Yes, that was also covered by that physicist. Baiscally, both his black holes would weigh about a billion metric tons each
please don't continue to beat the horse |

SO if you could travel through time you would try to kill Hitler befor he was anything important? what if that would produce that russia became more powerfull than the US and conquer all? |
why would you want to do this anywayz? :D |

njizer,
can you explain in a bit more detail in regards to mutiverses, and why you cant travel back to your original Universe? Im not trying to beat the dead horse, im just curious about this notion thats all. I always thought theoretical physicists say "you cant change the past" due to an overwhelming moral issue and the fact that one change in a universe will ripple onto other ones as well. The topic of multiverses is a bit complex, even when trying to explain to someone about the Grandfather Paradox hehe but I havent come across an explanation as to why going back to your original universe is impossible. :) |

Well, according to Hawking, there may be two possiblities to time travel that would provide resolution to the "you can't change the past" paradox. One he calls the "consistent histories" approach. That theory dictates that even if space-time were so warped so to render time travel possible, the happenings in space time must be consistent to the laws of physics ... meaning that history has already recorded your travel to the past, where no grandfather paradoxes have happened, and where you did not change recorded history. This may be a violation of free will you may say, however, given a grand unified theory that governs everything, it also would determine your actions, therefore free will is illusory. We say we have free will because it is impossible to predict what a person does given its complexity, however, if a person goes back in time we would be able to predict what they did since it is a part of recorded history.
The second theory is the multiverse theory that I guess is somewhat similar to what happened in back to the future 2. However, I think the thoery is that the number of multiverses there are take into account EVERY single possibile history with a set probabilities. Therefore regardless of what actions you decide to take, when you go back, you automatically jump to the appropriate multi-verse whereby what you perceive as actions undertaken by your own free will were predetermined inevitabilities associated with that multiverse. I think he has some other theories as well but I don't know them off the top of my head without hte books in front of me. |

occ covered it pretty well. As to getting back to your original universe... well, its probably possible but it would be a ing monumental acheivement to do so. If I'm correct, all the universes are floating around next to each other in 5 dimensional space (imagine a sack of marbles, each marble is a universe). So basically, here you are in a parallel universe somewhere between all the other universes. Not only would you really have no clue as to WHERE your original universe is, trying to directly point yourself at it and teleport there (it also being an unfathomable distance away) is pretty much impossible. |

a kernel of insight for a grain of salt. its probably there, i don't have bloody time to shift through a desert of it.
a simple logical question of: if he comes back and fails to stop it, whats the point of doing it? he's just a one-man show up against the world. he couldn't or anyone else could stop it if wars did happen. |

akashic records will know in theory. this compendium of all databanks would have the records from point a to point b.
who do you mean by "you"? couldn't another non-human lifeform achieve it? you're basing your opinions on current theory, tech, and human evolution. outside these contructs, its very much possible. |

| if you think for a minute, the idea of different universes is weird and creepy. like, you could been already killed in other universe or not to exist at all. i wonder what would happen if someone went back in time and stopped the meteor that killed the dinosaurs. |

The multiverse is constantly expanding if current theory is true. Every time an event happens a new universe is spawned to account for the possibility that it *didn't happen*. This is happening on such a small resolution it's literally unfathomable to contemplate how many multiverses there were even one second after the universes creation. At least that's my understanding. I don't even think travelling backward in time would be a linear thing and if you ever time travelled your current universe would be forever forsaken, a simple memory in your fading mind. In theory there are universes where humans never existed etc etc. It's all pretty mindblowing but it's just a theory. We live in what we percieve as the "most propable."
Although it's pedantic in scope there exist universes where you won the lotto when you bought that ticket etc etc. Pretty interesting? |

| so.. there are an infinite number of universes? freaky, like if this one wasn't already big enough |

Sure, another lifeform could... hell even humans could. I'm just saying its so incredibly, inconcievably difficult that the odds we will ever possess such technolgy, especially in the year 2036 after a global nuclear war, and especially with a little 2x2x6 box that he claims is his time machine, are pretty much a dead on ZERO. |
