The Harvard professor says an alien visited in 2017

When the first sign of intelligent life first visits us from space, it will not be a giant saucer spinning over New York. Presumably, it will be a waste of alien culture.

Avi Loeb, chairman of the Harvard division of astronomy, believes he has already found some of that debris.

Outside of January 26, in his next book, “Extraterrestrial: The First Sign of Intelligent Life Beyond Earth” (Houghton Mifflin Harcourt), the professor lays out a compelling case as an object that recently wandered into our solar system Really part of alien technology.

The object in question, 25 light-years away, headed toward our solar system in the direction of the nearest star Vega and stopped orbiting our solar system on September 6, 2017.

On September 9, his passage brought him closer to the sun. At the end of September, it exploded at a speed of about 58,900 miles per hour from the orbit of Venus, and then on Oct. 7 it went past the Earth’s ‘gas gas constellation and before moving on to blackness’. The book.

Panoramic Survey Telescope and Rapid Response System (Pen-Stars) by an observatory in Hawaii – the object with the highest definition telescope on Earth was first observed.

The space object object was called ‘omuamua’ (pronounced “oh mu ahu mu ah”), which is Hawaiian – roughly – “scout.”

Like space travelers, it was relatively small about 100 yards long, but it was a big deal in the scientific community.

For starters, it was the first international object to be discovered from within our solar system. Judging from the path of the Object object, the astronomers concluded that it was not bound by the Sun’s gravity – indicating that it was just passing through it.

No crisp photos could be taken, but astronomers were able to train their telescopes on object objects for 11 days, collecting rims of other data.

Initially, scientists thought it was a normal comet. But Lobeb said the assumption risks giving “acquaintances to define what we discover.”

“What if someone in the cave sees a cellphone?” He asked. “He’s seen rocks all his life, and he must have thought it was just a shiny rock.”

Lobeb soon opened his mind to another possibility: it was not a comet but a technology derived from an alien culture.

About A number of unusual properties of the object helped Loeb to draw this conclusion.

The first were the dimensions of ‘Omuamua.

Astronomers looked at the sun object in a way that reflected sunlight. Its brightness varies ten times every eight hours, indicating how long it takes to complete a complete rotation.

Scientists have concluded that a wide budget is at least five to ten times longer than its width – like the shape of a cigar.

It doesn’t look like the naturally occurring spaceship we’ve ever seen – or even close.

In his book, Loeb writes, “This will intensify the geometry of ‘Omuamua at least a few times in aspect ratio or its width – to its height, which we have seen so far than the most extreme asteroids or comets,” Loeb wrote in his book.

What’s more, ’Omuamua was unusually bright. It was at least ten times more reflective than a typical solar system [stony] Asteroid or comet, ”the author writes.

It compares its surface to a shiny metal.

But the discrepancy that really pushed Loeb towards his ET hypothesis was the way to move ‘Omuamua’.

“More pressure from the sun – it was the same thing that broke Lunt’s back,” he said.

Using physics, scientists can calculate which path an object should take and at what speed it travels due to the force of gravity through the sun. The pull of the sun will increase its speed as it approaches an object, then kick it out of the other side, only that object will slow down as it moves away.

Impressions are gained in a fluid, global, diffused way.  The length of the object is estimated to be ten to hundreds of meters, depending on the size of the football field.

But ‘Omuamua did not follow this calculated path. Loeb writes that this budget has in fact “slightly, but very statistically accelerated to a considerable extent”, as if it had moved away from the sun.

In other words, it was clearly pushed by force in addition to the gravity of the sun alone.

At first the explanation seemed simple. Comets show the same acceleration, as they heat up their surface as they get closer to the sun, once releasing static gases, which act like rocket engines.

That illuminated material, however, forms the comet’s distinctive tail. Scientists looked carefully for any traces of tail or gases or dust that could propel ‘Omuamua’ and come empty.

Loeb calculated that with these and other inconsistencies, ‘the probability that Omuamua was some random comet, it was around a quadrillion, which led him to his blockbuster hypothesis.

But what exactly was that?

One possibility, oddly enough, is that it can be found in the technology we already have on Earth.

‘Some people don’t want to discuss the possibility that there are other cultures.’

About 40,000 years ago, astronomer Johannes Kepler observed comet tails that looked like solar wind, and wondered if the same force could propel rocket ships into space where the same force pushed the wind.

It was a smart idea that scientists now use to develop light cells for probes. The thin, reflective sheeting is spread out in space to catch the particles flowing towards the sun by advancing the vessel through the empty void. Alternatively, a trip to Earth’s powerful lasers could be made to propel it faster.

Loeb, who is involved in a light sail project to send a small, unmanned craft to a nearby star, said that if we have thought of this idea of ​​the earth, then why can’t aliens happen?

He and one of his comrades broke down the numbers and imagined that ‘Omuamua was not really a cigar-shaped one but probably a one millimeter-thick disc with a sil-like proportion that would cause its unusual acceleration as it moved away from the sun.

According to its purpose, Loeb is not completely sure. He speculated that it could be the “space junk” that once served as a kind of space navigation buoy used by culture a long time ago.

“The only way to see [alien civilizations] Greedy said investigators have to find their trash like journalists.

Of course, not everyone in the scientific community agrees with his theory.

In July 2019, the International Space Science Organization’s Omuamua team published an article in Nature Astronomy that concluded, “We have no strong evidence to support an alien explanation for Omuamua.” ‘

Loeb admits that his theories have raised the eyebrows of astronomers, but he is skeptical of his findings. “Some people don’t want to discuss the possibility that there are other cultures.” “They believe we are special and unique. I think that’s the bias that should be let go. ”

Loeb said the suspects turn back to assign the ward project a natural origin and the explanation they have given to explain its bizarre properties is not to bha for verification.


For example, some scientists have suggested that ‘Omuamua’s acceleration is due to the hydrogen stationed on its surface turning to gas and running like a comet, and that hydrogen would be invisible to Earth’s infrared camera, that’s why we couldn’t find it. .

But Loeb and one of his colleagues published a paper showing that “the hydrogen iceberg passing through international space will evaporate before it reaches our solar system.”

Whatever the truth, the stakes are high.

The acceptance that the alien race has approached – even through its trash can – will trigger a more serious search for trash, causing us to wail over the moon and Mars, for example, debris that may have crashed thousands or millions of years ago. .

And if more evidence is found, we need to start building tools to help the Earth cope with external messages, such as space treaties and academic fields such as astro-linguistics economics and astro-economics.

But, perhaps most importantly, any further discoveries could redefine our place in the universe.

“It will put us in perspective,” Loeb said. “If we’re not alone, are we the smartest kids on the block? If there was a species that had killed itself by war or by changing the climate, we could get our act together and behave well. Instead, we are wasting a lot of resources and other negative things fighting each other on earth which is a big waste. ”

‘After the appearance of Omuamua, another endocrine object, known as 2i / borisov, was seen entering the solar system in 2019 through the Crimean telescope. But it turned out to be a simple old comet.

Until recently, our tools were not sensitive enough to select these types of visitors. But Loeb said the technology would soon make it possible to find more astronauts, and the only way to unravel the mystery of ‘Omuamua’ is if such an object object is found and further investigated with an investigation.

He said his book “should inspire people to collect more data on the next object budget that they find strange.”

“If we get another one and we take a photo and it looks like a light sail, I don’t think anyone will argue with it.”
