Data analyst suggests 15 reasons why aliens aren’t seen

Data analyst Yung Lin Ma offers fifteen reasons, some of which are news to us. He begins by observing,

There are approximately 1 billion stars that can produce an Earth-like environment. Earth’s environment does not necessarily have life, and this ratio is less than 1 in 10,000. The reasoning is that at least in our galaxy there should be 100,000 civilizations. So why haven’t we even seen a single civilization?

It is therefore an active question.

Of its fifteen reasons, here are three:

3. Alien life exists and has visited earth. It was a long time ago. Later the aliens left. If you’ve seen the movie – Interstellar should know that the flow of time is different for different people. Humans may think the ancient aliens are long gone, but the aliens are just gone.

Interstellar (2014):

The passage of time is a concept worth considering. If that’s the answer, we should eventually find artifacts, just like we do with humans who lived long ago.

4. In fact, there are already a lot of aliens around us, but we are not aware of it. Perhaps in the visions of extraterrestrial civilizations, human beings have very low life. We are unable to understand the existence of extraterrestrial life. Just like humans watch ants. Ants cannot understand the existence of human beings. The ants may have noticed the human beings, but they certainly cannot understand.

Not so sure about this one. We don’t need to understand what aliens are doing so much as we need to confirm their existence. It’s within our grasp, just as confirming the existence of humans is within the grasp of an ant. Everything else depends on the following.


7. We communicate differently with extraterrestrial civilizations. We use electromagnetic waves and light to communicate. Extraterrestrial civilizations can communicate with something we don’t understand. It is impossible to find each other if communication fails.

It is certainly possible. Recently, it has been suggested that aliens could use starlight (mainly photonics). We would have no idea that the apparent winking of the stars is a form of communication, certainly not until we have started using photonics ourselves. Likewise, aliens may never have considered using sound waves, which is how virtually all humans communicate in everyday life.

You can also enjoy these tales of why we don’t see aliens. All of this offers some thoughtful sci-fi potential while we wait …

1. What if aliens couldn’t afford to take risks with us?
This is the Dark Forest Hypothesis, which uses the title of one of the novels by famous Chinese science fiction author Liu Cixin. The Dark Forest Hypothesis assumes that we can use sociology to determine what alien intelligences might look like or want. But can we?

2.Do the aliens we never find obey Star Trek’s primary directive? The Directive is not to interfere in the evolution of extraterrestrial societies, even if you have good intentions. Hence the zoo hypothesis. Assuming the aliens exist, it might be as well, on the whole, if they want to leave us alone. They might want to “fix” us instead …

3.How can we be sure that we are not just a simulation of ET? A number of books and films are based on the planetarium hypothesis. Should we believe it? We make a decision based on the belief that logic and evidence together are reasonable guides to what is true. Logical possibility alone does not make an idea true.

4.Have intelligent machines destroyed the aliens who invented them? This is the Berserker hypothesis. A smart lethal weapon may well decide to dispense with its inventor and, lack moral guidance, destroy everything in sight. Extinction of a highly advanced civilization by its own lethal technology may be more likely than extinction by natural disaster. They could control nature.

5. Researchers: Aliens exist but they sleep … And we wake them up at our peril. The Aestivation hypothesis is that immensely powerful aliens are waiting in digitized form for the universe to cool down due to the heat emitted by their computers.

6. Maybe there are very few aliens out there… The Rare Earth hypothesis offers scientific reasons why life in the universe is scarce. Even though life is scarce in the universe, Earth may be particularly suited to space exploration, as suggested by the Preferred Planet Hypothesis.

7.Does science fiction suggest that we are in fact doomed? This is the implication of an influential theory, the Great Filter hypothesis, explaining why we never see aliens. Depending on how we read the Kardashev Scale, civilizations disappear somewhere between the current state and the advanced state necessary for intergalactic travel.

8. Aliens could actually be watching us. Using the methods we use to spot exoplanets. But if they’re technologically advanced, wouldn’t they be here now? The Hart-Tipler conjecture (they don’t exist) is, of course, very unpopular in science fiction. But let’s face it, if only to move on to more promising speculations.

9. Does the short window to find AND close? According to some scenarios (brief window assumption), we may have passed our expiration date for contacting aliens. Of course, here we are assuming a law of nature as to the duration of civilizations. Can anyone state this law? How is it derived?

10. What if we don’t see aliens because they haven’t evolved yet? From this point of view, not only did we emerge at a favorable time in the history of the universe, but we could end up suppressing them. The firstborn hypothesis (we got intelligence before aliens) aligns with the idea that humans are unique but sees this status as temporary.

  1. Aliens exist, but have evolved into virtual reality on a nanoscale. This is the Transcendence Hypothesis, the last in our series of sci-fi hypotheses as to why we don’t see aliens. From this point of view, after a Singularity, ETs become virtual intelligences, exploring interior space on an undetectable scale.

12. Does intelligent life in the universe live in the inner oceans of planets and moons? The oceanic planets hypothesis is that intelligent beings can thrive in the inner oceans of the moons of gas giant planets – or in exoplanets – but they are trapped there. If intelligent life forms are trapped in the inner oceans of rocky moons and planets, Earth is a special planet, much better suited for space exploration.

13. Is real-world space travel too intimidating for ET? This is the percolation hypothesis as to why we do not come into contact with extraterrestrials. They can’t overcome the laws of physics, and neither can we. If there is a purpose behind the universe, maybe the aliens and we weren’t meant to meet. It is worth considering, given the physical barriers.

14. Aurora’s hypothesis: ET could only risk rare contacts with us. Given the difficulties and risks of space travel, advanced-tech aliens may only have visited Earth for one in a million years, the researchers say. After centuries of modern science, we are now looking for fossil bacteria on Mars, not without risk. AND can be in the same position.
