The Big Bang Theory explains the universe's origin from a huge explosion 13.7 billion years ago, supported by evidence like cosmic microwave background radiation and redshift showing expansion. Arno Penzias and Robert Wilson discovered cosmic microwave radiation by eliminating noise, revealing remnants of the Big Bang's heat, while redshift confirms the universe's expansion as distant galaxies move away from us.
Insights
- Arno Penzias and Robert Wilson's discovery of cosmic microwave background radiation provided crucial evidence supporting the Big Bang Theory by revealing the universe's remnants of heat from the initial explosion, reinforcing the theory's validity.
- Redshift, observed in distant galaxies moving away from us, serves as additional confirmation of the Big Bang Theory, showcasing the ongoing expansion of the universe and solidifying the scientific understanding of its origins.

Universe's Origin: Big Bang Theory Explained
- The Big Bang Theory posits that the universe originated from a massive explosion approximately 13.7 billion years ago and has been expanding since. Evidence supporting this theory includes cosmic microwave background radiation and redshift, which demonstrate the universe's expansion.
- Arno Penzias and Robert Wilson's discovery of cosmic microwave background radiation involved eliminating all sources of noise with a microwave receiver, leading to the realization that the microwaves were remnants of the Big Bang's heat. Redshift further supports the Big Bang Theory by showing that the universe is expanding, as distant galaxies exhibit a redshift indicating their movement away from us.
