Mas a parte das bicicletas está certa!

We are twelve 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.

On September 30, 2005, an article appeared in The Guardian newspaper in which physicist Simon Singh criticised the song's lyrics. Singh interpreted the first lyric as a statement that the observable universe was twelve billion years old, which he said was incorrect; according to "the very latest data", the universe was actually 13.7 billion years old. He added, "the next line in the song is unforgivable. To say that the age of the universe is "a guess" is an insult to a century of astronomical progress. The age of the universe is not just "a guess", but rather it is a carefully measured number that is now known to a high degree of accuracy". He wrote replacement lyrics which he believed would, if used, remedy his concerns:

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.
