In physics the Einstein-aether theory, also called aetheory, is the name coined in 2004 for a modification of general relativity that has a preferred reference frame and hence violates Lorentz invariance. These generally covariant theories describes a spacetime endowed with both a metric and a unit timelike vector field named the aether.
On Tulsa's Southwest Boulevard, between W. 23rd and W. 24th Streets there is a granite marker dedicated to Route 66 as the Will Rogers Highway which features an image of namesake Will Rogers together with information on the route from Michael Wallis, author of Route 66: The Mother Road; [58] and, at Howard Park just past W. 25th Street, three ...
U.S. Bicycle Route 66 (USBR 66) is a United States Bicycle Route that follows the former U.S. Route 66 (US 66) across the United States. The first section of the route, spanning 358 miles (576 km) between Baxter Springs, Kansas , and St. Louis, Missouri , was designated as USBR 66 in 2018.
The results of various experiments, including the Michelson–Morley experiment in 1887 (subsequently verified with more accurate and innovative experiments), led to the theory of special relativity, by showing that the aether did not exist. [20] Einstein's solution was to discard the notion of an aether and the absolute state of rest.
In Minkowski space-time every timelike and every lightlike (null) geodesic is a straight 'world line' that projects onto a straight-line geodesic of an equatorial cross section of a time slice of constant , as, for example, the one on which = and = /, the metric of which is that of euclidean two-space in polar coordinates [,], namely,
The National Historic Route 66 Federation was founded in 1995 for the purpose of saving the businesses, communities and roadbed of U.S. Route 66. The famous road carried travelers across much of the country from the day it was commissioned on November 11, 1926 through June 25, 1985 when it was decommissioned.
The Ellis drainhole is the earliest-known complete mathematical model of a traversable wormhole.It is a static, spherically symmetric solution of the Einstein vacuum field equations augmented by inclusion of a scalar field minimally coupled to the geometry of space-time with coupling polarity opposite to the orthodox polarity (negative instead of positive):
U.S. Route 66 (US 66, Route 66), the historic east–west US highway between Chicago, Illinois and Santa Monica, California, passed through one brief segment in the southeastern corner of Kansas. It entered the state south of Baxter Springs and continued north until it crossed Brush Creek, from where it turned east and left the state in Galena.
