Einstein's derivation of the gravitational field equations was delayed because of the hole argument which he created in 1913. [1] However the problem was not as given in the section above. By 1912, the time Einstein started what he called his "struggle with the meaning of the coordinates", [ 2 ] he already knew to search for tensorial equations ...
As its name suggests, it was a sketch of a theory, less elegant and more difficult than general relativity, with the equations of motion supplemented by additional gauge fixing conditions. After more than two years of intensive work, Einstein realized that the hole argument was mistaken [247] and abandoned the theory in November 1915.
The issue of whether covariance is a real restriction and if so in what sense appears in various contributions to the philosophical debate concerning Einstein's "hole argument." This argument initially had led Einstein in 1913 for a time to reject generally covariant theories, because a region of space/time without forces would undermine ...
The researchers said they detected gravitational waves coming from two black holes - extraordinarily dense objects whose existence also was foreseen by Einstein - that orbited one another ...
At the urging of Tullio Levi-Civita, Einstein began by exploring the use of general covariance (which is essentially the use of curvature tensors) to create a gravitational theory. However, in 1913 Einstein abandoned that approach, arguing that it is inconsistent based on the "hole argument".
For the first time ever, scientists have seen the light from behind a
According to Axe, the research he provides with his book disproves Darwin's theory of evolution, revealing "a gaping hole has been at its center from the beginning." Click through 10 books that ...
Einstein's argument that falling light acquires energy To show that the equivalence principle necessarily implies the gravitation of energy, Einstein considered a light source S 2 {\displaystyle S_{2}} separated along the z -axis by a distance h {\displaystyle h} above a receiver S 1 {\displaystyle S_{1}} in a homogeneous gravitational field ...
