This is one for all those pedantics who point out the mistakes in songs. Simon Singh got Katie Melua to re-record Nine Million Bicycles due to its scientific errors. The problematic verse in the original version of Nine Million Bicycles is:
We are 12 billion light years from the edge/That’s a guess/No one can ever say it’s true/But I know that I will always be with you.
The new, more scientifically accurate verse by Simon Singh, recorded here goes:
We are 13.7 billion light years from the edge of the observable universe/That’s a good estimate with well-defined error bars/Scientists say it’s true, but acknowledge that it may be refined/And with the available information, I predict that I will always be with you.
