Theory: UFOs are from our future where Time Travel is possible...?

Could that be the reason UFOs don't land & say "Hi", for fear of changing the past, and causing thier existence to never have been?

Serious & not so serious answers / counter theories welcome...

Have you ever watched "lost" they have an interesting theory for time traveling.

if they show themselves at all, didnt that change the past enough that they shouldnt exist?

Theories...Theories..Theories. theories which are only fruits of the mind that has no end.

Time travel is possible. We all do it every day.

If you mean travel back in time or to the future then no. It's impossible.

Unless you have a flux capacitor and a Delorean.

The definition of UFO is Unidentified Flying Object . Since they ave yet to be identified there is no theory about them that could possibly make sense except that SOMETHING is flying around but who or what is unknown. Most of them are PROBABLY military panes being tested whose existence cannot be revealed for reasons of national security.

There are a number of people who claim that we are being visited by our relatives from a distant place. These relatives look much like the EBEs described as "grays." They are suffering from horrible genetic deterioration according to Dan Burisch, a biologist, who worked with them to try to treat their skin and respiratory problems.

I have to believe that time travel is possible due to the fact that some many physicists are working on making it possible. I don't think that our ancestors drop in and say, "Hi" because of the reception that John Titor, a reputed time traveler from 2036, received. Although he had some concerns about altering our time line (which differed slightly from his), in general John said that changing the past was not a huge concern for time travelers because they came in on time lines that were not exactly the same as the timeline that they lived on.

There are many groups around the world working at a furious pace to create viable time travel machines. In 1999, a man who posted at a newsgroup for those interested in time travel. This man, named John Titor, claimed to be travelling from the future (2036). Many of the things that he predicted and/or explained have come to pass already. However, he also repeatedly stated that he did not come from "our timeline." In the past, scientists were concerned that time travellers might create "time paradoxes" such as killing themselves by accident in their own past. Titor unequivocably stated that it is impossible to travel to one's own timeline. The reason is simple. Who we are today is not the same person that we were in our own past. Not only is our body a different, size, shape and age, but not having been exposed (in our past) to the things that change us at a cellular level in the future, we aren't actually the same person. Adult me or Adult you is actually genetically different than our predecessor in the past.

Apparently, time is nothing like the way that we imagine it to be. Time exists as a past/present/future and deviations from the current path all at once. Every time location is contained in a multi-dimensional construct much like a cube of solid matter. SO, just as you today can remember yesterday, today and imagine tomorrow, the universe itself contains vast arrays of time lines with all possible outcomes coexisting.

According to Titor, it is possible to go backwards on a timeline that is not exactly the present one, but it is close enough that a time traveller can find his/her relatives and work with them to solve problems.

In any event, from everything that I have read of the research into time, Titor's information appears accurate.
