Oooh, my head hurts after reading all that! I think I need to go back in time and tell myself not to read this...If I succeed, my post should disappear (I think?) |

I thought up an idea about how to travel through time.(of corse I dont know it it works)
The idea is to get inside an object and let light speed around you)
But when I think about it scares me.
first of all say I want to go back in time 25 years and let the air out of someones car tyres so that when she gets into the car somewhere she wont be in time to get in a terrible car accident.
When realizing that this might work I have a new problem.If you would stay there there would be 2 of me on the planet at the same time so I guess you would have to go back to point of departure.
When you think about that, the reason why you wanted to go back in the first place will have dissapear and I have the feeling you wont know you have to go back to correct this?
The second thing that worries me is the speed of the earth. Your inside of an object that doesn't move. this means if you want to travel a day back or forward your gonna end up sufficating because the earth will be gone a day. So think about air supply.
This gives me the idea that your only gonna be able to travel in exactly a year when the earth gets back to the same place(dont forget the earth has about 365 |

Matzusdog,
You state... "if you tip a glass of water it doesn't fly upwards." That is totally dependent on your "upwards" or point of reference so to speak, is it not?
You also said... "but there is nstill ot enough energy in the universe to accelerate a mass to light speed. even near light speed." Oh really? Then please explain these observations...
http://www.space.com/scienceastronomy/astronomy/gammaray_bursts_010522-1.html
You say that so definitively... like you've went out and measured all the possibilities yourself and subsequently ruled out the possibility. Which we all know isn't the case, you are simply stating someone else's theories (best educated guesses) on the subject. They might very well be very valid theories but there are new and differing observations being made almost daily. The sciences, including mathematics, are constantly evolving, ideas are being discussed today that were previously ruled as "impossible" and that were indeed "proven" impossible by the science of the day. Yet, we've somehow managed to accelerate light passed the barrier by a factor of 300 (possibly) so how can you definitively say that we'll never circumvent the preventing barriers someday? In my opinion it's close-minded to do so and might someday result in you having to eat your words.
I agree with you that mathematics are VERY important. They are the one true universal language. They, like most everything else we know, aren't perfect though. Do you believe that we absolutely know EVERYTHING there is to know about numbers and mathematics? Do you really believe that mathematics are perfect and unflawed and therefore can ultimately tell mankind everything it's capable of (by being mathematically possible) or not capable of? I should hope not as it's fairly obvious that not everything is known about everything from the start. Math has under gone an evolution and increase in understanding over the past ten centuries so much so that even you can't deny that math changes AND grows in understanding continuously.
For example:
3 guys want to share a hotel room and the costs. The clerk charges them $30 ($10 apiece) and sends them up to their room so they can rest. Later he discovers that he's overcharged them for the room, the correct rate for that room is only $25 per night. He sends the bell hop up to their room with their $5 refund. On the way up to their room the bell hop is wondering how he's supposed to split $5 between 3 different guys. In order to avoid the hassle he pockets $2 of the $5, leaving a $3 refund to split between the 3 friends. He does this and leaves... everyone is happy right? Except for the mathematician... the 3 friends each paid $9 apiece for the room ($10 minus the $1 refund) which makes a total cost of $27 ($9 times 3) for the room. $27 plus the $2 the bell hop kept only equals $29 where'd the missing dollar go? In the mathematicians wallet, that's his cut for making you believe that numbers are perfect... 😊
Now that I've rambled sufficiently I'll state that I still stand behind my conviction that breaking the light speed barrier might someday happen, and that there's no ABSOLUTE proof either way as to whether or not it might someday be "possible." Like someone else said, maybe we'll do it outside the boundries of what we know of as "travel" in today's world... but I still think it's a possibility, since we have yet to REALLY PROVE that it's not possible. Theoretical or mathematical proof does not constitute absolute proof, to me anyways. |

There is an excellent if rather odd little movie that exactly details how a relativistic gravity-linked time machine would work called "Primer".
Basically, it works on the idea that gravity and time are linked, so by creating or adjusting gravity, you make a time-like loop in which time can flow in reverse or at a different rate. This obeys Einsteinian theory and makes sense in most quantum physics approaches to time.
Some people might doubt that gravity and time are linked, but try this thought experiment; Suppose a super-race desired our sun, and teleported it instantly to another site in the universe. How long would it take us to know? Classic physics would claim 8 minutes as that is how long the light would take from the sun to reach us to vanish. Actually, we would know instantly - As the Earth unbound from the sun's gravity would fly off at 18 km/s. |

Actually, if the sun vanished right now we wouldn't know about it for c. 8 minutes. Simply put, space is deformed near a mass. If that mass vanished space would not snap back instantly. Rather the adjustment from "deformed" to "normal" would travel outward in all directions at the speed of light. Think of a sheet of rubber with a bowling ball in the center. If the ball vanishes the rubber in the center would snap back and a wave would then start expanding from the center until it reached the edge. It would not all instantly snap back into place. |

I like to react to what DFStuckey just stated.
Like I stated earlier its better to time travel a full year at a time and maybe its even better to travel 4years at a time then you will end up close to where you start.
If matter and time are connected and you travel for example 1/2 a year you will travel through the sun meaning you probably wont be able to get out of the gravitational pull of the sun as you reach the center. And scientists say its very hot there.
this means I will have to wait another 3 years to travel 25 years back and of corse go 28 years back to let the air out of someones tyres then go forward in time 24 years tell myself I have changed something and why I did it so that 4 years later I will still go back otherwise I would'nt know I had to go back and let the air out of her tyres in the first place then travel forward in time another 4 years to get back and hope I still done it.

Huh? What? Am I the only one not following the train of thought there? Observing the past is the closest we'll ever get to time travel into the past. (By outrunning light and then observing it as current light catches up) Time travel into the future might someday occur when we reach, near or break the light speed barrier, but the effect would be permanent... there would be no coming back to your own time. It's a one way trip, IF it's ever possible. Forward only... that much is already agreed upon by most of the scientific community, right? |

Born blind, I don't know about light, and I would not fully comprehend it if you explained it to me. Would it be possible for me to even know I was traveling at the speed of it? |

Wow, now THERE's a thought.
If time travel is simply moving faster or slower than the speed of light, would someone who cannot see the effects of light ever be able to time travel?
We're constantly viewing the future, and there IS no present.
Can you ever say you exist in the present? No. As soon as you say it, or breathe, or think, the present is gone. You can never live in the future, nor in the past, and the present does not exist.
So where are we?
Damn, I can't remember which philosopher's line of thinking that was...
I myself think that even if time travel is possible, there is absolutely no way that we could ever affect the past. (Affecting the future is not possible, because you can't affect something that has not yet been played out.)
How would we ever change the patterns of the light beams we see? And if we did, how would it change the physical world that created such light beams?
Don't know, don't care, 'cause I don't own a Delorean anyway 😊
And where would I get 1.21 GigaWatts?
Huh? Where? |

If all this is possible, I think I must have.........Mmmmm, Ice cream never got better than that until other things started to replace it. It always starts with ice cream and then the next thing ya know, you look in the rear view mirror of your Ford stationwagon and see five kids and a big dog, acting all wild in the back and at that point your reminded of that summer you and your then, future husband spent observing wildlife in the Grand Canyon.

Of course by then the definition of "hot" might have changed to "1000 arms and 300 heads," but I'm willing to take that chance. |

Well, part of all this argument rests upon the Theory Of Relativity. And one of the linchpins of THAT is the way you interpret the Mitchelson/Morely experiment, which could have been flawed in method and execution.
An Italian scientist has suggested trying the whole thing again, in the "New Scientist" of April 2. Yes, the date is suspect, but as people have suggetsed doing the test again, or at least firming the whole deal up, maybe it's not only genuine but a bloody good idea.
( Quick notes: The Mitchelson/Morley experiment was to test the existence of a fluid medium called aether, through which all EM waves propogate. If it existed and was fluid, the motion of Earth in orbit would leave a disturbed wake that would distort EM waves. The experiment showed no distortions. M and M 😊 concluded aether may not exist or it might not be affected by mass; Einstein concluded it didn'y exist at all, and other physicists thought that it might exist but only as another dimension - Lately resurrected as brane theory.) |

We are never gonna reach the speed of light. I think you can forget that.
You guys are so busy dreaming of how to go faster than light you are forgetting an easier solution.
I think you should throw in all your energy in slowing down the speed of light!

I heard a couple of years ago about a method developed for telekenisis by freezing atoms to slow them down. Then they were somehow transmitted by laser hologram to another location. In theory if this process were developed further, then larger objects could be frozen, electronically disassembled and then transmitted somewhere else. The next step would be figuring out how to transmit the information back in time or forwards in time. What we accept as everyday stuff now would appear as magic to someone from 500 years ago. here are still people alive who were born before TV, radar, space travel, so why is time travel so impossible ? |

Has Someone worked out how long it takes our sun to orbit around the centerpoint of our solar system and how many km we are from the center(please dont mess about I need the info in exact millimeters & seconds). I still don't trust the gravitation theory that a time mechanisme will go along with the earth threw time.

Tirrag,
This may be a little late... but the centerpoint of our solar system is the sun. Granted it's not the exact center of our solar system, but the centerpoint of the solar system is a point located inside the sun. Much like the moon doesn't orbit the Earth, the Earth - Moon system each orbit around a common point in space, but, just like the larger scale version (solar system) that point of orbit is located within the Earth. So the Suns orbital period around said point won't be that long...
Did you by chance mean how long does it take the Sun to orbit around the centerpoint of our galaxy? If so, that's a completely different question and even when you do find an answer it won't be given in millimeters and seconds I'm sure. |

I still have a feeling that if someone was to time travel a day back in time your gonna have to wait 24hours till the earth finally reaches you and it will come at you at 29.785 km /sec! If you were to go a day ahead of time you will have to travel faster than 107226km/hour to catch up to the earth. If you could reach a speed of 200000km/hour it will take you 27.7386337 hours to reach the earth. So you will have to travel at 215000km/hour to get there ahead of time even a bit faster knowing it will kost you some time to acelerate and slowdown that you dont crash into the earth.

Rex mate!didnt ya know!
Experts think time exists just like space does bro!, Time is the passing of a low entropy state to a high enropy state, or an ordered system into a more disorded system i.e our universe through time, or indeed our very selves! It is because time is 'real', and not merely perceptual, and inturn relative to other processes, processes that are maleable, that time travel is possible.Think of it as a ratio,
space/time of fixed value. if you lower space, you in turn must increase time. |

It is wonderful to read your discourse on time-travel. Can time be defined as a physical property or conceptual description? Empirically, we can observe the motion of light, but by doing so, are we observing time? If we say that light and time are of the same physical category, then time has, by extension, the same properties as light, which are duration, intensity, particles or wavelengths. If you say that time and light are the same, then by absorbtion, one of the two is negated, because one cannot be distinguished from the other, therefore if time exists, then light does not. |
