:50:01
The lab is an awful, awful mess.
:50:06
Attaboy.
:50:08
Obviously,
the time continuum has been disrupted...
:50:11
...creating this new
temporal event sequence...
:50:13
...resulting in this alternate reality.
- English, Doc.
:50:16
Here, here, here. Let me illustrate.
:50:23
Imagine that this line represents time.
:50:27
Here's the present, 1985,
the future, and the past.
:50:33
Prior to this point in time,
somewhere in the past...
:50:36
...the time line skewed into this tangent...
:50:39
...creating an alternate 1985.
:50:42
Alternate to you, me, and Einstein...
:50:46
...but reality for everyone else.
:50:53
Recognize this?
:50:55
It's the bag the sports book came in.
:50:57
I know, because the receipt
was still inside.
:51:00
I found them in the time machine,
along with this.
:51:09
It's the top of Biff's cane.
I mean old Biff, from the future.
:51:12
Correct. It was in the time machine
because Biff was in the time machine...
:51:17
...with the Sports Almanac.
:51:19
Holy shit.
:51:20
You see, while we were in the future...
:51:23
...Biff got the sports book, stole
the time machine, went back in time...
:51:27
...and gave the book to himself
at some point in the past.
:51:30
Look. It says right here...
:51:34
...that Biff made his first $1,000,000
betting on a horserace in 1958.
:51:40
He wasn't just lucky.
:51:42
He knew, because he had
the race results in the Sports Almanac.
:51:45
That's how he made his entire fortune.
:51:48
Look at his pocket with a magnifying glass.
:51:53
The Almanac.
