The same thing happens in our every day experience, it is just that the effect are too small to be noticed. It turns out their is some sort of inverse relationship btw change in time and change in space. Look at it the way, assume you have 100 units of an arbitrary energy like thing called space time SP. You cannot have more than hundred, and you can only use it in two forms A. For changing your Space or B. For Change your Time. You keep your hundred units SP in form of some Velocity in Space and Some velocity in Time at any point in time. If you convert the whole 100 SP to velocity in Space by accelerating yourself, you will be changing position in geometrical space at a rate equal to the speed of light C. If you convert the whole 100SP to velocity in time, by totally de-accelerating yourself, such that you do not change position at all in geometrical space, your velocity in time will be maximum, ie. your experience of time will be at the fastest possible. This state corresponds to being at rest with reference to the space time. Note that cause you are on earth, and the earth is spinning as well as orbiting the sun, we are never at rest. So we are experiencing a state in between max. Space velocity-speed of light, and maximum time velocity, but we are closer to the state of maximum time velocity, since the earth spin and orbiting velocities are very small compared to the speed of light. When you enter an airplane, you velocity geometrical space velocity increases, so to conserve that 100 SP, your velocity in time reduces, so your experience of time seems dilates a little in an airplane. Infact this has been proven with atomic clocks. So back to how do you travel in time |

A. So for the traveling option A. Literarily, it's not like you are traveling in time, it is more like doing something to make you arrive late in time, with reference to what should have been your future. A classical tale is normally used to explain this, consider two babies, twins, born exactly at same time, at age 20, one becomes an astronaut, the other a teacher, exactly at on their 20th birthday, the astronaut blasts of to some distant planet on a fast space craft. All through his journey, he keeps time with his watch, and returns to the earth exactly after five years on his watch. Except, that all the while he was on the fast space craft, time dilated for him just like the aeroplane example I gave. Also he visited a planet that was orbiting and spinning some 120 times faster than the earth. He spends five years, but when he arrives the earth, 40 years has passed on his brothers watch, while he is 25 years, his twin brother in 60 years and already has grand children. That is the sense of time travel we currently understand |

logica: If indeed you want to learn and not just being sarcastic, then Google what Einstein's Theory of Relativity is about; and of course you will see the Mathematical equations which predict these facts. And yes, they are facts as they have been backed up by experiments long before the Large Hadron Collider (LHC) existed. Of course LHC has been useful in recently proving the existence of the "God Particle" or Higgs Boson which Peter Higgs had predicted.I'm not been sarcastic...believe me. I have read almost everything there is about this theoretical nonsense and still couldn't grasp it. Explain to me how they came accross the knowledge of how matters and their properties will behave in respect to both General Relativity and Special Relativity. I have tried to read to understand M-theory, String Theory, Superstring theory, dimensions, Theory of Everything etc but I get more confused but elated knowing whatever they intend to achieve with all these theoretical jargons juting out of the physicist paradize can be and have already been achieved through YORUBA ADVANCED SCIENCES for instance if you want I can let you in on how to achieve a simple invisibilty shield using component from nature. This is the extent I can go on this thread unless you provide me a comprehensive breakdown of those theoretical concept from physics. 1 Like |

B. Change of Location. For the second more complex idea of changing time by changing reference position or location, it has to do with the idea of concurrent events. It turns out that concurrency is as elusive an idea as time it self and depends on your reference frame or place of observation. The fact that all observers see light to be traveling at the same constant velocity C muddles up the idea of what is happening concurrently and at what time. Am not going to go into big details about this since one would need diagrams to explain, but the button line is that for some one sitting say 100 light years away from the earth, based on the light reaching him from the earth right now, and the projection of its travel in space to reach him based on his own time experience, what could be happening right now on earth from his perspective could likely be the birth of your great grand mother, or the death of your great grand child at a ripe 90 years of age. Hence by changing location on space, we could realign ourselves with events in time, but it is only noticeable with great changes in distance. But be assured that when me and you were sitting on a bench at eagles square, and observed a gun shot, and a boy fall off a bicycle concurrently, we both agree the events are concurrent, but there is a minute difference in our persecution of the events concurrency due to our space separation, the larger our separation in space, the large the difference in our view of the concurrency of the events, Infact, if we were 100 light years apart, we surely will not agree that the two events are concurrent. In summary, because time is defined from our experience, it depends on our reference position, hence becomes difficult to be given a static definition. It's just like every single person carries around a distinctly different definition of time by virtue of their location in geometrical space and the velocity in geometrical space. Beyond what we know from science, I do not believe relativity has truly or totally defined time, it merely scratched the surface, personally I think time is the shadow effect of the remaining 6 out of physical 9 of the 11 dimensions postulated by string theory, where we only perceive 3. |

Let me also add, that past and future are relative terms that depend on not just your position in space, but also the angle at which you are project into time. Hence, what may be in the past for you could very well be in the future of some one way across the universe. So saying travelling back is impossible is pretty immature. Consider a cuboid lump of soap, you are. Slicing into two half past and future, the parts that fall into the past half depends on the point you slice in, and the angle at which you slice it |

ghostofsparta: Explain to me how they came accross the knowledge of how matters and their properties will behave in respect to both General Relativity and Special Relativity.That's like me explaining how Messi, Maradona etc came across the skill you see them exhibit. It is both talent and work. They did it with mathematical ingenuity and inborn spatial analytic reasoning. |

Any object that can emit light particles and gain it as thrust can move with the speed of light. Alternatively, any object that can repel light particles can also move with the speed of light. ...but time will only slow down when you are high on weed. 1 Like |

robinicule: when u look at the sun u r looking @ 8 mins ago, if d sun dies all of a sudden, it will take us abt 8mins to know......and according to einsteins theory of relativity, if u can travel infinitely at the speed of light, time tends to slow down for u, everything around u will pause. anoda example is space time. space time is slower than time on earth, because there aint no gravity in space, d lesser d gravity, d slower d time, dats y dose people leaving on a cliff, time passes through them slower because they r farther to the earth's core (lesa gravity for dem)........my token, time travelling is very possible, dere just might not be equipment for it yet, but arbitrary theories claims it is possible.....our naija micho kaku,...you are on point bro. |

Mi amigos time travelling is not possible i.e going forth/back in time, however you can travel in time. Humans are actually travelling in time. |

Humans should forget about time travelling, every effort to build the technology is always thwarted and will always be, yea thwarted for a reason "to keep away from human what they are not meant to know". Remember earth is more than 4 billion years that should give y'all some insight to your unattainability of it. Let it remain a fantasy. |

come to think of it if time travel were possible we should have received visitors from the future, and if you travel to a time you weren't born, logically you are not existing then, your parents weren't even born therefore you'll die. |

Psylas: i know it's impossible to travel faster than the speed of light, the question is whether time travel is real or fiction,Excluding the idea that going faster than light speed will make you go back in time, time travel is definitely real,very real, however, it's hardly in the sense people paint it. Future is simply living in events earlier than one would have under normal earth velocities. That's easy to explain with time dilation, all one has to do to live events earlier is to slow down below earth velocities, say jet to space and go into rest or stationary state, or the equivalent of free fall wrf to space time constant. In that sense you could either arrive early to future events with time contraction or arrive late to future events with positive time dilation. In the sense of already occurred events, I can readily think of ideas for reobserving those events, but not reliving them. Reliving an event is definitely going to throw in a lot of entropy, hence a need to restablish a new version of equilibrium. However, some ideas already exist which postulate that all things have already occurred in a singularity, we are only going through the illusionary experience of living through events serially. In this sense, time velocity is just like space velocity, and should be reversible. More knowledge will come with time I guess. |
