Gravity is not a force. Even Newton realized his equation for calling gravity a force was by faking his gravitational constant. Einstein's idea of it really being a distortion of space is still passing every test of it. Quite amazing really.
Which leads to everything passing through (particle) or propagating (wave) through space must also travel through the distortion of space. At the moment this appears to describe everything including dark matter and energy. Therefore everything is affected.
The fun thing at the moment is it is finally possible to see if anti-matter is also anti-gravity, negative mass to speak. Maybe results in a year or two. Going to be interesting.
