Why ufos dont exist

Some segments of the public are more likely than others to believe that intelligent life exists on other planets. This view is especially pronounced among younger Americans. However, men are not more likely than women to believe that the military-reported UFOs are probably or definitely evidence of intelligent life outside Earth. White adults and those who are college-educated tend to be more skeptical than others over the possibility that military-reported UFOs are evidence of extraterrestrial life.

While the intelligence report has received prominent media coverage , Americans were broadly unaware of the assessment prior to its release. From the survey alone, it is not possible to determine whether recent government information itself is making people more likely to believe the UFO reports are evidence of extraterrestrial life, or whether Americans who were already inclined to believe this tend to be among those following the story most closely.

Note: Here are the questions used for this report, along with responses, and its methodology. In times of uncertainty, good decisions demand good data.

Please support our research with a financial contribution. It organizes the public into nine distinct groups, based on an analysis of their attitudes and values. Even in a polarized era, the survey reveals deep divisions in both partisan coalitions. Use this tool to compare the groups on some key topics and their demographics. With billion stars in the Milky Way, many with solar systems, and ten billion years or more in which a civilisation could have arisen in this galaxy, it is difficult to believe that no lifeform ever reached the point where it could travel across interstellar distances.

We have to think outside the box. As soon as big telescopes like the one at Jodrell Bank Observatory were built, scientists realised that if there was a civilisation out there with a similar bit of technology, we might be able to pick up signals sent from one to the other. However, there are so many different ways in which a lifeform might send signals, we could spend our lives looking for them and get nowhere. As well as method of communication, distance poses a huge obstacle.

A message sent from one of these stars would need to travel in the region of 25, years before it even reached us. If alien life is out there, it could take thousands of years before we hear a peep from it. An alien civilisation also needs to exist at the same time as humans. If we want to send physical mass out into the ether, in the form of probes or people, then it gets a lot more challenging. Breakthrough Starshot, a project championed by Stephen Hawking before he died, is exploring the option of using a solar sail — a sheet of metallised plastic that sits in space — to transmit objects into our solar system.

It would involve a huge bank of lasers shooting photons up to hit the solar sail, transfer their momentum, and send the solar sail accelerating off at up to a fifth of the speed of light. Even if lifeforms with technology far more advanced than our own exist, they have to want to make contact.

Any aliens out there may feel apathetic about us Earthlings! And they may not be overly keen on the idea of travelling between the stars for thousands of years in order to get up close and personal. A witty, irreverent look at the world through scientists' eyes. With Robin Ince and Brian Cox. What if we stopped sending signals into the universe - could aliens still find us? And the progress is simply stunning.

So, if you postulate the existence of highly technical civilizations, thousands, much less millions of years in our future, unless the hypothesis strongly contradicts known laws of physics, I think you have to say it's possible.

So, travel at very high speeds between the stars, that's by no means out of the question. Walking through walls is a little tough for me. I don't see how it could be done. And the basic reading program idea of the alien abduction, the paradigm, they seem strangely backward in biology for all their advances in physics, if you take it seriously.

Why are they doing breeding one on one at such a slow pace? Why not steal a few humans, sequence our DNA, look at variations and make whatever genetic engineering changes they want.

We almost have the ability to do that. It seems naive in terms of molecular biology. Precisely because of human fallibility, extraordinary claims require extraordinary evidence. Now, I know that Budd Hopkins responds that extraordinary claims require extraordinary investigations.

And I have two kinds of responses to that. There is a claim that a brontosaurus is tramping through the jungles today in the republic of Congo. Should a massive expedition be mounted with government funds to find it, or it is so implausible as not to be worth serious sustained systematic attention? And my second point is that to the extent that extraordinary claims require extraordinary investigations, those investigations must be true to the spirit of science. And that means highly skeptical, demanding, rigorous standards of evidence.

And it's not a hint of that from alien abduction enthusiasts I think that the alien abduction enthusiasts understand the need for physical evidence. It's the pathway to some degree of respectability. And for 40 years, they've been telling us that real evidence is just around the corner, it's about to be released, it's being studied at this moment - and nothing ever comes of it.

NOVA: Well, now we've run into this alleged alien abduction footage. Have you heard about this? What do you make of the film footage of this alleged animal autopsy? There are several things to notice. One is that the creature in question has a strong resemblance to the alien abduction paradigm, although with six fingers on each hand. It is dissected in a movie taken with lots of blocking of the body and numerous out of focus excursions by the camera.

And the humans involved in the autopsy are all dressed in these 's radiation suits which are covered head to toe and there's just a little rectangular window to look out, which means that nobody can be identified.

The key piece of evidence that it's not a fake is said to be a leader from the beginning of one of the rolls that was—you know, and they're all encoded, and it was submitted to Kodak, the manufacturer. And Kodak came back and said this was shot in or some year close to that.

And that demonstrates that its not a fake. But, an important proviso is that Kodak was not given a reel that had the autopsy on it. They were just given a snippet, give to Kodak, and then alleged that it came from the beginning of the autopsy film. So, I think that it's a clever fake, if it's a fake. But, it's certainly not compelling. NOVA: According to Hopkins and others, the main evidence for these stories—in the absence of other evidence—is the similarity of details.

In your opinion, what other explanations might account for the similarity and the details of the stories or hallucinations of these abductees? SAGAN: The culture contaminates movies, television programs, books, haunting pages of aliens, and television interviews with passionate abductees - all communicate to the widest possible community the alien abduction paradigm.
