you think is helpful.Gravitational waves usually form whenever masses are accelerated.However waves are not formed in some cases, in particular if there is spherical symmetry.This is a difficult thing to explain. It involves predictions from Einstein's "General Theory of Relativity".You can try the "Gravitational wave" page on Wikipedia. Don't worry if you can't understand it all, but it may give you an idea of what is going on.Also, see "Sources and related links" below.
Where does the gravitational pull comes from?
The details are a bit complicated, and scientists are still trying to find part of the answer. But what you need to know, for most practical purposes, is that the gravitational force is related to masses. Masses attract one another. (According to the General Theory of Relativity, masses will distort space; this space distortion causes the attractive force on other masses. Scientists also believe that the force of gravity is transmitted through a hypothetical particle called a "graviton"; so far, they didn't manage to detect one, and it is expected to be very difficult to detect.)
How does the gravity affect other planets?
All masses attract one another. Do some reading about the general law of gravitation for more information.
