What else can I help you with?
Is there another name of relativity?
There are two. There is Special relativity, the one that says you can't go faster than the speed of light. Then there is General relativity, the one that describes gravity as bending space rather than as a Newtonian attraction between objects.
Is the force of gravity or E and M subject to relativity?
Yes. Everything is subject to relativity. We know that electormagnetism (EM) is subject to relativity because we see light from distant stars and galaxies bent by the gravity of intervening objects (see http://en.wikipedia.org/wiki/Gravitational_lens). Gravity is subject to relativity because it is an essential element of General Relativity. GR says that gravity is the curvature of spacetime.
What explanation does general relativity provide for the phenomenon of gravity?
General relativity explains gravity as the result of the curvature of spacetime caused by the presence of mass and energy. Objects with mass create a "dip" in spacetime, causing other objects to move towards them due to the curvature of this space.
What explanation does general relativity provide for gravity and how does it differ from classical theories of gravity?
General relativity explains gravity as the result of the curvature of spacetime caused by mass and energy. This differs from classical theories of gravity, such as Newton's law of universal gravitation, which describe gravity as a force acting between objects with mass.
How does general relativity explain the phenomenon of gravity?
General relativity explains gravity as the result of the curvature of spacetime caused by the presence of mass and energy. Objects with mass create a "dent" in spacetime, and other objects are pulled towards this dent, which we perceive as gravity.
What does a guy mean when he says to a girl he fancies he would bend over backwards for her?
When a guy says that he would bend over backward for a girl he fancies, it means that he would do anything to keep her happy.
Does the concept of gravity as an independent force completely disappear from our reasoning?
Gravity, to be a field force, would require a particle to transmit it. To date, all attempts to detect gravitons have failed. Either they don't exist, or they are very inconvenient to detect. General Relativity provides us a way of thinking about gravity without needing to assume the existence of elusive gravitons. General Relativity says that mass tells space how to bend, and then space tells mass how to move.
How do you sell items to Mr Hubert?
To resell your objects there should be a button under where the objects are being sold that says resell your objects.
Why planets revolves around the sun?
Einstein revised our idea of planetary orbits in his theory of relativity, which says that planets orbit the sun because of the sun's distortion of space. This distortion causes space to bend. The planets move along this bend. Think of a Bowling ball placed on a mattress. The ball causes a circular dent in the mattress. If you shoot a marble at the ball, the marble will move around the bowling ball in a circle along the path of the indentation. In the same way, the planets revolve along the indentation the sun makes in space.
What is the theory of relitivity?
This question is confusing/mixing-up two different scientific theories, and should be worded something like:"What is Darwin's theory of evolution?"'The Origin of Species' (1859), a book by Charles Darwin explaining his theory of evolution provoked great controversy: by casting doubt on the historical accuracy of the biblical accounts of Creation it caused many believers to question their faith in Christianity.Another scientist, Albert Einstein, proposed a "General theory of relativity" that has nothing to do with Darwin's theory!Technically correct attribution of theories aside, Darwin's theory of 'relativity' is that all living things are relatives!
Why do heavier objects fall more slowly than lighter objects?
They don't. The basic physics behind the situation says that all objects fall together, regardless of their mass, weight, race, color, creed, national origin, or political affiliation. In the reral world, especially on Earth, we occasionally see things falling at different rates.
When does time freeze?
When an object is travelling at the speed of light in a vacuum, relativity theory says that time stops for that object. Relativity theory also says that it is not possible for any object with a non-zero mass to accelerate to that speed. So, except in the trivial case of massless particles (which, in a vacuum, already travel at the speed of light), time does not ever freeze.
