But the key idea stands: an inventor who invents something rare and non-obvious should be rewarded, supported, and encouraged to invent again. Or not?
Also it seems that prooving inventor capacity in this way is better than IQ test, suggested in the text.
There are lot's of apps, most of them work just fine, which is quite inspiring.
the accretion disks are commonly seen around binaries consisting of a stellar mass black hole and a regular star. stars feeds the disk in this case.
another possibility is to have a supermassive back hole in the galaxy center, which feeds on the surrounding gas, making much larger and slowed disk.
what has never been seen before a stellar mass black hole (or pair of black holes) feeding on the interstellar medium. This should happen of course, but the expected luminosity is way below anything detectable.
binary black hole, i.e. a system without any addition mass to accrete, would have to be in some very unusually dense medium, and the medium would need to be disrupted by merger.
interestingly, such medium can occur around another back hole - a supermassive one.
Does anyone else do this thing when they work 90% of the time remotely and sometimes travel for a day meeting? This addresses some of the issues discussed.
This can also work for informal communication, to a degree.
Physics/Astrophysics/Cosmology: Dark Matter and Dark Energy - are clearly observed, no satisfactory explanation exists.
Astrophysics (and Science in general?): very knowledgable specialized domain experts have issues learning from each other: too many different concepts, relations, methods. Even if universe is shared, representations are not easy to map on it at once. Astrophysics is especially bad in this.
