Richard Conn Henry is an Academy Professor in the Zanvyl Krieger School of Arts & Sciences at
The Johns Hopkins University,
Director, Maryland Space Grant Consortium
Dr. Henry has more than two hundred publications, on topics including theoretical astrophysics, observational astronomy, radio astronomy, ultraviolet astronomy, and x-ray astronomy. For more information, please consult Henry's cv.
Dick Henry was graduated from Ridley College in 1957, and obtained a B.Sc. (1961) at University College, University of Toronto, where he won the Royal Astronomical Society of Canada Gold Medal. He obtained an M.A. in 1962, and a Ph.D. at Princeton University in 1967. Dick likes re-reading the old Nero Wolfe novels.
He has been a Research Associate at the Institute for Advanced Study, research physicist at the U. S. Naval Research Laboratory, and a Lecturer at the Latin American School of Space Research in Argentina. He has conducted astronomical investigations at Kitt Peak National Observatory in Arizona, and at both Las Campanas and Cerro Tololo Interamerican Observatories in Chile, and has participated in many rocket-astronomy experiments. Hey, so Dick is a rocket scientist. He has made observations using the Copernicus and IUE satellites and also the Hubble Space Telescope and the Mariner 9 spacecraft (at Mars), and was a co-investigator on Apollo 17 and also on the Apollo-Soyuz mission, and was a co-investigator on the Hopkins Ultraviolet Telescope. He was a Principal Investigator in the study of the lunar material, and he is the Principal Investigator for the Hopkins Ultraviolet Background Explorer (HUBE) , which was selected in 1996 April as a NASA MIDEX program alternate project. HUBE, in 2001, became a part of the highly-rated BEST round-three MIDEX mission. In 2003 HUBE was again proposed to NASA, this time as a SMEX candidate mission. But, sad to say, on 2003 November 4, the HUBE proposal was declined by NASA. Dick Henry has participated in eclipse expeditions to Quebec (in 1972), India (1980) and East Africa (1973 and 1980). He was a member of the group which discovered the first x-ray pulsar.
My hero is William Rowan Hamilton, who wrote the following unbelievable poem (Mathesis is the Greek goddess of science):

Dick Henry ...
|... with J.M. Overduin, M. Coplan, and K. Wilcomb, provides a roadmap to rotating and/or charged black holes .|
|... with his colleagues establishes yet more firmly the existence of mysterious UV radiation at high Galactic latitudes: "Components of the Diffuse Ultraviolet Radiation at High Latitudes," by M. S. Akshaya, Jayant Murthy, S. Ravichandran, R. C. Henry, and James Overduin, submitted to MNRAS, 2019. Some high latitude radiation is of course merely starlight scattered from dust, and so terminates at 911.8Å, BUT there is no reason for the "mystery source" not to extend below 911.8Å: and if it does so (and if is a feature of all galaxies) then it is surely the source of the reionization of the universe. But more importantly, the radiation itself must be due to SOMETHING ... and decay radiation of dark matter particles is the only available candidate ...|
... with his colleagues reaffirms the existence of mysterious UV radiation
at high galactic latitudes: "The Diffuse Radiation Field at High Galactic Latitudes,"
by M. S. Akshaya, Jayant Murthy, S. Ravichandran, R. C. Henry, and James Overduin, ApJ 858:101 (9pp), 2018 May 10.|
This radiation is NOT starlight scattered from dust!
|... draws attention to a vital paper by Tanvir et al. demonstrating (see their Figure 1) that we have a huge mystery on our hands: 99% of the hydrogen in the Universe is ionized, but we do not know what caused this ionization!|
...wonders if you know that 99% of your weight, when you step on the scales, is merely the kinetic energy of
the massless gluons that hold together all your protons and neutrons? The mass of your quarks and electrons is negligible!|
"Astrophysics with New Horizons: Making the Most of a Generational Opportunity,"

Sums it all up:|
General Relativity - natural! (curved spacetime is gravitation; OK!)
Quantum Mechanics - natural! (since observations are numbers, and simple symmetries are present; OK!)
Special Relativity: WHOA! HOLY SMOKES! A PYTHAGOREAN MINUS SIGN FOR TIME! The Universe knows ALGEBRA, which WE invented!
submitted to the ApJ, "Discovery of an Ionizing Radiation Field in the Universe",
by Richard Conn Henry, Jayant Murthy, and James Overduin|
And now take a look at the referee's report!
|... my PAPER How Einstein's Theory of Relativity Gives us E = mc2 and the Atomic Bomb at IAU 338 Gravitational Wave Astrophysics|
|... my POSTER How Einstein's Theory of Relativity Gives us E = mc2 and the Atomic Bomb at IAU 338 Gravitational Wave Astrophysics|
|... presented The Physics of our Universe at Multifrequency Sicily|
|... presented Ultraviolet Background Radiation from Beyond Pluto at Multifrequency Sicily|
|... asks you: Do you know the Pythagorean theorem (and high-school algebra)? If yes, and you would like to know WHY E = mc2  then !!-Click Me-!!|
... Do you know that the Gaussian curvature of spacetime near, at, and inside a Black Hole is zero ?   (a lot of physicists don't
know that! Yes, R = 0!)
(but of the components of the Riemann tensor Rαβγδ some 24 (out of 256) are non-zero in all those precincts, so, yes, spacetime IS non-flat!
So do keep your pets away from black holes!)
