The problem you may be having is there is no separate thing called 'space'. There is only 'spacetime'.

Spacetime would like to have a word with you.

Here we go again... "scientists would look at the ripples in the fabric of space and time". Am I the only one who finds this expression very confusing? What fabric? There is no fabric. Space and time are coordinates. They do not exist physically at all. There cannot be a fabric of space and time.

More things should be described as "propagating through spacetime"

If time isn't real, but space is - how real is spacetime?

Space is just time rotated 90 degrees

space and time are the same thing

How does it "touch on relativity of space and time"?
