The #BigQuestions

To mark the launch of Mosaic we’re on a quest to identify the most important question science has yet to answer about life.

We’ve been asking leading figures from around the world to participate by sending in their questions. We received more than 75 questions (check them all out below) relating to everything from aliens to the brain, intelligence and consciousness to ageing and curing disease to sustainability and climate change.

All these questions have been themed together to form a definitive top 25 #BigQuestions on our Facebook page that we hope will spark a national conversation to determine THE one everyone believes most needs solving. We want to get as many people as possible voting through likes, comments and shares and the top question will become the theme for a live discussion, broadcast on our Youtube and Google+ pages in early April.

Help us start the conversation by following the link where you can vote for as many of the questions as you’d like: http://on.fb.me/1hXvjTC. If you’d like to spread the word, please share the Facebook album once you’ve voted or Tweet about it by using the text below:
