Hi all

Space id among the fundamental quantities in physics. Space refers to the relatively empty parts of the universe.

Space includes the outside area of the atmosphere of any celestial body. The boundary b/w space and earth's atmosphere is set as the Karman line.

is space really empty or do we just not see the things that are there, like the fabric of space time or string theory, dark matter, even the scientists don't understand. they have basic ideas but can't even prove those, that's why the conveniently call them theories.

could you expound your idea . please and thank you
