You believe that Peers make science work by defining what is scientific and what is not.
No, once again, you have twisted everything anyone say, taking them out of context, because of lack of integrity and utter ignorance.
No, the authors of tested and scientific theories make “science”
The scientist (author) write the hypothesis must pass all 3 requirements:
- Falsifiability
- Scientific Method
- Peer Review
If the hypothesis successfully pass all 3 requirements, then it becomes a “candidate” of being a “scientific theory”.
I said “candidate”, because there may be more than 1 author of hypothesis or hypotheses.can compete against each other.
For instance, at the same time, there were 3 different theoretical cosmological hypotheses in the 1910s to 1930s, as example of competing hypotheses:
- Static Universe model or Static Model, by Albert Einstein, 1917 (Einstein added Cosmological Constant in 1918).
- Steady State model, by William Duncan MacMillan, in the 1920s.
- Expanding Universe models in the 1920s, by 3 theoretical physicists, who independently came up the very similar concepts, that would later be known as the Big Bang model:
- Alexander Friedmann (1922, Russian)
- Howard Percy Robertson (1924-25, American); the mathematician Arthur Geoffrey Walker (British) cowork with Robertson in the 1930s
- Georges Lemaître (1927), author of the Hypothesis Of The Primeval Atom.
I don’t know the details about MacMillan’s Steady State model, but the other scientists all used Einstein’s field equations from his General Relativity, to come up with their respective cosmological models.
As I said, Einstein added the Cosmological Constant to his field equations. Friedmann, Robertson-Walker & Lemaître have each independently added “metric” to Einstein’s field equations, as solutions to their respective Expanding Universe models, and Einstein’s field equations, became known Friedmann Equations when used with the Big Bang model.
The metric was known as the Friedmann metric, the Lemaître metric or the Robertson-Walker metric.
Both Robertson (1924-25) and Lemaître (1927) came up with the predictions of using the Redshift (also known as Cosmological Redshift), as measurements if the galaxies are moving away (redshift) or moving towards (blueshift), as means of determining if the universe was expanding or contracting. In 1929, Edwin Hubble made these observational discoveries of the Redshift.
This discovery of “redshift” led to Lemaître’s “Hubble’s Law”. The discovery also made astronomers and astrophysicists favoring Lemaître’s work, lose their interests in MacMillan’s Steady State model, and for Einstein publicly proclaiming the Cosmological Constant to be his biggest blunder.
But despite the popularity of Expanding Universe model, it remained a hypothesis, and both Expanding Universe model and Steady State model have new incarnations, where they compete against each other through the 1950s to 1964.
In 1948, George Gamow, Ralph Alpher & Robert Wilson worked together on the Expanding Universe model. Gamow was a former student of Alexander Friedmann, came up with new model the Hot Big Bang model, and they made 2 important predictions:
- Gamow & Alpher predicted the Big Bang Nucleosynthesis (BBN),
- Alpher & Wilson predicted the Cosmic Microwave Background Radiation (CMBR)
Both predictions are still relevant today, and they have both have to do with the formations of the early elements (atoms) in the young universe, before the formation of the stars.
On the other side, a newer and revised version of the Steady State model was formulated in 1948, by another team of 3 theoretical physicists: Hermann Bondi, Thomas Gold & Fred Hoyle.
It was Hoyle who derisively called the Expanding Universe model the Big Bang in 1949’s interview with BBC, and the name stuck.
Anyway, the Big Bang and Steady State model’s remained in “hypothesis” status, until 1964, with the accidental discovery of CMBR by Arno Penzias & Robert Wilson, when they were setting up radio antenna (as their radio telescope) at Bell Labs, in New Jersey. This discovery led to refuting Steady State model, and with the Big Bang model becoming scientific theory.
It took 42 year, and two discoveries of evidence to reach this status:
- Redshift in 1929
- Cosmic Microwave Background Radiation in 1964
Anyway, the credits go to both authors (Friedmann, Robertson & Lemaître in 1920s; Gamow, Alpher & Herman in 1948) and discoverers (Hubble in 1924; Penzias & Wilson in 1964), all of them, pioneers in the Big Bang model. They made the Big Bang theory possible, not the Peer Review.
As I said in my previous replies, Peer Review only reject pseudoscience concepts, works that have no testable evidence & data, and they only review and publish “well-tested” hypotheses, they don’t modify the hypotheses and they don’t take credits of the hypotheses that have achieved scientific theory status.
Any reviews where peers discover errors or anomalies in tests (eg evidence or experiments) that hypothesis author cannot explain, the hypothesis will also be rejected.
Credits only goes to those who are authors of the scientific theories with evidence & data to support their models, and to those who made important contributions to the theories.
