Lawrence M. Krauss

American theoretical physicist, cosmologist and author who is director of the Origins Project at Arizona State University. He has written a number of science books for the layman, including Fear of Physics and Quantum Man: Richard Feynman's Life in Science.


Science Quotes by Lawrence M. Krauss (8 quotes)

If the universe is measurably curved today, cosmologists must accept the miraculous fact that this is so for the first time in the 1010-year history of the universe; if it had been measurably non-flat at much earlier times, it would be much more obviously curved today than it is. This line of reasoning suggests that the observable universe is essentially exactly flat: that it contains precisely the critical density of mass.
— Lawrence M. Krauss
(1986). As quoted in Isaac Asimov's Book of Science and Nature Quotations.

Of the 10,000 or so meteorites that have been collected and analyzed, eight are particularly unusual. They are so unusual, in fact, that since 1979 some investigators have thought they might have originated not in asteroids, as most meteorites did, but on the surface of Mars.
— Lawrence M. Krauss
In Scientific American, (Dec 1986), 255, 80.

One of the most poetic facts I know about the universe is that essentially every atom in your body was once inside a star that exploded. Moreover, the atoms in your left hand probably came from a different star than did those in your right. We are all, literally, star children, and our bodies made of stardust.
— Lawrence M. Krauss

Science has taught us to think the unthinkable. Because when nature is the guide—rather than a priori prejudices, hopes, fears or desires—we are forced out of our comfort zone. One by one, pillars of classical logic have fallen by the wayside as science progressed in the 20th century, from Einstein's realization that measurements of space and time were not absolute but observer-dependent, to quantum mechanics, which not only put fundamental limits on what we can empirically know but also demonstrated that elementary particles and the atoms they form are doing a million seemingly impossible things at once.
— Lawrence M. Krauss

The illusion of purpose and design is perhaps the most pervasive illusion about nature that science has to confront on a daily basis. Everywhere we look, it appears that the world was designed so that we could flourish.

There is already overwhelming evidence that the visible matter within galaxies may account for less than 10 percent of the galaxies’ actual mass: the rest, not yet directly detectable by observers on the earth, is probably distributed within and around each galaxy.
— Lawrence M. Krauss
(1986). As quoted in Isaac Asimov's Book of Science and Nature Quotations.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
