Connecting People [by Time] |
0 | ||
Hi all ^^ this is paduman typing xD all can see that i guess This is not an advertise ment of nokia connecting people etc I just wanted to give somecatchy title :3 So, I wanted to discuss why we cant make a time machine that goes back in past . Lets take the method of contradiction. let there be a person named yeda[meaning fool]. He is frustated yet a genius and has invented time machine he has lost everything in life and wants to destroy all. He takes a gun [lets say dragonunov] and goes back in time about 2 days earlier. He shoots his past and his past dies. let his past be known as yeda P and present [the time he came from] yeda f Wait who the hell is yeda f then if he died 2 days ago he cant kill his past since he has died ? yeda p is killed by yedaf but since yeda p is dead there cant be yeda f and if there is no yeda f yeda p cant be killed ! Time cant sustain this confusion. Paradox shall be created [ please dont ask me what paradox it wasnt really understood by me 2] Time will never let this happen. Hence a timemachine going to past can never be created. Lets take an more easy way to say this do u see time travellers? no? y since its not possible. lets say u make an time machine going to past what will happen? You or someone shall try to go and change the past like make an telephone before grahambell and be famous. Hence logically its not possible to go back in past . But, As proposed by great scientist Stephan Hawkin we can travell in time to go in future ! Thats all wish u guys like it all are free to post comments and give other hypothesis on same topic |

Bro, have you heard about space-time flow?? Imaginary and real time?? Sticky-end?? well ur theory fails to do so,, but (Do not feel hurt) and if u propose such a theory.. u should even have ample evidence to do so.. your theory is good.. good thinking but it fails to convey the very necessary point... u see... The laws of Physics do not know the set of protocols Time follows.. So naturally, We do not know how Time flows... Let us see what time is in the first place..Is it a steam engine??? or is it a railroad track? Maybe it has loops and branches, so you can keep going forward and yet return to an earlier station on the line....Nothing like time and space confuses, troubles and surprises any sane human being... this is bcoz we dont even care about those 2 things..Now any scientific theory to be accepted needs to do one thing... this approach is called Positivist approach of Science wherein the proposer shows a mathematical model of his theory (Here, we need a mathematical model of time) which explains various postulates concerning his proposal and even explains and predicts events of the future precisely.. then the theory is accepted ... even though it is not correct.. I too believe this approach, Stephen Hawking does, Newton and Einstein did too.. For Newton, time was merely a background like a background in a fish tank.. various events took place in this background but that didn't affect the background itself... (This is written in his book called 'Principia Mathematica').. time was separate from space and was a railtrack (For Newton) which extended to Infinity on both sides.. (presently we define Infinity as a number greater than anything u can think of i.e suppose n, then i= infinity is greater than n .... i > n )... what does this basically mean that, Time was eternal for Newton.. means it existed even before the existence of the universe! Now one thing that surprises cosmologists is... WHy was there this infinite wait for the creation of the universe.. if time was eternal.. why did the universe take such a long time for creation??? whereas contrastingly, If the Universe existed as eternal too... Why isn't everything in thermal equilibrium(Thermal equilibrium is a state in which all the bodies have reached equal levels of Heat and show equal temperatures) by now??? Both these question contradict themselves.... Now For Einstein... well Einstein shook the Laws of Physics entirely.. when he proposed his theory of General and Special theory.. Introducing a concept called Space-time.. and from 1915 since now.. our mathematical model of time is based on his theory. NOW.. this is the turning point...General relativity combines the time dimension with the three dimensions of space to form what is called spacetime..!!!! this theory is based on 1 simple concept that even a 6 year old knows! Gravitational accn. and Gravity! What happens in his theory is, the effect of gravity on matter and energy in the universe warps and distorts spacetime, so that it is not flat. Objects in this spacetime try to move in straight lines, but because spacetime is curved, their paths appear bent. They move as if affected by a gravitational field. A simple example to prove this is : imagine a sheet of thick paper, one can place a large ball on the sheet to represent the Sun...The weight of the ball will depress the sheet and cause it to be curved near the Sun...If one now rolls little balls on the sheet, they won't roll straight across to the other side but instead will go around the heavy weight, like planets orbiting the Sun... u see?? but do not forget this example is 2d whereas spacetime isn't ok?? i shall speak more to those who are interested... So to sum up, Time has a shape! and one cannot only curve time without involving space in it!.. Space, Time and Space-time are different things.. ok? but all of them are interelated! :) Hope u understand it... ur theory according to me has spark.. but u need to involve much more content in it! :) plz understand Padu.. |

yay my thread is immortal xD also the theory is posted can be more seen in depth by viewing the show THE UNIVERSE [time travel] |

Paduman a dit : Padu, I do not rely on shows for my information they sometimes make up things to fool people, Books are a great way! They convey the very feelings of the writer! and even help you to Imagine and visualize the words in your brain, which the T.V fails to do... cos it already transmits pictures making it a similar process like "spoon-feeding to the brain" xD, Try Books too Padu :) |

Winjid a dit : Perfectly explained. I also prefer books more. |

a dit : ~The 10th Doctor, played by David Tennant I'll keep to that theory, until there is actual proof against it. :P |

Well, there is a theory that I really do appreciate, and it is called "Many Worlds". Suppose you have an event, with two or more outcomes. Time has just split into the output. Then those parts that are now "the present" divide into even more branches, and those into even more, and so on. If you somehow travel back in time, and kill yourself, you will be dead in one dimension forever, in the second dimension you live a normal life without even knowing about the time machine and in the third dimension, you will have a rush to kill yourself... travelling back in time. This means that if you warp to an alternate dimension, the Big Bang is still there, however things are different. Even if you travel to the same looking dimension, only one molecule off, over time the entropy would increase... relative to our universe and vice versa. This is why warping through time is possible, but requires energy. A lot of it. If you want a custom universe, to be around 99.999999999999999% accurate, you would need a lot more energy than warping to a random universe or travelling to a universe less precise. This theory is SO amazing at explaining quantum mechanics and a lot more stuff, that its one of the most uplifting theories there are. Kostia out. Dernière modification le 1449497280000 |

Well As a physicist, I have heard about this theory, what it basically implies that all possible outcomes in this world, when an input is entered should be considered.. not only considered but actually are real! Hence causing parallel Universes (With the action not chosen) to be formed which again implies that Infinite number of Universes already exist (Since infinite possibilities of choices could have happened in the past and are even happening now).. Well this theory eliminates major paradoxes... but since this theory is a quantum interpretation it is governed by laws of quantum physics.. and as far as time flow is concerned... It can't fly backwards.. That simply means you cannot go back to the past... Time can bend, be made slower, distorted.. but never fly backwards... The laws of quantum physics and numerous paradoxes ( The Grandfather Paradox the most popular one) state so.. but yea, according to this theory.. there are multiple yous in different parallel universes which you don't know a thing about... and even if a time machine could be made.. It would never be able to take us in the past.. |

Wait Winjid does that mean there are many me's in parallel universes which I don't know about |
0 | ||
Chuchuchacha a dit : In simple words according to the many worlds' thesis... Yes there are multiple yous in parallel universes.. How? Why? is that what popped up reading my earlier statement? Read everything mentioned above concerning Many Worlds' thesis by Kostia closely you probably might get your asnwer.. if you still didn't just let me know again :D |

You guys have such a deep understanding regarding this. I fail to comprehend some of your contents. But here's my thought, say you were to go back in time and confront your past self, shouldn't you have been confronted by your future self back then? Like each second's a film frame and therefore, events would be inevitable. This is just my thought and after sometime, saw the film Predestination which pretty much managed to share with me the same view on time and somehow, also got my mind all messed up. Take a look at this billiard ball: Somebody a dit : Sorry for the bad explanation, I don't really know how. Dernière modification le 1496316360000 |

Man this is going to be hard without pictures.. Please bear with me tralie What you're asking is a well known paradox, I even briefly mentioned it above while speaking to Kostia.. Its called the grandfather paradox and is basically a problem that arises when travelling in the past. One thing must be made clear about time travel though, "You simply cannot travel to the past." I'm not saying this because of the paradoxes occurring due to past time travel forbidding us from going there but presuming on the basis of the structure of time flow. Mankind hasn't gotten the power over time yet. Time moves only in one direction.. forward. This direction can be altered but cannot be reversed. So problem solved? The ball wouldn't be able to exist in the past in the first place because it never left the present. Who am I kidding? Where's the fun part.. Okay let's just say somehow you go back in time and trigger a change in the tempo of the universe there. What happens then? You create a new universe. A parallel universe. In fact the moment you stepped into the time machine you created a parallel universe. All the decisions taken there will only affect that set universe. This is called the many worlds interpretation. In fact, this theory states that infinite universes already exist with every possible decision taken and existing in their set universes. This is just a theory after all, but it does debunk many of the paradoxes created due to time travel. Another way to look at a solution is to just follow the structure of time flow despite the paradox.. Let's say the 8 ball goes into the past, touches its former 8 ball, alters its path causing it to not get into the time machine, which in turn causes it to not touch the past ball, which in turn causes it to go into the time machine, so on.. These are two events represented as one in a single frame of reference. We can call this a superposition of time events where both the events exist in that same timeline depending on the actions taken therein. Waves and particles do this in multiple phenomena, the double slit experiment is proof of this. This even removes the paradox to some extent and limits the time travel theory to one single world. Anyways, I hope I helped Tralie.. Please, let me know if I failed to explain myself simply. These days I don't get much time to even type what I like about but I really wanted to share something about this because its exciting to me! |

Oohh, thanks for explaining, winj. |

About the many worlds theorem, it feels like a "5th dimension", as if time branches to another dimension. This really feels like an "extension" to the time dimension for me, if you obviously consider that atoms and particles behave in another 6th and 7th dimension that may explain their weird behaviour that follows probabilistic behaviour in a 2d complex plane X 2d complex plan. The probability density explanation of quantum particles could be a simple "presepctive" on how they work in 2 more dimensions linked to them in my opinion. Looking at the "infinite universes" as branching from the 4d representation of spacetime to construct a whole 5D existance (I said existance because well, it says universes fo spacetime so yeah) is quite nice to think about, nonetheless. I also wanted to say, if you ever thought of a "MULTIVERSE TIME" and we encounter problems, we need to think of a 6D existance to quote on quote "fix it" I think the theory is just an abstract way of thinking, more than anything possible.
