So I found this show today from the BBC, and it discusses if time travel is indeed possible, or if it is a pipe dream.

I had a huge long post done, but the page refreshed, and I lost everything. So instead, I will let people watch it (its about 49 minutes long), and then we can discuss it.
What I personally found the most interesting, is what was discussed at the end of the video (about 10 minutes left).
I think that part of the video raises some interesting scientific as well as theological type questions, which can be brought up once a few people have watched it.
It could be a fun and interesting discussion.
