40yrs ago my physics teacher was insistant that you couldn't travel faster than light and drew a car on the blackboard doing a right turn, a right, a right turn then crashing into itself saying you cant be in two places at the same time and whilst i agree with that and i know others wouldn't the fact remains you wouldnt be crashing into yourself you'd be crashing into the light from yourself two totally seperate things, was that a poor analogy or have i got it wrong? also is it right to say that if i syncronised 3 clocks seperated 2 by a light year and kept the third with me that no matter where i went all 3 would tell exactly the same time? obviously if i stood by one and looked at the other it would APPEAR to be 1 yr late but the actual clocks at that moment in time would be the same. apparantly traveling at speed alters time, persoally i'm not buying it regardless of the maths and prefer to believe its simplier that that but i'm a 55yr old plaster so simple fits. is there a specific text or part of general relativity that would help me understand that nonsese cheers

yeah i dont really get the spacetime thing i know its pretty and scientists say the maths work. does an object just warp specetime and the effect on other objects incidental i've heard odjects remain at rest till acted on by a force so could a blackhole for example pass within inches of me if i were at rest? does warping spacetime warp the matter within that spacetime? in which case wouldn't that be considered a force. a little knowledge is a dangerous thing, help make me harmless

i'm not saying queen vic didn't exist i'm say she dosent for me to meet her would mean she would have to exist somewhere in time and space not only that but every moment of her life would have to perpeptualy exist as would every every moment of everybodys life and every event that ever happened in the cosmos since the big bang no matter how small, to phsically travel it would require that wouldn't it? is it likely they still exist? can you interact with something that doesn't and wouldn't it be nice if elephants did? no, human memory is as irelivant as a goldfishes. perhaps my problem is i'm not sure what time is. is it the comparision between events having "time" to do something is completeing activity before another has finished or is it simply a record of events "memory". to me it seems at best time is instantanious but certainly doesn't come into being ahead of an event although the machanics for comparing or recording would already need to be in place. perhaps thats my problem i've as good as said time is there irespective of anthing else events merely give it scale, i should listen to myself cause no one else does and i have no idea what GR is. general realtivity? in which case i really have no idea!

is it possible that anything that proves time travel is in fact proving something else? the events from the past no longer exist the information from those events do but the events thenselves dont, the events/information to create the events of the future exist now but future events dont. is there any room in phyisics to interact with something hat does not exist? if you slow down events close to yourself whilst things around you carry on at a faster pace and then you return to your wider suroundings where more events have occured you havent travelled in time, you didnt go anywhere, the people around you didnt lose sight or contact with you, you simply did less than they did and entered a form of suspended animation, is thats whats meant by time travel? would speeding up/slowing down events give the illusion of time travel? for example say gravity was a reactionary force and so variable and affected by speed would flying an atomic clock around the world have an effect on it. obviously i dont know enough about gravity to say if thats possible just curious also can anyone say for certain that gravity isn't a pushing/compressing force rather than a pulling /towing one? i like to thinking 7 billion people on the planet and i'm the only one whos got it right and if it were variable would that do away with the need for dark matter? is it fair to say time is nothing more than memory that would happily exist in an universe where nothing happened if you remembered nothing happened it wouldn't have scale but still exist conversely not exist in a universe of infinate events if you didnt remember those events but then could that universe exist if nothing knew/remembered the rules? the only way to travel back in time is to remember the events of the past and only way to travel forward is to predict future events the only universe where you can physically travel in time is one where elephants fart butterflies.
