The 4 Percent Universe: Dark Matter, Dark Energy, and the Race to Discover the Rest of Reality
“Fascinating . . . essentially the most vital tales within the background of science.”— Washington Post
In fresh years, a handful of scientists has been racing to give an explanation for a hectic element of our universe: simply four percentage of it involves the problem that makes up you, me, and each big name and planet. the remaining is totally unknown.
Richard Panek tells the dramatic tale of the way scientists reached this cosmos-shattering end. In brilliant aspect, he narrates the hunt to discover the “dark” subject and a fair more odd substance referred to as darkish power that make up ninety six percentage of the universe. this can be probably the best secret in all of technology, and fixing it is going to convey repute, investment, and positively a Nobel Prize. in keeping with 1000's of interviews and in-depth, on-site reporting, the e-book bargains an intimate portrait of the sour rivalries and fruitful collaborations, the eureka moments and blind alleys, that experience redefined technology and reinvented the universe.
“A full of life new account of twentieth-century (plus a bit twenty-first-century) cosmology . . . The e-book is as a lot approximately how the technological know-how obtained performed as in regards to the technology itself.”—Salon

Pioneer 10, scientists not less than knew the signal's frequency; they knew the place to show to at the radio dial. Karl van Bibber did not have that luxurious. yet he did have a bonus over different dark-matter hunters: He'd understand his prey if he observed it. How do you notice whatever that's darkish, if through "dark" you suggest, as astronomers starting within the Nineteen Seventies and Eighties did, "impossible to see"? How do you do anything that's, through your individual definition, very unlikely to do? you do not. You reconsider the query. For.
