Takeaways:

• Space is a property of our universe that gives us a sense of the size of an object and the distance between two objects.
• "meter" is the standard unit to measure distances in space.
• Today, "meter" is officially defined as "the length of the path travelled by light in vacuum during a time interval of 1/299,792,458 of a second".
• Roughly, a "meter" is the length of a pendulum the length of a pendulum with a half-period of one second.
