ups salah topik deh,

@ Rizki Dwi Rahmadi
klo agama dan sains dicampur aduk bisa2 puyeng ndiri...
klo menurutku sih ada...
ntah d planet yg mana yg masih lom ditemukan oleh manusia...

... mending coba tanyain aja ama yang ada di afsel. kapan hari ada pesawat dari luar angkasa yang mendarat di situ lama. kalo ga salah di district 9.

Kemungkinan adanya kehidupan lain (alien) dalam galaksi kita cukup besar karena ada sekitar 2000 sistem yang mirip dengan sistem tata surya. Dalam alam semesta terdapat puluhan milyar galaksi, sehingga kemungkinan terdapatnya alien sangat besar. Namun sulit berkomunikasi karena di pisahkan oleh jarak jutaan sampai milyaran tahun cahaya.

Jd alien t ada apa tidak? Apa ada penelitian yg mengatakan alien ada atau tidak? Bukankah slama ini hny kepercayaan org bhwa alien t ada atau tidak? Dan mereka menguatkan argumennya dg alasan tnpa adanya bukti eksperimen atau penelitian yah?

Yah, pokoknya kalau belum pernah ngeliat alien atau belum pernah melihat bukti keberadaan alien bukan berarti alien itu ga ada

hehe...aneh juga ya kalo dibahas....
selama ini yg ditemukan hanyalah fiktif dan rekayasa aja....
tp beberapa bulan yg lalu, saya pas nganter kakak di bandara juanda, diarea parkiran melihat lingkaran bercahaya cukup terang, terbang diam, bahkan kakak saya juga melihat. lumayan lama kira2 2 menitan. lalu tiba2 menghilang. kejadian ini berlangsung menjelang maghrib.
dan kebetulan, ditetangga tmn sy jg mengalami hal yg sama. pd hari itu juga dn ditempat itu juga..!!
entahlah...,benda apa td....

Quick Technical Overview: What we think we know about UFOs



Heflin, Santa Ana, California USA 1965 photo depicts a flat-top "straw hat" saucer - magnified photo #1, all 4 photos @ rr0 (french). To the general public, it is perhaps the best known shape of what a UFO may look like, as it was included in encyclopedia Britannica's 1966 yearbook, classified under "spacecraft".

Story: On 3-Aug-1965 about 12:30pm, Rex E. Heflin, age 38, a highway maintainance engineer for the Orange County road department, spotted an unusual object approaching the road. He stopped his truck, grabbed the camera off the seat beside him and shot three pictures as rapidly as possible. As the object moved away, Heflin scrambled out of the truck and took his fourth and final picture of a "smoke ring". Heflin tried to contact his office by radio while the UFO was near his vehicle, but the radio refused to operate. Heflin estimated the UFO to be ~20ft (6m) in diameter and ~700ft (210m) away and said a rotating light was apparent underneath the UFO. [case file @ nicap, ufoevidence, ufologie, rr0 (french)]

Second generation copies of Helfin's photos (the originals were taken from him by two men claiming to be from NORAD) were repeatedly analyzed at the time, by NICAP, by atmospheric physicist Prof. James McDonald and others. With some exceptions (e.g. Dr D.Rudiak), the consensus among UFO researchers is that these photos show an authentic UFO. Latest re-analysis of Heflin USA 1965 (.pdf) published in 2000 in JSE includes all 4 photos.

Related: The UFO in the Heflin photos resembles those photographed in Kluj Romania 1968, Belotie Yugoslavia 1974, Kosina, Hungary in 1996cases. Other cases describing similar objects is the A.C. Urie, Snake River Idaho USA 13-Aug-1947.

Watch: Heflin interview 30 years after the event. He sticks to his story and maintains the authenticity of the photos.

Lynn, MA USA 11-Dec-2006 by Fredrick N., two photos of a dark oval/egg-shaped UFO (which is one of the common shapes seen near the ground since the 1950s), flying with the long axis vertical, taken with a digital camera.

Witness story:
My kids and I saw this incredible UFO in the eastern sky on Dec 11th at around 5 pm. No sound just moving back forth up and down then exited. [full story and bigger photos]
Note: Erratic, violent maneuvers are the distinct characteristic of UFOs. Eye witnesses may use terms like "zig-zagged", "zipped around", "hopped around", "dancing around", "bobbed and weaved", "yo-yo'ed" etc.

These two photos will help us to visually identify certain (speculative) concepts about UFOs (covered in sections #7, #8 and #9 of the main part of this page, and the extract from P.Hill's book on UFO illumination and colors).

Notice that both photographs show a bluish glow under the UFO (which is often interpreted as "flames" or "exhaust fumes" by eyewitnesses). This illuminating sheath of atmosphere around the UFO is a sheath of ionized and excited air molecules, known as "plasma" in scientific literature. This plasma is generated by EM radiation accompanying the UFO's force fields, used for propulsion and air-control.

Because of the difficulty of creating plasma at normal atmospheric pressure and temperature, in addition to other confirming observations, such as a) the luminosity of some reported submarine UFOs b) the sudden appearance of "mist" or "cloud-like substance" around UFOs when they startup in high humidity environment, apparently as water vapor adjacent to the UFO is condensed by pressure from a force-field c) the occasional violent sound effects (roar) at startup, while being practically silent in flight d) and the physical effects as UFOs enter/exit the water it seems that UFOs "airflow control force field" (ACFF) creates an envelope of lower atmospheric density (vacuum) near the UFO's surface, by pushing the surrounding medium (air/water) away from the skin of the UFO.

The basic idea is that UFOs prevent aerodynamic heating, reduce drag and suppress shockwaves (sonic boom) by utilising their acceleration-type force field technology for propulsion, as well as for controlling the surrounding air (or water). Hill refers to the latter as "airflow-control field". Another way to think of it is using the same principles as a incandescent light bulb: UFO craft is the filament and the bulb is the air-control field around it, which protects the UFO, keeps the surrounding medium (air/water) from coming in touch with the UFO. This minimizes friction and heating issues.

Below: In the #2 photo, note that the three (3) bluish neon-light-like glowing areas appear at some distance around the underside of this oval craft, and are spaced at 120° apart. [better visible in 2nd photo enlargement] It is not the UFO itself emitting light, but an envelope of ionized air (a/k/a "plasma sheath") around it. Interpreting this photo according to the ideas outlined in section #8 on Radiation, i.e. that UFOs' ionizing EM radiation (which creates the glowing plasma), is coincident with the UFO's gravity-like force-fields, the 3 zones of glowing air below this UFO may be revealing the position and direction of the propulsive fields of this particular UFO at that moment in time.


The Japanese pilot lost his flying status for reporting the incident to the public, but 15 years later the story was corroborated by Callahan, former FAA Head of Investigations in DC. FAA administrator Donald Engen briefed members of President Reagan's Scientific Study Team, the FBI and the CIA in Washington, D.C. We know the details today because John Callahan, Division Chief of the Accidents and Investigations Branch of the FAA, attended the secret meeting and saved all audio and video evidence of the event (src: Callahan testimony at Disclosure Project's Press Conference in 2001):

Lake Cote, Costa Rica 1971: A disk / shallow cone "conical hat" was auto-photographed in 1971 by a Costa Rican government mapping plane during an aerial mapping mission.

The photo came to light in the 1980s, thanks to one of the crewmen who contacted local Ufologist Ricardo Vilchez. In 1985, a 2nd generation negative got in the hands of Dr. Jacque Vallee, who along with Dr. Richard Haines conducted an analysis which was published in JSE ("Photo Analyses of an Aerial Disc Over Costa Rica" (.PDF) and New Evidence (.PDF)).

People have seen objects emerge from the lake in subsequent years.

Related: Two similar UFOs, described as huge 600-700ft conical "coolie hats", were reported in a multi-witness encounter by the crews of 3 US Navy fighter bombers in Sep-1950 over Korea [more]. Another similar case is Lake Michigan 1981.

Summary: This page covers the subjects of UFO shapes, types, colors, illumination, flight characteristics, speed, rotation, wobble, radiation, maneuvers, sounds, landing traces etc, with annotated examples of photographic cases of UFO sightings. This webpage aims to help the reader make some "technological sense" out of certain aspects of the UFO pattern (in particular sections #7, #8 and #9 covering UFO propulsion, radiation and illumination respectively). On a personal note, having spent considerable time researching the UFO subject, in this page I'm including the info which I personally would like to have found, when I first started looking into UFOs. This page would have saved me a lot of time. Some of the concepts are technical, but I've tried to present them in a language which nearly everyone should understand.
