A brief question: I am an armchair cosmologist - or maybe a "wannabe" cosmologist...it's a fine line. I am 47 years old with most of my career in software behind me but, without returning to college to become involved professionally in Astrophysics and Cosmology, I'd like to contribute to the field in some meaningful way. In Astronomy, for comparison, many amateur star-gazers use fairly sophisticated personally financed equipment to find exoplanets. Is there a similar method for amateur cosmologists to become involved (besides reading and learning all one can)? Any constructive suggestions will be appreciated!
