What is coming to Earth tomorrow?
“Old seconds. A whole swarm of them.”
What is an old second?
“It’s a time period of about a second’s duration from long way in the past, so we can actually say it’s an old second.”
Is it a small fraction of history?
“Yes, you can say that.”
What do you do if you see an old second and instantly get hit by it?
“Yet, no human being has been mutilated by an old second. It is a very small risk we are talking about. Not much bigger than a hazelnut or a goldcrest. But the risk is there. It would be stupid to deny. If it is as big as a goldcrest, the risk will fly away. If it is the size of a hazelnut, it may be eaten.”
