Does 'empty' space have mass which is displaced by matter?
That's fascinating! So, does the presence of matter in space displace this background energy?
Yes, that's right. Matter and energy can create regions of higher or lower energy density in the vacuum, which can cause the fabric of spacetime to curve and bend. This curvature affects the motion of other matter and energy in the vicinity, leading to phenomena like gravity and tidal forces.
