Oumuamua: scientist who suggested that strange spacestone might come from an extraterrestrial spacecraft

Harvard scientists suggesting a piece of space rock could actually be an extraterrestrial spacecraft that flies past Earth, saying that the strange visitor "does not look like something we've seen before".

Astronomer Avi Loeb started international intrigues when he co-authored a document that suggested that Oumuamua, which flew past the Earth last year, could have been sent by extraterrestrials to probe the Earth. The investigation explored the unexpected movement of the rock and suggested that it could be a "ray of light" that was deliberately sent by aliens to investigate the earth.

But even if the rock has a natural origin, it is incredibly strange, Professor Loeb said to the Today program. It has a strange shape, does not show the characteristics that are usually observed with comets and asteroids, and flies through space in a way that scientists would not expect, he said.

"The most intriguing thing is that it travels along a path that, in addition to the gravity of the sun, means an extra boost," he said. "There seems to be a different power."

It is this strange behavior that prompted Professor Loeb and a colleague to speculate that the rock could have been thrown out of an extraterrestrial civilization by a blast deep in space. They even suggested that the object could be a probe that was deliberately sent through space.

It makes the object fascinating for scientists, wherever it comes from, he said.

"It is the very first interstellar object that we discovered in the solar system and came close to the earth," he said. "And it's like having a guest for supper and you realize that from the other guests you have it comes from abroad and you can learn more about the culture in that country without paying the ticket to go there. to go."

In the end it will be very difficult to learn more about Oumuamua, because it has quickly disappeared from the solar system and disappeared from sight. He said he hoped we could have found out – we are currently lacking the technology to fly fast enough to do that, but we have to have so-called rockets within ten years.
