Is there life elsewhere in the universe outline?

Answer 1

There is no way we are the only forms of life in this infinite universe. It would be kinda dumb to think there isn't, they might not be as intelligent or they may actually be far more intelligent than us, but they sure do exist. The possibilities of us being the only ones are slim to none.

Answer 2

1. There is no definitive proof of life elsewhere in the universe.
2. Scientists are actively searching for signs of extraterrestrial life through various methods such as studying the atmospheres of exoplanets.
3. The discovery of microbial life on Mars or under the icy moons of Jupiter and Saturn would significantly impact our understanding of life beyond Earth.

Answer 3

NASA is trying to replenish its inflated budget with expansive, untenable, even nonsensical Propaganda about "life on Mars," adding where there is or was water there was probably life," etc.

Such nonsense is laced with inaccuracies, hyperbole, and sheer fantasy--in fact, anything to bamboozle the public, Congress, even the White House about the "inevitability" or "likelihood" of extraterrestrial life.

Meanwhile, no one cares to ponder this hypothesis with any reflection or depth--say, by reading, e.g., Ward and Brownlee's excellent, sobering study, RARE EARTH. The two authors are not emloyees of NASA and in their book make a specialist's estimate that Earth might be unique in possessing a biosphere.

This idea, by the way, although unopular, is not new. The late, famous Russian astrophysicist Dr. Iosif Shklovsky wrote about this just before he died in the early 1980s.

Shklovsky argued the thesis of a "unique Earth" in possessing life. Sir James Jeans, Einstein, and other eminent scientists have also suspected Earth might be unique in this way.

As to frozen liquid--if it is that--on Mar: It is called by NASA PR "water ice." Haven't we all heard, though, that there are OTHER TYPES OF ICE of a kind that is poisonous and more likely is what lies beneath the surface of that airless, lifeless, clinker of a so-called "world" called Mars? (Water, as Ward and Brownlee point out, is evidently very rare outside of Earth.) There are many types of frozen, formerly liquid acids, for example, or a liquid compound resembling noxious "dry ice"?

Shklovsky, world renown as an astrophysicist, ventured to proipose that we adopt a new "neo-geocentric" point of view about our fragile, very special Planet Earth--meaning, he argued, cultivating an appreciation of the likelihood of Earth's uniqueness.

It's certainly time to critique the lame notion that if there are "billions of Sun-like stars" out there "must be" Earth-like planets orbiting them (Asimov's, Sagan's, Morison's, Shapiro's, SETI's, et al., argument).

This is like saying that if you had billions of chimpanzees pounding on computer keyboards for billions of years, sooner or later there would "inevitably" be some who would write a Shakespearean play or sonnet!

Obviously, this doesn't follow. There is such a thing in philosophy, science, and real life called UNIQUENESS. And that may well be what Earth is.

We hear sometimes that it is "arrogant" to posit Earth's uniqueness. On the contrary. It is the height of metaphysical arrogance to suppose humanoids grow like "cosmic weeds" Universewide. Projecting Earth;s experience throughout the whole Universe is hardly modest!

Anyway, there is no proof of this and much doubt that Earth's likely unique experience could be replicated. Even a World Series game or world soccer match cannot be replicated and theyt are uncomplex affairs compared to Earth's evolution! Each type of evolution, or series of events, is unique, just as each human personality is unique. (The game anaology is admittedly a simplistic example since Earth;s evolution over its 4.5 billion years is vastyly difference, more complex, and has seen far more contingencies, chance and fortuitous events that contribute to its overall likely uniqueness.

By the way, the argument for a unique Earth contains no religious connotations. On the contrary. It has been the religious argument going back to the Middle Ages--namely, that God "in all His plentitude" created many "worlds" populated with humans.

Answer 4

No evidence of its current existence has ever yet been found.

The most favorable findings suggest that there are a few places outside of Earth

where liquid water probably existed at some time in the distant past.

That doesn't guarantee that there was life there at the same time, but without it,

life would have been impossible.

Answer 5

(By "human", I'm assume you mean "like us".) As of yet, no one has discovered any form of extraterrestrial life. However, lack of evidence is not necessarily proof of absence. Considering the vastness of the universe, and the potential existence of other universes, it's quite possible, I'd say, even likely.

Answer 6

Scirntist believe that mars did have microscopic bugs on its surface.

Europia one of Jupiters moons has believed to have some type of fish species different to Earths under its icy surface.

Answer 7

Based on purely statistical arguments, many scientists hold the opinion that life
outside the earth is very likely.
But no evidence of it has ever been observed yet.
If it exists at the present time, we are completely unaware of it.

Depending on an extra-solar civilization's stage of cultural and technological development,
it may or may not be aware of our existence, although the times and distances involved
make that very unlikely.

Answer 8

I think there is life on mars and also in another galxy because we don't know we would be dead by the time we got past Pluto so unless they(if they exist)come to us the answer is no.

imagine if there is life on another planet they might think is there life on that planet over there?(that's us!)

so we might find out soon 'cause NASA sent out stuff to see if there is life on mars.

also i think there is life on the moon about 1million years ago.

Answer 9

Good question. Scientists believe that when you get past earth there could possibly been life on mars along time ago because there is traces of water beds on Nara but for some strange reason mars gravitational Field gave up and the solar winds destroyed its atmosphere which caused the water to evaporate. They also believe that there could be life under the surface of moons because of volcanic activity it puts out enough heat for life to survive. Hope I answered your question, if you have any comments please tell me.

Answer 10

There is nothing outside the universe. The definition of 'universe' is 'Everything and all time'.

Anything that exists is inside the universe.

So let's just consider life outside our solar system.

A majority of those who have pondered the question have generally concluded ... based

primarily on statistical considerations ... that the existence of extra-terrestrial life, either

now or in the past, is almost certain. No evidence of it has ever been observed, however,

mainly because the distances involved are so vast.

(When we caught our first glimpse of the question, we thought it was going to ask about

intelligent life outside the solar system, to which we were prepared to respond: Before we

move on to the larger question, let's consider the probability of intelligent life inside it.)
