Cosmological constant theory of dark energy, illustration
Cosmological constant theory of dark energy, illustration. Dark energy is a relatively unknown quantity that is thought to be driving the universe's expansion. Here, it is shown as a constant, originating from empty space (inset at left) and exerting an outwards force. At right is a depiction of the universe originating in the Big Bang and expanding over time (straight arrow) as the galaxies formed. The curved arrows indicate an accelerating expansion forever. An alternative theory of dark matter is known as quintessence (see images C042/4588 to C042/4591). For this illustration without labels, see image C042/4585.
