What would you like to know about your Universe — The second poll

This poll is now closed. The most popular question was: "Are the constants of nature really constant?" We will publish the answer in an article and podcast on Plus shortly. Thank you for taking part!

This is our second 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 five more polls dotted throughout the year.

The most popular question in our first poll was "What happened before the Big Bang?". You can now read the mind-boggling answer here on Plus, and discuss it on our blog.

I would be interested to know about the rings of Saturn. Particular points might be:
- Why is Saturn the only planet in the solar system with rings (or is it?)?
- How dense are the rings - would it be possible for a space vehicle to go through them or would it be destroyed in the attempt?
- How quickly are the rings orbiting the planet or are they in stationary orbit?
- What are the rings comprised of - dust, larger particles?

I would be interested to know if you could explain how gravity actually works: what is it about bodies with mass that attracts?

I'd love John to explain what a "Boltzmann Brain" is - that was one of the freakiest things I heard at the very Early Universe conference in 2007 - a very odd merger of Physics, astronomy and philosophy!

Saturn is not the only planet with rings. All the gas giants have them.
- The rings are mostly dust,ice, and cosmic debris so any attempt to go through them would possibly destroy any ship that goes through it.

In the last ever paragraph of 'A brief History of Time' Stephen Hawking predicts the unified theory, which can empower scientists, philosophers and public to know the nature of God. I would like to know the efforts in this direction, how do we get there and what are the immediate obstacles before us.

Also nice would be a discussion whether free will exists and whether the universe is deterministic; and are both concepts equivalent?

On matters closer to Earth, I wonder how the LHC finds answers within the terabytes streaming from its detecctors.

We would like to apologise to everyone who, due to a technical glitch on Plus, haven't been able to register their vote on this second poll. We're very pleased to announce the problem is now resolved, and you can once again tell us what you would like to know about your Universe!

Resuming normal transmission....

What is the universe made of... quite a broad question. I was torn between this question, and the shape of the universe question. I eventually chose shape as my curiosity. I don't think "Why are planets round" warranted the opportunity to be on such a pole... it's clearly because gravity is a central force, so stuff settles that way. To the person who is curious how gravity works, read a bit about general relativity, Einstein answered that question with some math he borrowed from brilliant men. And Jesvin, as far as Stephen Hawking and his discussion of guts goes, there hasn't been much progress. Firstly, I hope it's understood that Hawking uses the word god as a metaphor, not unlike Einstien did. Secondly, look for a blog by Peter Woit of Columbia University called "Not Even Wrong." We, as physicists an mathematicians, are far from a unified theory of everything. In fact, it might not even be possible to come up with one.

Maths phobe goes forth to multiply

A date for your TV diary: next Tuesday, the 31st of March 2009, at 9pm, BBC2 will screen the Horizon programme Alan and Marcus go forth and multiply, in which actor and comedian Alan Davies explores his fear of maths with mathematician and author Marcus du Sautoy. Together they will visit the fourth dimension, cross the universe and explore infinity, and along the way Alan does battle with some of the toughest maths questions of our age. Let's hope he's done some swotting with Plus first!

Travels in a mathematical world

If you enjoy the Plus podcasts, then you might also like a maths podcast published by Peter Rowlett, the University Liaison Officer of the Institute of Mathematics and its Applications. On his travels he records short interviews with interesting mathematicians talking about their career and work. There are also episodes on the history of mathematics and on mathematical news, and the webpage also contains a blog.

Are entries with two authors eligible for the contest?

Yes, though if you win, you'll have to share the prize...

Do pictures count....I mean, if they count on them? I've got a really neat picture file that's worth, probably, a trillion mathematicos.

May I send two entries?

The answer to the previous two questions is: yes, you can send two entries, and pictures are very welcome as part of articles, or with a good explanatory article, but not on their own unfortunately.

We're looking forward to your entries!
