Describe the "big bang theory"

• Matter that emits no light at any wavelength.

• A huge collection of stars.

• is that the world began with a bang. And since then our world is expanding.

• The shift to a different wavelength. Because the universe is expanding, light from galaxies is red-shifted. The more distant a galaxy is, the faster is moves away from Earth.
