`Big bang`?
Question: Time moving forwards, but what about moving within the opposite direction i.e. looking surrounded by a mirror, or have I get it wrong?
Answers:
According to Stephen Hawking, time has 3 discernable arrows - thermodynamic, cosmological and psychological.
There is no intention in language of physics why they couldn't all run backwards. Lots of scientists have a sneaking suspicion that that at some point in the adjectives, there'll be a "big crunch", where the universe contracts put a bet on down to a point of singularity again.
If that does happen, afterwards it will mean that the cosmological arrow of time have reversed. The big question is whether the other 2 would as all right. Could the universe exist when tomorrow comes before today?
Who know? - not me. But it's a fascinating subject.
Prior to the 'Big Bang' in that was no time, so it couldn't hold been moving backwards (at smallest, not so far as we know )

Hmmm... I'm not exactly sure what you are asking. The big bang is the a idea of the universe's creation... not about the direction of time. Also when you look into a mirror time does not move backwards. Perhaps you could explain contained by more detail.
yeah its wierd aint it. if we could go backwards, surely we could save on going forever. ie if we went backbone 999999999999999 billion trillion milleniums and stopped..i wonder what happened the time before. working on this thought, how did we make where we are very soon.
i must be dopey, coz it is blowing my mind!
oh yeah i think the big rap thing is a nouns of codswhallop.
very fitting question ..never thought of that concept..Einstein's argument ...Time and mass are interlinked.. A forward motion creates a backward motion..so I suppose the possibility of time contained by reverse could be able to ensue..but if it does it will take copious years and many theories to prove it..by that time man will any have no time moved out to find out or they invent a time machine to prove it..
Time is not reversible - you can slow it down and even stop it if you travel hurriedly enough, but if your speed exceeds C you will quit the Universe and go elsewhere. As one and only zero rest mass particle can achieve C and nonzero rest mass objects can never finish C, not can leave our Universe by speed. If they ever carry round to building a time machine you will one and only be able to move about back within time as far as the point in time when it be switched on. So everything that has happen so far can not be revisited.
I noted with interest that above someone have said that there be no time before the big tap. That is now wrong - M Theory have our universe as one of many (possibly and infinite number of) Universes produced as a result of 10D 'Brane' collisions occuring surrounded by an 11D 'Bulk'. Each collision sporns another universe and theory would suggest that nearby are some 10 to the power 100 different types of universe (each with its own personal set of physical constants in operation eg speed of muted, gravitational constant etc). Our Universe is a 4D Universe embedded on a 10D Brane. Clearly time existed formerly our universe did. Time might be a very special dimension indeed.
Time and space have no direction. Time is proportional to mass.The higher the mass. The greater is the contracion and compression of space around the mass. All of space and as a result time was compresed into the Primevil Atom at one time. If that make any sense.
There is a theory that the universe will verbs to expand untill one day, it will collapse pay for into itself and time will run backwards.
LOOK WHEN THE BIG BANG EXPLODED THE FORCE WAS SO GREAT THAT THE FORCE IS STILL CAUSING OUR PLANETS TO MOVE OUTWARD WHICH JUST LEAVES A HUGE SPACE OF NOTHING IN THE MIDDLE OF THE UNIVERSE.
EVENTUALLY THE BIG BANG WILL COMPRESS ITSELF (JUST LIKE AN ATOMIC BOMB) BRINGING THE WHOLE UNIVERESE INTO THAT TINY SPACE IN THE MIDDLE AND THEN OVER TIME THE BIG BANG WILL HAPPEN AGAIN FROM HAVING SO MUCH FORCE WHICH WILL CAUSE A NEVER ENDING CHAIN REACTION GOING ON FOR TRILLIONS OF YEARS.
AND TIME CANNOT BE REVERSED NO MATTER WHAT UNLESS U CAN FIND A WORMHOLE SOMEWHERE IN THE UNIVERSE NOTHING I MEAN NOTHING CAN REVERSE TIME
