i wonder if aleins, greys etc, are us from the future. maybe earth in 1000s of years time humans and had the teckno to travel great distances to other galaxys and that something happened to earth which lead to earth been in total darkness or something like, we as a race evolved and ajusted to the condition on earth, and have a thin body to counteract great pressure in the atmosver and maybe y greys (us)have big eyes to let as much light in as possible because of earth darkness,ok so now we live on a new planet and have invented a time machine or something like, and we travel back to our time now, so maybe thats maybe why greys (us) come here to keep a watch on earth on trying to change wat is going to happen to our planet and put it right again, but they failed, because greys (us) are the product of wat is going to happen, if u know wat i mean, oh well off to bed got work in morning

lol, just a while ago i wanted to post the same idea but u are faster then me
I agree, maybe it is, and u think they still don't know that they can't change anything anywayz???
Anywayz it's just a theory among of hundreds others where we can't tell if it's true or not....

I once thought the samething

Nope...time travel is not possible, in the manner in which you speak.

I read in a book once that the Mayans may have achieved enlightment and decided to become star travlers with modified bodies from being in the spirtiual relm.

Physicly time travel is impossible because time is reletive. And in thousands of years time we will have destroyed ourselves most likely.

A while ago, i saw a program about Einstein. It said that Einsteins theory of relativity makes time relative to speed and makes travelling in future possible and even travelling in the past under very certain circumstances...

so Don't mystify if you dunno plz

There was a 1994 movie called: "Official Denial" staring Parker Stevenson that was based on this idea.

Quote:
The little grey aliens are future humans who genetically engineered themselves to survive a post-apocalyptic earth, and they are not only coming back for genetic samples to repopulate their world, but also to sometimes befriend people like Paul in hopes of changing the future for the better.

i know time travel is impossible, but traveling in to a different dimension is possible, you can travel to a dimension where time has not progressed that far, but every dimension has its diffrences maybe the problems in the future dimension dont happen, so why make a trip from a dead planet insted of going to a diffrerent one (interdimentional travel requires lots of energy) i dont think we will live on this planet for more than another 500 years super volcanos, astroids, and so on

Human, it can be speculated it depends on how you perceive it, but sound science says time travel is impossible because time does not exist.

dbz_ssj4, a different dimension merely means a different geometry instead of 3 coordinates like 3d, 4d would have four coordinates. Surviving the change would not be possible.

The theory of reletivity states that an object moving at a higher velocity would perceive that less time had elapsed than on a non-moving object. But that time is reletive tot he object so no time has been travled. Understand?

Ah heres some stuff out of wikipedia

Some theories, most notably special and general relativity, suggest that suitable geometries of spacetime, or certain types of motion in space, may allow time travel into the past and future if they themselves are possible. It has been confirmed that the effects of relativistic and gravitational time dilation can cause a traveller who starts at and returns to a point of origin that remains stationary, to arrive at a time farther in the future in that reference frame than their subjective elapsed time would indicate (a constrained form of time travel into the future).


http://en.wikipedia.org/wiki/Time_travel

If you can travel back or forward in time with diffrent dimensions (parallel universes), (note... 3D, and 4D is just simple highschool physics) means if you go into the past and change something and you come back, the change would not effect your own time/dimension becouse things and people cannot vannish, well you ask yourself what did i change, you changed that dimension

A dimension is in no way a parrallel universe, its a geometric word and here is the meaning (http://dictionary.reference.com/search?q=dimension)

" Mathematics.

1. The least number of independent coordinates required to specify uniquely the points in a space.
2. The range of such a coordinate.

Physics. A physical property, such as mass, length, time, or a combination thereof, regarded as a fundamental measure or as one of a set of fundamental measures of a physical quantity: Velocity has the dimensions of length divided by time. "

If time does not exist then how does change occur and what enfluences that change.

Is it true that we're getting smaller and growing a bigger head?
Friend told me this sounds really strange.

Time is a reference to instances, so time itself doesn't exist but the instances do.

If time doesn't exist then then space mustn't exist and everything would be nothing. Thankfully, you are wrong. And the universe can exist in despite of your constant ravings and proclamations to your vague descriptions to idealistic provential thoughts.
Time is the thread of space in which all levels of energy may exist and conform to its practicallity. If it is possible to send an energy to it previous practical version, then to cascade the energy sequence of practicallity in a mass ultraformity. then all is to stop it is the energy required to do that and what happens to that energy.... well, its just a conversion so it will turn to its previous state. And do you have any idea what instance means? "We don't need no education", well apparently you do so when you do that, you can send your appologies in the self realization that you have no idea as to what you are talking about.

its possible that 'aliens' could be humans from the future, i think so too.
but also that aliens from outer space, do also exist.

There have been many sightings not just flying saucers. The titanic for example, there was another ship visible and could have clearly seen the titantic sinking, and helped them, but the ship never moved, and dident send any replys to and signaling.
a ufo was spoted near the twin towers at the time of 9/11.
there have been strange objects in pictures from medievial times and times of jusus, and beyond.
some of the evidnce could point to important time that change the world, or was something great in history.
theres been unkwon craft detected on radar during the second world war aswell.
so, humans could be do time travel tours in the future, or just someone travelling time, also ufos have never attacked or made a change to us, wherever. the ideas of it are endless. but not all ufo sightings, but maybew humans in the future, think to make tiem travel ships like ufos so that people only think there ufos.

heeh.... don't like to talk about things i don't clearly know... And noone of you does know, so don't be specific if time exsits or doesn't, Don't you think the scientist don't have those kinds of ideas??? Of coarse they have... and more convincing and mysterious...

ThePredator you're too close minded to understand something that is beyond your grasp and way of thinking. This is the reason why we'll never get ahead, so long as people like you believe everything is impossible and everything must be as clear as black and white.

There's much out there that you don't know about, nor understand. And so much more you cannot even grasp your mind around, as of right now.

To flat out say something is impossible is just ignorant, and as long as we have people that think this way we'll never get ahead nor understand our world, what we really are, where we came from and what the universe really is...
