Neither dark energy nor dark matter is visible, however. So how do astronomers know they exist? They see how they interact with the rest of the universe. Dark energy is believed to cause the acceleration of the expansion of the universe and dark matter causes something called strong gravitational lensing, or the bending of light caused by its massive gravity.

Unknown title out at the stars, what you see — and what astronomers can see using complex telescopes — accounts for just five per cent of what is contained in the universe. Dark matter makes up roughly 27 per cent more, and dark energy another 68 per cent. <span>Neither dark energy nor dark matter is visible, however. So how do astronomers know they exist?
