What is the difference between Einstein's and Galileo's theories on relativity?
396173
The most obvious difference is that Galileo didn't have a theory on relativity.

I think you have the wrong idea.  The reconciliation between the theory of relativity and Newtonian physics is intrinsic to relativity itself.  When you consider the theory of relativity in the limit of small magnitude velocities, you recover classical mechanics.\n\nI think you mean to ask whether there has been a theory combining the standard model of particle physics with the general theory of relativity in a manner that predicts both, and the answer is no.

The dividing line is the use of the scientific method: observation, hypothysis and experiment.\n\nOne of the earliest was Galileo's experiment with falling bodies using the Tower of Pisa.  \n\nSee below.

In simpler words: special theory of relativity is just a special case of the general theory!\n\nGeneral theory of relativity deals with accelerated frames of reference. In other words when we have the 'acceleration not equal to zero' (e.g. gravitational acceleration), we use general theory. That is why this is mainly a 'theory of gravity'. One special case for this can easily be when acceleration = 0, and that is the case of special relativity! This is the basic difference between the two theories.\n\nThe other differences could be seen in the postulates of these two theories:\nSpecial theory of relativity postulates:\n1. A frame of reference moving with a constant velocity (i.e., no acceleration) with respect to an inertial frame, is also an inertial frame.\n2. Speed of light in vacuum remains constant in all inertial frames of reference.\n\nGeneral theory of relativity postulates:\n1. In an accelerated frame of reference (with respect to an inertial frame) the spacetime is warped. \nOr, Gravity warps spacetime. \n2. In an accelerated frame of reference (with respect to an inertial frame) the time is dilated. \nOr, Gravity dilates time.\n\n***\nInertial frames: A given region (or coordinate system) where Newton's laws are valid.\nSpacetime: The region in space and time.\nWarped: Distorted\nDilated: Slowed down.

Actually there is only theory of relativity: Einsteins general relativity. Special relativity explains only movement of bodies without acceleration. Most people belive that is everything relative but it isn't, there is an absolute spacetime. Einsteins relativity differs from Gallilean only in the fact that Gallilean take space and time to be separeted. Because of this important difference and the fact the speed of light is top speed comes the difference in calculation.

Nobody really knows.  Einstein's special theory of relativity posits gravity as a warp of space-time caused by the object's mass, but that only pushes the question one layer further down.  All we know for sure is that gravity exists, is pervasive, and can be important.

SIR elbert einsten because he is the great scietist of history. his theory of relativity is very exellent . when this world lost after some lack year then then this theory help us because in the future scientist go on new world in the space.these all thing posible when einstien theory says\nthat  for example a man  (age=18)who live on earth and one who(age=18) which goes in the universe with the speed of light after 50 years the age of man which who live on earth his age 65 year. and one which goes in the universe with speed of light his age is 35 years. tell me which scientist is genius.

I think Isaac Newton might have been as good, considering the limitations of his own time. Just remember he had to develop a new whole math to support his theories! (calculus) Then I dunno, but today Stephen Hawking? Have you read a brief history of time and the universe in a nutshell? I dunno, really, Einstein was GREAT!

One is incorrect and the other is correct.  The heliocentric model (or Copernican model) places the sun as the center of the solar system, with the planets revolving around it, which is correct.  \n\nThe geocentric model place the earth as the center of the solar system, with the planets and the sun rotating around it.  This is incorrect.  \n\nIn the 17th Century, the astronomer Galileo was branded a heretic and excommunicated from the Church for "daring" to challenge the Vatican's misguided belief (derived from a literal reading of the Bible) that the geocentric model was correct.  Science ultimately vindicated Galileo as correct, and the Church only issued a formal retraction of the excommunication of Galileo in this century.

Einstein's law of gravitation. It certainly looks nicer than Newton's :P

Impossible to compare. Both were the preeminent scientists of their generations. Einstein certainly knew a lot More, but he had the advantage of having Newton & many others shoulders to stand on.

Albert Einstein's theory of relativity, or simply relativity, refers specifically to two theories: special relativity and general relativity. As a field of study, relativity also includes metric theories of gravitation in which special relativity applies locally.\nThe term "relativity" was coined by Max Planck in 1908 to emphasize how special relativity (which at that time was the only relativity theory) uses the principle of relativity.\nAlbert Einstein's 1905 paper "On the Electrodynamics of Moving Bodies" introduced the special theory of relativity. Special relativity considers that observers in inertial reference frames, which are in uniform motion relative to one another, cannot perform any experiment to determine which one of them is "stationary". This is known as the principle of relativity. While this principle was not new to Albert Einstein's work, he found that including electromagnetism in this principle required a new formalism with many surprising consequences. In particular, it required the speed of light in a vacuum to be the same for all these observers, regardless of their motion or the motion of the source of the light.\nOne of the strengths of special relativity is that it can be derived from only two premises:\n·The laws of physics are the same in any inertial frame of reference. This means that the laws of physics observed by a hypothetical observer traveling with a relativistic particle must be the same as those observed by an observer who is stationary in the laboratory. \n·The speed of light in a vacuum is constant (specifically, 299,792,458 meters per second). \nGeneral relativity was developed by Einstein in the years 1911 - 1915. General relativity is a geometrical theory which postulates that the presence of matter "curves" spacetime, and this curvature affects the path of free particles (and even the path of light). It uses the mathematics of differential geometry and tensors in order to describe gravitation without the use of the force of gravity. This theory considers all observers to be equivalent, not only those moving with uniform speed.\nhttp://en.wikipedia.org/wiki/Theory_of_relativity

Simple..\n\nU know why Einstein is so-called the most genius man in the world.\nEveryone who didn't study modern physic would say. the famous equation E=mc^2 bought his fame. No Einstein is genius becoz of his work on relativity.\nOne of the postulates made by the Einstein is that gravitational force is the curvature of space-time. U probably don't realize the importance of that statement. \n\nBut here i want to stress on the word space-time. Before Einstein, every scientists treat space and time as 2 separate distinct. But Einstein is genius enough to find that space and time as single entity. \n\nthe universe is all about energy and gravitational force.\nPeople says the universe start when a dense material exploded. Thus the universe was born. Remember to treat space-time as single thing. So, when universe was born, so the space and time was expanded and run. when there is no time, there is no space. so when the universe perish, the time also disappears and so the space...\nBcoz there is no mass, lead to no gravitational force and lead to no space and time.\n\n\nSo, God is really Almighty. there is no start and there is no end to Him

Einstein's theories (never mind that they have checked out in reality) are incredible: space is curved; the shortest distance between two points is not a straight line; the universe is finite but unbounded; \n\nparallel lines eventually meet;

Well\nrelativity \n\nPhysical theory, introduced by Albert Einstein, that discards the concept of absolute motion and instead treats only relative motion between two systems or frames of reference. One consequence of the theory is that space and time are no longer viewed as separate, independent entities but rather are seen to form a four-dimensional continuum called space-time. Full comprehension of the mathematical formulation of the theory can be attained only through a study of certain branches of mathematics, e.g., tensor calculus. Both the special and general theories have been established and accepted into the structure of physics. Einstein also sought unsuccessfully for many years to incorporate the theory into a unified field theory valid also for subatomic and electromagnetic phenomena.\n\nEvolution from Classical Theory\n\nThe modern theory is an extension of the simpler Galilean or Newtonian concept of relativity, which holds that the laws of mechanics are the same in one system as in another system in uniform motion relative to it. Thus, it is impossible to detect the motion of a system by measurements made within the system, and such motion can be observed only in relation to other systems in uniform motion. The older concept of relativity assumes that space and time are correctly measured separately and regards them as absolute and independent realities. The system of relativity and mechanics of Galileo and Newton is perfectly self-consistent, but the addition of Maxwell's theory of electricity and magnetism to the system leads to fundamental theoretical difficulties related to the problem of absolute motion.

A.) In his General Theory of Relativity, Einstein developed a mathematical description of gravity—one that links space to time and mass to energy in a fundamentally geometrical fashion. In other words, mass(-energy) shapes space(-time) instead of acting like a “force” in the traditional Newtonian sense.  (Thus, in Newton’s description of gravity, one would say that all bodies exert an attractive gravitational force on one another. In Einstein’s conception, one would say that all bodies change the underlying geometry of space-time in a way that causes them to be attracted to one another.)  Thus, our best understanding of gravity is that it’s a fundamental property of space-time to be “warped” by the presence of mass(-energy). So gravity is simply a property of space-time, and most likely, it came into existence at the same time.  (One caveat: curvature or warping really only provides an analogy to what the equations tell us. If you want to imagine the effects of an object on its surrounding space-time, then you can think of it as changing the shape of space-time in its vicinity. The distortion is real—we can measure its effects—but the images that are often presented of flexible sheets of space-time with bowling balls or marbles rolling around on them, for example, simply present analogous situations.)\n\nB.)  Spinning is a common attribute of objects in the Universe because the way things form virtually always leaves them in rotation, and once things get started rotating, it’s hard to make them stop.  It’s not intuitively obvious, but if you take, say, a cloud of gas and dust collapsing to form a planetary system, then averaging all the random motions of the particles will leave you with some tiny element of rotation.  As the collapse takes place, any rotation will be magnified, so you end up with planets revolving around their parent stars, and planets themselves rotating on their axes.\n\nC.)  It’s doubtful that we’ll ever acquire much in the way of interstellar real estate, simply because the distances involved are so great.  Our best hope is to carry on radio communication with them, but even at the speed of light, it would take decades or centuries for radio signals to travel between us and the stars currently within our range of communication.\n\n\nRyan Wyatt\nRose Center for Earth & Space\nNew York, New York

begin our explanation of how Newton changed our understanding of the Universe by enumerating his Three Laws of Motion. \n\nNewton's First Law of Motion:\nI. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.  \n\nThis we recognize as essentially Galileo's concept of inertia, and this is often termed simply the "Law of Inertia". \n\nNewton's Second Law of Motion:\nII. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.  \n\nThis is the most powerful of Newton's three Laws, because it allows quantitative calculations of dynamics: how do velocities change when forces are applied. Notice the fundamental difference between Newton's 2nd Law and the dynamics of Aristotle: according to Newton, a force causes only a change in velocity (an acceleration); it does not maintain the velocity as Aristotle held. \n\nThis is sometimes summarized by saying that under Newton, F = ma, but under Aristotle F = mv, where v is the velocity. Thus, according to Aristotle there is only a velocity if there is a force, but according to Newton an object with a certain velocity maintains that velocity unless a force acts on it to cause an acceleration (that is, a change in the velocity). As we have noted earlier in conjunction with the discussion of Galileo, Aristotle's view seems to be more in accord with common sense, but that is because of a failure to appreciate the role played by frictional forces. Once account is taken of all forces acting in a given situation it is the dynamics of Galileo and Newton, not of Aristotle, that are found to be in accord with the observations. \n\nNewton's Third Law of Motion:\nIII. For every action there is an equal and opposite reaction.  \n\nThis law is exemplified by what happens if we step off a boat onto the bank of a lake: as we move in the direction of the shore, the boat tends to move in the opposite direction (leaving us facedown in the water, if we aren't careful!).
