Galilean Relativity
Relativity can be described using space-time diagrams . Contrary to popular opinion, Einstein did not invent relativity. Galileo preceded him. Aristotle had proposed that moving objects (on the Earth) had a natural tendency to slow down and stop. This is shown in the space-time diagram below.
Note the curved worldline above. This shows a variable velocity, or an acceleration . Galileo objected to Aristotle's hypothesis, and asked what happened to an object moving on a moving ship.
Now it is still moving in its final state. Galileo proposed that it is only relative velocities that matter. Thus a space-time diagram can be transformed by painting it on the side of a deck of cards, and then skewing the deck to one side but keeping the edges along a straight line:
Straight worldlines (unaccelerated particles) remain straight in this process. Thus Newton's First Law is preserved, and non-accelerated worldlines are special. This Galilean transformation does not affect the time. Thus two observers moving with respect to each other can still agree on the time, and thus the distance between two objects, which is the difference in their positions measured at equal times, can be defined. This allowed Newton to describe an inverse square law for gravity. But Galilean transformations do not preserve velocity. Thus the statement "The speed limit is 70 mph" does not make sense but don't try this in court. According to relativity, this must be re-expressed as "The magnitude of the relative velocity between your car and the pavement must be less than 70 mph". Relative velocities are OK.

    Special Relativity
    Newton's laws of motion give us a complete description of the behavior moving objects at low speeds. The laws are different at speeds reached by the particles at SLAC. Einstein's Special Theory of Relativity describes the motion of particles moving at close to the speed of light. In fact, it gives the correct laws of motion for any particle. This doesn't mean Newton was wrong, his equations are contained within the relativistic equations. Newton's "laws" provide a very good approximate form, valid when v is much less than c . For particles moving at slow speeds (very much less than the speed of light), the differences between Einstein's laws of motion and those derived by Newton are tiny. That's why relativity doesn't play a large role in everyday life. Einstein's theory supersedes Newton's, but Newton's theory provides a very good approximation for objects moving at everyday speeds. Einstein's theory is now very well established as the correct description of motion of relativistic objects, that is those traveling at a significant fraction of the speed of light.

In 1916 Einstein expanded his Special Theory to include the effect of gravitation on the shape of space and the flow of time. This theory, referred to as the General Theory of Relativity , proposed that matter causes space to curve.

Embedding Diagrams
Picture a bowling ball on a stretched rubber sheet.

The large ball will cause a deformation in the sheet's surface. A baseball dropped onto the sheet will roll toward the bowling ball. Einstein theorized that smaller masses travel toward larger masses not because they are "attracted" by a mysterious force, but because the smaller objects travel through space that is warped by the larger object. Physicists illustrate this idea using embedding diagrams Contrary to appearances, an embedding diagram does not depict the three-dimensional "space" of our everyday experience. Rather it shows how a 2D slice through familiar 3D space is curved downwards when embedded in flattened hyperspace. We cannot fully envision this hyperspace; it contains seven dimensions, including one for time! Flattening it to 3D allows us to represent the curvature. Embedding diagrams can help us visualize the implications of Einstein's General Theory of Relativity.

E = mc which reveals the equivalence of mass and energy.
When Einstein applied his theory to gravitational fields, he derived the "curved space-time continuum" which depicts the dimensions of space and time as a two-dimensional surface where massive objects create valleys and dips in the surface. This aspect of relativity explained the phenomena of light bending around the sun, predicted black holes as well as the Cosmic Microwave Background Radiation (CMB) a discovery rendering fundamental anomalies in the classic Steady-State hypothesis. For his work on relativity, the photoelectric effect and blackbody radiation, Einstein received the Nobel Prize in 1921. Theory of Relativity The Basics
Physicists usually dichotomize the Theory of Relativity into two parts.
  • The first is the Special Theory of Relativity, which essentially deals with the question of whether rest and motion are relative or absolute, and with the consequences of Einsteins conjecture that they are relative.
    The second is the General Theory of Relativity, which primarily applies to particles as they accelerate, particularly due to gravitation, and acts as a radical revision of Newtons theory, predicting important new results for fast-moving and/or very massive bodies. The General Theory of Relativity correctly reproduces all validated predictions of Newtons theory, but expands on our understanding of some of the key principles. Newtonian physics had previously hypothesised that gravity operated through empty space, but the theory lacked explanatory power as far as how the distance and mass of a given object could be transmitted through space. General relativity irons out this paradox, for it shows that objects continue to move in a straight line in space-time, but we observe the motion as acceleration because of the curved nature of space-time.

Relativity Trail First edition owners, click here Contact Synopsis ... Infamous Twin Paradox The back cover: Einstein's special theory of relativity, in absolute terms - In special relativity, one makes his measures using clocks, measuring rods and light beams. Einstein's two postulates of special relativity, as used in his treatment, address only what measurements one shall arrive at. In Relativity Trail , you'll be introduced to the absolute form of these postulates, which addresses the absolute nature of things, particularly - clocks, rods and light beams themselves. Upon the absolute form of these postulates depends our ability to understand what is generating the mutual effects of relative uniform motion and, identically, what has created the time differential between reunited clocks. In Relativity Trail , we faithfully diagram Einstein's special theory against an absolute frame of reference which is intrinsic to the evolving structure of our universe. In so doing, Relativity Trail provides its readers with a clear description of:
  • what time keeping is why time keeping and lengths of rods vary with motion why all inertial frames are effectively equivalent why there is no clock paradox why mass varies with motion why E = mc
and much more.

    17. Relativistic Velocities
    Here is the formula for adding velocities in special relativity when motion occurs in a single direction.
    [Physics FAQ] Updated by Terence Tao 1997.
    Original by Philip Gibbs 1996.
    How Do You Add Velocities in Special Relativity?
    Suppose an object A is moving with a velocity v relative to an object B , and B is moving with a velocity u (in the same direction) relative to an object C . What is the velocity of A relative to C v u -> A -> B C w -> In non-relativistic mechanics the velocities are simply added and the answer is that A is moving with a velocity w = u+v relative to C . But in special relativity the velocities must be combined using the formula u + v w = - 1 + uv/c If u and v are both small compared to the speed of light c , then the answer is approximately the same as the non-relativistic theory. In the limit where u is equal to c (because C is a massless particle moving to the left at the speed of light), the sum gives c . This confirms that anything going at the speed of light does so in all reference frames. This change in the velocity addition formula is not due to making measurements without taking into account time it takes light to travel or the Doppler effect. It is what is observed after such effects have been accounted for and is an effect of special relativity which cannot be accounted for with newtonian mechanics.

It was able to explain some pressing theoretical and experimental issues in the physics of the late 19th century involving light and electrodynamics , such as the failure of the 1887 Michelson–Morley experiment , which aimed to measure differences in the relative speed of light due to the Earth's motion through the hypothetical luminiferous aether , which was then considered to be the medium of propagation of electromagnetic waves such as light.
