Dark energy and Dark matter in simple terms:

Dark Energy: Simply put, the anti-gravitational effect observed in galaxies and their drift leads to the concept of a mysterious energy called dark energy. Dark energy is usually described by w ≡ P/ρ, where P and ρ denote its pressure and energy density. Dark Energy is un-massive, roughly 10¯²⁷ kg/m³. Dark energy causes repulsive gravity through negative internal pressure.

10¯²⁷ = 0.000000000000000000000000001

Dark Matter: In the simplest terms, the observed extra-gravitational effects on galaxies and their similar behavior, such as unaccounted rotation, lead to the idea of an invisible mass effect called dark matter.
