Whats to stop me from burning the Certificate. Magic? Not getting to the past will work but that isn't compatible with an assumption of a time machine.
There seems to be difficulty here for some of POINT OF VIEW. The whole idea of time travel REQUIRES a muliverse of branching time.
You decide some certificate must be burned.
You happen to have a Handy Dandy Acme Time Machine.
You go go back in the past.
You burn the certificate.
You go forward
You see a world in which the certificate burned. IT IS NOT THE WORLD YOU STARTED IN. You most likely weren't even born in the BRANCHED world.
The world you came from STILL EXISTS. Its just on a different track. You didn't change a thing in the world you came from. You created a whole new branch of time.
Where once there was one branch now there are two. Two of many.
