How the Universe changed in 2016 (Synopsis) [Starts With A Bang]

“We are not the same persons this year as last; nor are those we love. It is a happy chance if we, changing, continue to love a changed person.” -W. Somerset Maugham

After 13.8 billion years have gone by, you might not think that a year makes much of a difference. A year to the Universe is like 0.2 seconds — the literal blink of an eye — to a human being. Yet even though changes might be gradual, they’re real, and they very much add up over time.

The Earth’s rotation slows, the Moon moves farther away, the Sun heats up, the Big Bang’s leftover glow cools down, stars are born, the galaxies recede and so much more. If we look closely and precisely enough, we can even measure exactly how — and by how much — these changes occur.

Take a fascinating look at how the Universe has changed over the past year, and head into 2017 with a renewed sense of peace!
