The most well-known microquasar is Cygnus X-1. The first confirmed black hole. The microquasar V 4146 Sagittarii surprises researchers. That microquasar sends photons. That energy level is even 200 TeV. That means the microquasar V 4641 Sgr Gives those photons an energy level that is almost the same as distant quasars that form around supermassive black holes.  How does the stellar-mass black hole give those photons the same energy level as supermassive black holes? Microquasars form in binary star systems where a regular star orbits a black hole. The black hole pulls material inside it. And then. It can create similar relativistic jets as the distant quasars.  The V 4146 Sgr is the binary star system whe

The interaction between black holes and their environment is more complicated than people think. When a black hole pulls material inside it the energy level of the material rises to an extremely high level. Part of that material travels to the poles of the black hole and impacts together.  That thing causes very high power X- and gamma ray beams that are leaving from black holes or at least near that thing. When those radiation pikes hit the material cloud around the black hole it makes the material shine. That shine means that the plasma that forms the main part of the galaxy is sending radiation.  What is the difference between interstellar and interplanetary nebulas? One description is that there are heavier elements like silicon and iron in the interplanetary nebulas.  Interplanetary nebulas are the supernova remnants. And interstellar nebulas are mainly hydrogen and other lig

Image: NASA Gravity and the limits of Einstein's theory One thing what we must understand, when we are creating texts and thoughts about black holes and forms of material behind the event horizon is that we can write and talk almost everything we want about that phenomenon. We cannot visit inside that object, because we don't have a single one near us. And because we cannot get any observations behind the event horizon, we cannot deny or prove a thing, what happens behind that point. The observations are things that are proven or abandon theories. That is the thing, what we must realize when we are thinking about theories and scientific facts. Fact is the thing that gravity influences every object with the same way, and in the empty or vacuum chamber plume and bites, what are made of iron are dropping with the same speed. And why the light doesn't drop to Earth. That thing is so fast, that Earth has so minimum influence to light, that we just cannot meter that
