Different opinions should always be present when several people are taking part of or participating in a project.

One specific opinion is always that of an individual. Different opinions and attitudes will always be around when being a member and taking part.

A given or specific result is therefore expected to be reached by means of consensus.

Astronomy alone, let alone astrology or the like, probably will not be able to tell the whole story or the truth about whether or not we are alone in the universe.

Our knowledge about religion is that it is telling us about the difference between right and wrong, or possibly good versus bad. What is supposed to once have been God's representative here on earth become both admired as well as feared by a couple of people as well, because he was supposed to be doing miracles and also giving us lessons by means of preaching by telling about his father, God.

Today's scientists are not concerned about religion and the spiritual, most likely intentionally so, because this is not supposed to go well with our general approach when it comes to dealing with subjects related to science.

Even though not everything can be readily explained, scientists typically find it hard to explain certain things by means of associating those things with religion or the supernatural. Rather, an explanation is being sought by means of the subject of mathematics and physics. Next comes the appoach of logical and reasonable thinking, which might imply deduction at times.

Theories are often proven in this way. It is the result of the deductive and analytical minds of certain people, like Newton and Einstein, that is paving the way for a better understanding of nature and the way it is supposed to work.

In the same way, there should be an explanation for the UFO phenomenon as well. Many scientists are guessing that these objects are being related to the possible existence of extraterrestrial intelligence, but apparently this phenomenon has yet to be fully understood.

As a race modern man the builder dont fit in nature like our predecessors that were a gather hunter for 300 million years then An ice age Neanderthals survived 120,000 years of hard ice age. Modern man has traced back 14,000 years and that way too fast for modern man the builder,the scientist,we alter our environment to suit us. If anything man is a virus infesting a rocky world that it so rare we have to ask why not life like us everywhere. ET is not among the 1000 nearest stars from 4.5 lightyears to 29,000 lightyears out from earth. The drake equation is wrong because planets in habitual zones are so very rare maybe 3 out of 3500 exoplanets found are maybe 3 habitual planets. None show signs of methane nor radio emissions or IR of surface life. This makes it impossible for any alien race getting to earth. All stars are millions of years travel from the nearest worlds. Radiation alone would make it lethal after a few years exposure. The most to over come is the solitude and the danger. Man cant survive the radiation and out frail bodies cant endure space for more than a year without severe problems.
This makes ET an impossible of getting to the earth to travel from the travel from the nearst stars is impossible distances that require millions of years in space. ET is very far away and impossible just to traverse this distance just food and air to breathe and water for centuries of space travel doesnt compute.

well, maybe they live on a moon of some jovian planet? there are plenty of those around a habitable zone...

also, it's imposible until someone does it! so no, NOTHING is imposible!

I can't see the linkge with all the UFO & lack of sound...nobody who sees UFO hears a sound, even in flight of UFO...especially when UFO vanishes in "great speed"...

Hm...talk about delusions, are we? ;)

It is not just a question of "where" ET is, but when.
We humans have only been present here for a very brief period of time (compared to the age of the universe).
There might have been civilizations, that vanished thousands of years ago.
So, to add to the problem of finding ET, we have to consider, when ET is or was.

Chris, definitely you are not a believer of UFO's, but perhaps you still may consider the possibility of other extraterrestrial civilizations being present in space.

As our understanding of the universe is continually evolving and expanding, original theories based on Newton and Einstein when it comes to gravity, space and time is being replaced by other theories as well, including String and Quantum Theory.

Every theory that might around and supposed to be based on the laws of mathematics and physics are supposed to be based on our fundamental notion of how the universe is supposed to be working.

Here is the following question for you.

Is it possible to assume that the laws of the universe are based on the notion of "predictability" vs. unpredictability?

Could something or anything either be excluded or possibly disregarded by giving this a thought and possibly be making any assumptions from the same?

If you are having the time, you may listen to an Art Bell "Coast to Coast" radio interview, featuring Seth Shostak.

Saw this very interesting post on a forum I was recently admitted to:


Einstein saves the quantum cat

Einstein's theory of time and space will celebrate its 100th anniversary this year. Even today it captures the imagination of scientists. In an international collaboration, researchers from the universities of Vienna, Harvard and Queensland have now discovered that this world-famous theory can explain yet another puzzling phenomenon: the transition from quantum behavior to our classical, everyday world. Their results are published in the journal Nature Physics.

In 1915 Albert Einstein formulated the theory of general relativity which fundamentally changed our understanding of gravity. He explained gravity as the manifestation of the curvature of space and time. Einstein's theory predicts that the flow of time is altered by mass. This effect, known as "gravitational time dilation", causes time to be slowed down near a massive object. It affects everything and everybody; in fact, people working on the ground floor will age slower than their colleagues a floor above, by about 10 nanoseconds in one year. This tiny effect has actually been confirmed in many experiments with very precise clocks. Now, a team of researchers from the University of Vienna, Harvard University and the University of Queensland have discovered that the slowing down of time can explain another perplexing phenomenon: the transition from quantum behavior to our classical, everyday world.

How gravity suppresses quantum behavior

Quantum theory, the other major discovery in physics in the early 20th century, predicts that the fundamental building blocks of nature show fascinating and mind-boggling behavior. Extrapolated to the scales of our everyday life quantum theory leads to situations such as the famous example of Schroedinger's cat: the cat is neither dead nor alive, but in a so-called quantum superposition of both. Yet such a behavior has only been confirmed experimentally with small particles and has never been observed with real-world cats. Therefore, scientists conclude that something must cause the suppression of quantum phenomena on larger, everyday scales. Typically this happens because of interaction with other surrounding particles.

The research team, headed by Brukner from the University of Vienna and the Institute of Quantum Optics and Quantum Information, found that time dilation also plays a major role in the demise of quantum effects. They calculated that once the small building blocks form larger, composite objects - such as molecules and eventually larger structures like microbes or dust particles -, the time dilation on Earth can cause a suppression of their quantum behavior. The tiny building blocks jitter ever so slightly, even as they form larger objects. And this jitter is affected by time dilation: it is slowed down on the ground and speeds up at higher altitudes. The researchers have shown that this effect destroys the quantum superposition and, thus, forces larger objects to behave as we expect in everyday life.

Paving the way for the next generation of quantum experiments

"It is quite surprising that gravity can play any role in quantum mechanics", says Igor Pikovski, who is the lead author of the publication and is now working at the Harvard-Smithsonian Center for Astrophysics: "Gravity is usually studied on astronomical scales, but it seems that it also alters the quantum nature of the smallest particles on Earth". "It remains to be seen what the results imply on cosmological scales, where gravity can be much stronger", adds Brukner. The results of Pikovski and his co-workers reveal how larger particles lose their quantum behavior due to their own composition, if one takes time dilation into account. This prediction should be observable in experiments in the near future, which could shed some light on the fascinating interplay between the two great theories of the 20th century, quantum theory and general relativity.

SETI is worthwhile. However: unsubstantiated and disingenuous, wild claims are unbecoming from those whom are smart enough to know better.

No ET that could conquer space travel would be that stupid to risk being shot down.


That's logical the way our brains look at things, but how can we assume that's the way ET's think?

That's logical the way our brains look at things, but how can we assume that's the way ET's think?

At last a sensible question!

Well, space travel to any lifeform would presumably mean a large G force upon lift off, time in interstellar space, a drive of some sort to power the spacecraft, and a landing either on land or sea, or an orbit of a planet somewhere. i.e. pretty upmarket technical expertise which in turn leads to pre-supposed high intelligence. If they ARE here and quietly observing us, they clearly don't want us to know that, well at least not that openly anyway, so it is unlikely that they would use manned crafts and risk a technical malfunction or a capture to give away their presence.

Although a captured ET craft of any description would pretty much give the game away! (Area 51 anybody?).

I therefore submit that it is reasonable to assume that the word "unlikely" in bold above is a fair comment upon any intelligence that has conquered space travel as we know it.



Yes, I see your point, and I tend to agree, but maybe these ET's are just out joyriding. ;~)

I think that it is fair to say that in the near future we can put this "We have been visited "stuff to rest. If we haven't already; we will soon have searched for truly Earth-like planets around all stars out to 100 light years as well as promising moons. If there are in fact any "Habitable" planets that we find we can then concentrate our SETI efforts on these ones.

We will probably not find other venues at these distances with all of the necessary conditions for intelligent life to form. If we do; we won't detect any transmissions or other signs of life if they are not intentionally sending out a focused "we are here" message. if they are then we would have heard them by now.

Speculating that multi-decade trips have been undertaken from these distances and beyond just doesn't make good sense.

To support the notion that life will spontaneously arise in a fertile environment then we desperately need to confirm life on Mars. Either microbial or plant life--perhaps now long extinct.
