Like no other science, astrophysics cross-pollinate s the expertise of chemists, biologists, geologists and physicists, all to discover the past, present, and future of the cosmos-and our humble place within it.

If God to you is where science has yet to tread, then God is an ever-receding pocket.

Space in general gave us GPS - that's not specifically NASA, but it's investments in space.

When your reasons for believing something are justified ad hoc, you are left susceptible to further discoveries undermining the rationale for that belief.

Note, however, that you cannot simply add temperatures the way you can add volumes or weights. Two people in bed, each with body temperatures of 98.6 degrees Fahrenheit, do not normally create a 197.2 degree under-the-cover oven.

If humans one day become extinct from a catastrophic collision, there would be no greater tragedy in the history of life in the universe. Not because we lacked the brain power to protect ourselves but because we lacked the foresight. The dominant species that replaces us in post-apocalyptic Earth just might wonder, as they gaze upon our mounted skeletons in their natural history museums, why large headed Homo sapiens fared no better than the proverbially peabrained dinosaurs.

We already know the limits of Einstein's theories. From the centers of black holes at the very beginning of the universe - we call these singularities - Einstein's equations fail. In fact, people have joked that's where God is dividing by zero.
