When we use the term ether today, we mean specifically diethyl ether or perhaps the generic class of compounds of which it is a member.
In the early part of the 19th century, the term "ether" was applied to any volatile including muriatic ether (ethyl chloride) and acetic ether (ethyl acetate).
At this juncture it was clear that ether and water were formed by the action of sub-stoichiometric amounts of sulfuric acid and that sulfovinic acid was formed as an intermediate in the reaction.

It is plausible, however, that what we have in Ether’s record (and it is important to stress that it is Ether’s record) is a backwards understanding the kingship of the Jaredites being attached to the earliest founding fathers.
The kings (and their attendant social hierarchy) were one of the ultimate reasons for the demise of the Nephites, and Moroni would have see the story of the Jaredites as similar.
While it is possible that this information was clearly represented on Ether’s plates, it is also quite plausible that it has been manipulated into a form that makes it appear so remarkably parallel to the Mosiah story that Moroni clearly knew.

The ether of the general theory of relativity is transmuted conceptually into the ether of Lorentz if we substitute constants for the functions of space which describe the former, disregarding the causes which condition its state.
According to the general theory of relativity space without ether is unthinkable; for in such space there not only would be no propagation of light, but also no possibility of existence for standards of space and time (measuring-rods and clocks), nor therefore any space-time intervals in the physical sense.

 Introduction   (Site not responding. Last check: 2007-10-22)
The idea behind their experiment was that as the earth moves through space it would at times be moving with the ether and at other times against the ether.
Thus, physicists reasoned that as the earth moved through the ether, the speed at which light moved in one direction would be different from the speed in another direction.
As a result, scientists gradually discarded the idea of the ether (since it couldn't be detected), and they began to accept the idea that the speed of light is the same in all directions.
