Before 2013, there were a lot of UFOs, a disc here, a point of light there, and a picture with the truth.
But after 2013, this kind of thing has become much less, and most recently, in 2017, it was mentioned, and the word UFO has basically disappeared from people's eyes.
It became a memory of the past.
Why?
In fact, it is easy to understand that the current satellite technology is quite developed, and three or five satellites can be mobilized to observe a place anytime and anywhere.
In particular, low-orbit optical remote sensing satellites have to take pictures with a thumbs up, and even small locusts can be photographed.
There is nothing not to see
However, last year, in December of 2023, a news was reported, the Cairo News Channel, that Egypt's air defense system found an unidentified flying object, and then the system shot it down.
After this incident was exposed, UFO claims appeared.
It only lasted three or five days, and there was no news.
What about the follow-up?
You did say the beginning, and the follow-up is gone.
It's a bit embarrassing.
Let's talk about UFOs today, and by the way, refute the rumors.
UFO！
What is a UFO? Looking at English with Chinese logic, sometimes I am confused and curious.
In fact, there is a word in English called a flying object of unknown origin, and its English abbreviation is UFO.
Therefore, in English, any flying object of unknown origin is called a UFO.
It's just that for quite some time, UFOs and alien spacecraft have been linked, and when I talk about UFOs, the first reaction in my mind is aliens.
In fact, this is not what people intended.
The question arises, so are there aliens?
It's really hard to say.
If you talk about this from the perspective of probability, in the vast universe, planets like the earth are at least 1,000 if not 800, right?
For example, there are about 250 billion stars in the entire Milky Way, and there are as many as 700 stars in the observable universe.
How big is a 700 wall? Seven is followed by twenty-two zeros.
Of course, there are also scientists who say that the solar system is a very special existence in the entire universe.
How special is it?
For example, in other star systems, there are either three stars or two stars, and the solar system is very special in that it is one star.
Then there is the great retrograde phenomenon in the solar system, the big Jupiter looks very honest, but in fact it is the most dishonest, thinking about leaning towards the sun every day.
Although Saturn is smaller than Jupiter, it can rely on its own mass, coupled with the rope of gravity, to drag Jupiter backwards.
So in the solar system, Jupiter approaches the Sun and is dragged back at a certain distance.
There are many more strange things like this in the solar system.
But even if this is the case, if you make up the environmental conditions of the earth, no one will believe that there is no second.
After all, the magnitude of stars in the universe is an extremely terrifying number, and in terms of probability, there will be other life anyway.
Therefore, not only the public is interested in this issue, but scientists are also exploring the location of extraterrestrials and setting up problems.
As the research continues, a famous physical scientist and Nobel laureate Fermi has a problem when he is discussing aliens and their flying machines with others.
"Where are they?"
At first glance, this sentence has no beginning or end, but this is a very famous scientific topic in the scientific community, called the Fermi paradox.
What does that mean?
This paradox is based on the assumption that scientifically speaking, humans actually have a million years to push technology to the point where they can travel around the galaxy in spaceships.
Then the question arises, what about aliens who evolved a million years earlier than humans?
Have they reached Earth now?
If so, why haven't we seen any hints of aliens?
This leads to the paradox, since there are aliens, where are they on Earth? If there are no on Earth, is there no alien at all?
Nowadays, many scientists are trying to find aliens, and they all want to solve the scientific thesis of the Fermi paradox by finding extraterrestrial civilizations.
For this reason, some scientists have raised the question that extraterrestrial life may not have human intelligence.
This led to the later hypothesis of the difference of the earth, which was used to explain the Fermi paradox.
What is the Earth Difference Hypothesis?
The Earth Difference Hypothesis holds that complex life formation requires a combination of contingencies to emerge.
There are many of these contingencies, such as the presence of natural satellites such as the moon, habitable zones of galaxies, great retrogrades, lithospheres, atmospheres, plate movements, and so on.
Nowadays, many scientists accept the Fermi paradox, and when studying theories or models about extraterrestrial civilizations, they will cite the Fermi paradox, although the Fermi paradox is an unproven topic.
Tell me about a UFO.
Speaking of UFO incidents, there were also many in the last century.
For example, on February 24, 1942, the Battle of Los Angeles broke out in the United States.
When they heard about the battle of Los Angeles, many people first felt that this couldn't be a fight with aliens, right?
When it's all said and done, it's understood.
When it comes to this matter, you have to talk about the knowledge points first, otherwise it will be a bit of a headless feeling to just take one thing out and talk about it.
In other words, 1942 was still World War II, and the United States had already ended at this point in time.
The reason for the end is simple: on December 7, 1941, the Japanese attacked the U.S. naval base at Pearl Harbor in Hawaii.
The sneak attack was very successful, but it also made the United States very angry.
At the same time, a seed was planted in the hearts of the Americans, and Japan could carry out a sneak attack on the US mainland?
For this question, Americans are also nervous, afraid that such a thing will really happen.
On February 23, 1942, just over two months after the attack on Pearl Harbor, the Ellwood bombing took place.
What's going on?
A Japanese submarine, running to the vicinity of Santa Barbara in California, USA, carried out an attack.
However, the attack was too rushed to cause any real damage.
However, as soon as the incident happened, the Americans' idea that Japan could attack the US mainland became much worse.
Then, on February 24, 1942, a UFO invasion occurred in Los Angeles.
This point in time is quite compact.
So what happened on February 24, 1942?
First of all, at about seven o'clock in the afternoon, the air defense sirens sounded in Los Angeles, and the piercing air defense sirens sounded until ten o'clock in the evening.
People thought it was over, but in the early hours of the morning, before dawn, the air raid sirens went off again.
At the same time, the local lighting is also controlled, and electric lights, candles and other lighting tools are not allowed.
After all, at this point in time, technology is not too developed, and they will use the cover of night to carry out sneak attacks.
If there are no lights on the ground, no targets can be found in the dark air.
On this night, thousands of air raid supervisors did not close their eyes, and all stood at their posts and looked up at the sky.
At 3 o'clock in the morning, the 37th Coastal Artillery Brigade of the United States began firing anti-aircraft guns into the sky, firing more than 1,400 shells in total.
Intermittently, anti-aircraft artillery firing until four o'clock in the morning.
And the aircraft of the 4th Interception Command are also equipped and ready to take off.
The lighting control was not lifted until about half past seven the next day.
So what did the more than 1,400 shells do?
No, the Americans themselves were beaten, buildings and vehicles were accidentally hit, and five people died as a result of the shelling.
Of course, the personnel did not die from the shelling, three of them died because of the chaos caused by the shelling, which caused a car accident, and the other two had a heart attack because of the continuous bombardment.
At that time, it was suspected that Japanese planes flew here and carried out air strikes, which led to the Battle of Los Angeles.
As a result, after the end of World War II, the Japanese were arrested for questioning.
The Japanese shook their heads, indicating that they had not done it.
But at that time, the Americans could see clearly that there were flares and flashing lights in the sky over Los Angeles.
The Japanese don't admit it, what's going on?
Eventually, the flying machine that appeared in this incident was called a UFO, and then it was hooked up with aliens.
However, this statement has always been a folk statement in the United States, and the US government has never confirmed it.
So this incident became an event in the study of aliens and UFOs.
It wasn't until 1983 that a research institute in the United States that stored the historical archives of the U.S. Air Force revealed what was flying in the sky during the Battle of Los Angeles?
It turned out to be a weather balloon lost by the Americans.
Because people were very sensitive to the Japanese sneak attack at that time, they mistook the balloon for an air raid, which led to the later air defense alarm and artillery bombardment.
This can also explain why the aerial vehicles in the sky did not drop bombs after shelling for half a day.
But this statement obviously displeased UFO enthusiasts, after all, the U.S. government always says hot air balloons or high-altitude balloons to explain such similar things.
For example, the Roswell UFO crash in 1947 was also said by the U.S. government to be a balloon.
In fact, during the Cold War, the US Air Force also made a special research project, which was to study UFOs.
Research began in 1952 and ended in 1969.
The most interesting thing is that the United States collected about 12,000 reports of UFOs throughout the project.
In the end, it turned out that most of it was a natural phenomenon, and then a small part of it was a prank by some people, or it was just nonsense.
However, there are seven hundred and one of them, and no investigation has been made into any reason.
Now part of the information about this project has been released.
The most peculiar thing is that some of this part of the information has been altered, and it is obviously inconvenient to say some secrets.
As for the secret, maybe it's some flying machines under development?
This is unknown.
Speaking of which, let's sum it up!
Most UFOs, he's really UFOs, not spaceships.
The UFO shot down by the Egyptian air defense system this time is not sure to be a drone or something.
Otherwise, there would be no Fermi paradox, and the whole thesis would have been proven long ago.
