are we alone in the universe?

Answer 1

Probably not.

Answer 2

No. Think about the vastness of the universe and all the complexities. I forget what I was watching (I watch a lot of documentaries) but they were trying to figure out the approximate number of planets that could support life, and then from that number, the number of planets that could support life long enough to develop intelligent life. I don't remember the numbers, but as you can guess, they are pretty small. Something like 1 in a billion stars will have a planet with some form of life. The possibilty is out there, for sure, and chances are, we are not alone in the universe. Then again, maybe with the relevance of time factored in....maybe at this point, we are all alone, and say a few billion years ago, there was life somewhere else. The odds are endless. Be your own judge of it. I say there is life out there. I say that they have probably visited us, and some stories of encounters are true. Most are probably fake though. Some people would argue about why they would want to come here and be unseen. My response to anyone wondering that is to think about what we would do if we found life on another planet. I'm sure we'd want to find out things....study the environment, the species, and the natural order of things...along with whatever threat there might be. We'd want to remain stealth until we know it's safe. Why would an ET want to remain unseen? To avoid captivity...possibly death...if discovered by us curious humans.

I think I went a little too in depth and side tracked a little, but oh well...I've got nothing better to do right now.

Answer 3

Absolutely not. You'd have to be a real fantasist to believe that we were the only people in the universe. Like those, here, in the UK, years ago, who didn't even know the USA existed, let alone that there were people there. Just because we haven't got the technology yet to detect any other form of intelligent life, doesn't mean there is none and anyone who can categorically state that there is none, must be very closed-minded.

Answer 4

"The Fermi paradox is the apparent contradiction between high estimates of the probability of the existence of extraterrestrial civilizations and the lack of evidence for or contact with such civilizations.

According to some observers, the extreme age of the universe and its vast number of stars suggest that extraterrestrial life should be common. Discussing this proposition with colleagues over lunch in 1950, the physicist Enrico Fermi is said to have asked: "Where are they?" Fermi questioned why, if a multitude of advanced extraterrestrial civilizations exist in the Milky Way galaxy, evidence such as probes, spacecraft, or radio transmissions has not been found. The simple question "Where are they?" (alternatively, "Where is everybody?") is possibly apocryphal, but Fermi is widely credited with simplifying the problem of the probability of extraterrestrial life. Wider examination of the implications of the topic began with Michael Hart in 1975, and it is sometimes referred to as the Fermi-Hart paradox.

There have been attempts to resolve the Fermi Paradox by locating evidence of extraterrestrial civilizations, along with proposals that such life could exist without human knowledge. Counterarguments suggest that intelligent extraterrestrial life does not exist or occurs so rarely that humans will never make contact with it.

A great deal of effort has gone into developing scientific theories and possible models of extraterrestrial life and the Fermi paradox has become a theoretical reference point in much of this work. The problem has spawned numerous scholarly works addressing it directly, while various questions that relate to it have been addressed in fields as diverse as astronomy, biology, ecology and philosophy. The emerging field of astrobiology has brought an interdisciplinary approach to the Fermi paradox and the question of extraterrestrial life."--wikipedia

To the objective (or open minded ) person there are several possibliities:

1. Earth is unique-- Earth is the only planet capable of supporting life as we know it.
2. Earth is not unique in that there is life elsewhere but there are no other advanced civilizations in the universe.
3. Earthlike planets are extremely rare therefore any advanced civilizations are to far away for us to contact.
3. Earthlike planets are not rare, there are many civilizations out there but they are so far ahead of us technologically that they do not wish to be contacted.
4. Earthlike planets are not rare, there are many civilizations out there but their form of life may be so different than ours that communication may be impossible.
5. The Zoo hypothesis--we are being deliberately isolated by some advanced race wishing to protect us or cultivate us technologically.
6. We have been contacted but our governments feel that the general public is not "ready" for such a discovery and the aliens have respected that viewpoint.
7. They are already amoung us but we cannot see them (deliberate hiding or so differnet that our eyes can't see them)and our government doesn't know.

you can probably add to this list.

Answer 5

Well, it really depends on your perception really. Some scientists believe in the presense of microorganism in other planets because there's water present. Of course, many are still skeptical about this deduction but we have to recognize that certain chemicals like water may lead to the existence of another organism or species. For centuries, we believed in a supernatural being called God. Why? We don't know but maybe He is really there. For centuries, we spotted several UFOs. These things cannot just be some figment of our imagination without reason. So my answer to your question is that we are not alone, whether the "other" beings are supernatural or "real".

Answer 6

Technically, it is a good and interesting question. You already got good answers.

Many people feel alone even within the biggest crowd.
Did you never feel alone ?

The fact is -with the exception of scientists- the possibility of extraterrestrial life gives many people hope. Hope of what ? A miracle ? If we are lucky and find some aliens, we shouldn't expect them to solve our own issues

seriously, who cares ?

Just trying to give a different perspective to a common question

Answer 7

I have seen a group of aliens(5) and there vessel. I was camping
in North Queensland Australia in 1997. I viewed this encounter from about 300 meters away which lasted for approximately 20 minutes. I witnessed scenes so incomprehendable that i can not even begin to explain them. I will always remember it

Answer 8

Given that we have been able to map other galaxies in the universe which is determined to be huge, isn't it just a little arrogant of us to assume that we are the only living things in the universe?

There must be life elsewhere, civilisations that are more advanced than us and some that are not as advanced as us.

Answer 9

With an estimated 100 billion stars in our galaxy and 100 billion galaxies in the universe the chances of their being intelligent life are quite high. The problem with finding any is sheer distance.

Answer 10

If space is infinite is size... then there's an infinite probability of another planet, by a sun, at the right temp to sustain carbon, silicone, or another base form of life. However, you must also consider the possibilty of other life based on string theory, too... life in other dimensions, some that cross over ours.

Answer 11

The answer is almost certainly not. The big question is, though, is there *intelligent* life out there. My opinion is that there is, though maybe not within 90 light years of us. As we have been emitting radio waves for ~90 years, this is how far our earliest radio transmissions have travelled.

Is there life of any kind within this range? I'd be very surprised if there isn't.
