Oumuamua may be Alien Light Sail

A weird object named Oumuamua is of an exosolar origin as evident by its high velocity and trajectory as it sailed through our solar system. Oumuamua apparently isn't a comet, because Oumuamua seemingly lacks a comet tail. Furthermore, Oumuamua has a fixed rotation period that would not occur if it were propelled by the out gassing of any volatile. Oumuamua's elongated shape and high Albedo is unlike that of any known asteroids in our solar system. When Oumuamua passed by the Sun, solar radiation pressure apparently accelerated Oumuamua precisely as how a solar light sail measuring a few millimeters of thickness and few hundred meters length would have been accelerated by the Sun's radiation pressure. Oumuamua is estimated to be within the range of size and it has an elongated shape as would be expected of a light sail spacecraft following Oumuamua's motion and acceleration as it went by the Sun.

[1810.11490] Could Solar Radiation Pressure Explain 'Oumuamua's Peculiar Acceleration?

I would side with the experts on saying it's actually an inert comet. While it doesn't have a tail per se, they did notice there were still jets coming off the surface conducent with the characteristics of a comet.

If Oumuamua were a comet though, wouldn't its rotational period have changed from increased out gassing as it approached the Sun?

What we could be looking at is a comet's nucleus. Basically it's a worn-out comet that has for the greater part , run out of material.

There's a really good article with Scientific American that explains it.

If comets melt, why do they seem to last for long periods of time?

Could an interstellar-comet-nucleus-like body be seeded with water bears?

I don't get it....What does Mwah Mwah reveal?

That whoever named it was having a joke about little green men.

aliens do exist but they are angels or humans from other places all the time "now do this" figure out a code but don't read it just do it........... Can you decipher what my code means? if you can I will give you more wisdom in return.......by the way i know who Allen is but walkers from the walking dead? yea they represent death anew but depraved.....

that is close but eels might be it but there is a can a cheese involved and I do like to quote you so be warned that i may be extremely cheesy right now........by the way i'm here for another 2 minutes so better be quick about it and do that again about the eels.......lol

All joking aside I was serious when I said what I said in the first post but I don't know if you really believed it but i have a really good sense of nonsense so obviously what I said was nonsense but think about walkers on the walking dead being among us but not literally but figuratively and shoot off because i like this thread but by the way I don't troll but i do have a sense of humor and I do like posting here but no offense but I do this for a good reason..........not trolling by the way but contributing to the conversation.........

But at the end of nonsense is sense....someone said ‘there but for the grace of god go i’, but that sense might be figurative not literally by the way but for my sense of humor it could be but maybe not.
