HOLY FUCKING SHIT IT'S REMINGTON!!!!

HOW'S IT GOING DUDE?

Not bad. I'm being all adult and working and stuff.

Also annoying about BTTF: If I travel through a wormhole connecting the same point in space at two different time coordinates, wouldn't I just pop out into the blackness of interstellar space, since Earth is not actually at the same coordinates now that it was in 1985?

Saying "the same point in space, but a different point in time" isn't really meaningful without specifying a frame of reference. The wormhole would connect one point in space-time to another point in space-time; spending on the reference frame and coordinate system, those two points could be observed to be at the same location or even at the same time.  If you define your space coordinate system to something like latitude and longitude so that it the same coordinates in it map to the same spot on the surface of the earth regardless of what day of the year it is, then it's perfectly reasonable to "go to the same place, only in 1985" and show up in atmo like you'd expect. Mind you, that's not an inertial reference frame, so either conservation of momentum gets borked or you get smeared across the landscape.

Im still going to go with a trip forward or backward thirty years is the equivalent of a one way trip to the scattered disk.
