Quizplus · Accepted Answer

The discovery that the universe is expanding led to the development of the Big Bang theory, which states that the universe began as a singularity and has been expanding ever since. Hubble's Law is a key piece of evidence for the Big Bang theory, but it is not the theory itself. The Doppler effect and Einstein's laws are concepts related to physics and astronomy, but they are not directly related to the expansion of the universe.
