"Gravity, Weightlessness and Astronauts"
Speaker: Dr. Michael Ziegler
Our understanding of gravity has changed from Aristotle to Galileo, Newton, and then Einstein. Einstein's theories have correctly
predicted many recently measured phenomena, but cannot account for the shape of the Universe. We fill in the gaps in our understanding
of gravity with a cheat factor called dark matter to explain the existence and shape of nebulae, including the Milky Way. The heavy
elements were synthesized in supernovas and in gravity dependent phenomena such as the merger of neutron stars. We all realize that
the Earth could not exist without gravity, but orbital space flight has shown that our health depends on gravity as well. I will
review 40 years of research that shows how you got out of bed this morning without fainting, how weightlessness affects the health
of astronauts, what we currently do to allow astronauts to switch between gravity and weightlessness, and the challenges of long
term weightless flight to Mars and back.
Michael Ziegler (MD, U. of Chicago) aka 'Carole's spouse' began study of human responses to gravity at the National Institutes of
Health where he outfitted a Chevy Suburban as a mobile lab and tested people who fainted when they stood driving from Quebec Canada
to Atlanta Georgia with Carole's assistance. While in Galveston he studied Air Force pilots and pigs in a human centrifuge with forces
up to 9 G and astronauts after zero G. At UCSD he worked with the cardiovascular lab of NASA to test astronauts at Edwards AFB and Cape
Canaveral at landing. He tested identical twins after a month of head down bed rest while Director of the UCSD Clinical Research Center
and took part in the 'Year in Space' study of Scott Kelly and his identical twin Senator Mark Kelly. As Chair of the NASA Cardiovascular
Review Committee he summarized the challenges humans will face on a spaceflight to Mars.
