So the light we see from the lasers is emitted by atoms in space? I thought space was a vacuum? Or is it that the emitted light only comes from atoms in the atmosphere? So the further up we go, the dimmer becomes the emitted light.
Also, is there a way to determine how much blurring is happening from gravitational waves? In other words, if a ripple in spacetime washes across the space between us and a far away star, will the star become fuzzy like the schlieren distortion on a hot day here on earth? (faraway objects become ghostlike as heat from the hot ground alters the air density between observer and target)
