One of the most revolutionary concepts that we learned in the 20th century is that time is not a universal measurement. The rate at which it passes depends entirely on your speed and acceleration at any given moment. As the latest episode of MinutePhysics explains, the rate at which time passes actually slows down the more you're moving. And I'm not talking about your perception of time, which recent research suggests is actually speeding up, thanks to the over-abundance of technology in our lives. I'm talking about the rate of actual time, shown in numerous experiments to slow down when particles such as muons and photons speed up. In Einstein's theory of relativity, time dilation describes a difference of elapsed time between two events, as measured by observers that are either moving relative to each other, or differently, depending on their proximity to a gravitational mass.

And why are there so many terms to choose from? I usually end up saying I'm "seeing" someone, even if it's been six months and we go on extremely romantic dates — I'm just being sad girl about asking them to make it exclusive or leave me alone forever. Nobody wants it. Dating can mean anything from being in a committed, serious relationship to simply going on a handful of dates for a certain period of time.

Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order.
