everything points towards it being a chinese spy balloon.

when it was moving erratically side to side over the ocean it is because it was still tethered to the sub that launched it.
then it raised in altitude very fast because it was released from the sub...
then when the jets got close it automatically destructed (popped) and shrunk to a small piece of rubber immediately, giving the illusion that it accelerated away instantly into the distance.

there was either more than one (highly likely because spy balloons have a high failure rate), or the multiple radar returns was because the balloon dropped its payload.

dark matter is almost 'not real', it BARELY interacts with anything smaller than galactic scale.

there is a chance we might be able to prove this theory if we made light years wide donut shaped piece of gold or lead and rotated it at 90%+ light speed and checked to see if a black hole appeared in the middle.

however that will never happen in our lifetime (or our species lifetime).

who decided that 'supermassive black holes' are the same thing as stellar mass black holes?

i personally believe that supermassive black holes are not a physical object or collection of collapsed stars and coalesced matter.
i think that a supermassive black hole is a currently unknown phenomenon, only present only at the exact center of a galaxy, where the huge disk of rotating mass around it causes matter to orbit an empty region of space like specks of dust in water draining from a sink.
if the stars in a galaxy disappear, then the central black hole does too..

i think that eventually an object in this reigion will exceed the speed of light at the exact point it crosses the 'event horizon', causing it to literally disappear from existence (a built in mechanism by god/the universe to avoid any violation of causality).

this explains why the size and mass of a black hole can be observed when the information of what it has consumed is supposed to be lost... the size/mass only depends on the surrounding galaxy, it also explains a few other things like the redshifting of light from objects approaching a black hole (they are going fast as fuck).
