“Gamow was fantastic in his ideas. He was right, he was wrong. More often wrong than right. Always interesting; … and when his idea was not wrong it was not only right, it was new.” -Edward Teller There are few scientific idea more revered or more important than the Big Bang. For the vast majority…

“Nobody grows old merely by living a number of years. We grow old by deserting our ideals. Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul.” -Samuel Ullman When it comes to the Universe, there are some dead giveaways as to what its age is. Its elemental composition changes, the types…

“Space is certainly something more complicated than the average person would probably realize. Space is not just an empty background in which things happen.” -Alan Guth If you go back in time, earlier and earlier, things get hotter, denser and more energetic. But there’s a limit to how far back you can go, and that…

“That’s all regular matter, just five percent. A quarter is “dark matter,” which is invisible and detectable only by gravitational pull, and a whopping 70 percent of the universe is made up of “dark energy,” described as a cosmic antigravity, as yet totally unknowable. It’s basically all mystery out there – all of it, with…

“Mathematicians deal with possible worlds, with an infinite number of logically consistent systems. Observers explore the one particular world we inhabit. Between the two stands the theorist. He studies possible worlds but only those which are compatible with the information furnished by observers. In other words, theory attempts to segregate the minimum number of possible…

The Two Big Bangs (Synopsis)

“These theories were based on the hypothesis that all the matter in the universe was created in one big bang at a particular time in the remote past.” -Fred Hoyle It’s making headlines every time someone brings it up: a quantum calculation, a new theory or some mathematical evidence proves it once and for all: there…

“Our knowledge of physics only takes us back so far. Before this instant of cosmic time, all the laws of physics or chemistry are as evanescent as rings of smoke.” -Joe Silk When people use the word theory colloquially, they use it to mean an “idea” or a “possibility” that could conceivably be at play.…

“Any fool can criticize, condemn and complain – and most fools do.” -Benjamin Franklin The history of science is rife with stories of cases where a person or team, usually with a lot of clout, reached a conclusion that seemed incontrovertible. When that occurs, we often find that subsequent measurements agree with that conclusion, even if that…

“To know that we know what we know, and to know that we do not know what we do not know, that is true knowledge.” –Nicolaus Copernicus As we peel back the layers of information deeper and deeper into the Universe’s history, we uncover progressively more knowledge about how everything we know today came to…

“The paradigm of physics — with its interplay of data, theory and prediction — is the most powerful in science.” –Geoffrey West Cosmic inflation, our earliest theory of the Universe and the phenomenon that sets up the Big Bang, didn’t just explain a number of puzzles, but made a slew of new predictions for the Universe. In the subsequent…
