Today's BBC website carries the news that scientists have discovered that the original kilogram, the standard by which all weight is measured, has become slightly heavier since it was cast from platinum-iridium in France 137 years ago. This is apparently due to small amounts of pollution collecting on its surface, and as a result, everything else has become lighter, including us.
As Peter Cumpson, professor of MicroElectroMechanical systems at Newcastle University, puts it "It is a really tiny effect, but strictly speaking we are all slightly lighter than we were in the late 1800s."
This means that I'm now sat in a Belfast hotel room weighing less than I thought I did when I left home, even though my weight has stayed exactly the same.
Not only that, but as the distance in kilometres between here and home is based on the speed of light, which is derived from how fast light might travel between two fixed points even though Albert Einstein declared that there were no fixed points, I'm now convincing myself that post-Christmas gym exertions aren't worth the effort. After all, if each walk down the drive is actually a slightly further distance travelled, but in the same amount of time as before, surely I must have got faster as well as lighter?
Just need someone to sort Time out and I can convince myself that I'm getting younger as well...
