"The world you see, nature's greatest and most glorious creation, and the human mind which gazes and wonders at it, and is the most splendid part of it, these are our own everlasting possessions and will remain with us as long as we ourselves remain." -Seneca Asking where in space the Big Bang happened is like asking where the starting point of Earth’s surface is. There’s no one “point” where it began, unless you’re talking about a point in time. The reality is that, as far as space is concerned, the Big Bang occurred everywhere at once, and we have the evidence to prove it. Our view of a small region of the Universe, where each pixel in the image represents a mapped galaxy. On the largest scales, the Universe is the same in all directions and at all measurable location.

If the Big Bang were an explosion, we would discover ourselves in a Universe that had a preferred location with … [Read more...] about Ask Ethan: Where did the Big Bang happen? (Synopsis)
Nanny mcphee and the big bang
“To begin, begin.” -William Wordsworth Is the Big Bang the greatest scientific achievement of the 20th century? I -- along with many others -- would argue that it is. It's something that even young children are curious about! Perhaps it's in our nature to wonder about where we come from? Yet despite the fact that it's been half a century since the Big Bang was validated and its alternatives shown to be wrong, it remains a very difficult concept for most people to understand. More importantly, I have yet to see a good explanation for children, who ought to be learning the scientific story of where we come from as soon as they're old enough to ask. So let's give them one. Have a look at The Big Bang for Children! … [Read more...] about The Big Bang for Children (Synopsis)
"Prediction is very difficult, especially if it's about the future." -Neils Bohr As many of you know, the Big Bang is one of the most powerful scientific theories we have. It's also one of the most unsettling. The idea that our entire Universe -- filled with practically a trillion galaxies -- is only three times as old as our Sun and was once compressed into the size of your thumb is pretty unsettling. As an astute commenter noted earlier this week, I'm asking what persuasive predictions BB has to its credit. Most usually the best I see is new observations favoring one BB variant over another, with some variant or other predicting every possible outcome. I often speak about the cosmic microwave background, nucleosynthesis of the light elements, and the formation of large-scale structure as strong pieces of evidence for the big bang, and this is completely true. Well, there is one last prediction that the Big Bang Theory makes that we have not yet been able to successfully test. Just as … [Read more...] about The Last Great Prediction of the Big Bang!
“These neutrino observations are so exciting and significant that I think we’re about to see the birth of an entirely new branch of astronomy: neutrino astronomy.” -John Bahcall From the Hubble expansion of the Universe to isotropy and homogeneity to the light elements to the leftover radiation glow to the formation of large-scale structure in the Universe, the Big Bang is by far the most successful scientific description of the Universe of all-time.

Hernquist, via http://h-its.org/english/press/pressreleases.php?we_objectID=1080. Even with the add-ons of dark matter, dark energy and inflation, the Big Bang still thrives, accounting for all of those phenomena and leading to observable predictions that have since been verified. But there's one thing it's predicted that we haven't been able to test: a cosmic background of … [Read more...] about Throwback Thursday: The Big Bang’s Last Great Prediction (Synopsis)
