“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 [the idea of a]…

“Were the succession of stars endless, then the background of the sky would present us a uniform luminosity, like that displayed by the Galaxy-since there could be absolutely no point, in all that background, at which would not exist a star.” -Edgar Allan Poe The master of the macabre, little known to most, was actually…

“Revolutions are something you see only in retrospect.” –Alan Greenspan If there’s one thing you can be certain of when it comes to the fundamental, scientific truths of our Universe, it’s this: someday, in the not too distant future, those truths will be superseded by more fundamental ones. And even those, quite likely, won’t be…

“For my part I know nothing with any certainty, but the sight of the stars makes me dream.” –Vincent Van Gogh When we look out into the Universe, farther back to greater distances, we’re also looking back in time, farther and farther into the past. If we could look back far enough, close enough to…

“Scientific ideas should be simple, explanatory, predictive. The inflationary multiverse as currently understood appears to have none of those properties.” –Paul Steinhardt, 2014 Cosmic inflation is alternately talked about by serious scientists as either the definitive beginning to our Universe, the thing that happened before and set up the Big Bang with absolute certainty, or…

“Nothing is lost… Everything is transformed.” –Michael Ende If you take all the kinetic motion out of a system, and have all the particles that make it up perfectly at rest, somehow even overcoming intrinsic quantum effects, you’d reach absolute zero, the theoretically lowest temperature of all. But what about the other direction? Is there a…

“We are told to let our light shine, and if it does, we won’t need to tell anybody it does. Lighthouses don’t fire cannons to call attention to their shining- they just shine.” –Dwight L. Moody When it comes to the farthest thing we can see in the Universe, that’s the Cosmic Microwave Background, or the…

“Those who know that the consensus of many centuries has sanctioned the conception that the earth remains at rest in the middle of the heavens as its center, would, I reflected, regard it as an insane pronouncement if I made the opposite assertion that the earth moves.” –Nicolaus Copernicus There are certain words that simply…

“Silently, one by one, in the infinite meadows of heaven, Blossomed the lovely stars, the forget-me-nots of the angels.” –Longfellow The cosmic microwave background is a thing of beauty, as not only does its uniform, cold temperature reveal a hot, dense past that began with the hot Big Bang, but its fluctuations reveal a pattern…

“Light thinks it travels faster than anything but it is wrong. No matter how fast light travels, it finds the darkness has always got there first, and is waiting for it.” –Terry Pratchett If you want, you can imagine back in the Universe to a time before it looked anything like ours did. Before there…
