- 虚数時間。なんという発想。Stephen Hawking 語録（その４）。
imaginary time is a difficult concept to grasp, and it is probably the one that has caused the greatest problems for readers of my book. i have also been criticized fiercely by philosophers for using imaginary time. how can imaginary time have anything to do with the real universe? i think these philosophers have not learned the lessons of history. i was once considered obvious that the earth was flat and the sun went around the earth, yet since the time of copernicus and galileo, we have had to adjust to the idea that the earth is round and that it goes around the sun. similarly, it was long obvious that time went at the same rate for every observer but since einstein, we have had to accept that time goes at different rates for different observers. it also seemed obvious that the universe had a unique history, yet since the discovery of quantum mechanics, we have had to consider the universe as having every possible history. i want to suggest that the idea of imaginary time is something that we will also have to come to accept. it is an intellectual leap of the same order as believing that the world is round. i think that imaginary time will come to seem as natural as a round earth does now. there are not many flat earthers left in the educated world.

hughes mentions metal deterioration,
but it sounds like he’s not really deterioration mentally,
his brain is aging not actually deteriorating, which would be a disease.
