No, it’s not a book or magazine or pamphlet. It is a single quote from the Astronomer Royal of the United Kingdom, Sir Martin Rees.
It goes like this…….
“There’s an unthinking tendency to think that we, humans, in our present state, will be around to witness the death of our Sun, and the vaporization of all life on Earth. But, due to evolution, any humans alive in 6 billion years time will be as different from us as we are from bacteria”!
The most arresting thing I’ve ever read.
