What is the ether in space?
ether or aether, in physics and astronomy, a hypothetical medium for transmitting light and heat (radiation), filling all unoccupied space; it is also called luminiferous ether. In Newtonian physics all waves are propagated through a medium, e.g., water waves through water, sound waves through air.
Is ether in the air?
Ether is immobile because it lacks the propulsive nature of air. Ether is subtle because it lacks the profound presence of the more obvious elements. Ether is also omnipresent. It is everywhere.
Is space Luminiferous aether?
The aether, the mysterious substance that filled space, was identified as the luminiferous medium. Therefore, to understand light, it was necessary to understand the special characteristics of the light medium.
What is space filled with?
Space is not empty. A point in outer space is filled with gas, dust, a wind of charged particles from the stars, light from stars, cosmic rays, radiation left over from the Big Bang, gravity, electric and magnetic fields, and neutrinos from nuclear reactions.
What did Einstein say about ether?
In special relativity Einstein rejecting the ether theory: ether do not exist.
Is ether and Sky same?
As nouns the difference between sky and ether is that sky is (obsolete) a cloud while ether is (organic compound|countable) a compound containing an oxygen atom bonded to two hydrocarbon groups.
Did Einstein believe in ether?
In special relativity Einstein rejecting the ether theory: ether do not exist. In this theory Einstein believe in Michelson-Morley experiments.
Is Luminiferous Aether real?
The timeline of luminiferous aether (light-bearing aether) or ether as a medium for propagating electromagnetic radiation begins in the 18th century. The aether was assumed to exist for much of the 19th century—until the Michelson–Morley experiment returned its famous null result.
Is space made of particles?
Outer space is not completely empty—it is a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays.
