Travel Across the Time
|
|
Um, hi. I've read from somewhere that when we move faster than anybody else, we will feel as everything surround us becomes slower, and vice versa. I find this pretty much right becoz when I was standing in mall waiting for my cousin, I felt people move quicker than when we walk at certain speed. Is this just my imagination or what? It also says that there was an experiment about measuring the time elapses in aeroplanes and on land. I can't remember for sure what kind of experiment that was. But it seems that the time elapses in aeroplanes is 1/3 second faster than that measured on land. If this is true, can we really 'travel' through time in this universe? Say, if we manage to move beyond the speed of light..

Well, the first part of your post merely describes a difference of perception. For example, if you move faster than everyone else, you'll think that everyone else is moving slower than what you're used to. Naturally, if you're slower than everyone else, you'll think that everybody is moving faster than you do. You can see it's your imagination, but it's probably just a difference in perception, since you were standing around. As for the aeroplane experiment, I wouldn't have an answer to that one.  |

| the speed of light is basically the speed limit in the universe.....something about gaining too much mass when u go too fast i dont really know... y dont u look up that einstan theorem or w/e for more info... its kinda werid to think about it... technically things up in skys we see that are lightyears away are probably years dead anyways. so basically if some alien from this "planet that died like 100 years ago" to earth faster than the speed of light. Then he looks back at his planet and hes like OMG MY PLANET IS STILL ALIVE and he takes a powerful telescope and sees himself on the planet taking a shit or something.. isnt he like technically back in time? |

I think the theory said, when we enter the speed of light, our existence becomes slower than our surroundings, right? So... We're the ones that become slower, and everything else goes faster than us. Maybe if I become an astronaut and travel to the other galaxy then come back to Earth with the speed of light, I can see the face of my great grandson! And if we manage to surpass the speed of light, maybe we can see heaven! lol

| well the einstan theorem is saying you can view the future instead of past but if we look into the stars, we are viewing what happen millions years ago because the light of the image strike upon us late (considering that it's millions of light years away) and if we travel at the speed of light (even in space) time still flows but only slightly slower. for example, if one of the twins travels around the world at the speed of light while the other travels normally, they would only be maybe less or about a year apart in age. |

| We often think that we're "moving ahead with time". But what if we're really just standing still, while "time is moving in the opposite direction to us"? This is Einstein's concept of relativity. Therefore it's possible that we change how the time is moving, and maybe we can move a different way altogether! |

Short answer: Probably not. If so, then only forwards, not back. Long answer: Think about being cryogenically frozen, then thawed years later. Have you traveled through time? There's your answer.

this is all einstiens thoery of relavity. Pretty much if you are traveling at 20 mph and a train comes past you travling at 40mph.. it would only seem to be going past you at 20 mph.. this is relavity. Einstien also figured out that the speed of light though never changes, no matter how fast you are moving the speed of light will always appear to be at its constant.. its not relative. Also when you go faster and faster you gain mass. Time really isnt anything. It is a concept in which we utilize to help visualize rates of change, and not being a physical thing you cant travel through it, forwards or backwards

hmm... i think we can go to the past but not physically.... if u like to look at the past u should look up into the night sky.... another way to look at your dreams cuz those are memories in ur brain.... another way is to make those time capsules things....(u can try to put ur beloved pets there too....LOL) -Laughter is the best medicine ......But seriously i think we cannot travel in time..if some 1 did then we have felt its changes(although i think some 1 already did cuz how do u think were dragons and demons come from?) sides ive watched in discovery that there is a guy currently building a "time machine"(Note: i dont know about the details on how it work but it involves light mainly lasers)

Across the time... i can't say that for sure. But if you think about paradox of time, it will confuse you. Example: You back to the past and kill your mother, you will not exist. But if you don't exist you won't able to cross the time and kill your mother. But if you exist you can make yourself dissapear from the world. Confusing..... -_-   |

Hey2, maybe we can only go into the future afterall, but not to the past. Let's see, if we are 'hibernated', we'll feel that time stops for us, but we will still young! Though the catch is, is it possible for hibernation to occur? It needs to achieve absolute zero by the way.. x_x

| u know i dont really believe that we can travel through time (to the future) u see, if we can go to the future that means that the future is already set and all we got to do is stick to our own fate..as if every thing we do are going to end the same..^_^ |

The past is set but the future can be changed. You have to believe in this in order to achieve what you want.

I must agree with ericsolazy give him props.  |

go ask einstein ! if we can do that. can you tell me how we move forward and backward if forward mean you move faster than anybody else. does backward mean you move slower than anybody else? go think!
kill me or i'll kill you twice

*sigh* It's rare for people to truly understand the theory of relativity (of time, in any case). The relativity of time is between a moving object and a motionless one (so, that funny theory about touching a hot pan and having it feel like an hour when it's only a second isn't true). Example: I'm on a moving train. I sneeze once, and then I sneeze again. The time you would measure between my sneezes would always be longer than I'd measure, because I'm in motion. The actual equation is: time (that you measure) = relativity factor x time (that I measure) and the formula for the relativity factor is: 1/[SQR 1-(v/c)^2] We don't notice the difference in times because the velocities we reach are so insubstantial compared to the speed of light. But no matter what, the time that you'd measure would always be slightly longer. As for the airplane experiment, they used highly sensitive atomic clocks. One was put on a plane and flown around, while the other was on the ground. When the clock on the plane got back, they discovered that it was slightly faster than the one of the ground, and by exactly the same relativity factor calculated from that equation. Which makes you wonder... if time is malleable, is reality?

WITH ALL DUE RESPECT AND NO OFFENSE INTENDED WHATSOEVER HERE IS MY OPINION: I'm sorry to nitpick but relativity has no absolute reference frame. I believe you are incorrect in stating that it is "between a moving object and a motionless one." An inertial reference frame is often used, true, but it is not considered an absolute reference frame. In fact, there is no absolute reference frame. We are already time travelers. Except we're traveling in one direction. For those arguing on the basis of faster-than-light travel, it is not precisely known what the exact effects will be. Time at that point, would become imaginary due to the fact that since the gamma factor is (1)/(square root of (1-(velocity of given object/velocity of light)^2))) then we would have a ratio of v/c greater than one, which would result in the square root of a negative number, which results in an imaginary number. Also, as we approach light, we get smaller and smaller, and our mass increases. And the uses are nowhere near practical. Just approaching the speed of light would cause one to be crumpled and I seriously doubt that a practical time machine could be built to withstand the rigors of such speed. The mass one would have would be incredible and the size miniscule. Also, even then, as objects reach light-speed, it is held by many that they become light. So, that would make everything useless: we'd die. Perhaps physicists will eventually send particles back into or more forward into time. (Sending it forward would make it actually observable) But I seriously doubt we can send a person through time. Unless such ideas can EVENTUALLY translate to use... then it is useless... (I am not bashing theoretical fields; I'm merely stating that if time travel proves to be impossible, then there is no point in pursuing it further)

I agree that it is (at this point in time, and probably always) basically impossible to time travel, for all the reasons you stated. I doubt that the theory of relativity was created to question whether or not it was possible to time-travel, but to observe the malleability of time. It has no truly practical usage. Of course, if it's true that time is slightly faster for a moving object, it'd be interesting to do little experiments (which aren't exactly viable, but humour me). For instance (hypothetically speaking), you could put one person from a set of twins on a concord jet and fly them around the world (stopping to get fuel, etc.) but not truly stopping for a whole week or month. At the end of that period, it'd be interesting to see whether or not the person seems to have aged more during that period of time than their twin. (For a more scientific judgment, you could take samples of their cells). Hmmm, this project might be a little more viable on test subjects with a shorter lifespan... an organism of some sort...omoeba?
