We currently believe about two thirds of our universe consists of Dark Energy, which is slowly tearing it apart. Which observations provided the first evidence for Dark Energy?

• Distant galaxies were closer than expected

• Distant galaxies were fuzzier than expected

• Distant galaxies were greener than expected

• Distant galaxies were further away than expected

Big Bang Theory

• (cosmology) the theory that the universe originated 20 billion years ago from the cataclysmic explosion of a small mass of matter at extremely high density and temperature

• Collection of stars, gases, and planets around a dense center called a nucleus which they rotate around

• A force of attraction between objects that is due to their masses.

• The distance light travels in a year, 6 trillion miles
