it is never possible.
because then there must be people from future. _________________ God is one and only.

What if it's like quantum mechanics? Maybe we look at Schrodenger's cat, and assume that all moments of space-time are indeterminate (from your perspective) until you observe them.
Then you can go back in time, but only to moments that are indeterminate from your perspective. |

| Relativity doesn’t say anything about moving backwards in time. Time dilation near the speed of light or around black holes only slows time for that observer. Einstein never said that time was a spatial dimension and had a reverse gear. That link is complete conjecture. |

I don't know, didn't Einstein say time is relative? So if you was around the black hole time would seem normal to you, but if you are not moving the same speed through time as someone on earth. That is a form of time travel is it not.
I mean, time dilation has been proven. Satellites orbiting the earth are actually traveling through time at different speeds than people on Earth. I like to think of it like that anyway. |

Yes time dilation works, but time travel, moving forward anfd backward, does not. Time isn't like a spatial dimension. You can't 'turn left'.  |

Why not? If space and time can be warped by gravity then surely there's a possibility of one day being able to navigate them? Doesn't Einstein's theory allow for worm holes?
Look at me getting my red dwarf on, i'll be talkin about hard light next lol. |

With wormholes, if you have one entrance in the present and you send the other in a spaceship near the speed of light so that it returns to Earth say 100 years in the future, then spacetime is warped and you could go from that future into the past (our present). What they don't tell you is that passing through the wormhole from the future may take you 100 years.  |

Thats the worm hole vaction I had planed off the list then. |

If Christipher Reeve wasnt dead he could put his Superman outfit back on and fly us backwards till Einstein Time and ask him to come back to today and discuss it but we cant.. So why not fix the problems we can first and maybe we'le come up with something along the way that may also help here later when were like 100 years more evolved, and survived a Planets Global Warming effects, And can actually work as Unified Planet instead of a bunch of countries that want Top Billing for something that Needs to be done Or Else!... Sometime I think were worried about things that are beyond or need to know.. Like Time travel and God (if there is one) Creation of the Whole Universe and Others if there are outside the one we know and see, (The anti White Universe "Myth")... I mean come on It's going to take Hundreds of generations to even begin to figure out how this who thing started.. OK Yea it started from Dust.. Where the dust come from.. Its the chicken & the Egg.. Is God watching all this under his +14x Holy Microscope documenting everything thats happening like a kids High School Science Experiment.. If not were did everything start, How,Why.. Again things we dont need to know. We Cant change these things. we have no power over these things.. It May help us figure out events to come in some way but not until Science catches up with our Egos about how everything that has a question in the universe is owed to us because were human.. lol.. Wrong.. Were Atoms in a giant being known as the Universe easily removed with a sneeze or shower, just needing to help ourselves live...

| einsteins theories of relativity states that we can travel to the future by moving with a velocity close to that of the speed of light, but it states nothing about traveling back in time, so we would not see people from the future. there are possible but not proven ways to go to the past but they r still theoretical. if u were to take two connected wormholes and take one into the future by traveling at the speed of light u could go back to the present from the future but u could never go futher back then when the wormholes were made. you cuold also take to cosmic strings and colide them together. then you would go around it near the speed of light and u will arive back at the beging before u left, hence going back in time. this is only possible because when the two stings collide it has a radious that is smaller than 360 degres. |

| The problem with worm holes is similar to the problem with black holes. You'd be dead before you got to the other side. The gravitational pull near your feet would be so much greater than the pull near your head, that your body would be torn apart. |
