“Aristotle taught that there was an immovable ‘entelechy’ in the universe that moves everything and the thought was its main attribute. I am also convinced that the whole universe is unified in both material and spiritual sense. Out there in the universe there is a nucleus that gives us all the power, all the inspiration; it draws us to itself eternally, I feel its mightiness and values it transmits throughout the universe; thus keeping it in harmony. I have not breached the secret of that core, still I am aware of its existence, and when wanting to give it any material attribute I imagine LIGHT, and when trying to conceive it spiritually I imagine BEAUTY and COMPASSION. The one who carries that belief inside feels strong, finds joy in his work, for he experiences himself as a single tone in the universal harmony.”

“It is true that many scientific minds envisaged the theory of a gaseous ether, but it was rejected again and again because in such a medium longitudinal waves would be propagated with infinite velocity. Lord Kelvin conceived the so-called contractile ether, possessing properties which would result in a finite velocity of longitudinal waves. In 1885, however, an academic dissertation was published by Prof. De Volson Wood, an American, at a Hoboken institution, which dealt with a gaseous ether in which the elasticity, density and specific heat were determined with rare academic elegance. But, so far, everything pertaining to the subject was purely theoretical.”

What, then, can light be if it is not a transverse vibration? That was the question he asked himself and set out to find the answer.

“I consider this extremely important. Light cannot be anything else but a longitudinal disturbance in the ether, involving alternate compressions and rarefactions. In other words, light can be nothing else than a sound wave in the ether.

“This appears clearly if it is first realized that, there being no Maxwellian ether, there can be no transverse oscillation in the medium.”

The Newtonian theory is in error, because it fails entirely in not being able to explain how a small candle can project particles with the same speed as the blazing sun, which has an immensely higher temperature. We have made sure by experiment that light propagates with the same velocity irrespective of the character of the source. Such constancy of velocity can only be explained by assuming that it is dependent solely on the physical properties of the medium, especially density and elastic force.”
