The innermost stable circular orbit (often called the ISCO) is the smallest marginally stable circular orbit in which a test particle can stably orbit a massive object in general relativity. [1] The location of the ISCO, the ISCO-radius ( r i s c o {\displaystyle r_{\mathrm {isco} }} ), depends on the mass and angular momentum (spin) of the ...
An experiment to test the theory of relativity cannot assume the theory is true, and therefore needs some other framework of assumptions that are wider than those of relativity. For example, a test theory may have a different postulate about light concerning one-way speed of light vs. two-way speed of light, it may have a preferred frame of ...
Their results are consistent with the predictions of special relativity. Collections of various tests were given by Jakob Laub, [1] Zhang, [2] Mattingly, [3] Clifford Will, [4] and Roberts/Schleif. [5] Special relativity is restricted to flat spacetime, i.e., to all phenomena without significant influence of gravitation.
Special relativity is a theory of the structure of spacetime. It was introduced in Einstein's 1905 paper "On the Electrodynamics of Moving Bodies" (for the contributions of many other physicists and mathematicians, see History of special relativity). Special relativity is based on two postulates which are contradictory in classical mechanics:
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 paper, On the Electrodynamics of Moving Bodies , the theory is presented as being based on just two postulates : [ p 1 ] [ 1 ] [ 2 ]
However, in Bailey et al. (1977) the particles were subject to a transverse acceleration of up to ~10 18 g. Since the result was the same, it was shown that acceleration has no impact on time dilation. [28] In addition, Roos et al. (1980) measured the decay of Sigma baryons, which were subject to a longitudinal acceleration between 0.5 and 5.0 ...
An elegant theory, special relativity yielded its own consequences, [31] such as the equivalence of mass and energy transforming into one another and the resolution of the paradox that an excitation of the electromagnetic field could be viewed in one reference frame as electricity, but in another as magnetism.

Bell's spaceship paradox is a thought experiment in special relativity. It was first described by E. Dewan and M. Beran in 1959 [1] but became more widely known after John Stewart Bell elaborated the idea further in 1976. [2] A delicate thread hangs between two spaceships initially at rest in the inertial frame S.
