Believe me
tommac you will be attacked mercilessly for trying to define space. It has no definition. If you say it has energy someone will say that it is a vacuum. If you say that it is empty someone else will say that it is brimming with energy. If you go half and half both sides will attack you.
Mainstream science doesn't know or want to know what space is otherwise it means not being to wear a person down who is trying to understand what space is. That is how science works.
However if you add properly define space to your resume as well as the study of gravity you may well receive a Nobel prize for answering an unanswerable (so far) question. You will also make a lot of people very upset because they will have to think of something else to try and confuse people with so their jobs stay secure.
A bit biased perhaps ... let me think, hmm. No I have been posting for a year and a half in the against the mainstream section and it holds water.
Good luck, cheers
