According to historical accounts of the meeting, Sir Arthur Eddington publicly dismantled Chandrasekhar’s mathematical proofs, labeling the concept of stellar collapse as “absurd” and “stellar buffoonery,” despite private recognition from peers like Paul Dirac and Wolfgang Pauli that Chandrasekhar’s physics were correct.
The 1935 Royal Astronomical Society Confrontation
On January 11, 1935, at Burlington House in London, Subrahmanyan Chandrasekhar presented his findings on the maximum mass a white dwarf could sustain before undergoing collapse. Chandrasekhar had secured the speaking slot through the encouragement of Sir Arthur Eddington, an eminent astronomer who had previously reviewed the work. However, following Chandrasekhar’s presentation, Eddington used his own allotted time to reject the mathematical foundations of the theory.
Eddington’s opposition centered on the physical impossibility of such a collapse. He famously argued, “I think there should be a law of Nature to prevent a star from behaving in this absurd way!” This dismissal continued beyond the London meeting; later, at Harvard, Eddington characterized the mass limit as “stellar buffoonery.” According to Chandrasekhar’s own recollections, Eddington even refused to recognize the validity of combining relativity with quantum mechanics in this context, stating he would not “regard the offspring of such a union as born in lawful wedlock.”
Did you know?
Despite Eddington’s public ridicule, physicists like Niels Bohr, Wolfgang Pauli, and Paul Dirac privately informed Chandrasekhar that his calculations were accurate. However, because these supporters were physicists rather than astronomers, they lacked the professional standing to effectively challenge Eddington within the astronomical community.
Institutional Influence and the Suppression of Dissent
Astronomer William McCrea, who attended the 1935 meeting, noted that Eddington’s arguments were “superficially satisfying,” leading many in the audience to accept his dismissal without further scrutiny. This dynamic left Chandrasekhar isolated, even when Eddington’s own arguments were logically inconsistent.
The tension reached a breaking point during a July 1939 dinner at Cambridge. According to Chandrasekhar, he, Eddington, Dirac, and physicist Maurice Pryce debated relativistic degeneracy. When Pryce walked Eddington through his own published argument, Eddington agreed it was accurate, yet when asked if he believed the logic, he could not recall the purpose of the argument. Upon being told that neither Dirac nor Pryce agreed with him, Eddington became visibly angry, pacing the room and declaring, “This matter is not for joking!” before spending the next hour attacking the very position he had just defended.
Scientific Reputation and Theoretical Rigor
Eddington’s resistance was rooted in his established theories regarding white dwarfs. He had long maintained that these stars consisted of a perfect gas devoid of degenerate matter. When rival astronomer E.A. Milne challenged this view, Eddington wrote that it was “absurd to pretend that I think there is the remotest chance of his being right.”
This temperament defined the opposition Chandrasekhar faced. When Chandrasekhar attempted to defend his work following a critical talk by Eddington in Paris, Bertrand Russell advised him against it. Consequently, Chandrasekhar was unable to offer a public rebuttal, effectively silencing his contribution to the field for years. By the time of their 1939 confrontation, the sustained hostility had left Chandrasekhar deeply disillusioned, questioning how much of Eddington’s broader scientific reputation rested on his flawed stance regarding relativistic degeneracy.
Frequently Asked Questions
- Why did Sir Arthur Eddington oppose the Chandrasekhar Limit? Eddington believed the physics of stellar collapse were “absurd” and inconsistent with his own theories on the nature of white dwarfs and stellar matter.
- Did other scientists support Chandrasekhar at the time? Yes. Physicists including Paul Dirac, Wolfgang Pauli, and Niels Bohr privately confirmed that Chandrasekhar’s mathematical and physical arguments were correct.
- How did Eddington’s influence affect the scientific community? Eddington’s status as a leading astronomer allowed him to marginalize Chandrasekhar’s work, causing many of his contemporaries to accept his dismissal rather than verify the underlying physics themselves.
