Ether space-time & cosmology. Volume 3, Physical vacuum relativity and quantum physics [electronic resource] / Michael C. Duffy and Joseph Lévy, editors. Researches undertaken during the last 20 years have confirmed that space possesses physical properties even where it is devoid of ordinary. Aether theories in physics propose the existence of a medium, the aether a space-filling Quantum mechanics can be used to describe spacetime as being non-empty at extremely small scales, fluctuating and generating particle pairs that.

Despite the veil of equivalent terms, these names obviously refer to the Ether, a medium conceived in antiquity, which received much attention from Science ether spacetime and cosmology the 17th and early 20th centuries.

Today it is commonly understood throughout the academic community that Einstein excluded once and for all the ether from modern physics with his Special Theory of There is a widespread, unjustified assumption that ether is conceptually incompatible with Relativity, though Einstein developed an equivalent concept in the context ether spacetime and cosmology the General Theory and his later work.

We may add that Einstein? The aim of this first volume of papers ether spacetime and cosmology to examine the different paths by which the modern ether concept has been developed and to highlight the part it plays in major departments of 21st C physics.

Einstein's views on the aether Einstein sometimes used the word aether for the gravitational field within general relativitybut this terminology never gained widespread support.

According to the general theory of relativity space without aether 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 clocksnor therefore any ether spacetime and cosmology intervals in the physical sense.

But this aether may not be thought of as endowed with the quality characteristic of ponderable media, as consisting of parts which may be tracked through time. The idea of motion may not be applied to it.


It has been suggested by some such as Paul Dirac [7] that this quantum vacuum may be the equivalent in modern physics of a particulate aether. However, Dirac's aether hypothesis ether spacetime and cosmology motivated by his dissatisfaction with quantum electrodynamicsand it never gained support from the mainstream scientific community.

Aether theories

LaughlinNobel Laureate in Physics, endowed chair in physics, Stanford University, had this to say about ether in contemporary ether spacetime and cosmology physics: It is ironic that Einstein's most creative work, the general theory of relativity, should boil down to conceptualizing space as a medium when his original premise [in special relativity] was that no such medium existed [.

This is unfortunate because, stripped of these connotations, it rather ether spacetime and cosmology captures the way most physicists actually think about the vacuum. Relativity actually says nothing about the existence or nonexistence of matter pervading the universe, only that any such matter must have relativistic symmetry.


About the time relativity was becoming accepted, studies of radioactivity began showing that the empty vacuum of space had spectroscopic structure similar to that of ordinary quantum solids and fluids. Subsequent studies with large particle accelerators have now led us to understand that space is more like a piece of window ether spacetime and cosmology than ideal Newtonian emptiness.

It is filled with 'stuff' that is normally transparent but can be made visible by hitting it sufficiently hard to knock out a ether spacetime and cosmology.

The modern concept of the vacuum of space, confirmed every day by experiment, is a relativistic ether. But we do not call it this because it is taboo.
