1. The strange behavior of 31 Atlas object in recent days is due to the ejection of metal alloys - Nickel - and such can only be industrial created....Is 31 Atlas losing just mere compounds created from its original chemical and molecular make, during its journey across space, or are such ejaculations a form of waste debris from unknown sentient life on board?
One thing to bear in mind is that we Humans are carbon based lifeforms, made up of complex molecules but with the chemical carbon being the main source, but such does not means that it is the only molecules that are capable of sentient life, as Silicon had been discovered with capabilities to sustain life as silicon can tolerate high temperature environments such as found in other planets.
Thus they may be other form of chemical and molecular structured sentient lifeforms that our current stage of advancement in Science and physics may not be aware of.
2.However, there is no need to panic as that object is of a far distance from planet Earth - 1.5 times the distance between the Sun and planet Earth, and with its trajectory, perhaps influenced by our Solar System gravity pull, will just simply swing out into far space with the kind of speed that its travelling, the way many strange comets had done before...
3.The only time of concern is WHEN the object slows down, and due to the same gravity pull, will obit our Solar System......although it is highly unlikely as it had shown no change in its speed and course, travelling at 200,000km/hr.
At such speeds, to maintain an orbit here in the solar system, it will need much power to power down safely, even manually, which will take months on a gradually reduced speed in orbit. which will be evident to observers and space based instruments, including the still existing Hubble Telescope orbiting Earth.
Example:-
If a Human drives a car at 200km/hr, and then suddenly brakes, the car with good brakes such as Brembo, the car will stop within seconds. However, the driver and passengers in the car will be FLUNG out of the car as Newton's 1st Law on Inertia Physics determines such.
Therefore, just think what will happen if an object travels at 200,000km/hr and suddenly stops?
