The fact that after centuries of science discounting such stuff as precognition, prophecy and other means of predicting the future, always claiming that the future is fluid, we now have science telling us that the future is not fluid. THAT bothers me, when it comes from the scientists. (Myself, I never truly believed in free will, it is nothing but an illusion; I've believed that all actions we might take, are indeed taken, but only one version of our consciousness is ever aware of those actions; this plays into the whole Parallel Worlds theory).

Of course, cosmologists also talk about quantum entanglement, which is pretty "spooky" IMO (yes pun intended if you know what Einstein said about entanglement), and almost (I said ALMOST) gives credence to concepts of astrology (that distant stellar bodies can have an effect on us here on Earth).

For me, it isn't so much the fact that our future seems to be fixed, but that science is now coming to that conclusion, when previously that sort of concept was the province of theologians and philosophers.
