You wouldn't perceive anything out of the ordinary on your timekeeping devices.
The massive discrepancy wouldn't be apparent until you returned to your point of origin.
Theres lots of good hard SF that plays with this. 'Tau Zero' by Poul Anderson, while old, is considered a classic.

Good hard science fiction. That is all this is. All the links that were posted confirm this. Someone traveling at the speed of light for any amount of time will have had the same amount of time pass as the person still on earth as in measured in ouir units of time. The perception of how that time passes is the only thing that is different and it can be hugely different. Light nor speed determines time.
Time dilation was not only proven, but proven repeatedly during the Apollo program with two atomic clocks, one aboard the space capsule, and one back on Earth. As the craft proceeded to go from Earth to the Moon and back at 20,000mph+ (depending on what part of the mission they were at) the time dilation between the two clocks was then thoroughly recognized and documented when they came back home and the two clocks could be compared, which irrefutably demonstrated that although it was a very small difference given how far from the speed of light they were, the acceleration closer to the speed of light relative to Earth did indeed reduce the rate at which time passed for the traveling clock relative to the one on Earth.
Maybe not all aliens,but i'll bet that some of them that are appearing here amongst us,are showing up after traveling out into space in their flying saucers and their flying saucers wether by accident or design,are time machines...

Time dilation? UFO reports quite consistently describe their movements as erratic, flitting from point to point at what adds up to low net speed, yet also jumping miles instantaneously, which obviously has nothing to do with avionics or rocketry. Whether such visitors are ETs using mastery of the zero-point field, interdimensional "ghosts," or time travelers, their method of getting around, developed paying Einstein no heed, is not subject to time dilation.
And if they are from one or more exoplanets, such planets are likely no more than 54 light-years away, since there are plenty of sunlike stars older than ours within that radius. Astronomers used to say 46 within 54 light-years, but the most recent Wikipedia article on it lists 49 within 50.1 light-years.
It's not impossible that humans made it to the stars long ago, using what we think of as ET tech, and that the stay-at-homes got knocked back to the Stone Age 20,000 years ago by an asteroid strike or antimatter war. But that has nothing to do with time dilation.

I've got to say, interesting theory. But wouldn't these advanced civilizations know about time dilation? Surely they would have tested their technology out and ran into these problems.
Also, I once heard a physicist say something that I believe hits the nail on the head when it comes to aliens;
"if you was one day walking through the woods and you came across an ant nest, you'd probably watch it and get a little closer for a few minutes, but then you'd carry on your journey.
You wouldn't bother trying to communicate with them because your far more advanced and intelligent than they are.
Well this is probably how aliens perceive us!"

Not to dis Einstein but in our existence time is measured in seconds, minutes, hours, days, etc. It is a constant that does not change regardless of someone's persective. Just because someone feels time went faster doesn't mean that it actually did.

Of course this is science fiction,from a human perspective,because no one has traveled a near light speed,but particles have been proved to experience time dilation during numerous tests and thats science fact...
Time dilation by the Lorentz factor was predicted by Joseph Larmor in 1897,at least for electrons orbiting a nucleus.Time dilation of magnitude corresponding to this Lorentz factor has been experimentally confirmed.Look at the state of the world in 1897,how people were living,what they were doing and look at what Joseph Larmor was thinking about and doing...
When traveling at near the speed of light,which is 186,000 miles per second,time does change,for the person thats moving through space at those mind numbing speeds...
They are traveling so extremely fast that time is dilated "for them" and many thousands of years will pass by "for them" and the closer they travel to the speed of light,the faster more time will go by "for them",the further into the future they will have traveled.While at the "same time" someone else on earth will only experience a few years going by...As amazing as that seems and sounds...That is reality...Not science fiction..

When we sent the first astronauts to land on the moon,we didnt "really know" what would happen to them until after their mission was through and they returned home...
Lots of humans collect and study ants...
If we tried to or had to,how would we be able to communicate with ants,who may be the most intelligent of all insects,what methods would we use?
Would we re-arrange their little piles of sand and pebbles around their holes into distinct shapes and sizes?
What would they think is going on?
What would we be saying to them?
Would they then re-arrange them into other shapes and sizes to try and communicate back to us?
What are we saying to them as we walk on,drive over and crush them all the time?edit on 19-2-2012 by blocula because: (no reason given)

When the transformation was complete and the later sector was safe, the first sector imploded the fusion reactors, destroying 98% of the Dinoid/Reptoid civilizations, the survivors evacuated to the planet in our solar system, Maldek. Now with the Dinoid/Reptoid no longer present on Earth, the Earth Spiritual Hierarchies and the cataceans had to find a suitable guardian for the land. They searched the galaxy for 2 to 3 million years before finding what they were looking for . They found, on the fourth planet of the Vega system , a primitive aquatic species that was starting to emerge from the oceans. This species had creation myths, a language, and a hunting and gathering culture.
The Spiritual Hierarchies of the Vega system were then asked if they would permit this species to be vastly altered genetically to accelerate their evolution so that they may become a guardian species. The Vega Spiritual Hierarchies agreed. So, the traces of the first humans came from the Vega Star System. Their technology improved very quickly, and once they had developed star travel technology they started to migrate into nearby star systems for a period of 2.5 million years.
During this time the Galatic Federation was formed, Sirius B was colonized and Earth was selected for seeding. Later Mars and Venus were colonized and the Hybornea colony was founded on Earth. Dinoid/Reptoids in the meantime had built up there forces and were invading the various colonies throughout the solar system. Hyborean Earth, Mars and Venus were victim to these attacks and the Dinoids and Reptoids gained control over the solar system for a period of approximately 80,000 years.
In response to this the Galactic Federation planned a counterattack to reintroduce humans into this system. They arranged for a battle planet (4 times the diameter of the Earth) to come into the solar system and destroy the planet Maldek - which was the Dinoid/Reptoid stronghold. The remains of the planet Maldek are what we can now see as the asteroid belt. After the destruction of Maldek and the defeat of the Dinoid/Reptoids a human colony was again established on Earth. It is what we know today as Lemuria. Over the next 850,000 years the Lemurians spread across the face of the planet. They founded daughter colonies such as Atlantis, Yu which is now Central China and Tibet and the Libyan/Egytian colonies.
The Atlanteans began to acquire a feeling of uniqueness about their culture and wanted to eliminate Lemuria so that they could become the mother country. The Atlanteans began forming alliances with renegade Pleidans and Alpha Centaurians which had Hierarchical systems of government . They accomplished the destruction of Lemuria by taking the Earth's moon (Earth had 2 moons in those times) out of orbit by using force fields until it was as close as possible to the Lemurian empire, and then the moon was destroyed resulting in a catastrophic shower of meteors. This destroyed much of Lemuria, but this also resulted in many pressures being inflicted upon the tectonic plates : resulting in the gas chambers under Lemuria to implode and thus sink most of the Lemurian continent.

And the ants at the immediate location of the sausage roll were probably somewhat distressed at first when you moved it... Then later realised you helped them.
Is this what's going on here on earth now, or what went on? Perhaps the elite are the only ones who really have a reason to stress about current ET(Ancient Terrestrial) presence. I saw the thread headline recently that china have observed structures on the moon... I havent read it tho
I dont think that they are aliens but rather ancient colonies from Earth's past.edit on 21-2-2012 by Spiratio because: (no reason given)
