What is aether meaning?

Aether, also known as ether, is a term used in ancient and medieval science to describe a hypothetical substance believed to fill the upper regions of space. It was thought to be a pure and intangible element that was the essence of the heavenly bodies, including the stars and planets. Aether was considered to be the medium through which light and other electromagnetic waves traveled.

Later, the concept of aether evolved, and it was believed to be the medium that transmitted gravitational forces as well. However, with the advancement of modern physics, the concept of aether has largely been replaced by theories of electromagnetic fields and the curvature of space-time. Today, aether remains an important concept in philosophy, poetry, and literature.
