No.. I still think going back in time is not possible it's not meant to happen. it is like unraveling a ball of twine.. . you can unravel it but when you try to whined it back up.. it never goes back the same way.... therefore too much to go wrong..... the universe is all about forward momentum.. planets orbit they spin... things are always in movement..... always forward..... leaves fall off in the fall to be renewed in the spring.... you can collect the fallen leaves.. put them in a scrapbook as a reminder.. but you can never go back and insert them into the tree... I wonder if maybe apples and oranges crept into this convo somewhere along the line. If the issue is "Can one travel back in time?" just using some of the examples given, leaves fallen from trees, posts entered, witnessing light from distant stars, etc., it's obvious that travelling into (or, at least, being able to view) the past is a possibility. That's the 'apple' part. The 'orange' is "Can one affect the past?" and that is, most likely, not a possibility for us, just now. And if one tosses in the 'grape' argument regarding a Supreme Being not being able to change the past, it really falls apart for the religious amongst us -- it's Easter and many of us are celebrating the ultimate example of changing the past, Christ's resurrection. It gets even murkier when quantum effects are tossed into the mix. But, that's a fruit argument for another day (or thread).

If.. mankind are any.. thinking being..
could possess.. the power to influence the past.. to manipulate the past...... they could manipulate the beginning.. of everything...... personally if I was to created the universe.. the first thing I would do. is make sure no one can I undo what I have done.... . . |

no, to both... we are here and now, no matter what... leaves falling, looking at billion year old light, celebrating something that may or may not have happened in the past are things we see or do in our time, which is the here and now... |

personally if I was to created the universe.. the first thing I would do. is make sure no one can I undo what I have done.... Doesn't that negate progress in a lot of ways? (Ack! I'm too new here to figure out how to pursue your thoughts. This question is so off-topic, but your position intrigued me. Sorry, y'all.) |

Ok.. problem 1.. top magnet bottom magnet... a steal nut suspended between the two of them... floating in mid-air.. held by the magnets.. pull and pull....... now.. would that nut contribute to the weight.. overall.. it will not contribute to the overall weight as Weight= mass*gravitational constant. here in this case g will be zero. hence weight of the nut will be 0. |

I think time travel works this way...The faster you go in access of the sped of light then time slows in your constant,that time isnt relevant to eaerth time

problem 2.. I have a 10 ton train sitting on the tracks.. I walk up to the back of the train.. and push against it with my own body weight.. the train does not move.... now I float that same train.. above I track of magnets....
. now can I push the train with my own body weight....? . |

and why I believe you can not travel back in time.. and influence that time..... imagine if somebody could harness.. the power of a black hole..
theoretically they could go back in time.. implement a black hole.. 10 seconds before the Big Bang occurs..... the beginning of the beginning that is...lol... well you see where I'm going with this..... End game not good....lol.. |

and yes I recognize the paradox.. going back 10 seconds before the beginning of anything..lol.

not even if I put my shoulder into it..?.lol

how about if i surround the whole thing in a vacuum chamber.?
