Is it physically possible for you to get back to THIS time line once you leave?

If all 7 Billion of us here each had our own time machine do you think that would we would end up trashing the rest of the local worldlines?

Recomended movies:
Arthur C. Clarks’ 2001
WaterWorld (Kevin Kosner)
Dances With Wolves
Chrimson Tide
Forest Gump
Little Big Man

There are a lot of good movies of substance. Good movies like good books are more than a mere passtime. I’ve got one heck of a book collection that I probably won’t need come 2036. Any suggestions on where to drop it off? (It weighs about 3000 pounds.)

Watch out for the time cops on your way out.
