University of New South Wales (UNSW) physicists are studying a distant star where gravity is more than 30,000 times greater than on Earth to test their controversial theory that α (alpha) — also known as the fine-structure constant — is not a constant. “If alpha [the fine-structure constant] were bigger than it really is, we should not be able to distinguish matter from ether [the vacuum, nothingness], and our task to disentangle the natural laws would be hopelessly difficult. The fact however that alpha has just its value 1/137 is certainly no chance but itself a law of nature. It is clear that the explanation of this number must be the central problem of natural philosophy.” — Max Born, cited by A.I. Miller in Deciphering the Cosmic Number: The Strange Friendship of Wolfgang Pauli and Carl Jung, W.W. Norton & Co, 2009 In 1999, a team led by John K. Webb of the University of New South Wales claimed the first detection of a variation in α Now Dr. Julian Berengut of the UNSW School of Physics and his international team are using the Hubble Space Telescope to measure the strength of α more accurately on a white dwarf star. “A white dwarf star was chosen for our study because it has been predicted that exotic scalar-energy fields could significant alter alpha in places where gravity is very strong,” said Berengut. science.unsw.edu.au/news/study-white-dwarf-star-throws-light-constant-nature
