:04:01
Here, here, here. Let me illustrate.
:04:07
Imagine that this line represents time.
:04:12
Here's the present, 1985,
the future, and the past.
:04:18
Prior to this point in time,
somewhere in the past...
:04:21
...the time line skewed into this tangent...
:04:23
...creating an alternate 1985.
:04:26
Alternate to you, me, and Einstein...
:04:30
...but reality for everyone else.
:04:37
Recognize this?
:04:39
- It's the bag the sports book came in.
:04:41
I know, because the receipt
was still inside.
:04:44
I found them in the time machine,
along with this.
:04:53
It's the top of Biff's cane.
I mean old Biff, from the future.
:04:57
Correct. It was in the time machine
because Biff was in the time machine...
:05:01
...with the Sports Almanac.
:05:04
Holy shit.
:05:05
You see, while we were in the future...
:05:07
...Biff got the sports book, stole
the time machine, went back in time...
:05:11
...and gave the book to himself
at some point in the past.
:05:15
Look. It says right here...
:05:19
...that Biff made his first $1,000,000
betting on a horserace in 1958.
:05:25
He wasn't just lucky.
:05:26
He knew, because he had
the race results in the Sports Almanac.
:05:29
That's how he made his entire fortune.
:05:33
Look at his pocket with a magnifying glass.
:05:37
The Almanac.
:05:40
Son of a bitch stole my idea.
:05:43
- He must have been listening when I....
:05:47
It's my fault.
:05:49
The whole thing is my fault.
If I hadn't bought that damn book...
:05:52
...none of this would have happened.
:05:54
-It's all in the past.
-The future.
:05:56
Whatever. It demonstrates precisely
how time travel can be misused...
