Was ‘Oumuamua ripped from an alien world?

Cosmic visitor ‘Oumuamua may have been ripped from an alien world

A close encounter with another star may have torn the cigar-shaped interstellar visitor ‘Oumuamua from its parent body, flinging it toward our solar system.

Quote

One of the weirdest objects ever discovered in our solar system — the alien space rock ‘Oumuamua — is still sparking debates more than two years after its discovery. And, most recently, the conversation has shifted to whether the cosmic visitor could be a fragment ripped from a larger world.

In 2017, the Pan-STARRS asteroid-hunting telescope in Hawaii spotted an object moving at a breathtaking pace of 54 miles (87 kilometers) per second. But, unlike most comets and asteroids before it, ‘Oumuamua would only approach our Sun once before continuing its journey through space. This made it the first known interstellar object to have passed through our solar system.

Aren't all asteroids just busted-off remnants from planets?  Or pieces of proto planets that never quite managed to form? 

Also leftovers from planetary formation and it is thought one is the core of a former planet.

One could just as well speculate it was von Neumann probe, with an equal paucity of evidence. There's billions of years of junk flying around the galaxy and beyond. We just happened to be looking when this rock chanced by.

Makes sense, given its velocity, which is sufficient to break free from our star's gravitational embrace.

That will be true of most, if not all, interstellar objects given that they have to have had sufficient velocity to break free from their own star's gravitation field.

"We showed that 'Oumuamua-like interstellar objects can be produced through extensive tidal fragmentation during close encounters of their parent bodies with their host stars, and then ejected into interstellar space," said study author Douglas N. C. Lin from the University of California.

In other words, long shard-like objects are produced in large numbers and cast out into the interstellar void when a planet or other large body strays too close to its star and is violently torn apart."

 

There is no proof at all for this theory, we only saw one elongated extrastellar object - ever-. Extraordinary theories  require extraordinary proof, which is not there.

Difficulties with the new scenario proposed for the creation of the object 'Oumuamua:

 A consolidation of broken-up debris, essentially a 'rubble pile' asteroid, seems unlikely to remain in a relatively fragile, highly elongated form while being whipped violently around its parent star.  The proposed scenario of this fragmented object becoming fused together in one piece requires it retain the elongated shape before and during this fusing process. It also appears to allow a very short time for this fusing to occur.

I think the idea is that a large rocky body is broken apart leaving smaller shards which are then jettisoned from the original star system. This would allow an object of Oumuamua's composition and shape to be created and then travel interstellar distances.

Yeah, it seems they look for every possible theory rather than admitting it might be of intelligent origin. It's as if denying the possibility is SOP in the world of science. Quite common, yet we've only glimpsed only one and frankly, we are only guessing as to what it really looked like.

Do I think it's from an intelligent source? I have no idea, but lets not bury the possibility everytime it's tabled.

Totally and utterly untrue.

The idea that it might be of intelligent origin WAS suggested and WAS investigated. Absolutely no evidence was found to support the hypothesis. When a hypothesis has no supporting evidence it can be disregarded.  They don't have to admit that it might be of intelligent origin because they have established that it almost certainly wasn't

And SETI assumes that ET is still using radio communication to call back home at the moment it flies past the sun. When they hear nothing is is assumed it was not ET. Probably ET uses something different to communicate (Photons, Gravity waves, Quantum entanglement) or other exotics that we do'n know of.

They might  send signals through what is known as 'bulk space' in M- Theory (String Theory), assuming it exists. This would, in effect, allow bypassing most of the distance of normal space. It is this distance that causes signals to weaken, and causes time delays between sending and receiving the signal.

Why would a probe of alien origin just sail through a solar system containing intelligent life and make no attempt to manoeuvre close to the planet that they live on?

You can add as much science fiction as you like, the fact remains that there is zero evidence for an artificial origin for 'Oumuamua and plenty of evidence for a natural origin.

If it looks like a rock of natural origin and acts like a rock of natural origin then there is a very good chance that it IS a rock of natural origin.
