Question

Our confidence in the Big Bang theory stems from the application of well-known and well-tested laws of physics to the current state of the universe. These laws allow scientists to deduce the possible conditions the universe must have had at various points in its history to evolve into its present state. The Cosmic Microwave Background, a relic from the Big Bang, serves as evidence predicted and later discovered with specialized instruments. The stringent constraints imposed by the laws of physics, coupled with observational tools like telescopes, enable us to explore the universe's past and understand its evolution. While we can't directly observe the Big Bang, the indirect evidence and predictions based on fundamental physical laws provide a strong foundation for the theory.

What is the primary basis for the confidence in the Big Bang theory?

Options:
A. Direct observation of the Big Bang event
B. Theoretical predictions using well-tested laws of physics
C. Historical records of the universe's evolution
D. Reliance on eyewitness accounts

Answer 1

The primary basis for the confidence in the Big Bang theory is theoretical predictions using well-tested laws of physics.

Step-by-step explanation:

The primary basis for the confidence in the Big Bang theory is theoretical predictions using well-tested laws of physics. Scientists apply these laws to the current state of the universe and deduce the possible conditions it must have had to evolve into its present state. The Cosmic Microwave Background (CMB), which is a relic from the Big Bang, serves as evidence predicted and later discovered with specialized instruments.

Observation tools like telescopes, coupled with the stringent constraints imposed by the laws of physics, enable us to explore the universe's past and understand its evolution. Although we can't directly observe the Big Bang, the indirect evidence and predictions based on fundamental physical laws provide a strong foundation for the theory.
