GameRager: Never said science never paid off...just that it takes awhile and right now Hawking's theories aren't really helping the common man that much. They may someday but not now.
Without science, there is no scientific gain, and there is no ground for new applied science, meaning technology will fall behind.
If you postpone Hawking's research, you postpone what it may blossom into - for sake of argument, let's say it will result in a teleporter (I have no clue why, I just think it's appropriate, cause a teleporter would be fucking sweet!).
Based on current science, a teleporter is possible but extremely limited (I remember reading they managed to teleport a gas by a whole 3 centimeters). If you allow the scientists behind this research to continue, we might have a fully functional teleporter capable of teleporter people in, let's say 50 years. If you postpone the research for until the economy is fully stable once again, the future of technology seems vague, and a teleporter might first be available after 50 or perhaps even more years from when they get to pick up on their project again.
the worst scenario for preventing science is a dark age of technology where it doesn't moveb forward and is fragile enough it might deteriorate at a rapid speed. Science is what modern society runs on, no matter what people would like to think.
