Final answer:
The Big Bang theory and the Oscillating Universe theory both represent different perspectives on the universe's origins. The Big Bang theory, which has much more empirical support and is more widely accepted by scientists, posits that the universe began from a hot, dense state and has been expanding ever since. The Oscillating Universe theory, lacking the same support, suggests the universe goes through infinite cycles of expansion (Big Bang) and contraction (Big Crunch).
Step-by-step explanation:
The Big Bang theory and the Oscillating Universe theory are two different concepts that attempt to explain the origins and future of the universe. The Big Bang theory suggests that the universe began from an extremely dense and hot state and it expands since then. Evidence for this theory includes the cosmic microwave background radiation, the abundance of light elements, and the expansion of the universe as observed by Hubble's Law.
On the other hand, the Oscillating Universe theory suggests that the universe goes through infinite cycles of expansion and contraction. Here, the universe oscillates between a Big Bang and a Big Crunch - it begins with a Big Bang, expands, contracts, leading to a Big Crunch, and then rebounds in a new Big Bang. However, this theory lacks empirical support and contradicts the second law of thermodynamics, which states that entropy in a closed system always increases.
Given the current evidence and cosmological understanding, the Big Bang theory is widely accepted among scientists as the more correct theory for the origin and history of the universe.
