There is a very small chance that the message on the usa dollar bills is
proof of time travel of some sort.

However this idea is so ridicilous that even I don't really want to go into
that one.

But I am going to write it down anyway.

It's hard to imagine that it's actually time travel, perhaps via quantum
entanglement lol.

I think a conspiracy is more likely.

However time travel cannot be completely ruled out.

It could be an attempt from the future to warn us that we are all in danger
and about to do something very bad.

Problem for the future is that much information was lost by the time they
created time travel.

Only vague references/dates and the numbers 9/11 and such remained in memory
of people or so...

Could have taken them thousands of years maybe even more to re-build society
after some terrible destruction/event.

The time travel would have to be gone back to the 1900's or so... perhaps
even in world war 1

It must have been before the dollar bills were designed.

Or alternatively small modifications made...

There is something strange with these dollar bills though... I know that
much... it's too strange to ignore !
