So give me a second…

- One thousand seconds is equal to just under 17 minutes.
- One
*million* seconds is 11 and a half days.
- One
*billion* seconds is 32 years.
- One
*trillion* seconds is 32,000 years.
- One
*quadrillion* seconds is 32,000,000 years.
- One
*quintillion* seconds is… simply, longer than the universe has existed

So seconds add up, but the above also gives context to some otherwise usually intangible, big numbers. A week is 604,800 seconds. A 30-day month is 2,592,000 seconds. The average human lifespan takes place over a span of two-and-a-half billion seconds.

A second seems to us a very small measurement of time in our everyday life, but in reality, a second is an *entire universe*. Are you ready to get REALLY REALLY small? Consider Planck Time, which is the smallest possible division of time. If you think a second is tiny, here’s the mind-boggling thing: *There are more units of Planck Time in a single second than there have been all the seconds since the Big Bang.*
