Activity: Dark matter and dark energy
This image shows the Milky Way galaxy as viewed from Earth. Here we'll conclude Astrophysics by explaining how the presence of dark matter is predicted by the rotation of galaxies and deriving the critical density formula. We'll also get into the details on dark energy and interpret the anisotropies in the CMB. Galaxies in Wonderland Rotating galaxies The Pinwheel galaxy (European Space Agency & NASA) When you did...
