Can Senior Citizens Still Explore Physics and Astronomy?

[kirkr]

How did you find PF?

I found Physics Forum by way of a Google search

I am retired and as a hobby I am exploring Einstein relativity, black holes and other facets of Astronomy and Physics. I received a B.A. in Physics and Mathematics from the University of Kansas way back in 1970. I have worked in the medical field, electronics and the environmental field.
