Maggie McKee writes: "New Scientist Space writes:
For the first time, astronomers have found an object on a certain collision course with Earth. Fortunately, it is so small it is not expected to cause any damage, burning up in the atmosphere somewhere above northern Sudan in the wee hours of Tuesday morning. It may, however, produce a brilliant 'shooting star'.
The object is probably about the size of a car and is entering the atmosphere 'sideways' — so it is likely to produce a long trail. It is expected to release about 1 kiloton of energy in the atmosphere — the equivalent of a low-energy nuclear bomb."
"Necessity is the mother of invention" is a silly proverb. "Necessity
is the mother of futile dodges" is much nearer the truth.
