You seem to be the resident "expert" on astronomy
Well, my first degree is in astronomy (astrophysics) but I then moved into the more mathematical aspects of cosmology/theoretical physics (quantum gravity, string theory, etc)
Where do we stand scientifically with space exploration and our knowledge of space and it's origins?
Wow, that covers quite a bit
I would say that over the past 100 years, our knowledge of the Universe at the largest scales, and the smallest, has grown by an almost unimaginable factor. That said, the more we discover, the more we realise how much more there still is to discover...
If you look back through the Big Bang and Cosmology forum, you will see many of the threads I have been involved in, and the myriad of subjects that I have tried to explain (similarly for Son Goku, who is our other resident theoretical physicist.) You may see a topic there you'd like to discuss, or perhaps you are most interested in the usual creationist hotspot of the Big Bang, and "atheistic" ideas of something-from-nothing. We haven't done that in a while, and it would be refreshing to discuss it with creationists who seem to have open ears
