Because scientists were so puzzled by the phenomenon of energy through the vacuum of space, what

did they call the material they assumed existed between the Earth and the Sun?
A. Ether
B. Sciosphere
C. Plasma
D. Albedo

my answer is a.

Ether is the best answer, but I assure you it did not come about because of being puzzled about the phenomenon of energy transmission. The concept of ether was created because folks had no idea what a vacumn was, especially a vacumn void created by gravity. Gravity was not recognized as being associated with the mass then, later Newton discovered that relationship about 2000 years after the Greeks invented the "aether" concept.

Your text stinks, me thinks, if it teachs such nonsense as in the last two questions.

Thanks I agree with you!!1 It is so confusing for me!!!

Correct answer: A. Ether

Explanation:
Scientists in the past hypothesized the existence of a material called "ether" to explain the transmission of energy through the vacuum of space. The concept of ether was proposed in the 17th century as a hypothetical medium that filled the empty space between celestial bodies. It was thought to be responsible for propagating light waves and other forms of electromagnetic radiation. However, subsequent scientific discoveries, such as the Michelson-Morley experiment, undermined the ether hypothesis, leading to the development of the theory of relativity and the understanding that space is not filled with a material medium like ether.
