  2. 3 days ago · In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time. In Albert Einstein's 1905 treatment, the theory is presented as being based on just two postulates:

  3. 3 days ago · Hermann Minkowski (1864–1909) found that the theory of special relativity could be best understood as a four-dimensional space, since known as the Minkowski spacetime. In physics, Minkowski space (or Minkowski spacetime) ( / mɪŋˈkɔːfski, - ˈkɒf -/ [1]) is the main mathematical description of spacetime in the absence of gravitation.

  4. 5 days ago · Einstein's theory of general relativity is our best description of the universe at large scales, but a new observation that reports a "glitch" in gravity around ancient structures could force it...

  5. 4 days ago · Space-time, in physical science, single concept that recognizes the union of space and time, first proposed by the mathematician Hermann Minkowski in 1908 as a way to reformulate Albert Einstein’s special theory of relativity (1905). Learn more about space-time in this article.

  6. 2 days ago · Special relativity indicates that, for an observer in an inertial frame of reference, a clock that is moving relative to the observer will be measured to tick more slowly than a clock at rest in the observer's frame of reference. This is sometimes called special relativistic time dilation.

  7. 4 days ago · Abstract: A consistency condition of general relativity as an effective field theory in Minkowskian background uniquely fixes the value of the cosmological constant. In two-loop calculations, including the interaction of gravitons with matter fields, it has been shown that this value of the cosmological constant leads to vanishing vacuum energy ...
