Don't keep your physics class in the dark about night—introduce them to the concept with a short animated video! The narrator discusses how the Big Bang set our universe into an ever-expanding motion where the stars we observe now appear as they did millions of years ago. He also explains why we are able to perceive "night" with so many stars in the sky.
