Black Holes and Animal Testing

I think the group that talked about black holes was extremely interesting. It's frightening to be playing with this black box of a machine, possibly being predicted to even destroy the world someday!? I thought said a lot about our society and the world that we live in- so much money put into technology that would either potentially save our world because it could be a controlled and its energy could be harvested OR it could be turned to complete power and possibly such our world into its own black hole in one second. I believe this black box needs to be better explored before they continue to play around with it.
I also thought the group who did the animal testing was really interesting... Descartes- "I think therefore I am"... therefore we are human and we exist. And it is cruel to test on humans for harmful experimentations. What really made me curious about this project was how do we know animals aren't thinking? where do we draw the lines at thinking vs. being able to communicate? The idea of existing and being part of reality instead of just living as a plant or animal are really tricky lines that are in need of being drawn.
