Extraterrestrial UFOs: Yes? No? Maybe?

[Corvus]

Our technology is limited but how about our science. Can anything travel faster than light? With the nearest planet according to the op 4.24 light years away. That means your in the transporter beam for quite a long time.

No thing can go faster than light, apart from hypothetical Tachyons, but if you can construct a stable wormhole, between two points in the universe, wide enough to pass a spaceship through, you won't have to worry about light speed. Although I am not sure how you build a functional wormhole big enough, Michio Kaku might.

Even in Star Trek they were directly above the planet when they used the beam. If you used a rover type vehicle to explore, you are still talking 4.24 years before communications say to change course.

Time dilation effects mean that passengers traveling close to light speed will experience a significantly shorter passage of time, relative to those on planet Earth.

This simple equation is used for calculating the time dilation experienced by a moving object.

t = t0/(1-v2/c2)1/2

t = time observed in the other reference frame

t0 = time in observers own frame of reference (rest time)

v = the speed of the moving object

c = the speed of light in a vacuum

So if you were to travel the 4.3 light years to Alpha Centuri, if you could travel at say between 97-99% the speed of light, it would appear to an Earth bound observer you have taken over 4.3 years to get there. However from your observation point on board the ship, with a time dilation factor of around 8, the ships's clocks would record that just over 6 months has passed.

EDIT I think I misread your post and responded unnecessarily, you don't need remote control Rovers, Autonomous Robots will do nicely.

I watched several programs this evening titled, "UFOS: Uncovering the Truth." One episode, "Deathbed Confessions," dealt with government employees who in their last days confessed to UFO evidence they were sworn not to reveal. Another episode dealt with astronauts and pilots who who encountered UFOs; UFOs that did not appear to have an earthly origin, or were optical illusions. The last episode, "Ancient UFO landings" was about evidence of the possibility that extraterrestrials visited Earth years ago and passed along advanced technologies. Looking up the series online I see there are five episodes in all.

So far the presented evidence is quite compelling; however, given that no other planet in the solar system except Earth is currently capable of sustaining life, and the distance to the next closest star, Proxima Centauri, is 4.24 light years away, I find the idea of extraterrestrials visiting Earth pretty ludicrous.

What do you think?

While anything is possible, the best explanations I've heard for not having been visited by aliens is that space is far too big for any interstellar travel to be feasible or practical. Even if that hurdle is overcome and FTL travel is achieved, where ya gonna go and what ya gonna do when ya get there?

Even if we find a planet capable of supporting life, there's no guarantee it can support our life. Our life evolved and adapted to live here on Earth. We might find another planet with life on it, which would support life which evolved there - but it could still be poisonous or otherwise uninhabitable for any Earth-based species. And our planet could be just as poisonous to any alien forms of life from another planet.

What "experts" say this? Why would they come here?

I watched those shows too and voted 'Yes'. You didn't mention one other discussed thing above that we humans are hybrids; ancient humanoid enhanced with alien DNA technology (the missing link). We are even part alien (to the skeptics facepalms). I even would speculate seeding aliens and not abiogenesis occurred on earth. Some scientists say that DNA is estimated to be about 10 billion years old (older than the earth).

So far the presented evidence is quite compelling; however, given that no other planet in the solar system except Earth is currently capable of sustaining life, and the distance to the next closest star, Proxima Centauri, is 4.24 light years away, I find the idea of extraterrestrials visiting Earth pretty ludicrous.

Distance can be traversed almost instantly with advanced technology and even interdimensional travel (I'm sure they are not burning fossil fuels to get here). As for sustaining life, I think we need to get outside the earth physical box and ask what life is. We may just be life crafted for a physical earth environment.

And our planet could be just as poisonous to any alien forms of life from another planet.

I don't think our future involves colonizing worlds that already have ecosystems, that would be extremely problematic to say the least, unless we engineer ourselves to be compatible with an alien ecology and the chemistry of the planet/moon in question. Rather I suggest we would terra-form dead worlds or build domed cities, isolated from the atmosphere, or tunnel into mountains or underground as we plan to so with Mars and other worlds with hostile environments and/or construct permanent orbital habitats in space, complete with hydroponic farms, labs, fabrication plants, recreation areas, residential quarters and all the rest. I favour the latter because you could build them close to stars and thus have access to unlimited solar energy plus you have space station base for mining and other operations system wide. Also you could move them about, away from danger, such as incoming space debris and other hazardous objects or even use them to travel slowly to distant star systems, like futuristic Arks.
This is why I doubt aliens would come to conquer this planet, if they had the tech to get here, then there is very little we have in the way of natural resources that are not readily and easily available floating around in comets and asteroids, as you say any organic matter would very likely be highly toxic to any alien creature able to breath our atmosphere at the pressure and temperature it is in the first place, bacteria, pollen and fungal spores etc...would be a serious issue.

And in the same respect, we know that "heavier-than-air flying machines are impossible" --Lord Kelvin (1895).

If you built a stable worm hole near earth shouldn't we be able to detect it especially if it keeps opening and closing. 6 months is still a long time for life to exist and it would still be 4.3 years for communication to go back and forth which even an Autonomous Robot would have to do eventually. Also an autonomous robot would be pretty easy for humans to find.

An informed opinion is based on the evidence, not on "first principles".

I'd say it's something worse than naive to dismiss or ignore the evidence of UFOs classified in the 1999 report by the French COMETA--a committee of scientific and military experts and pilots commissioned by the Institut des hautes études de défense nationale (IHEDN) for the purpose of in-depth study of UFOs (UAPs)--as Category D “radar/visual” incidents, in which there was a visual sighting associated with a radar detection. This Report found that in 62 countries from 1948-1999, there were 101 such Category D radar/visual incidents. COMETA Part 1 and Part 2.

Probably the best documented of such incidents is the March 30-31, 1990, sightings in Belgium, where multiple, independent and credible eyewitnesses, including members of the gendarmerie, reported aerial phenomena in the same vicinity as contacts on three different radar systems, which showed the radar contacts performing maneuvers impossible for human-made aircraft to perform. The Belgian Air Force report by Major Lambrechts, VS 3/Ctl-Met 1.

I would love it to be true. I'm not convinced though.

UFO witnesses include USAF commanding officers, US and UK and German Radar operators, Police officers from numerous nations, Fighter pilots, Civil pilots, Naval captains, British astronomers...the list of credible sources is considerable. There is also a wealth of other secondary evidence, aside from testimonials, including images captured on film digital and other formats. There are hundreds of de classified documents that relate to UFO activity, many are heavily censored, some files have never been released despite requests under freedom of information laws. Technically the only physical evidence we have (as fas we know) is in the form of radar records of UFO contacts.

True, every point. Indeed, besides the radar contact, there is a photograph of the Belgian UFO that, according to several experts who examined it, is extremely unlikely to have been faked (and wasn't faked in the way that one hoaxed claimed to have done 20 years after the sightings).

Possibly, I am sure there would be a way to conceal any signature emission of energy,

ALIENS EXIST

 

[Shadow Wolf]

I believe intelligent life probably exists out there, I believe interstellar space travel would be possible with advanced technology. But I really can't do anything other than believe, and I am forced to acknowledge the "unidentified" part of UFO whenever anyone claims to have seen something or I see something myself that I don't know what it is.

No, experts have said, if there are aliens, they would come here.

Stephen Hawking gave a chilling prediction that would be end something like how it did for the Native Americans when Europeans showed up, with us being the natives and the aliens being the Europeans.

 

[Corvus]

Many people think they have been coming here for thousands, maybe millions of years. I have to admit there are some reasons to sympathize with that view.

 

[Corvus]

Any alien species that has the technological power to get here, could wipe us out with a mere nod. It would be like throwing sticks and stones at a modern tank, any resistance would be practically futile.

 

[The Holy Bottom Burp]

Damn, the "Eh, maybes" are way ahead! Come on you lazy sceptics! Seriously though, you clearly believe there is something to this; why do you think a visiting alien species would not want to introduce itself? Is it the old "waiting until we get advanced enough" idea? No attempt at ridicule, serious question.

I didn't say anything about "a visiting alien species". The maneuvers of the Belgian UFO(s) recorded on radar would have killed a human. I don't make the assumption that an extraterrestrial UFO necessarily contains an alien species.

OK, so what was the Belgian UFO doing in your opinion? A probe? A scouting mission? Just asking, I don't know how 'Ufologists' rationalise. Just asking questions mate.
