WebNov 27, 2024 · Hubble's observations of an expanding universe lead to the Big Bang Theory. Explanation: Hubble's law shows the mathematical relationship between the distance from the earth and rate of expansion observed. The further from the earth the faster the object is moving away from the earth. WebBased on our current mathematical models, it appears our universe has an age, which is based on the start of the big bang. Our models cannot understand anything before the Big Bang. So we date it based on that. If new data leads to updated models that have a different age, we'll update it as needed - but based on the things we have observed.
