cosmology+ elementary particle science:=> offspring :
-insights on creation of spacetime, big bang
-TOE
Change the way science is done:
-Traditionally astronomy: observe, not experiment; tools of physics: accelerators
-Now: cosmological predictions checked, accelerator experiments
Cosmology-true science: ideas not developed, tested in laboratory
-conversely: telescope- test ideas of fundamental physics
-test with enormous energy: only big bang
