Description: This video explains dark matter and dark energy in less than 4 minutes. Dark matter makes up about 27% of the known Universe, and dark energy makes up the other 68%. We know very little about dark matter and dark energy - hence the word ‘dark’ being used to describe both. Dark matter is a form of matter that does not interact with light and so it is invisible to us. This video explains how we know it’s there and what we think makes up dark matter. Dark energy was discovered after experimental evidence showed that the expansion of the Universe was accelerating, rather than decelerating. What was causing this acceleration was dubbed dark energy. Dark energy, can be thought of as a property intrinsic to space and it’s behind the expanding Universe. ------------------------------------------------------------------------------------ OTHER VIDEOS YOU MAY LIKE: Theory of relativity explained in 7 mins - youtu.be/ttZCKAMpcAo Quantum Mechanics for Dummies - youtu.be/JP9KP-fwFhk Schrödinger's cat explained - youtu.be/OkVpMAbNOAo String theory made simple - youtu.be/Gc1OFo-TCz8 ------------------------------------------------------------------------------------ HARD STUFF MADE EASY - PHYSICS PLAYLIST: bit.ly/2S6honW ------------------------------------------------------------------------------------ BUY EDUCATIONAL EBOOKS - amzn.to/2T0Zb9W TITLES AVAILABLE String theory made simple Theory of relativity made simple Quantum Mechanics made simple The Fermi paradox ------------------------------------------------------------------------------------ SUPPORT THE CHANNEL ON PATREON - patreon.com/londoncitygirl #physics #darkmatter #darkenergy
