Hi Everyone!
I need a bit of help with the following question please.
How does the energy density of the cosmological constant Uλ=ρλc^2 have the required SI units if λ=4∏Gρ/c^2
I know that the energy density of the cosmological constant (Uλ)is essentially dark energy and the SI units of energy density is Jm^-3. I also know that G is the gravity constant 6.67 x 10^-11 Nm^2kg^-2 and ρ is the energy density of matter. However, I am confused about the units.
Any help would be appreciated.
