Nikkalmati:
Query: What other methods could DD use to know the past? Even if we
> could go back, could we ever go forward? After all, there is no
there there, right? What is so terrible about meeting yourself in
> the past? What was it Hermione had been warned about?


June:
Nikkalmati, I liked what you had to say, it really got me thinking.
There are a few answers to why you should not meet yourself in the
past or the future. In Back to the Future 2 Doc Brown tells Marty "I
foresee two possibilities. One, coming face to face with herself 30
years older would put her into shock and she'd simply pass out. Or
two, the encounter could create a time paradox, the results of which
could cause a chain reaction that would unravel the very fabric of
the space time continuum, and destroy the entire universe! Granted,
that's a worst case scenario. The destruction might in fact be very
localized, limited to merely our own galaxy. In Time Cop they say
that coming into contact with yourself in the past that you could
wipe out your own existence and in fact whenRon Silver's character
bumps into his past self he vanishes from existence.

Taya:
I have just had a thought. Dumbledore always seems to know what is going on 
at Hogwarts, could he therefore know (or have seen) Harry and Hermione in 2 
seperate locations at the same time? Then he must surely know they had gone 
back in time, and this would probably lead him to thinking it was he who 
sent them back, owing to how seriously Hermione took not breaking rules.

I will also mention (carefully, as it's not mentioned in the books but we 
can speculate!) that it may be possible that some of the gadgets in 
Dumbledore's office, keep track of all things at Hogwarts, students 
included, or indeed that he may have a Marauder's Map himself.
