Time travel is fantasy

[DCrist721]

I don't know about traveling through time as a person. But soon messages will be able to be sent to us from the future If I recall correctly. Some guy is in the process of constructing a machine that uses cintrifigul acceleration as a means to exceed the speed of light with messages sent in the form of particles. There was a thread about it here a few weeks/months ago.

that sounds very similar to the transmition of data through a coiled beam of light, the existence of which showed that light undeniably, is not a fixed speed... kinda putting einstein on shakier ground.


in a book i have called the ten dimensional maze (mainly a story book with old vector graphics illustrations) it is amusingly suggested that string theory is a 21st century theory that was put in the 20th century as a joke or accident. reminiscent of that guy who claimed to have come from the future a few years back? what was his name? tippur? or am i thinkin of john tippur now.. oh dear, what a muddle. anyone remember the name of the guy who got a bit of media coverage for his claims of having traveled back to tell us stuff?

The scientific "theory" of time travel is a science fantasy born of linguistic semantical error.

I never said people could travel back in time, in fact I specifically mentioned that large objects like people cannot travel back in time. Only particles such as electrons, positrons, etc. that strictly follow the laws of quantum mechanics. Even these particles are constrained by the uncertainty principle to travel back in time only a very small amount (on the order of the Planck scale).

What law are you going off of that states time can only go forward in all cases? Heisenberg's uncertainty principle is the staple law of quantum mechanics that allows for backwards time.

The theory a human traveling back in time is currently no more than science fiction.

All you need is a flux capacitor.

Seriously, time travel is not entirely fiction. One way to time travel is with a wormhole. You may think a wormhole is just as fictional as Star Treck but the concept of a wormhole is entirely possible. If a black hole and a white hole connect, an object that gets sucked into the blackhole will be spit out of the white hole in an entirely different part of the universe. While if this ever happens, he object will probably be ripped apart as soon as it crosses the event horizon of the black hole, the particles would still get through so the concept is totally possible.

Another way of time travel, while it isnt really travel is something you are experiencing every second. When you look at something, you are really looking into the past. When you look at the sun, what you are seeing is the sun 8 minutes ago. When you look at the sky at night, the farthest visible star you are seeing is really that star about 4,000 years ago.

I often thought about time travel when I was a kid I always wanted to erase the mistakes that I made; or redo an event in time so that I would come out looking better in front of people.

If you think of time travel in this way then you are correct to say that it is impossible.

However, if you realize that the material world is a manifestation of eternal energy, then you have to realize that this eternal energy has specific laws; just like electricity; and to understand these laws is to understand how to create matter from energy.

If there were no laws that prevented people from doing whatever they wished with this powerful force, then the universe and everything in it would have been destroyed in an accident a long time ago.

But, this energy is not subject to us, we are subject to it; but if we understand it's laws then we can become one with it.

At that point it is no longer a question of 'time traveling' because when you become one with the eternal time doesn't really mean very much anymore.

We will never travel in time.

I didnt read anything past that. Who are you to say exactly what humans will be able to accomplish long after we are gone? On top of that, its a pretty bold (some may say foolish) statement to make considering the technological strides we've made in only 100 years.

Imagine what we'll know and be able to do after 500, or 1000, even 5000 (if we dont kill eachother first).

I've said this once and I'll say it again, if a Universe is possible....anything is possible.

Very Nice


Time Traveling, most likely already exists, or some early form of it. The government doesn't want the inforamation to go out, so they hide it.

If we do, or have already done, break the speed of light barrier and be able to go faster then the speed of light, we can time travel forward.

This technology is very possible. Also, very likely to show up in the near future

Definitely not impossible.

How can you measure something that you cant see,know is real,or feel,or has any physical form ?

so the idea that is just a measure. what if the measure is innaccurate ?

and who came up that time needs to be in incruments of 60 ?



how do you measure something you created ? that isnt real ?

Barring everything in this thread but the first paragraph...

I just got done time traveling. Just visited a time from my past...so doesn't that count!? Of course it does! Over...

time has just been successfully manipulated, muahaha

Eh, don't take this too seriously, he's blowing it out of his fanny a bit. Here is a link to better understand the concept of white and black holes.

I think before anyone starts a thread like this they should post their highest level of education, just so I can stop reading right after it says " i'm not in college but i read some books" or "i saw a youtube video on it" or "I'm an astro-physics major (but im in my freshman year)"

and also this guy would have to disagree with you OP,

His name is Ron Mallet and I have actually talked to him, although I don't really think he is going to accomplish what he is trying to (travel through time), he is a pretty smart guy and has some radical ideas.. I know my other professors weren't too fond of him.

Who has EVER visited YOU from the future? TIme Travel is just a Scientific dillusion of modern gullable minds - nothing more. where is common sense in this board?

Imagine what we'll know and be able to do after 500, or 1000, even 5000 (if we dont kill eachother first)..

Its not about what we'll know, nobody said anything about that. I believe in Scientific advances to the future too , but i just can entertain stupidity in modern science.

I've said this once and I'll say it again, if a Universe is possible....anything is possible.

So wtf does this have to do with anything?

I just cannot believe the stupidity i'm reading here.

Lets Suppose time travel is possible. Then if is, wouldn't someone from the future have visited the past already? even in our lifetime or before?

We'd certainly know by now, but we dont. full stop

considering that time is infinite and at least one of the many people that will come about in the future would want to come back to our time. Yet no one has come to visit us. I think thats a pretty good indicator that time travel is impossible and further evidence that time does not exist as we think it does.

So i agree, it is just a stupid little fantasy which has been complicated by science and gullable scientific minds who belive every science journal they read.

quote: " everything we've ever been taught in modern science, is pretty much bullshit" dont where but i read this quote somewhere.

It is somewhat well-known that the theory of relativity predicts the possibility of certain change-related phenomena that popular science informally calls 'forward time travel'. The purpose of this post is to interpret in what sense these phenomena can or cannot be called forward time travel, after which you can determine for yourself how this interpretation squares with your original post.

</TD></TR><TR><TD class=quote>The science fiction fantasy of "time travel" is based solely on a linguistic "error", an amusing twist of grammatical misapplication, as I pointed out in the opening post of this thread.

</TD></TR></TBODY></TABLE>

Perhaps it is too metaphorical or 'linguistically erroneous' to call it such, but forward time travel can and does happen in the following sense. The theory of general relativity predicts that objects undergoing acceleration (that is, changing their velocity) will experience time more "slowly" than objects at rest (not changing their velocity). To translate that into something experimentally verifiable, general relativity predicts that accelerating clocks will tick less than clocks at rest. That is, if you had two synchronized clocks and threw one of them really hard, then picked that "accelerated clock" up and brought it back to your "rest clock", then compared their readings, you would find that the accelerated clock had an earlier reading than the rest clock. Scientists using planes equipped with atomic clocks have demonstrated that this prediction does hold in the real world.

The mind-bending implication of this arises from the fact that everything is a clock. All matter is undergoing change at some rate compared to other matter; when we compare the rates of change and give them a sort of "common currency" through which we express each rate, we conceive the idea of time. So while time is a concept subsisting in the human mind as you said, it corresponds to something "out there" which can be affected by acceleration, according to the principles of general relativity.

Now the observations of changes necessary to making a concept of time are made by each individual person; hence, while the abstract concept of time is common to all, it is "instantiated" separately in each individual. Each individual has their own common currency that expresses the relation between changing events as they perceive them. So what happens when an individual observer (such as a clock or a human) is accelerated? His currency is deflated! If he accelerates fast enough, processes of change that he would have called "5-second-events" at rest now become "1-second-events" to him. This is because the very processes of change within him have slowed down compared to the nonaccelerated processes (and this can be made precise using the clock-comparing experiment I outlined before). This devaluation of currency is sometimes called 'forward time travel' in popular science literature, but the scientific theories themselves have no use for the term.

So we may identify forward time travel with a sort of devaluation of one's personal time currency. The devaluation itself is a purely human-mind phenomenon, but at the same time it represents a physical reality, a fact about the relationship between rates of change. If I accelerate and my currency is devalued, and then I stop accelerating so it is revalued, the world doesn't care about my currency. That's just in my head. But the world does care about this fact: I truly am physically less aged than if I had never accelerated at all.

Thus forward time travel is a sort of 'fantasy', subsisting only in and through the mind's concept of time, yet it can 'happen' in the following sense: the experience of apparent time travel is possible, and the experience corresponds to a physical fact, one which we might call "relatively slower aging" or some such.

What is your opinion of time travel now, given this background?

Absolutely irrelevant.

It isn't a question of how fast some faster moving clock ticks somewhere.

It's a question of whether one in body can "return" to the year 1950 or "leap ahead" to the year 2050 as referenced by a date-and-time marking standard clock ticking here on Earth at the rate a clock usually ticks here on Earth during all those years.

The standard to determining true time travel a la Star Trek science fantasy fiction is whether you have traveled some "when" relative to that standard.

In this topical case, that standard is that date-and-time marking standard clock ticking here on Earth at the rate a clock usually ticks here on Earth.

You can't accelerate some clock somewhere and then say time travel occurred for all on board with that clock.

Time travel as we speak of it here in this thread only occurs relative to a standard constant, that date-and-time keeping clock sitting on our planet and traveling at the speed our planet travels, as that is the only accurate measure of timestamping in the matter.
