Hace 3 días · 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:
Hace 3 días · 1956 – John Lighton Synge publishes the first relativity text emphasizing spacetime diagrams and geometrical methods. 1957 – Felix A. E. Pirani uses Petrov classification to understand gravitational radiation. 1957 – Richard Feynman introduces his sticky bead argument.
Hace 3 días · A decade before Hubble made his observations, a number of physicists and mathematicians had established a consistent theory of an expanding universe by using Einstein field equations of general relativity.
Hace 5 días · General Relativity and Gravitation is a journal devoted to all theoretical and experimental aspects of modern gravitational physics. Founded in 1970, it ...
Hace 2 días · The objective of these meetings is to elicit exchange among scientists that may deepen our understanding of spacetime structures as well as to review the status of ongoing experiments aimed at testing Einstein's theory of gravitation either from the ground or from space.
Hace 4 días · Time’s reality is questioned by both Einstein’s relativity and McTaggart’s logical arguments, which present different but inconclusive methods to understand time. Modern physics suggests time may be an illusion. Einstein’s theory of relativity, for example, suggests the universe is a static, four-dimensional block that contains all of ...
Hace 3 días · The exact Friedman solution to the field equations of General Relativity (GR) describing an homogeneous and isotropic universe together with its linear and higher-order perturbations are the theoretical roots of the current standard model of cosmology. However, despite its global successes, this standard model currently faces a number of tensions and anomalies, which occur mostly from a ...
