“The oldest and strongest emotion of mankind is fear, and the oldest and strongest kind of fear is fear of the unknown.” -H.P. Lovecraft There’s a unique relationship between everything that exists in the Universe today — the stars and galaxies, the large-scale structure, the leftover glow from the Big Bang, the expansion rate, etc.…

“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…

“We’ve known for a long time that the universe is expanding. But about 15 years ago, my colleagues and I discovered that it is expanding faster and faster. That is, the universe is accelerating, and that was not expected, but it is now attributed to this mysterious stuff called dark energy which seems to make…

“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.

“Nobody grows old merely by living a number of years. We grow old by deserting our ideals.
