Teoria da relatividade

It juxtaposes fundamental concepts space and time versus matter and motion which had previously been considered as entirely independent. Chandrasekhar also noted that Einstein's only guides in his search for an exact theory teoria relatividade geral the principle of equivalence and his sense that a proper description of gravity should be geometrical at its basis, so that there was an "element of revelation" in the manner in which Einstein arrived at his theory.

The first step teoria relatividade geral the realization that classical mechanics and Newton's law of gravity admit a geometric description.

The combination of this description with the laws of special relativity results in a heuristic derivation of general relativity. For example, teoria relatividade geral observer will see a ball fall the same way in a rocket left as it does on Earth rightprovided that the acceleration of the rocket is equal to 9.

Teoria relatividade geral the base of classical mechanics is the notion that a body 's motion can be described as a combination of free or inertial motion, and deviations from this free teoria relatividade geral. Such deviations are caused by external forces acting on a body in accordance with Newton's second law of motionwhich states that the net force acting on a body is equal to that body's inertial mass multiplied by its acceleration.


In modern parlance, their paths are geodesicsstraight world lines in curved spacetime. However, there is an ambiguity once gravity comes into play.

This suggests the definition of a new class of inertial motion, namely that of objects in free fall under the influence of gravity. This new class of preferred motions, too, defines a geometry of space and time—in mathematical teoria relatividade geral, it is the teoria relatividade geral motion associated with a specific connection which depends on the gradient of the gravitational potential.

Space, in this construction, still has the ordinary Euclidean geometry.

However, spacetime as a whole is more complicated. As can be shown using simple thought experiments following the free-fall trajectories of different test particles, the result of transporting spacetime vectors that can denote a particle's velocity time-like vectors will vary with the particle's trajectory; mathematically speaking, the Newtonian connection teoria relatividade geral not integrable.

From this, one can deduce that spacetime is curved.

The teoria relatividade geral Newton—Cartan theory is a geometric formulation of Newtonian gravity using only covariant concepts, i. The differences between the two become significant when dealing with speeds approaching the speed of lightand with high-energy phenomena.

They are defined by the set of light cones see image.


The light-cones define a causal structure: These sets are observer-independent. In mathematical terms, this defines a conformal structure [30] or conformal geometry. Special relativity is defined in the absence of gravity, so for practical teoria relatividade geral, it is a suitable model whenever gravity can be neglected.

Bringing gravity into play, and assuming the universality of free fall, an analogous reasoning as in the previous section applies: Instead there are approximate inertial frames moving teoria relatividade geral freely falling particles.
