Showing results for "paradox" in Cosmology

Given the fact that there are perhaps 400 billion stars in our galaxy alone and perhaps 400 billion galaxies in the universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials?

This is an indispensable guide to physics that offers readers an overview of the most popular physics topics written in an accessible, irreverent, and engaging manner while still maintaining a tone of wry skepticism. Even the novice will be able to follow along, as the topics are addressed using plain English and (almost) no equations. Veterans of popular physics will also find their nagging questions addressed, like whether the universe can expand faster than light.

Were ancient Greek philosophers right about reality being only an illusion? What was really the biggest blunder of Einstein's life? Is everything we've been taught about the universe incorrect? In The Unobservable Universe, visionary scientist and engineer Scott M. Tyson successfully unravels cosmology from the level of rocket science and brings it down to Earth, demystifying the universe in terms that laymen can comprehend and enjoy, splitting atoms but not hairs on this magical mystery tour of the outback of time and space.
