What would you like to know about your Universe — The third online poll
This poll is now closed. The most popular question was: "What are dark energy and dark matter?" We will publish the answer in an article and podcast on Plus shortly. Thank you for taking part!
This is our third online poll in our series to celebrate the International Year of Astronomy 2009. Choose your favourite question from the list on the right, and we'll put the one that proves most popular to world-leading astronomers and cosmologists, including Astronomer Royal Martin Rees and author and cosmologist John D. Barrow. The poll will remain open for a month and the answer will be published in a Plus article and podcast soon after. If your most burning question is not on this list, then leave a comment on this blog and we'll endeavour to include it in a future poll — there will be four more polls dotted throughout the year.
The most popular questions in polls far were was What happened before the Big Bang? and Are the constants of nature really constant?. Read the answers by clicking on the links, and discuss them on our blog.

Dark matter is possibly "easy" to determine: neutrinos have mass. That simple (but hugely ignored) fact could provide both sufficient mass and energy to explain the otherwise unobserved masses and energies that puzzle us.
But how Gravity works - well, that's something I would really like to know.
