I was reading about how humans might look in the distant future and it described something that looks a lot like the usual image of an alien. I really dont remember where i was reading it, but even if humans dont really look like we think aliens look, im still talking about the whole idea of humans from teh future coming back in time. Big head, big eyes, no ears, little nose holes and no hair...etc. This might not be anywhere near how we are going to look in the future, We dont really know for SURE what were going to look like, just have VERY good guesses. Also we dont know what could happen to earths climate to change the way humans look. And i know some people say if time travel is real then we would see time travellers from the future. Well what if what we think are aliens are really us travelling back in time. And they just dont land and communicate with us because they dont want to mess with anything in the past that could screw up the future or theyre creating parallel universes. And abductions could be us from the future too. Maybe time travel in the future is used by a lot of people and not all use it the same way, for bad or good.

Edited it to explain myself better

If they are us from the future - the fact that we have 'seen' their craft has distorted the time line, and thus may end their existance in the future. If they are a futuristic 'us' then I'd hope at least they'd be more careful.

Where did the people who produced this projection of Human evolution get all their info from? Throughout history people have been getting taller...very old buildings in England have 4 foot doorways that suggests we were smaller. 'Greys' are always shorter than we are.

Also - why do we lose our hair, lips, and most of the nose? They haven't changed much since Homeosapien man evolved, suggesting nature got them 'just right' in the first place.

Finally, I doubt our eyes would turn out like that, for sharper vision, bigger isn't always better. It would be more likely that a small mutation in our retina, rods, cones or lens, for example, would produce better sight than simply big black eyes

Your premise doesn't make sense. First, the image you describe of alleged aliens was created by humans to sell books about aliens and alien abductions. But before that happened, Hollywood beat them to the punch.

And if aliens are us from the future and they don't want to communicate with us because they don't want to mess with the past, "they" are already doing so! So our present is being disturbed by future occupants, if you were right which I don't think you are. If you call your flawed thinking perfect sense...

First off, if many-worlds is correct, then visitors from the future could never visit their own past, just one that was pretty close. Messing with our present wouldn't create paradoxes because our time is not actually their own past.

If we're to believe people's stories of encounters with ETs, then they are bilateral, bipedal, with two eyes, a nose a mouth, hands, etc. They're basically 99%+ us anyway. If it's true, then they must have come from a planet where not only the environmental conditions, but also the history, are nearly identical to earth's. Can you imagine planet earth, except missing an extinction event or two, in which the trilobites beat out vertibrates as the supreme land-dwellers? There are fossils from the pre-cambrian which we aren't even sure belong to any of the kingdoms alive today. Think about that. If things were just a little bit different, we might have ended up sharing the world with creatures that were not animals, plants, fungus, or anything else we're familiar with. And we're supposed to believe that a man from another planet is knocking on the door, and that he looks exactly like us?

If we have been visited, which I very strongly doubt, it was almost certainly by our far-flung descendants from a similar time-line.

I'm honestly more quick to believe that "UFO"s are time travelers, more than I would believe they are actually beings from somewhere else in the universe. In fact, in Hunt for the Skin walkers one of the main conclusions they made was that the ranch was some sort of gateway between dimensions and that the things people were seeing were a rift or a thin place between these dimensions, not aliens. It just seems so much more probable to me. I DO believe that there is life in the universe besides us. If it happened here it has to have happened somewhere else. It doesn't mean it happened the same way but it has to be working somewhere else. Anyway, this is a fascinating idea that I don't think I ever really gave serious thought.

This is impossible because our future hasn't happened yet. Are you saying that right now, we're all living the past? Can you even wrap your mind around that? The future has already happened, which means that I'm already dead and my kids are probably dead and so on and that we're all stuck in some kind of past? Doesn't make sense with me. The theory of time travel is nice and all, but not possible. The future has not happened yet.

No one has any idea how time works, or what time actually is so neither you nor I can answer your questions. Native Americans, and other indigenous style cultures believe that time is cyclical, meaning we live in the past present and future all at once, that the present moment has all time in it. Wrap your brain around that.

You are right rezna ~ we DO NOT understand how time works.... and I agree. By what I have read and all that it points to ~ the present (NOW) has ALL time in it. past~present~future is our own reality construct ~ created so that we can move through life and can compartmentalize experiences and events in our lives ~ And there are a few individuals that 'know' how to navigate the Greater Reality (if you will)... such as the Native Americans (ie. shamans) for one ~ that have navigated other realities/time for eons.

I can answer my question...time doesn't really exist. It's something made up by humans to better obtain schedules and they created calendars to help keep track of their days and such. Proof in that is that there are many different ways people tell time and many different calendars that exist. The Hebrew day is determined different than our days are now. So time is really a man-invented thing. Americans are more scheduled driven than let's say an African tribesman who probably has no concept of time or even know what day of the week or month it is. Will time travel ever be possible? I don't think so, because what is time? Can you manipulate it? You can put into a futuristic computer Sept. 11th, 2001 to try and go back to stop the terrorist attack...what do those numbers mean? Nothing. That's the date we signify for that event, but without dates...it means nothing. We wouldn't know how many years ago something happened if it wasn't written on a calendar. Back in the day did people write that this happened at such and such BC?

Where did you read this stuff at, Johnny?

The only way you could time travel would be if you could also shield yourself from the changes you might make - and thats decending into the realms of star trek

I believe the OP is correct.

I believe also that it is impossible for a time traveler to create a paradox (mainly because people are thinking 1 dimensionally on the subject and forget the other perspectives in the time travel)

So, if they are time travelers I would also conclude that likely the travelers would be androids possibly linked to a consciousness back at its origin time.
Purpose? Since its impossible to create a paradox, likely its gathering information, perhaps figuring out where we went right or wrong?
Who knows how far science will alter our DNA?
Perhaps they may be collecting an analyzing DNA to get themselves back on track?

I don't think it's even possible for us to look like the greys in the future. Maybe they're highly trained robots made to look like aliens from our future ancestors. They send them back in time to abduct and to run studies on the humans so they can come back and give them reports. That way the future humans won't really alter history in a way because the present humans would think they were abducted by aliens, when in reality.. the greys are just robots made by future humans to deceive the present humans.. LOL I'm even laughing at my own scenario but you never know.

But them being here and interacting with us at all would affect the future. Not only that, but what are they doing with all the abductions? Just throwing that out there.

It has been said, this presence or influence, would be possible.
Within a Sci/Fi movie: "The Time Traveller".

Within this, many tried to call him and others tried to stop him when he appeared.
It's one of my favorite picture shows. Hard to deflect. Joke of operations.

Within the scope of the scripts, yes there are multiple resolutions, of interpretation; there's one that jumps to mind.

When the Time Shifter, noted of a past-call. Someone whom he Eternalized, and banished from existence was unsuspended. And had three new friends, within context shift.

Yes, he imprisoned 3 other lost souls. Quite fascinating....

Systems that measure time do not equal time.

Man has also discovered different ways to measure temperature, weight etc. It doesn't mean these are purely man made concepts just because man invented a way to measure them.

If time itself didn't exist. Nothing could happen. How can something move from one point to another if time doesn't exist. It would have to be both places at once.

You cant be serious.

What? He's right...Time isn't real. It's just a way to record a sequence of events.

Man, Einstein must have been a real dumb a*** then to base so much on something that isn't real (sarcasm).

Systems of measurement such as dates and hours, minutes etc. are NOT real. Time, however IS.

If a sequence of events even exists, then there must be a before and after otherwise it's not a sequence. How can you have a before and after if time isn't real? What separates the start of an event and the end of an event so that you can't see both at once? It's separated by a dimension called 'time'. Unless you define the word 'time' just merely means the hours etc. that we use to measure time. But then it leaves the other phenomenon that I would call "time" without a name.

Fahrenheit and Celsius are just random arbitrary systems made up by humans. I could make up a totally different scale to measure temperature if I wanted. And it'd work just as well. Doesn't mean temperature isn't "real" or that people made it up.

The Earth is said to be 4.54 billion years old. Did scientists make up this number totally randomly. Or was there a certain "something" that made it this old even before humans invented ways to measure time such as years? I tend to hink it's a certain something I like to call "time".

This is true, but it is a philosophy as much as a science. Yes we created a system in which to measure the passage of eerm time for want of a better word. But what is it actually that we are measuring? The orbit of earth around the sun, the rate at which cells degrade and die, the conversion of matter and energy, all things that have a bearing on our life.

This is not to say that other animals and maybe alien life may perceive the passage of time differently. Einstein predicted that the passage of time can be very different from one observer to another with reletivity. There is a hell of a lot more to it than the simple passage of time though, and only a few very gifted and talented people can really grasp it, unfortunately I am not one of them so I'm gonna leave it there hehe

I've actually thought about the possibility of extraterrestrials being a future version of humans. The only thing that doesn't match up is how they're traveling back in time. If they're using some sort of time machine, the farthest they can go back in time is to the point the machine was created. So, unless someone created a time machine years ago without anyone knowing then that's not a possibility. It's fun to think about, but I definitely think that they're from some other place in the universe. The universe is just too big for us to be the only ones in it. Too many planets, galaxies, and maybe even multiple universes.

Im sorry, but no, he's not right. Time is very real. You would not any of what you have now if time wasnt real. I dont know how people can say time isnt real!



No its not.

How about the point of reffrence,or if time isnt real why is man so addicted to the digitial watch?

Why would it be limited to the time just when the machine was being created. The current view of time going cycles rather then linear and time could be bent in wormholes, I think it make more sense to say you could land anywhere in the cycle. The universe being too big for aliens not to appear also works the other way cause they would have been here by now. I lean more towards them being us from the future or at the very least humanbots.

How do you know they haven't been here?

Watch this to get some better insight about the time machine. http://youtube.com/watch?v=mGrBNtJjsU0

"If I turned the device on today and I leave it on for a hundred years, then someone a hundred years from now could travel back 75 years, 50 years, 25 years all the way back to the moment I turned the device on but they can't travel earlier than that because the device didn't exist earlier than that and it's the device that's creating the effect."-Scientist Dr. Ronald Mallett

But what about the flux capacitor? Its still running in the Deleorean right?

My god, man thinks he is so alone he's beginning to believe aliens are himself from the future?!?

Its vastly more likely that the universe is teeming with life!!!!!!

EDIT: typo

Again, how to put it anymore clearer, where are they? If its teeming with extraterrestrial life theres no solid proof of contact ever. You dont really believe theyre playing hide n go seek do you. SETIs gone thru all the visible and obvious locations and came up zip. IF theyre far advance in technology, getting here wouldnt be a problem but nothing. Its really a romantic idea having other beings out there but its really looks like we're the only ones here before now and the future.

Time is a human construct. I think it would be fair to assume Einstein saw that in the same light. In fact many of his "thought experiments" http://plato.stanford.edu/entries/thought-experiment/
questioned the very nature of time as we experience it as humans . Einstien would be the first to tell you that time does not necessarily work they way we understand it currently. Our measure of something like the age of the Earth may be accurate for us given our understanding of time, but it is not a validation that our construct of time is true for anything other then measurements of our own reality.

If time was merely a human construct, wouldn't it behave exactly the way we understand it, by definition?

From what I remember, Einstein considered time as important as space, in our universe. Surely it couldn't be merely a human construct?

I mean, yeah, time is relative and not an absolute etc. But it doesn't mean it's not real.

If they were us from the future wouldnt that create one of those...things that destroys one or the other?The clone is always destroyed or something....

It's quite an interesting theory actually. I'm not sure that's really the case though. Through evolution, all creatures adapt to their environment. So imagine what needs to change to trigger such a huge change in human appearence if we were to lose our hair, nose and ears. Human appearence, besides height, hasn't really changed that much in over thousands of years, while our environment has changed dramatically. If even a change from ancient civiliations to modern soceity with cars and airplanes and thousands of years doesn't trigger a change, then what would?

I think the idea of UFO's being people from the future watching us or over us is quite an interesting theory that could possibly be true. But I don't think humans would change that much in appearence considering that we've looked this way for pretty much our whole existence ever since we came out of our caves.

By the way, is it just me or does this topic remind one of that one Southpark episode where people from the future come through a time portal and look exactly like you described. 'They took our jobs!' It's the first thing that came to mind when I read this topic. xD

Modern society with "cars and airplanes" has only been around for a hundred years. That's not many generations. Certainly nowhere near enough for us to evolve because of them.

Note the ever receding hairline eh...

^ Looks cool. Too bad we will never know if that's really the the future of humanity.



That's a very good point. I excuse for overlooking that. I guess it might be even more possible then I thought.

If aliens have time travel capability, why can't they be evolved Dinosaurs that are travelling into the future....our present?

How is time a human construct? Time is a very real part of the universe. If there were no time, there would be no movement, no aging, no nothing.

Yeah exactly. Time isn't a human construct at all. It's a natural occurrence we've once named 'time'. Our only creation is the way we keep track of time. We have created years, seasons, months, days, hours and seconds. And even that's not really a human construct. It's merely a system we've thought of to calculate and keep track of the occurence we call 'time'.

HAHA!!!! That's Hilarious. I guess we will be so super advanced that we will just float from place to place instead of walking. However, then we would be totally overweight.

To get back to the subject, you are all juggling this time issue back and forth because you don't realize what time is. Time is simply the order and pattern to which our solar system and the surrounding galaxies and stars move and revolve. Time moves because we are spinning as well as revolving around the sun at a certain pace. That is all that time is. God designed it that way so that life could be the way it is today. Ordered. Evolution doesn't create order. God does. Time is nothing that you can't look up at the stars and witness it unfold for yourself.

What? No it isnt. Time is time regardless of whether the solar system or any stars and galaxies exist at all.

"Time" itself is a word used to describe the actuality of the natural order of existence. It does not stop, and it does not stop for you.

This would be weird, but Asteroth, "Through evolution, all creatures adapt to their environment. So imagine what needs to change to trigger such a huge change in human appearence if we were to lose our hair, nose and ears. Human appearence, besides height, hasn't really changed that much in over thousands of years, while our environment has changed dramatically. If even a change from ancient civiliations to modern soceity with cars and airplanes and thousands of years doesn't trigger a change, then what would? "

Well, analyze the technological advances within the past century. Our planet itself is deteriorating slowly, every second, as all things do. We already achieved space travel, imagine another hundred years, another thousand years - that is if we did not commit vivicide. At this rate, technology will advance drastically within the next couple of centuries, and we should be able to colonize other planets. If the environment is somewhat like earth and habitable, and yet different, we could evolve slowly over time and adapt to the planet, explaining the physical change.

Once humans can manage deep space travel, time travel would be inevitably the next thing. I believe that we, ourselves, are dropping by to check up on ourselves...that, or we are rats in an experiment...

Time wouldn't exist if the laws of nature weren't in place to tell it. Since the natural occurences around us are repetitive (which in itself is a commonly overlooked everyday miracle in itself) and for the most part can be expected to act the same way sunrise and sunset we are able to keep track of "days", "weeks" and "months".
If you were thrown out in space in an area where no stars or light were visible, patterns around you didn't exist then you would have no concept of time. Actually you probably wouldn't exist anyway due to the lack of light and everything that makes life possible for that matter.
In conclusion without light there is no life. .Gives new meaning to,.."Then God said, let there be light."

What do you mean? What "laws of nature" are necessary for time to exist?



Yes you would. You would know "hey, I've *just* been put here", and then "Hey, I've been here for a *while*"

The mere fact that you're thinking shows that there is time.

I think you are answering your own question there. Thinking is perceiving what's around you. But what if there were no factors around you in which to indicate to you exactly how much time has gone by? (ie sunrises and sunsets/ calendars etc.) Better yet, what would you say the time is? Once many repetative moments of thinking about those moments occurs eventually time won't mean anything to you. Time will not exist to you. For there is nothing to indicate time to you. That's when you will just perceive eternity if you are living forever.

Then you would have no way of measuring it, but time would still exist.



It doesnt matter if it means anything to you or not, it still exists.

What your arguing is like arguing "if you dont have a ruler, length doesnt exist."

I thought of this myself a while back. They are us adapted to space and time travel. When you think about the things they do like extracting DNA from people. Making sure we don't get any souvenirs from the crafts and they way they appear and disappear in a flash. Also a creature from another planet most likely not look anything like us, yet they have two eyes, bipedal, and hand with fingers. I think they are coming back to for DNA in the same way we looked for the first corn plant for it's DNA to use in making better corn.

I agree, the more I look at it the more I feel they must be human or droids sent by humans from the future or a parallel universe.

I like this theroy. Very creative. and maybe very true. Think about it? green house effect? maybe another ice age? man s appearence could can to adapt to the new world? could it be we are coming from the future to keep us from destroying oursleves? hmmmm interesting.

I'd have to say no. Time travel doesn't possible to me. Time is really just a concept of man if you think about it.

*sigh* No no no, let the people who know what they're talking about do the talking, k?
