Can we cancel light waves?
Answering your questions about life, Earth and the universe
Active noise cancelling headphones work by removing sound waves you don鈥檛 want to hear. Could we do the same for light waves? That鈥檚 this week鈥檚 question, sent to CrowdScience by listener Ahmed in Syria.
It鈥檚 a fascinating idea. Imagine being able to one day walk into a room and turn the sunlight off, rather than turning the artificial light on? Could that ever be possible?
CrowdScience presenter Alex Lathbridge is on a quest to find out if we can cancel light waves and what we might do with that technology if we could.
