Frightening Quote by Leonard Susskind
““The frightening thing—frightening, I don’t know if it’s frightening—frustrating, frightening, fascinating thing is we know with virtual certainty that the universe is at least a thousand times bigger in volume than the horizon, than we can ever, ever, ever in principal ever see. So we know there’s stuff out there that we will never be able to detect. And we can’t tell what it is. We can’t tell if it’s similar to us.””
