Light is just one of those things we take for granted. It's there (eventually) when we wake up in the morning. It's around all day, until eventually it dissipates so we all go indoors and... turn on the lights.

And while scientists have studied light for centuries, there's still more to learn. And each breakthrough leads the next, resulting in some fascinating new possibilities that were only considered possible in science-fiction stories. Here are a few that teams are working on today: 

1. Bending light for invisibility
2. Light pushes and pulls things
3. Ghost imaging: Pictures in the dark
4. Quantum slits in time
5. Overtaking light on a bicycle

You might say these amazing discoveries about light keep coming in waves. 

Thank you, thank you, I'll let myself out.
