The same experimental data shows that time as measured by clocks in a gravitational field—proper time, to give the technical term—does not follow the rules of special relativity. In the language of spacetime geometry, it is not measured by the Minkowski metric. As in the Newtonian case, this is suggestive of a more general geometry.
Einstein considered this the finest description of the theory of relativity in any language.

In special relativity, energy is closely connected to momentum. In special relativity, just as space and time are different aspects of a more comprehensive entity called spacetime, energy and momentum are merely different aspects of a unified, four-dimensional quantity that physicists call four-momentum. In consequence, if energy is a source of ...
Galilean invariance or Galilean relativity states that the laws of motion are the same in all inertial frames of reference. Galileo Galilei first described this principle in 1632 in his Dialogue Concerning the Two Chief World Systems using the example of a ship travelling at constant velocity, without rocking, on a smooth sea; any observer below the deck would not be able to tell whether the ...

Howard Stein [5] and Steven F. Savitt [6] note that in relativity the present is a local concept that cannot be extended to global hyperplanes. Furthermore, N. David Mermin [ 7 ] states: That no inherent meaning can be assigned to the simultaneity of distant events is the single most important lesson to be learned from relativity.
