Every […] Continue reading

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.

Let’s say the average human has a lifespan of 80 years. To make it a little easier on our calculations, we’ll bump it up to 100 years. Let’s represent that as a dot. The species Homo Sapiens has been around for roughly 200,000 years. If the human lifespan is shown as a single dot, the […] Continue reading
