We ARE alone: Despite discovering more planets, the chances of finding ET are unlikely, says astronomer

Still waiting for little green men to make contact? Don’t hold your breath.

A leading astronomer has concluded there probably aren’t any aliens out there – meaning we are entirely alone in the universe.

Even though there may be tens of thousands of other distant planets similar in size to Earth, the conditions on them are likely to be too hostile to support life-forms such as ET. Dr Howard Smith, a senior astrophysicist at Harvard University, believes there is very little hope of discovering aliens and, even if we did, it would be almost impossible to make contact.

So far astronomers have discovered a total of 500 planets in distant solar systems – known as extrasolar systems – although they believe billions of others exist. But Dr Smith points out that many of these planets are either too close to their sun or too far away, meaning their surface temperatures are so extreme they could not support life. Others have unusual orbits which cause vast temperature variations making it impossible for water to exist as a liquid – an essential element for life.

Dr Smith said: ‘We have found that most other planets and solar systems are wildly different from our own.

‘They are very hostile to life as we know it.’ ‘The new information we are getting suggests we could effectively be alone in the universe.

‘There are very few solar systems or planets like ours. It means it is highly unlikely there are any planets with intelligent life close enough for us to make contact.’ But his controversial suggestions contradict other leading scientists – who have claimed aliens almost certainly exist.

Only last month Professor Stephen Hawking said the fact that there are billions of galaxies out there made it perfectly rational to assume there were other life-forms in the universe. Researchers from the University of London have recently suggested that aliens could be living on as many as 40,000 other planets.

But Dr Smith suggests that such estimates are optimistic.

I figure that although anything is possible as far as life on other planets is concerned. I also am skeptical of most claims of contact with alien life forms.

This kind of brings a paradox into the debate because this binds science's hands a bit. By saying we are alone kind of kills their notion that there is no divine force in the universe who put us here(God) because if you're a true analytical scientists, just sheer mathematics would tell you that there is life on other planets somewhere. So, either there is a God who created the earth then man in His own image or there are other worlds who were created by the same set of mistakes and happenstances that created us.

I would be willing to bet American money that life exists elsewhere in this solar system (I would bank on Europa, if pressed).

The problem is sentient life evolving at the same general rate that we have in order to have "contact" be effective (what is our window? a couple of centuries, maybe?) and there is also God's Picket Fence (186,000 miles per second ... it's not just a good idea ... it's the law) that keeps away the overlap of any reasonably advanced life.

The aliens were unavailable for comment.

That's why NW when you look at UFO cases you must go through all the evidence; witness statements, and physical evidence. Some cases really do drop surprises when least you expect them.

The Carl Higon case in 1974 had a 7mm round which he fired at group of five elk, as described it " the bullet seem to float and then fell to the ground at fifty feet away." It was then he heard a twig snap , turned around to see a humaniod coming his way. Higon was taken back to the ship, taken on a flight, and returned. He suffered from confusion and was found by local authories a few hours later after calling for help by means of radio in his truck. After a hospital stay, Higon was able to present to the Sheriff's department and investigators the one piece of evdence he was able to save; the 7mm round that he had fired at the begining of the encounter. One of the deputies said the round had looked like it had been turned inside out. As of 1994, the round has since disappeared.

Is that when Zarathustra told you? Because He spoke about it almost a century before.

All these worlds are yours except Europa
Attempt no landing there
Use them together
Use them in peace

My personal belief is that there is other life out there. Some probably more advanced than us. That little light speed thing comes into play as far as contact goes though. Even if a species had broken the light barrier, they would then have to know where to look for us, problematic with the vastness in which to search.

But Dr Smith points out that many of these planets are either too close to their sun or too far away, meaning their surface temperatures are so extreme they could not support life

So we know for sure that there is at least 1 planet in the galaxy capable of supporting life. In our own solar system we have just 1 in 8 planets capable of supporting life, if you discount Pluto as a planet. However, even if the ratio of extra-solar planets capable of supporting life is 1 in a million, or even 1 in a billion, that means this galaxy is alone is teaming with life. I think the astronomer who thinks that because we've looked at 500 planets and none of them are hospitable, that somehow makes life so rare as to exist in only one place in the universe is kind of off his marble.

Even if a species had broken the light barrier, they would then have to know where to look for us, problematic with the vastness in which to search.

These two things, taken together actually bring an ill omen to the human race. If life is discovered elsewhere in our solar system, that means that life is at least twice as abundant as originally thought. Combine that with the fact that we haven't been welcomed or attacked, or even glanced at by space travelers, and that brings about a couple of conclusions. First, a species that had broken the light barrier somehow would most definitely know where to look for us. We are very far behind that sort of technological marvel, but even we, with our current technology can find extra-solar planets by observing the effect of their gravity on their star. Once we get to the point where we are going to try to have a go at God's speed limit, I think we'll be very adept at mapping extra-solar plants. So, our space traveler friends do have a pretty good idea of where to look, and if life is found elsewhere in this solar system, that means a couple of things. It could mean that light speed can never be obtained or broken, so generation type ships are the only way to travel the vast distances. It could also mean that along the way to breaking the light speed barrier, each intelligent species that has ever existed has run into some event that did the species in before they could travel to other planets and spread their eggs around several baskets.

Right now, since Earth is the only place we know of that life exists, we can reason that life in the universe is extremely rare, if not unique to Earth. That means that there is a chance that we can progress to inter-stellar flight without some sort of apocalypse preventing us. If we find life on Europa, for example, than the likelihood of the species survival up to the point where we can travel between the stars is very low.

The truth is: we don't know. It is the sheerest arrogance to believe that out of the uncounted millions of worlds, we are the only life. Until we mature as a race, the chances are that if there are advanced races, they are waiting for us to be ready. We are children, wondering what lies beyond the end of the street. Do I know they exist? No

Do I think they are there? Yes. Will they contact us or will we meet them someday? Not for many centuries.

In our lifetimes? No.

My belief is that we are effectively alone in the universe.

If there is unintelligent life outside the solar system, we will never find it.

If there is human-scale intelligence outside the solar system, we might contact it, but we could never reach each other.

I think aliens much more intelligent than humans have been running recon on us since antiquity, but they don't wish their presence to be widely known, so it's effectively the same thing as them not even being there.

Is there other life in the universe? Of course. But it's all either hidden or hiding, so there may as well not be any.

My two bits, sure to irritate a few readers. We are definately the only intelligent life in the universe. Why? Because being the only intelligent life in this vast varied universe is more evidence of God's intentional design. We keep finding more and more planets, space, ect, but the lack of intelligent life, IMHO, is further proof that we are not random chance, but purposefully and wonderfully made.

Yup, my theory depends on a lot of faith, and is difficult, if not impossible to prove scientifically. But that's fine by me. That's why it's a theory. :D
