Hello and I hope you have found what you are looking for. This website sill explain what Dr. Robbert Goddard has contributed to space travel and what black holes are all about. You can look at the recommended websites too.
I also have blogs for black holes and Dr. Goddard. (These blogs can found by clicking on the links here or on the topic's page where a link can be found there as well e.g. Black hole's blog link can be found on page Black Holes)What I am doing with them is taking a piece of information on each of those topics and starting a debate. I invite you to make a comment and argue against me or defend my thinking. Just to get you involved. If you don't want to, that's fine. I thought this would be fun.
All I ask is that if you use my page, please site me in your resources (a how-to of that is on How to site this website).
