You don't understand how time works.
It occurs to me, if I ever did make a perfect time machine, I'd go into the past and give it to myself. Thus eliminating the need for me to invent it in the first place. I guess we'll just wait and see...

There is no absolute notion of the rate at which time passes. It depends on your reference frame.

Oh I see what you mean..
That's funny as hell! We couldn't possibly tell the rate at which time passes, but yet it is passing all the time, even second by second if you want to see it that way. Or hour by hour, or billion years by billion years.
So.. what I can tell is that time moves slow, or that there is just simply so much time we could rebuild our civilization like ten times over and over again. Mind-boggling.

The good ol' bootstrap paradox.
I say it is not possible but you are able to travel to alternate dimension where it is a replica of what it was like in the past of your current dimension.

Right, but there is still a relative notion. You can measure how much time elapses between two frames of reference.
It's such a stupid concept. Time is an intangible manmade form of measurement. You have a better chance building a machine that teleports you to Valhalla.

time is a measurement, like distance you can move along it either way. saying time is a man made thing is like saying distance is man made. the unit of measure is but not the measure itself
and saying its stupid is blatantly ignoring the FACT that travelling in time (forwards at least) is possible
Don't fuck with the fabric of the universe, it would be quite unlikely that we would be able to time travel , let alone use some kind of teleportation device with any [U]success[/U].

Well, we once said it was impossible to fly, and we ended up on the moon.
But time travel has a few faces. Such as physically going from point C to point A or vise versa. OR that sci-fi Time Manipulation centered plot device that makes FTL possible.
Soooo honestly, given enough time I'm positive some sort of time travel be it "Skip-go" into the future or a ride back into the past. The thing i really wonder is why?
If we could "Look" into the past without actually physically being there wouldn't that be enough? Going back in time has the potential to do extreme damage. Putting all the paradox's and ripping the fabric of reality aside for a moment.
If a person could go back in time and try to prevent a mistake. Then that person would never take responsibility for his or her actions, and basically never learn from mistakes. And i wouldn't want to even start to begin now bad things could get if people fell into this mindset.
Now if we created some sort of time-machine that would allow us to fly around space safely and at stupidly-ridiculous speeds, which i have my doubts is even possible... then cant see it being to bad.
I've watched many shows on this, and they've all convinced me its possible. We cannot travel back, but we can travel forwards. See, according to what some scientists say; you cannot travel back past the date the Time Machine was created because it did not exist. There are many theoretical ways to travel in time though. Just going into space is one. Another is going around a black hole, worm holes is another. Then there's traveling at the speed of light. Main problem with those is theres no turning back, but I guess its a down-side one could get over with flying cars on Mars.

If we were able to travel back in time, the paradox would only affect the user.
Example: Guy A and Guy B are friends, Guy A goes back in time and kills Hitler himself, Guy A disrupts his timeline and changes it for him. However, Guy B did not go with him, Guy B will live in his own time without Guy A.
Time travel is a strange concept, what if Guy A comes back, does Guy B in his timeline meet him, or is Guy B never gonna see Guy A in his timeline again?
I thought it was fairly common knowledge that a sense of accelerated "time travel" is possible through relativistic effects.

When we have the ability to do so is obviously a completely different story. I'm happy to believe travelling to the "past" is a bit of a null concept though, I think there's a good reason it brings up so many paradoxes - we're trying to translate [I]our[/I] interpretation of time onto the physical world - it's the limiting nature of our consciousness that leads us to think of existence in terms of past, present and future and trying to apply these limited ideas outside of our own minds will unsurprisingly cause mind fucks. /opinion
I think it's po the possible, but if we travel into the future, we woun't see ourselves as we would have been missing for (insert whatever time you inputted here)
And if we someone chainged history, we wouln't notice because it already happened.

So, because distance is a measurement, I am incapable of moving backward[/QUOTE]
Distance exists. Time doesn't. Time is just change of everything. I'm not good at explaining things but I think it is pretty dumb to believe tt is possible. Not even with ftl but that's my opinion. I've read about it and I don't see how light illusion = tt
[QUOTE=Reader;34791350]Distance exists. Time doesn't. Time is just change of everything. [/QUOTE]
How do you claim that distance exists and time doesn't? Time exists just as well as distance does and in fact in relativity, units of time are taken chosen so that they can be measured the same as distance in space can. (Using light-seconds instead of seconds, for instance, the distance a light beam travels in a second, allows you to convert a duration into meters) Space and time are just dimensions of a single four-dimensional manifold, spacetime. A duration is just the spacelike length of a path through spacetime. A clock is just a ruler for a time-length.
Time cannot just be explained as "change of everything" because clocks in the same reference frame can be synchronized and then shown to measure different elapsed times depending on their paths through spacetime.

I'm going to have to go out on a limb and say your opinion is not really sufficient basis to claim time travel isn't possible if you don't have any more formal basis for the claim. Science has already pretty well shown that under our current understand of physics, it's perfectly allowable.
And what "light illusion" are you talking about? None of the effects of relativity are some sort of illusion. They're consequences of the geometry of spacetime.
Well, I'm kinda dumb
Time travel to the future is certainly possible and has been done, just on a very small scale. By small scale I don't mean minutes or seconds, I mean a few billionths of a second. It has still been done however.
If Einstein's General Relativity theory is correct then time travel to the past is also possible but it has never been done and the problem of paradoxes arises. Some scientists think there could be parallel universes but there is not a single shred of evidence to support their existence so far.
The thing with traveling forward is that it's less of instantly appearing further ahead but rather time passes slower for you. You would experience less time than everyone else so when you got out of your time machine it might have been a year for you and five years for everyone else.
[i][b]woah hey huge fuckin wall of text here[/b][/i]
A few ideas on time travel here.
No doubt you've considered the idea that if you were to travel anywhere through time, forward or backward, your machine would need to traverse space as well, so that you could arrive on Earth again. Knowing that if you didn't account for such, your machine would transport you to the exact spot in the universe you were at, but at a different time. The universe's spin would mean you would most likely end up in space way behind in the orbital of the solar system.
So, your machine would need to have a universal coordinate system. One with an absolute zero, around which everything orbited. I like to think that if this measurement system existed, then we could pinpoint the center of the universe. And from that, find out how large exactly the universe is/if the universe is fixed or is expanding.
I've thought that if I were to write a medium of scifi including time travel, then it would take the Ender's Game series' approach. Something would pull the matter out into an extradimensional space, with variable/undefinable physical laws. To travel through time, a system would be in place that was created when the first time machine was activated. At first activation, the device created a signal, like a grappling point, in this pocket, and future voyages would attach to this point to send things to it, creating a thread through this extradimensional space. The signal would lead the objects back through to the location of the machine in time and space, so one wouldn't have to compensate for the things I wrote about above.
"Grappling points" would need to be created manually, making custom destinations impossible. This also helps the plot, because virtually everything that happens in a story about time travel can be fixed by going far back enough.
The machine would also account for the matter you would be replacing when you arrived in your destination. Much like Terminator 2 depicts the sphere of earth and oxygen that was vaporized by the T-101's arrival, this machine would rather define an area of matter to be transported than try to define all the atoms which make up its target. The machine in the future/past would exchange the matter in its holding bay for the matter in the recipient machine's bay. To make absolutely positive nobody loses the bottom portion of their foot, the bay would be a weightless environment so you could position yourself in the center with plenty of feet of buffer zone inbetween you and the edge of the defined target area. Because what if the machine's metal warps slightly way far in the future, and the sole of your shoe gets stuck in the floor of the device?
I dunno, I've pretty much took all the problems I've thought about when observing scifi's popular time machines and tried to fix them. Mainly I was just looking for some criticism and discussion. Thoughts? I guess I'd rather think about the engineering problems then focus on the theoretical, scientific obstacles. No explanation for how we could enter this extradimensional pocket, or even power such a device. :v:
Its possible perhaps to transport the ego through time through physical scientific means. But in reality time is more an illusory construct of the way we perceive reality with our ego consciousness.
If time travelled was possible through spacetime... err, wouldn't everything have to happen backwards? For example explosions would have to implode and particles that have disappeared (if that's possible) would have to appear again, and every chemical reaction would have to be physically reverted?
