"Does photosynthesis occur in moonlight?" and "What’s the best way to treat insomnia?" BBC Click Radio presenter Gareth Mitchell answers life's big questions
Everyone at Focus towers was excited to see Brian Cox's new series Wonders of the Universe on Sunday.
Don't worry if you missed it, you can catch the show on iPlayer and the next three episodes on Sunday nights at 9pm on BBC 2.
You can also go behind the scenes with Brian and get the answers to the 50 biggest questions about the Universe from astronomy guru Dr Stuart Clark in the new issue of Focus magazine, on sale and on the iPad now.
What are we made of? Where did we come from? Brian answers these fundamental questions by telling the story of the Universe, which is also the story of humanity. After all, we're made of the same 92 elements as everything else in the Universe.
In this special film made to accompany the book of the series, Brian explains how it all started - how the 'ingredients' in the Big Bang were transformed to form everything around us.
