unusual facts about speed of light



Impulse drive

In the fictional Star Trek universe, the impulse drive is the method of propulsion that starships and other spacecraft use when they are travelling below the speed of light.

Nukla

He can will himself into an invisible immaterial state and in said phantom form fire destructive bolts of pure "radiation-free" atomic energy from his hands and fly at the speed of light as well as quickly heal himself of any injuries received in his mortal flesh and blood form.

On Physical Lines of Force

-- which were ε0 and μ0 ?--> He obtained a value which was very close to the speed of light, as recently measured directly by Hippolyte Fizeau.

Variable speed of light

Paul Davies and collaborators have suggested that it is in principle possible to disentangle which of the dimensionful constants (the elementary charge, Planck's constant, and the speed of light) of which the fine-structure constant is composed is responsible for the variation.

Bell Telephone

A hypothetical device named after physicist John Bell which allows signals to be sent faster than the speed of light using quantum mechanics.

Carlos Cavazo

Born July 8, 1957, Cavazo is originally from Mexico City where his first band—of which his brother, Antonio Cavazo, was also a member—was called Speed of Light.

Château de Montlhéry

Thanks to its position, the keep was notably connected with the scientific experiments of Pierre Gassendi (measurement of the speed of sound), Claude Chappe (experiments with optical telegraphy in 1794) and Alfred Cornu (measurement of the speed of light in 1874).

Faster-than-light

The physicists Günter Nimtz and Alfons Stahlhofen, of the University of Cologne, claim to have violated relativity experimentally by transmitting photons faster than the speed of light.

The speed of light is a dimensional quantity and so, as has been emphasized in this context by João Magueijo, it cannot be measured.

Gravitoelectromagnetism

However, the pulsar is spinning at a quarter of the speed of light at the equator, and its radius is only three times more than its Schwarzschild radius.

Heechee

Faster-than-light spaceships that act by nullifying the mass of the ship and avoiding the implication of Einstein's Relativity Theory that states that an object becomes more massive as it approaches the speed of light.

João Magueijo

In 1998, Magueijo teamed with Andreas Albrecht to work on the varying speed of light (VSL) theory of cosmology, which proposes that the speed of light was much higher in the early universe, of 60 orders of magnitude faster than its present value.

Laplace's demon

The limit is based on the maximum entropy of the universe, the speed of light, and the minimum amount of time taken to move information across the Planck length, and the figure was shown to be about 10120 bits.

Michelson–Gale–Pearson experiment

It's also possible to define rotating frames in special relativity (Born coordinates), yet in those frames the speed of light is not constant in extended areas any more, thus also in this view a positive result must occur.

Modern searches for Lorentz violation

In the Futurama episode "Law and Oracle" (2011), Erwin Schrödinger is pulled over by cops for violating Lorentz invariance, by going 15 miles per hour over the speed of light.

Observable universe

According to the theory of cosmic inflation and its founder, Alan Guth, if it is assumed that inflation began about 10−37 seconds after the Big Bang, then with the plausible assumption that the size of the universe at this time was approximately equal to the speed of light times its age, that would suggest that at present the entire universe's size is at least 3x1023 times larger than the size of the observable universe.

Proper motion

Currently, the nearby star with the largest true velocity (relative to the Sun) is Wolf 424 which moves at 555 km/s (or 1/540 of the speed of light).
