A Slower Speed of Light is a freeware video game developed by MIT Game Lab that demonstrates the effects of special relativity by gradually slowing down the speed of light to a walking pace. The game runs on the Unity engine using its open-source OpenRelativity toolkit.
A kugelblitz (German: [ˈkuːɡl̩ˌblɪt͡s] ⓘ) is a theoretical astrophysical object predicted by general relativity.It is a concentration of heat, light or radiation so intense that its energy forms an event horizon and becomes self-trapped.
The interpretations of relativity used in the Rietdijk–Putnam argument and the Andromeda paradox are not universally accepted. 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.
Video simulation of the merger GW150914, showing spacetime distortion from gravity as the black holes orbit and merge. The theory of relativity usually encompasses two interrelated physics theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. [1]
Einstein hypothesized that the similar experiences of weightless observers and inertial observers in special relativity represented a fundamental property of gravity, and he made this the cornerstone of his theory of general relativity, formalized in his equivalence principle. Roughly speaking, the principle states that a person in a free ...
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) (/ m ɪ ŋ ˈ k ɔː f s k i,-ˈ k ɒ f-/ [1]) is the main mathematical description of spacetime in the absence of gravitation.
Reconciliation of general relativity with the laws of quantum physics remains a problem, however, as there is a lack of a self-consistent theory of quantum gravity. It is not yet known how gravity can be unified with the three non-gravitational forces: strong, weak and electromagnetic.
To derive the equations of special relativity, one must start with two other The laws of physics are invariant under transformations between inertial frames. In other words, the laws of physics will be the same whether you are testing them in a frame 'at rest', or a frame moving with a constant velocity relative to the 'rest' frame.
