It still doesn't work, because any time travel that will occur int he future has already happened, so things will be the same as the present.
IE: You will never go back in time to kill your grandfather because if you did, you had already done it back when he was alive. Remember, if you are going back in time, you already did it and the results are "your present".
If you are not a decedent, than he is not a relative, and was not your grandfather....and you have simply murdered some stranger in another dimension....but, again, if you were going to go back an murder the poor guy, he died back then already...so, it already happened....and hes not there, now, to go back in time to kill.
I do not pretend to understand physics related to possible time travel, but I have read thousands of Science Fiction novels and tens of thousands of short stories.
There are three main views of time travel into the past in these stories.
1. It is impossible, due to the universe protecting itself against paradox or due to unbreakable laws of physics (not a very common view). Time travelling into the FUTURE avoids these paradoxes, so is sometimes allowed even when travel into the past is impossible.
2. By traveling into the past, if you do something, it has already been done, so you are fulfilling history (this agrees with TEEJ). An example would be someone trying to find out who had disturbed Beethoven and prevented him from finishing the Unfinished Symphony. He goes back in time, waits outside Beethoven's room to see who was the culprit. No-one shows up, so he asks Beethoven what had disturbed him, and becomes the person he was looking for, since he disturbs Beethoven. He had to go back in time or the symphony would have been finished.
3. By traveling into the past and performing an act such as killing your grandfather before he has any kids, you change the future universe so that you cease to exist, all descendants of your grandfather cease to exist, etc. snowballing the effect on history as time progresses. This tends to be a major issue when people go back and kill Hitler when he was a boy, or do something else with an even greater effect on history, such as to provide Archimedes with a current 21-st century knowledge of science, etc. In many of these stories, an organization of "time police" protects the timeline, protecting their own existence at the same time. Time police from alternate timelines sometimes battle to ensure that their own version of the future "happens." That can all get rather messy, as in the following paradox.
Paradox - If you killed your grandfather, and ceased to exist, how could you have gone back in time to perform this nasty deed?
Alternatively, making a change in the past spawns an entirely separate parallel universe, so the old one continues to exist, as well as the new one. There would be an incredibly large number of parallel universes based on this viewpoint.
This is all Science Fiction until we have more concrete scientific results, but it can be VERY entertaining if done well.
Of course, if time travel into the past is ever possible, time travelers from the future are probably among us, being amused by our antics, and probably trying very hard to not change history.

If we accept that time is filled with multiple universes in which the outcome of every choice made creates a new universe, then we can travel back in time. We can change something, and thus when we travel back to the future; that universe will have become the one that takes "Center Stage" for lack of a better term. In that way, we travel to that universe instead. Thus Time protects itself from paradoxes by putting different outcomes into different universes.
Change something in the past.... doesn't mean it was changed already in the NOW, which is the future when you're in the past. You can change the past. Just simply means that you don't get to travel back to your pre-existing timeline or universe when you decide to check out the future to see the results of the change. That universe is still there. Just means you don't get to access it.
Who knows.... Maybe our universe is just the one we exist in. Perhaps to us it's the one that's "Center Stage." Might not be the case at all. Perhaps someone already traveled back in time, changed things, and now our's is Center Stage. Perhaps it was never meant to be.
Perhaps someone traveled back in time already and saved a young German girl from getting run over by a car. Then as she got older, she saved a suicidal man from killing himself in front of her as the police came to arrest him. That young man was named Adolph. BTW, that actually happened. A young woman convinced him not to pull the trigger of the gun he held to his head. This was before he came to power.
In another timeline, a certain driver didn't make a wrong turn and give a different young man a new opportunity to carry out an assassination after a fellow conspirator failed.... Causing the young man to initially give up, and thus go out to get himself a sandwich from a certain shop located on a certain street that a confused driver decided to turn down on.... Thus causing a young failed artist/painter to have a different view of the world and a different view of certain groups.
Our universe might honestly be the wrong damn one.

Time is not always, but mostly, linear within the constructs of which humankind has imposed upon it. Like most constructs, it's made-up by the mind of man as a result of man's attempts to achieve order and control over his environment. In truth, all constructs of time (past, present, and future) occur simultaneously--and continue to occur simultaneously--at once, and in the moment of now.
Since the laws of bringing the etheric body in travel don't necessarily apply to that of the physical, the etheric body can more readily travel beyond the human constructs of time and space more efficiently than that of the physical body. This isn't to say that the human form is incapable, but has more to do with the mind. You see, the limits of what the mind is ready, willing, and able to accept--for most current human forms of existence--have yet to be achieved in the construct of Today. But regardless of whether the human mind is ready, such concepts of time and space are continuously bending, shaping, and expanding all around and within us. When considering both time and space as figments of the imagination rather than physical objects, we more easily free the mind toward the concepts of string theory, quantum physics, and other forms of supposedly "altered" states of "reality," at least from the rigid constructs that the vast majority of human consciousness has come to accept here on earth.
That's the background, now cut to the chase: Are people capable of travel in and out of time and space? They already do, constantly and continuously. They (mostly) just aren't aware. It's why the concept even exists in the first place. The issue isn't whether one can travel, but about how one may become aware of it, both individually and on a mass scale.

According to Relativity, time travel into the future is possible if one travels at a significant percentage of the speed of light, but it would be a one way trip. From what I've seen and read, most physicists don't think that time travel into the past is plausible. I wonder though:
If right "now" someone on a planet in a star system say about a 100 or so lightyears from earth were to build an unimaginably powerful optical telescope and trained it on our planet, they could observe the Wright Brother's first powered flight or the Titanic sinking, etc. In effect our past would be their present. I realize that they would be viewing an image, but it would be a real image. Perhaps the past, present and future all coexist simultaneously in different dimensions and the key is to link them somehow in a controlled way. Even if that's so, I'm sure that's not something that we'll be able to achieve for a long, long time - if at all.

Glad to see you agree with me :thumbsup:.
On this issue, I read yesterday about a recent interview given by Stephen Hawking. In it he said he believes there are parallel universes.
So hardly an extreme or out-of-the-mainstream view.
"The best evidence we have that time travel is not possible, and never will be, is that we have not been invaded by hordes of tourists from the future."

40 years in this universe has convinced me that there is no way that ours' is the one that belongs or is supposed to be center-stage. This world is B.S. (Ironically, also not an extreme or non-mainstream view.)
Honestly, who the Hell would want to visit a truly screwed up time such as the turn of the 21st century??
People from a more screwed up time. Who knows, these just might seem like the good old days to people of the future.
It's all relative, isn't it?

Respectfully disagree; it only proves that this time period isn't interesting enough over the others to visit. Sort of like if you had the ability to teleport to any location, you wouldn't go to a Wal-Mart or DMV.

Yep.
Time travel is irrelevant. The universe is a hologram, and the holodeck owners can set it to whatever time they like.

This thread needs more pictures :naughty:
For some, our current time is Paradise. Then again, who gives a crap what some mentally diseased lunatic thinks. (And there are a lot of them out there. Especially in NYC.)
There is an infinite amount of past, present, and future.
It is always the present, and always will be.
Anything you do is in your present.
The past doesn't exist as a looped play to go back and watch.
The future has not happened yet, and, there's no one there yet to go see.
Parallel universes are a mathematical construct, not a vacation destination. The same with dimensions. You can't "visit" another dimension any more than you could "visit" length or volume.
If dimensions exist (Length, width, etc...) we already exist within them....even if we are unaware of them.
It is not time travel to see the light coming from a distant star or planet any more than its time travel to watch a WWII documentary.
From what I can tell, if you reduce space to zero point energy (Empty and no energy), there are still random virtual photons that pop in and out of existence. Its just seems to be how it works.
If you have photons popping into existence, you have pressure-like forces that will be exerted by the differences in the wavelengths on either side of them, so some will be pushed to, or, away, from others...and, then we have matter and/or energy.
After that, its a free for all. ("Let there be light" - the the rest just follows....)
