The Last 2 Minutes of History

Down on Earth, it’s easy to think the passage of 100 years is a long time. After all, it’s certainly longer than a human’s life expectancy.

It shrinks the entire 13.8 billion years that the universe has been around into one calendar year where each second equates to a few hundred years.
