"Welcome to the Universe is a personal guided tour of the cosmos by three of today's leading astrophysicists. Inspired by the enormously popular introductory astronomy course that Neil deGrasse Tyson, Michael A. Strauss, and J. Richard Gott taught together at Princeton, this book covers it all--from planets, stars, and galaxies to black holes, wormholes, and time travel. Describing the latest discoveries in astrophysics, the informative and entertaining...

Draws from various sources to relate Albert Einstein's ethical and philosophical views on the cosmos, touching on such topics as God, prayer, wealth, peace, creativity, nature, imagination, and curiosity.

"From the world-renowned physicist, co-founder of the World Science Festival, and best-selling author of The Elegant Universe comes this utterly captivating exploration of deep time and humanity's search for purpose. Brian Greene takes readers on a breathtaking journey from the big bang to the end of time and invites us to ponder meaning in the face of this unimaginable expanse. He shows us how, from its original orderly state the universe has been...

"Cosmology is in crisis. The more we discover, the more puzzling the universe appears to be. How and why are the laws of nature what they are? A philosopher and a physicist, world-renowned for their radical ideas in their fields, argue for a revolution. To keep cosmology scientific, we must replace the old view in which the universe is governed by immutable laws by a new one in which laws evolve. Then we can hope to explain them. The revolution that...

"In We Have No Idea, they explore the biggest unknowns in the universe, why these things are still mysteries, and what a lot of smart people are doing to figure out the answers (or at least ask the right questions). While they're at it, they helpfully demystify many complicated things we do know about, from quarks and neutrinos to gravitational waves and exploding black holes. With equal doses of humor and delight, they invite us to see the universe...

"As a physicist, Alan Lightman has always held a scientific view of the world. As a teenager experimenting in his own laboratory, he was impressed by the logic and materiality of a universe governed by a small number of disembodied forces and laws that decree all things in the world are material and impermanent. But one summer evening, while looking at the stars from a small boat at sea, Lightman was overcome by the overwhelming sensation that he...

Perhaps the biggest question Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. Pondering this mystery led Hawking to study the big bang origin of the universe, but his early work ran into a crisis when the math predicted many big bangs producing a multiverse-countless different universes, most far too bizarre to harbor life. Holed up in the theoretical physics...

A tour of outer space explores the solar system as well as stars, galaxies, and the birth of planets, and speculates on whether other intelligent beings exist in the universe.

"This book provides a tour of the “greatest hits” of cosmological discoveries?the ideas that reshaped our universe over the past century. The cosmos, once understood as a stagnant place, filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is someone at the forefront of the research?an astrophysicist who literally...
