Since you are so familiar with the concept why not start from Earth

is in physics terms.

Art, you don't seem to understand that there is a quantum base medium
to which some other medium may or may not be added. The base medium
exists throughout all of universal space and is the only medium that
exists in otherwise empty space. Any other added medium, e.g. air or
water, is just mixed with that base medium. Please stop thinking with
a concrete brain.
