  • News from the world of maths: Plus podcast: Are the constants of nature really constant?

    23 July, 2009
    Thursday, July 23, 2009

    As part of our celebration of the International Year of Astronomy 2009 we brought you the article Are the constants of nature really constant?, in which John D. Barrow tells us how it all depends on which constants you choose. In the podcast of this interview you can hear how changes in the constants that define our Universe might have implications for extra dimensions, gravity, and climbing flies...

    Listen to the podcast.

    If this has whetted your appetite for astronomy, then why not take part in our online poll to nominate the next question we'll put to the experts.
