Media hyped black hole images will show a whole lot of nothing.  Look at the simulations put out by the research team showing what they expect to find, nothing, at least at the location of the black hole.   Which is just fine.  A black hole is a region of space time from which light cannot escape.  The escape velocity for their gravitational field exceeds the speed of light.  In relativistic terms their effect on space time is such that falling towards the center of the black hole is as inevitable as the flow of time in the forward direction. As such the base standard expectation of a black hole image is to see nothing.   

Neil deGrasse Tyson was accused by three women of various acts of sexual misconduct over time. NatGeo and Fox paid for into the sexual assault, harassment, and misconduct allegations made by Dr Katelyn N Allers (inappropriate touching under the clothes), Ashely Watson (sexual harassment ), and Tchiya Amet (acquaintance rape by drugging). 

Neil D. Tyson was investigated by Fox and Nat Geo for sexual misconduct, the investigation complete Cosmos and Star Talk will return to the air. This investigation would always have been of limited scope and shows at least he is no Harvey Weinstein or Bill Ayers. A completed investigation by Fox and Nat Geo is not a trial nor does it have to be.  The questions before a corporate investigator are not those that would be in front of a court of civil or criminal law.  Their question is, did Dr. Tyson do anything which could bring liability upon the company?  If not, then they are in the clear.

 

Physics does not explain everything especially why people who are trying to buck the mainstream all end up “looking alike”.  More likely this is a matter of broader socioeconomic conditions which limit the options of those who wish to exist outside of the mainstream of society.  Unless a hipster makes their own clothing from scratch all they can do is create new combinations of clothing worn by the majority.  The number of combinations being limited means that those who try to dress differently than the majority wind up dressing like one of a small number of possible combinations of clothes manufactured for the majority.
