His publications included The Large Scale Structure of Space-Time (1973; coauthored with G.F.R. Ellis), Superspace and Supergravity (1981), The Very Early Universe (1983), and the best sellers A Brief History of Time: From the Big Bang to Black Holes (1988), The Universe in a Nutshell (2001), A Briefer History of Time (2005), and The Grand Design (2010; coauthored with Leonard Mlodinow).
All About Earth. Since we live here, you might think we know all there is to know about Earth. Not at all, actually! We have a lot we can learn about our home planet. Learn more about Earth and all the planets in our solar system. Play. Go With the Flow!
10 Things. Our solar system is made up of a star, eight planets, and countless smaller bodies such as dwarf planets, asteroids, and comets. Our solar system orbits the center of the Milky Way galaxy at about 515,000 mph (828,000 kph). We're in one of the galaxy's four spiral arms.

That moment was the Big Bang. We can even work out when it happened from the speed of the galaxies: about 14 billion years ago. We can't actually see the galaxies moving, but the clue is in the
Multiverse theory assumes that our universe is only a small member of an enormous multitude of universes. The idea of the multiverse arose from a now widely popular theory—the inflation theory. It was developed in 1980 and filled in some information gaps where the Big Bang theory was lacking. Although the Big Bang theory offers a valid
The new theory suggests that there was a third dark-energy episode not long after the big bang, which expanded the universe faster than astronomers had predicted. The existence of this "early dark energy" could account for the tension between the two Hubble constant values, Riess said.
The WMAP satellite measures the basic parameters of the Big Bang theory including the fate of the universe. The results suggest the geometry of the universe is flat and will expand forever. Further study of the dark energy with future experiments and space missions is needed to understand its nature and effect on the rate of future expanison.

For a few physicists, the Big Bang wasn't the beginning of the universe. Rather, they say, the universe existed before that point, stretching forever into the past as well as the future. While
