Dark and dark energy. d. What is it?. Dark energy a mysterious, force that is pulling galaxies apart. It makes up about 70 percent of the universe.
Dark Energy. Distance. How far away something is gets complicated at high z How far it is now? How far it was then? How far light travelled? How distant it looks? Let’s call r the distance to an object now It used to be closer, because everything was closer, by factor of a / a 0
