The universe is ancient. It has existed for millions and millions of years. We have only been here for a fraction of the time. Kurtis Baute explains the history of the universe in a video of falling dominoes. It took him 4 days to set up the dominoes in a warehouse. Each domino represents one million years and as the dominoes fall, he jogs around them and keeps on explaining what is happening in the history of the universe at this time.
It begins with the big bang and out of the 13,799 dominoes, humans only exist in the last three. This shows how little time we have spent here when we look at the grand scale of things. You can watch the video here:
