Physicist Claims To Have Found Pieces of Alien Spacecraft
American physicist Avi Loeb has recovered 50 tiny spherical iron fragments from the bottom of the Pacific Ocean that he claims might be material from an alien spaceship.
Loeb connected his discovery with the passage of a fireball in January 2013. Sensors recorded the object as travelling at a faster speed than most meteors. It eventually broke up over the South Pacific Ocean near Papua New Guinea.
Loeb believes his claim is not unrealistic as Earth has already had at least one visitor from interstellar space—the comet Oumuamua. The object was observed in 2017 as it was leaving the Solar System, with a trajectory different from the orbits of planets and comets scientists are used to seeing.
In an article written in 2018, Loeb speculated that Oumuamua may not be natural in origin. He suggested we continue the search for interstellar debris to learn more about alien civilizations.
The metallic spheres he found in the ocean were each about 0.5 millimetres in diameter. They can be of extraterrestrial origin: several previous expeditions have recovered spheres from space from the seabed.
The most convincing evidence would be to determine the age of the spheres. If they were older than the Sun, it would confirm that they were from outside the Solar System.
However, more evidence would still be needed to prove aliens built the objects. Maybe the autograph of the alien engineer who built the spacecraft would be enough to prove Loeb's claims.
//New words//
spherical: round, like a ball
The Earth is not perfectly spherical.
speculate: to form an opinion about something without knowing all the details or facts
We can assume that the stone circles were used in some pagan ceremonies.
debris: pieces of wood, metal, building materials, etc., that are left after something has been destroyed
Debris from the aircraft was scattered over a large area.
determine: to discover the facts about something; to calculate something exactly
It is difficult to determine the exact cause of the illness.

//Discussions//
Q1
Do you think Loeb's discovery came from an alien spaceship? Why or why not?
-> Yes, I think so. Or rather, I want to think so.
I want to believe there were creatures other than humans, even though it was long ago.
However, we still do not understand everything, such as the structure and substances on the Earth.
So it might be possible that it's a mineral that I don't know about.
Q2
Do you think the fireball in January 2013 was an alien spaceship? Please explain.
-> Yes, I think so.
However, I suspect that extraterrestrials came flying in some form, rather than the spaceships we imagine in Star Wars and other space movies.
We must reconsider our humble feelings that we still do not know many things.
Q3
Do you believe the comet Oumuamua came from interstellar space? Please share your thoughts.
-> Yes, I would like to believe that.
Because I believe that the orbital movement is unusual and that there is a possibility that there are creatures other than humans.
Q4
Do you think we should continue to search for interstellar debris? Please explain.
-> Yes, I think so.
Let's continue to explore the universe to learn more about the Earth.
Of course, I can understand the opinion that it would be better to solve the global problems first because the cost is high.
However, it won't be long before the planet's problems are entirely solved.
More than that, I think there is a possibility that hints for solving the Earth's problems can be found in space development.
Q5
Do you think the metal spheres are older than the Sun? Why or why not?
-> Yes, I think so.
The universe existed before the solar system existed.
So I think it may be older than the Sun.
Q6
Would you, instead humans, discover or be discovered by aliens? Please support your answer.
-> I think humans should discover.
We need to actively search for extraterrestrial life, extraterrestrial minerals, and so on.
Our curiosity cannot be stopped.
Conversely, if aliens discover you first, you will be at a loss or confused about how to deal with it.
Instead, we need to take the initiative and ask the question.

Harvard professor Avi Loeb believes he's found fragments of alien technology
https://www.cbsnews.com/boston/news/avi-loeb-harvard-professor-alien-technology-fragments/
//Summary -Level C2//
Harvard professor Avi Loeb has retrieved potential alien technology fragments from a meteor in Papua New Guinea. The materials, confirmed to come from another solar system, include metallic spherules with unique colours and compositions. Loeb suggests they could be spacecraft or technological gadgets. Further research aims to determine their nature and explore materials beyond our solar system.
A)
CAMBRIDGE - Harvard professor Avi Loeb believes he may have found fragments of alien technology from a meteor that landed in Papua, New Guinea, in 2014.
Loeb and his team just brought the materials back to Harvard for analysis. The U.S. Space Command confirmed with almost near certainty, 99.999%, that the material came from another solar system. The government gave Loeb a 10 km (6.2 miles) radius of where it may have landed.
B)
"That is where the fireball occurred, and the government detected it from the Department of Defense. It's a huge area, the size of Boston, so we wanted to pin it down," said Loeb. "We figured the distance of the fireball based on the time delay between the blast wave's arrival, the explosion's boom, and the light that arrived quickly."
C)
Their calculations allowed them to chart the potential path of the meteor. Those calculations drove through the same projected 10 km range from the U.S. government. Loeb and his crew took a boat called the Silver Star out to the area. The ship took numerous passes along and around the meteor's projected path. Researchers combed the ocean floor by attaching a sledge full of magnets to their boat.
D)
"We found ten spherules. These are almost perfect spheres or metallic marbles. When you look at them through a microscope, they look very distinct from the background," explained Loeb, "They have colours of gold, blue, brown, and some of them resemble a miniature of the Earth."
An analysis of the composition showed that the spherules are made of 84% iron, 8% silicon, 4% magnesium, and 2% titanium, plus trace elements. They are sub-millimetres in size. The crew found 50 of them in total.
E)
"It has material strength that is tougher than all space rock seen before and catalogued by NASA," added Loeb, "We calculated its speed outside the solar system. It was 60 km per second, faster than 95% of all stars near the sun. The fact that it was made of materials tougher than even iron meteorites, and moving faster than 95% of all stars in the vicinity of the sun, suggested it could potentially be a spacecraft from another civilization or some technological gadget."
F)
He likens the situation to any of the Voyager spacecraft launched by NASA.
"They will exit the solar system in 10,000 years. Imagine them colliding with another planet far away, a billion years from now. They would appear as a meteor of a composition moving faster than usual," explained Loeb.
G)
The research and analysis are just beginning at Harvard. Loeb is trying to understand if the spherules are artificial or natural. If they are born, it will give the researchers insight into what materials exist outside our solar system. If it is fake, the questions begin.
"It will take us tens of thousands of years to exit our solar system with our current spacecraft to another star. This material spent that time arriving to us, but it's already here," smiled Loeb, "We just need to check our backyard to see if we have packages from an interstellar Amazon that takes billions of years for the travel."
H)
He still has more debris to research and hours of unwatched footage from the camera attached to their sledge. He believes there is a chance the spherules could be small breadcrumbs to a more significant find.
"They also help us pinpoint any big piece of the meteor we could find in a future expedition," detailed Loeb, "We hope to find a big piece of this object that survived the impact because then we can tell if it's a rock or technological gadget."
Why a Harvard professor thinks he may have found fragments of an alien spacecraft

After spending years studying the night skies for signs of extraterrestrial life, Harvard University astrophysicist Avi Loeb believes he has found proof of their existence at the bottom of the Pacific Ocean.
Professor Loeb has just completed a $1.5m expedition searching for signs of a mysterious meteor dubbed IM1 that crashed off the coast of Papua New Guinea in 2014 and is believed to have come from interstellar space.
The 61-year-old told The Independent he oversaw a team of deep-sea explorers who found 50 tiny spherules, or molten droplets, using a magnetic sledge dropped from the expedition vessel the Silver Star 2km underneath the ocean's surface.
