Bill Nye Explains The Big Bang Discovery
TDC・1 minute read
Edwin Hubble and Fred Hoy's observations led to the theory of the Big Bang, with Arno Penzias and Robert Wilson's discovery of cosmic background radiation providing evidence that confirmed this theory. The COBE spacecraft further validated these findings, solidifying the concept of an expanding universe originating from a single point.
Insights
- Edwin Hubble's observation of stars moving apart led to the theory of an expanding universe, while Fred Hoy's Big Bang concept proposed that all matter was once closely packed before expanding, eventually validated through radio astronomy.
- Arno Penzias and Robert Wilson's discovery of cosmic background radiation in New Jersey, supported by the COBE spacecraft, provided concrete evidence for the Big Bang theory, aligning with astronomers' predictions and solidifying the understanding of the universe's origins.

Discovery of Universe Expansion and Cosmic Background Radiation
- Edwin Hubble, situated at Mount Wilson in California, observed that stars were moving apart, indicating an expansion of the universe. Another astronomer, Fred Hoy, suggested the concept of a Big Bang, theorizing that all matter was once together before expanding, a notion initially met with skepticism but later confirmed through radio astronomy.
- Arno Penzias and Robert Wilson, at a site in Basking Ridge, New Jersey, discovered the cosmic background radiation, a remnant of the Big Bang predicted by astronomers. This finding was validated by the Cosmic Background Explorer (COBE) spacecraft, aligning precisely with astronomers' calculations.
