Do Aliens Exist?
Since the mid-20th century, research aiming at finding extraterrestrial life has been ongoing, which has focused on the common question. Do aliens exist? Are aliens real? However, our understanding of the world still supports the idea of the possibility of alien life.
A Nasa Study Hopes that the Question will be Answered
In 1995, the first exoplanet was discovered by astrophysicists Michael Mayor and Didier Queloz. The vast, unintense world, called 51 Pegasi B, was proof of the planets surrounding sun-like stars outside our solar system. 51 it took Pegasi little more than four days to circle his star, which was previously thought to be so close to his host that the incredibly high temperatures and other effects could not be survived by any planet.
Do aliens exist? It is a familiar question, which the implications of numerous films, scientific fictive novels and other forms of media and literature have imagined and explored. Astronomers have spent a good deal of time trying to discover traces of simple forms of life in other parts of the universe, known as “bio signatures.” But could there be “techno signatures” detected from the earth if an alien planet had an intelligent life built up by a technological civilization?
Are there Aliens? Reasons that Could Exist but did not Contact us:
Hundreds of Planets that could Harbor Life have been Discovered
An exoplanet’s atmosphere can be measured using a technique called spectroscopy to determine whether it contains the same substances that appear in the earth’s atmosphere. Although this does not confirm that alien life exists, it does point out that it is possible.
There is Life in Places that we Once Thought were Impossible even on Earth
We found microbes that survived on earth where they were thought otherwise impossible. In trenches untouched by sunlight, life forms based on familiar DNA were deeply identified in the ocean. Maybe moons can support life too, for instance.
Although there are Intelligent Forms of Life, your Conditions may Make Contacting us Difficult
There is plenty of other important considerations to take into account for the question, do aliens exist? Notwithstanding 300 billion stars, multiple solar systems and 10 billion years of civilization in our galaxy. The life that exists on the earth is our only example of life that makes judgments on alien life. With that in mind, astronomer Maggie Aderin-Pocock believes that thinking out of the box is important to us. For instance, she suggests that planets close to the active stars can harbor life under the ground that makes it harder to identify.
As the Stars are so Far Away, A Message from Alien Life might Take Years to Reach us
Some stars are 25,000 light-years away in the middle of the Milky Way. It would take approximately 25,000 years for a message from this region to reach us, so even if there is alien life, there are obstacles in the vast distance involved.
Contact with Alien Life would Require it to be Present Simultaneously with us
While it is possibly possible that alien people tried to contact earth, this might always have happened before humans were present, which means that we are simply unaware.
We are not yet Able to Travel Long Distances and this can be the Case for any Alien Civilization
There can be no wide spaceship sending between the stars yet; the most we can do is to send radio waves at light speed. Stephen Hawking has been a supporter of breakthrough Star shot, a project that explores the option of sending objects to our solar system using solar sails.
If Aliens Exist, they may not be Willing to Visit Earth
Even if there are alien civilizations able to communicate with the earth, they might not be inclined to do this!
What do Aliens Look Like?
“Look at the amazing diversity of biotope that has all developed in the same planetary environment here on earth. It wouldn’t be done on the two branches, on the two legs, on the two eyes, with the story, on the nostril the two gender, the shrub, etc. Intelligence, however, demands a kind of mechanism for protecting a vital brain, a skull, etc. The body requires certain protective mechanisms for the vital brain.
“It must be a breeding system, but it can be budding, seeding, splitting, laying an egg—not necessarily living, warm-blooded birth. They would need some kind of sensory systems, eye analogs, ore, odor devices. But their “eyes” would not necessarily be ours had evolved to the peak of their sun. The confusion, are aliens real is difficult to finalized yet.
“What aliens appear in the real world depends on where they have evolved. An alien evolving in interrelated space would have very different needs than an alien evolving in a planet like the earth.” “ Gravity, ambient density and energy sources would determine the size and shape of the alien. Aliens like plants are improbable because photosynthesis does not encourage complex strategies of survival. The need to hunt for food promotes mobile life. If such a life has developed in a thick, horizontal atmosphere
“An octopus is a good example of earth’s advanced alien analog. Octopuses are quite intelligent (probably human) and live in a completely alien environment (compared with ours). The pressures it faces evolution had to find new solutions—pressures completely different from mammalian ones on earth.
“First a true alien has an endothermic bilateral symmetry with an excellent manipulation ability and is equipped with a hard brain container.
“Eyes? Naturally. You must see to construct culture. The calf’s eyes are better than we do, and at least several times the eye seems to have evolved separately. Our alien’s eyes can only look superficially like our own. A lens and an iris are nearly a must.”
“Nose? An alien needs to be able to respire. It needs to be symmetric.”
“Mouth? Must have food intake means. All big animals have certain ways of catching and swallowing food. Some chew, others do not—some chew.
“Legs? Of course. Most sure. Another locomotive method is relatively slow and relegated to blinded animals and holes.
“Fur? Hair? Feathers? Scales? Anything truly extraterrestrial? Anything that makes sense could be the skin cover. It is not so likely to be true feathers. Due to flight feathers, the brains are small. Scales are unlikely because the ectotherms are especially well-adapted,
“Head? It will probably occur if you define your head as a kidney enclosure both for the brain and for the eyes, nose, and mouth.
“Neck? Not necessarily at all. It is useful to swing your head but can be seen in other ways. It is an annoying place to catch big cats with their powerful mouths and strangle you.
“Arms? You need to manipulate things with something.
“Fingers? You must have a method for tightly picking up and twisting and turning small objects. Probably too few are two fingers.
Do aliens exist is still the question of most us. It may be a host of mind and body types, as the world is now full of a wide range of understandings and forms. It could be pretty odd.”
