The vacuum energy density calculated from quantum field theory (energy contributions from electron fields, electromagnetic fields, Higgs field, and gluon fields in quantum chromodynamics) sums to an incredibly tiny number—0.0000...0001 with 120 zeros—yet because vacuum permeates all space, this tiny density dominates the universe's energy budget.

“somehow all of these vacuum energies add up to this okay they add up to 0.0000 with 120 zos one so the vacuum energy is Tiny... but because there's so much of it it fills all of space it overwhelms everything else”
