How many nanoseconds are in an eon?

Well, an eon is a really, really long time, like the blink of an eye for the universe. And a nanosecond is a tiny, tiny fraction of a second, like a little whisper in the wind. So, there are so many nanoseconds in an eon that it's like trying to count all the happy little trees in a forest - you just have to appreciate the beauty of it all instead.
