What does it mean to say that "6 tons of dark energy would be found within the radius of Pluto's orbit"?
- Does it mean that the dark energy is orbiting the solar system?
- Or does it mean a flow of dark energy through a sphere?
- Or does it refers to an energy in a particular system of inertia in the solar system?
Again on a mass–energy equivalence basis, the density of dark energy (6.91 × 10−27 kg/m3) is very low: in the solar system, it is estimated only 6 tons of dark energy would be found within the radius of Pluto's orbit. However, it comes to dominate the mass–energy of the universe because it is uniform across space. Wikipedia/Dark energy
