Letter: Letters : . . .

From Stephen Coast (age 15)

I think Phil Bagnall missed a key point. If a person had built a time machine
and set it to go one day forward, he would expect to arrive at his position 24
hours later.

The problem is that while our brave inventor travelled through time, the
Earth has also spun above its axis, moved several million kilometres around the
Sun, and the whole Solar System has also moved in space. So when he popped into
existence a day later, he would find himself in the murky void looking at a
rapidly departing Earth.
