Aliens/Humans from other planets - Do they exist or not??? Discuss

[zaraki kenpachi]

As the title says, do you believe that we're alone in this vast universe? Let me tell you this, if you believe that the we, Earthlings (not counting animals), are the only beings in the entire universe then you are really not seeing the picture.

Do they exist? Have you ever seen something suspicious? And I mean you yourself, not you via youtube, images, newspaper, etc.

I have.

But I'll post it after someone else posts here.

Please don't say stupid things like, yeah I've seen one and he died last week, or anything of that kind :s

[Sasuke_Itachi]

there is no way we are alone out here the universe is so huge we can't be the only earth out there

and yeah I have

[YondaimeRaikage]

could be a multitude of other universes, but unless they came here first we will never see them, because even if there is life we can't hope to travel there in a lifetime.

I guess theoretically we could send a few sets of Males/Females on a ship, and then near the end of their lifetime have them reproduce the next crew.

But there are many Variables and possible flaws in the situation. Too many for our government to issue the mission.

Even still Fuel would be limited.

lmao love the idea space sex
and also what about air they would run out
unless we first set up check points for the ship to refuel along the way and then it could work, I might send that idea to nasa !!

[Suigetsu Hozuki]

i think they exist^^

but its not like i really care they on their planets and we on our ._.

[Sasuke_Itachi]

I just want to know if they are humans
or if the are like different looking or have weird powers

[Suigetsu Hozuki]

hm yeah i also want to know that

[Sasuke_Itachi]

its the weirdest thing that i could think that i want to now about other life forms lol i wanna know

The alien and UFO phenomenon is so widespread and present in our modern times that it looks difficult to make even a cautious opinion. This monstrous category includes such various items as abduction, unknown races, crop circles, strange lights in the sky and a formal synthesis is almost impossible.

I actually wrote a paper on this conserning the Drake Equation

(Okay these are my assumptions and theories regarding the drake equation so there might be some errors)



Some state that by making what they feel are reasonable assumptions and arguments we can ascertain that if life is possible at all, then the universe is so vast that it should not only be possible, but almost certain that there are large numbers of extraterrestrial civilisations in the Universe. In the early 1960’s Frank Drake sought a way to calculate the probability of finding other intelligent races. He came up with an equation to calculate the possibility of extra terrestrial civilizations; which became known as the ‘Drake Equation’. Drake writes, 'The basic premise behind the equation is that what happened here will happen with a large fraction of the stars as they are created, one after another, in the Milky Way galaxy and other galaxies. People unfamiliar with the accepted pictures of cosmic and biological evolution might think the equation is highly speculative; in fact, it is just the opposite, since the phenomena it assumes to take place in the Universe are only those we are sure have taken place at least once' ('The Drake Equation: A Reappraisal', pp. 115-18, First Contact).
Here is the equation also known as the Green Bank equation:
N=R*FpNpFlFiFcL
N = the number of technological civilizations in our galaxy
R* = The rate of formation of suitable stars
F(p) = the fraction of stars having planets.
N(e) = the number of suitable planets per planetary system.
F(l) = the fraction of planets on which life develops
F(i) = the fraction of life that evolves to intelligence beings.
F(c) = the fraction of intelligent species to develop the means of communication.
L = The length of time such civilizations release detectable signals into space.

Drake and other early extraterrestrial-life enthusiasts, including Carl Sagan, arrived at a value for N between 100,000 and 1,000,000--still only about one technological civilization per million stars in the Milky Way, which astronomers believe contains some 200 billion stars.
Drake equation parameters
Considerable disagreement on the values of most of these parameters exists, but the values used by Drake and his colleagues in 1961 are: R* = 10/year, fp = 0.5, ne = 2, fl = 1, fi = fc = 0.01, and L = 10 years.
The value of R* is the least disputed. fp is more uncertain, but is still much firmer than the values following. Confidence in ne was once higher, but the discovery of numerous gas giants in close orbit with their stars has introduced doubt that life-supporting planets commonly survive the creation of their stellar systems. In addition, most stars in our galaxy are red dwarfs, which have little of the ultraviolet radiation that has contributed to the evolution of life on Earth. Instead they flare violently, mostly in X-rays - a property not conducive to life as we know it (simulations also suggest that these bursts erode planetary atmospheres). The possibility of life on moons of gas giants such as Europa adds further uncertainty to this figure.
What evidence is currently visible to humanity suggests that fl is very high; life on Earth appears to have begun almost immediately after conditions arrived in which it was possible, suggesting that abiogenesis is relatively "easy" once conditions are right. But this evidence is limited in scope, and so this term remains in considerable dispute. One piece of data which would have major impact on this term is the controversy over whether there is evidence of life on Mars. The conclusion that life on Mars developed independently from life on Earth would argue for a high value for this term. In 2002, Charles H. Lineweaver and Tamara M. Davis (at the University of New South Wales and the Australian Centre for Astrobiology) estimated fl as > 0.33 using a statistical argument based on the length of time life took to evolve on Earth.
fi, fc, and L are obviously little more than guesses. fi has been impacted by discoveries that the solar system's orbit is circular in the galaxy, at such a distance that it remains out of the spiral arms for hundreds of millions of years (evading radiation from novae). Also, Earth's very large, unusual moon appears to aid retention of hydrogen by breaking up the crust, inducing a magnetosphere by tidal heating and stirring, and stabilizing the planet's axis of rotation. In addition while it appears that life developed soon after the formation of Earth, the Cambrian explosion in which a large variety of multicellular life forms came into being occurred considerable amounts of time after the formation of Earth, which suggests the possibility that special conditions were necessary for this to occur.
The well-known astronomer Carl Sagan speculated that all of the terms except for the lifetime of a civilization are relatively high, and the determining factor in whether there are large or small numbers of civilizations in the universe is the civilization lifetime, or in other words the ability of technological civilizations to avoid self-destruction. In Sagan's case, the Drake equation has been a strong motivating factor for his interest in environmental issues and his efforts to warn against the dangers of nuclear warfare. A lower bound on L can be estimated from the lifetime of our current civilization from the advent of radio astronomy in 1938 (dated from Grote Reber's parabolic dish radio telescope) to the current date. In 2004, this gives a lower bound on L of 66 years.
In an article in Scientific American, Michael Shermer estimated L as 420 years, based on compiling the durations of sixty historical civilizations. Using twenty-eight civilizations more recent than the Roman Empire he calculates a figure of 304 years for "modern" civilizations. Note, however, that the fall of most of these civilizations did not destroy their technology, and they were succeeded by later civilizations which carried on those technologies, so Shermer's estimates should be regarded as pessimistic.
Some computations of the Drake equation, given different assumptions:
R* = 10/year, fp = 0.5, ne = 2, fl = 1, fi = fc = 0.01, and L = 50 years N = 10 × 0.5 × 2 × 1 × 0.01 × 0.01 × 50 = 0.05
Alternatively, making some more optimistic assumptions, and assuming that 10% of civilisations become willing and able to communicate, and then spread through their local star systems for 100,000 years (a very short period in geologic time):
R* = 20/year, fp = 0.1, ne = 0.5, fl = 1, fi = 0.5, fc = 0.1, and L = 100,000 years N = 20 × 0.1 × 0.5 × 1 × 0.5 × 0.1 × 100000 = 5000
The remarkable thing about the Drake equation is that by plugging in apparently fairly plausible values for each of the parameters above, the resultant expectant value of N is generally often >> 1. However, this conflicts with the currently observed value of N = 1, namely ourselves. This conflict is often called the Fermi paradox. However those people who adhere to the premise of the Fermi Paradox believe that, due to a lack of evidence to the contrary, in all probability, humans (as a technologically advanced species) are effectively alone in at least our part of the Milky Way Galaxy. They further say that since we cannot yet determine the variables of the Drake Equation with any real confidence, we cannot determine the numbers of extraterrestrial civilizations based solely on this equation. We must therefore, they argue, rely on data collection - which is only now beginning to be collected in a significant manner. Only then can we even begin to presume what the values of each of the variables in the Drake equation are, they say.

(damn i sound smart lol)
(this is the possibility of ufo's mathematically.)

makes sense. AlthoughI had to take a few asprin through that read because damn was that a headache!
