Like I said, the bookshelf. We've found a way to pass ideas in the future -- not yet a way to pass ideas and information into the past.
The assertion in this statement is that there is now - and behind us, somewhere, the past. Time, of course, doesn't function this way - it exists in it's entirety, right now.
Just as those early Indonesian explorers ventured onto uncharted waters, we too can dive into the Undiscovered Country of the future.
The only catch is you can't discover the future with a mind that is fixated on the past.
