Does having an understanding of Cosmology and the Universe make you fear life and what could happen. Does the scale of it all make you think too much about death and what happens after (non religious) ?
Studying the heavens has brought us great technological achievements. Measuring the angle of sunrays at different locations on Earth revealed to Eratosthenes (~ 240 BC) that the Earth is spherical, which greatly enhanced shipping, once his views caught on, of course.Does having an understanding of Cosmology and the Universe make you fear life and what could happen.

I sometimes wonder about the smaller Asteroids that might slip through the net. They may have a small mass but KE proportional to v^2 packs a lot of energy. Tunguska event being an example. Also if such an event happened over a major city, what else could that trigger i.e. Civil disorder/Nuclear exchange.Observing the cosmos is like coming out of one's cave and seeing creation, and allowing oneself to become a part of it. The good news is that nothing out there is likely going to harm us. Asteroids will now have a hard timing hitting us, if one even gets close enough. No star is close enough to go supnernova and harm us, etc. So jump in, the water's fine!
Yes, but our atmosphere protects us from all but the larger asteroids. The Tunguska object was > 100 meters in size.I sometimes wonder about the smaller Asteroids that might slip through the net.
