He has an A.B. in Astronomy from Harvard University (1954), and Ph.D. in Astronomy from the California Institute of Technology (1958).
On Redshift quantization
Described by astronomer William M. Napier in 2006 as "controversial claims", he notes:
- "Anomalous redshift" claims have appeared in the literature for about 30 years now and are associated with a few astronomers such as H.Arp, the Burbridges and W.G. Tifft"
In a 1993 article in Discover magazine article on Tifft, popular science writer Dava Sobel noted:
- "The editors of the Astrophysical Journal grudgingly published his first quantized-redshift paper in 1976, but they announced in an unusual disclaimer that they couldn't endorse the idea (although they also couldn't find anything wrong with the underlying observations)"
- " isn't necessarily claiming that the universe isn't expanding, he says -- only that if it is, some other process is affecting redshifts as well. His basic idea is that redshift could be an intrinsic property of the galaxy and not merely something done to its light as the light travels through space."
Astrophysical Journal had written:
- "Editor's note:- The referees of this paper neither could find obvious errors with the analysis nor felt that they could enthusiastically endorse publication. The subject matter is interesting and perhaps important. A more complete assessment of the analysis is beyond the role normally expects of referees"
