Nothing to freak out about – we’re just unbelievably small flecks of stardust in a giant, scary universe.
1. Any time you look up at the sky, you are seeing the universe as it was in the past.
If we look at an object 50 million light-years away, we are seeing what the object looked like 50 million years ago because that’s how long it took the light to travel from the object to our eyes.
2. It would take Usain Bolt – running at his highest recorded speed – a little over 262 days to trek the distance of Saturn’s rings.
To put this into perspective, if he ran his top speed around the Earth, it would only take him around 37 days.
