“It’s hard to build models of inflation that don’t lead to a multiverse. It’s not impossible, so I think there’s still certainly research that needs to be done. But most models of inflation do lead to a multiverse, and evidence for inflation will be pushing us in the direction of taking [it] seriously.” -Alan Guth…

“I know of no other scientist, no other theoretical physicist alive who has a clearer focus on whether our theories and ideas are relevant to the real world. And that’s always what he’s after.” -Neil Turok, on Paul Steinhardt The inflationary Universe is one of the most revolutionary new ways of looking at the cosmos…

“The more clearly we can focus our attention on the wonders and realities of the universe about us, the less taste we shall have for destruction.” -Rachel Carson The idea that the spatial fabric of the Universe itself is expanding, and that’s what’s behind the observed relationship between redshift and distance has long been controversial,…

“Despite its name, the big bang theory is not really a theory of a bang at all. It is really only a theory of the aftermath of a bang.” -Alan Guth Did the Universe begin with the Big Bang? When we discovered the cosmic microwave background, and its properties matched exactly the prediction of the…

“The design of the universe…is very magnificent and shouldn’t be taken for granted.” -Charles W. Misner One of the more puzzling aspects of our Universe is that, no matter which direction we look in, no matter how far away we check, its properties appear to be practically identical. This is surprising, since no signal can…

“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 100 years ago, our conception of the Universe was so small it’s almost laughable. We still were mired…

“In the current cosmological model, only the three lightest elements were created in the first few minutes after the Big Bang; all other elements were produced later in stars.” -Fumagalli, O’Meara and Prochaska, 2011 When it was first conceived, the idea of the Big Bang was spectacular for the fact that it made three incredibly…

“There are two infinities that confuse me: the one in my soul devours me; the one around me will crush me” -Gustave Flaubert Last week, Donald Trump restored the National Space Council, promising to take America and the world to new heights in space. He also made some statements claiming that this is infinity here,…

“By its very nature science knows no boundaries. Walling off any group, for any reason, from full participation damages the entire enterprise of science. We must be scientists without borders.” -Rocky Kolb We normally think of “let there be light” as when the Universe got its start. In a particular sense, this is true, since…

“It is the function of science to discover the existence of a general reign of order in nature and to find the causes governing this order. And this refers in equal measure to the relations of man – social and political – and to the entire universe as a whole.” -Dmitri Mendeleev When the Big…
