What is it? It did not follow the trajectory an asteroid could have. It did not emit any radio signals either to suggest aliens. It is the only interstellar object discovered in our solar system.

There are zero indications thus far that such a trajectory "could not be an asteroid". Read the fucking paper yourself https://lweb.cfa.harvard.edu/~loeb/LK1.pdf

It's awfully convenient for the government to publish and entertain these notions when it'd be convenient to get more people interested in sky watching and reporting objects they can't identify now that Russia and China are more of a concern.

But I guess instead of the obvious thing they've done repeatedly before just invent aliens and claim things are "impossible" about asteroid trajectories when your own fucking source says nothing of the sort.

That only works if the slingshot planet is moving with respect to the observer. Every body approaches and leaves a planet (or star) with the same velocity, from the reference frame of that planet, unless they do a powered flyby.
What was observed with Numanuma was specifically not a gravitational slingshot. The object approached and left the Sun at different speeds, from the Sun's frame.

The only explanation that satisfies these constraints is one that astronomers won't consider. Electric discharge machining from an electrically charged Sun would preferentially ionize the extremity without unbalancing the trajectory.

It is irrelevant. Do you think every hyperbolic trajectory is an alien coming to spy on us? Yes or no?

Here's the funny thing. Did you ever go check the "non-gravitational acceleration"? You're claiming it's aliens over an estimated non-gravitational acceleration of... 0.00000501 m/s^2.

Care to ponder for a second the question of.... "why?"

So what's more likely? The proposals centered on many mundane reasons we observe for non-gravitational acceleration... ooorrrr alien craft accelerates at the velocity a snail could outpace for no reason whatever? I'm not kidding by the way a snail is some orders of magnitude faster in acceleration.

Did you ever wonder why nobody reporting on it seemed to report the acceleration? Maybe, oh I don't know, it drives clicks and speculation from idiots who want little green men? And actually explaining to anyone how miniscule the acceleration is would be really fucking boring?

>> No.15295120

I'm not claiming it's aliens. I actually think it was hydrogen outgassing. The anomalous delta V was about 17m/s which is well within what hydrogen outgassing could do.
I'm merely trying to correct your brainless conceit about how "gravitational slingshots" work. You seem to think it goes
>fly by massive object
>gain speed
presumably without limit?

If that thing was an alien ship, one of them leaning his ass out an airlock and letting out a strong fart could have done that much.

>> No.15295137

>>15295120
>he anomalous delta V was about 17m/s
Summed. The resulting change in velocity can be SUMMED at closest approach to 17m/s. Its actual acceleration was incredibly small as I just told you. There are different estimates based on different distances such as 1 au, or 1.4 au, so on and so forth.
>I'm merely trying to correct your brainless conceit about how "gravitational slingshots" work. You seem to think it goes
That has to do with someone claiming the exit trajectory was somehow unique. >>15292747 not about its "non-gravitational acceleration".

Given how slow its acceleration actually was I think it's a distinct possibility doing so would've been faster.
