Hello, I am not a scientist. I'm just ordinary girl from a random city working as a psychologist. However I believe that there might be life on other planets.

If the process of life can start on earth, why can't the same process occur on any other planet? Life taking place on a planet is an extremely rare thing. That's why earth is the only planet that holds life in our entire solar system according to the research today.

But our galaxy is so huge! We still haven't discovered planets containing life. There are infinite galaxies and infinite planets in the universe. If the process of life can happen on earth, why can't the same process happen on any other planet?

I believe that somewhere out there on a strange planet of some unknown galaxy life does exist. We just haven't found it yet.

We ignore the planets that don't contain oxygen, water, etc the things that we need for our survival because we feel if there's no oxygen, there won't be any life. But what if we are looking at it all wrong? Maybe life there doesn't require oxygen. How's that possible? Take trees for example here on earth. They don't need oxygen. They give us oxygen!

I'm not trying to prove Nasa or other space companies wrong. They're truly awesome and they've got highly intelligent human beings and advanced technologies that are capable to do things we cannot even imagine! But I'm just saying this might also be possible. Let me know if you think we are not alone :)

To think otherwise would ludicrous that earth is the only planet capable of sustaining life and/or does contain life

I think there may already be some here...

Trees take in carbon dioxide.
A single molecule of carbon dioxide contains 2 oxygen atoms.

To be honest I did not believe in life on other planets... not until I arrived on Earth...
Well no, seriously, I'm 100% sure that we'll find life on other planets, even in the solar system. Many experiments 'proved' (no in reality they did not) that life tends to appear more or less spontaneously as soon as there are the conditions. ANd we have on earth life in (extremofile are they called?) places where it looks impossible to find it, ocean's floor, volcanoes... but maybe it's because it's Earth. On mars there may be conditions in some places. On Encelado and Europa too, under the ice there is liquid water, so let's go fishing there!
Another thing is evoluted forms of life (assuming we are evoluted, oh yes come on we are... aren't we?)
Another thing still is the time allocated, civilization may exist only for some few thousands of years before being hit by an asteroid or burned by a supernova... so if they want to visit us, they need to hurry uo between a cataclims and the next, come on with that spaceship...
This could be extremely rare, maybe even unique. that's why we should take responsiblity of keeping the planet in shape, no plan b I'm afraid... not for a while at least

The first life on Earth was anaerobic.

An anaerobic organism or anaerobe is any organism that does not require oxygen for growth. It may react negatively or even die if free oxygen is present. In contrast, an aerobic organism (aerobe) is an organism that requires an oxygenated environment.

There are still anaerobic organisms on Earth now.

Additionally, black smokers are the centers of entire ecosystems. Sunlight is nonexistent, so many organisms – such as archaea and extremophiles;– convert the heat, methane, and sulfur compounds provided by black smokers into energy through a process called chemosynthesis.

There has been some speculation of silicon based life in the Universe.
Silicon can grow into a number of lifelike structures, but its chemistry makes it unlikely that it could be the basis for alien life-forms. Indeed, carbon and silicon share many characteristics. ... The fact that silicon oxidizes to a solid is one basic reason as to why it cannot support life.

There's also extremophiles.
Three examples of extremophiles are Picrophilus torridus (a thermoacidophile adapted to hot, acidic conditions), Antarctic krill (a psychrophile), and the Pompeii worm (a thermophile).

The Universe may have xenobiology (or synthetic lifeforms).
Xenobiology is a subfield of synthetic biology, the study of synthesizing and manipulating biological devices and systems. The name "xenobiology" derives from the Greek word xenos, which means "stranger, alien". Xenobiology is a form of biology that is not familiar to science and is not found in nature.

Mankind does not know if life exists elsewhere in the Universe.
The only reference we have as yet is life originating on planet Earth.
However, Given the magnitude and diversity of the Universe, the possibility of extraterrestrial life is likely.

Extraterrestrial intelligent life may not be as prevalent but again, given the scope of the Universe it still may be fairly common.
There is the Drake equation.
The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy



If you plug in a conservative number it results in significant results.

The Galaxy is an extremely small scale compared to the Universe.


Number of stars within 50 000 light years = 200 billion

Compared to



* Number of superclusters within 1 billion light years = 100
* Number of galaxy groups within 1 billion light years = 240 000
* Number of large galaxies within 1 billion light years = 3 million
* Number of dwarf galaxies within 1 billion light years = 60 million
* Number of stars within 1 billion light years = 250,000 trillion

Compared to 14 billion Light Years (The Visible Universe)



* Number of superclusters in the visible universe = 10 million
* Number of galaxy groups in the visible universe = 25 billion
* Number of large galaxies in the visible universe = 350 billion
* Number of dwarf galaxies in the visible universe = 7 trillion
* Number of stars in the visible universe = 30 billion trillion (3x10²²)

There are a few factors which miust be conmsidered in the search for extraterrestrial life in the galaxy (and Universe).

The most important factor is distance/time.

The nearest star to the sun (Sol) is a mere 4.3 light years.
This means at the speed of light. It takes 1 year to get there (or here).
What we see, if we had resolutions, is 4.3 years in the past.
As we move away from that - everything takes longer. The more distant the star system the further back in time we see.

If we see a star which is 100 million light years away, we see it as it was 100 million years ago.
If something happened 20 million years ago which caused the destruction of that star, we wouldn't know it for 20 million years.

Space Shuttles moved at 17,500 miles per hour.
Light moves 186,000 miles per second.
It takes light 4.3 years to make it to the nearest star from the Sun (Proxima Centauri) at 186,000 miles every second.
Voyager 1 moves at 38,610 mph.

There's a lot of 'space' between star systems.
The quickest we could currently get to Proxima Centauri, using our fastest rockets, is 80,000 years.

i hope there introspection is a lot better than our own.....here intelligence

means nothing when it comes to ones mental health....good luck hunting....

Yeah, but not all life forms are intelligent.

It’s been a while, but I’ve read that all plants require oxygen, and not just in a CO2 molecule. During part of the year they take in CO2 and release O2, and during another part they will take in O2. Something like that. In any case, I’m not one that believes in the molecules to life type of evolution. Actually, I believe in devolution and entropy. The Drake Equation is bogus, because, at the very least, it doesn’t take in to account a minimum of 200 factors: the events of 200 amino acids accidentally linking up in the perfect order and correctly folding themselves into the simplest protein. Plug in a conservative number? They never plug in a number remotely conservative enough. Even if you can create a protein molecule in a lab, that’s not life, and it required the input of intelligence to make it anyway. Evolutionists also tend to fail to address the issue of irreducible complexity. And worst of all, they still haven’t shown where information comes from: and that is the most critical component of life. I remember there used to be a famous scientist named Hoyle, who commented, after studying the issue at length, that the probability of life accidentally propagating anywhere in the universe was considerably smaller than a tornado hitting a junk yard and accidentally assembling a shiny, new Boeing 747.
In other words, if there is any other life “out there”, than it must either have originated here or been intelligently designed by the same Supreme Being who created us.

Now, all of that being said, I believe completely in the existence of flying saucers and other UAVs flown by nonhuman entities, and that abduction events do happen. These things are so well documented now that one would have to obstinately refuse to see and admit them. However, I do not believe that these nonhuman entities come from “out there”. I believe that they are genetically engineered life forms, which is something that has been going on since Antidiluvian times. And, “As in the days of Noah, so shall it be at the coming of the Son of Man.”

My pet rock is interested in the rocks bought back from Mars.

Not a believer in life on other planets myself. Yes the universe is huge and growing....

I am more interested in the spiritual world that exists beyond us.
How about you?



.

Anyone who has ever been interested in science fiction understands there could be life forms in the Universe which have shed their physical bodies and evolved to be beings of pure energy. I'm not saying science fiction is fact.
What I'm saying is the idea of a being of pure energy (or spirit) is fairly common in science fiction. The idea is based on the life after death, spirit separate from body idea many religions teach. People find the idea comforting.

Given the immense age and expanse of the Universe, perhaps its possible?
The Universe is more than 14 billion years old. Whole civilizations could have existed and disappeared in that amount of time. Human civilization is a mere 10,000 years old but there may have been or may be civilizations which have exceeded 100 million years or more out there. As far (or further) removed from us as we are to amebae.

Since the speed of light is restricted as the Universe speed limit, a spiritual or energy being might have the ability to travel faster than light. Light speed can't be reached because matter breaks down but energy can and does exceed the speed of light.

Its possible an energy being so far advanced could have the ability to manipulate the fabric of space and time. The same abilities we apply to our gods and angels. They could make their own bodies to inhabit from atoms when they want one.
I mean, look at what human beings can do right now with the material world after 5,000 years of development.
Imagine how advanced a species could be if they had 100 million years of development.
It boggles the mind. They would know more about the Universe than we can even imagine.

Tom, you make me laugh. Neither space nor time, nor “space-time” is a fabric for the simple reason that space and time are not things in and of themselves. They are merely phenomenal effects of a thing in the same way that a shadow is a deprivation of light. They are what something (aether) does, not what something is.

Secondly, have you noticed that so-called scientists keep making the age of the universe older every time they encounter a problem with their theories? Sort of like how they invent a new particle every time one of their darling equations doesn’t balance. It’s a little too convenient. It seems to me that every time we learn that life is a little more complex and a little less likely to propagate by chance than we previously thought, the pop-physicist/bean-counter comes along and says, “That’s okay, because we just added another billion.” I suppose they believe that if they say a big enough number they will sufficiently boggle our minds into believing in anything. But the fact of the matter is, all their big numbers are unsupported by actual evidence, only by extrapolations based on the fallacious supposition of uniformitarianism.

In physics, spacetime is any mathematical model which fuses the three dimensions of space and the one dimension of time into a single four-dimensional manifold. Spacetime diagrams can be used to visualize relativistic effects, such as why different observers perceive differently where and when events occur.

Science changes constantly because learning is not stagnated and final. As new things are discovered/figured out, science changes.
Since mankind knows very little about things (still learning) nomenclature, laws and limits are constantly changing.

Much of what we know, can't be physically examined, manipulated or measure.
Part of the quest for understanding involves theorizing.
A scientific theory is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results.
In the scientific method, there is a clear distinction between facts, which can be observed and/or measured, and theories, which are scientists' explanations and interpretations of the facts. An important part of scientific theory includes statements that have observational consequences.

The scientific method involves careful observation, applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation. A method of research in which a problem is identified, relevant data is gathered, a hypothesis is formulated from this data, and the hypothesis is empirically tested.

Changes in scientific fact occur as we discover new things because science constantly reevaluates itself against new data and theories. Its an ongoing process which will never be complete until everything is known about everything, everywhere in all possible time frames. So yes, they do change their words and limits.

According to ancient and medieval science, aether, also spelled æther, aither, or ether and also called quintessence, is the material that fills the region of the universe above the terrestrial sphere.
In physics, aether theories propose the existence of a medium, a space-filling substance or field, thought to be necessary as a transmission medium for the propagation of electromagnetic or gravitational forces.
Luminiferous aether or ether ("luminiferous", meaning "light-bearing") was the postulated medium for the propagation of light. It was invoked to explain the ability of the apparently wave-based light to propagate through empty space (a vacuum), something that waves should not be able to do.
The theory of relativity didn't disprove aether, but it provided a simpler explanation that didn't require an absolute omnipresent medium for the motion of light.

There is a theory which allows for a type of aether. Its called Vacuum Energy or Zero Point Energy.
Vacuum energy is an underlying background energy that exists in space throughout the entire Universe. Its behavior is codified in Heisenberg's energy–time uncertainty principle.
Zero-point energy is the lowest possible energy that a quantum mechanical system may have. Unlike in classical mechanics, quantum systems constantly fluctuate in their lowest energy state as described by the Heisenberg uncertainty principle.
A personal idea of mine which I rather enjoy musing over:

In the aether of space voids vacuum energy gathers into a point and coalesces to form particles of matter/antimatter. Matter and antimatter which come into contact with each other convert back to energy. However, not all matter or antimatter actually meet. This results in particles of matter and particles of antimatter being created where nothing was before.
It could account for how matter became dominate in the early Universe.
We (mankind) knows matter is composed of energy. Its the basis for nuclear reactions. Slam certain elements together with enough force and that collision yields extreme energy. Think atomic bomb. Stars do it naturally.
If you flip it around, energy should form matter if it condenses or gathers at a point. We split the atom to get energy, condensing energy should result in matter. It can't be done but I find it fun to think about.
If there is any validity to this idea, it would explain aether's role in the Universe. A low level field of energy which permeates the entire Universe.
Basically, matter is condensed aether.

MIGHT EXIST? Ya think???????

They are aware of the possibility of alien life, it's just our ability to view said life is extremely limited. Given the amount of planets in our current solar system/galaxy that provide the correct resources to host life are extremely low. There are still probably 73 million planets that can host human/ alien life but our scientist can only view 3-4. One of those planets was only found just recently. Not to mention the closest planet that has the ability to host life is so far away that our telescopes are viewing it millions of years in that planets past. As we do not have a device that can view these planets in there current time. Just as if you were on one of these planets with a telescope powerful enough to view earth, you would see any movement because you're viewing Earth 12 million years ago. One of the reasons we know this is because of when we were trying to measure the speed of light by shining a lazer down a pipe. You'd need one clock at the beginning of the pipe to tell when light entered the tunnel and a clock at the end of the pipe in sync with the clock at the beginning to stop when the light passes through the senor to measure the time. Their first idea was to have both of the clocks at the beginning and when the first clock starts the second clock rides along a rail system to the end of the pipe to catch the light with it's sensor to stop the timer. Their issues were that the clock on a rail wouldn't be able to keep up with the light and even if it could although the clocks were synced at the start of the pipe, when the clock on a rail would reach the end of the the pipe, the clocks wouldn't be in sync anymore. This observation of time multiplied by the distance between planets make it extremely hard to view other planets in their current time zone making it more complicated to view alien life.

The only aliens that exist are the illegal ones...NOT from other planets but other countries
