There are more hiding supermassive black holes in the universe. Than we expected.

"By combining data from NASA’s IRAS and NuSTAR telescopes, scientists have uncovered more hidden supermassive black holes than earlier estimates suggested." (ScitechDaily, NASA Unveils a Hidden Universe of Supermassive Black Holes)

In all spiral galaxies is a supermassive back hole. The spiral structure can form only if there is some mass center. The most dominating black hole in the Milky Way is Sgr A*. That black hole forms the mass center that forms a spiral galaxy around it. The supermassive black hole is the monster, that creates a galaxy around it. 

The mass of those black holes is higher than the galaxy that we see. And that's why they will pull the whirl that we see as the beautiful spiral galaxy around them. Some galaxies like the Milky Way have more than one supermassive black hole inside them. And that tells about the cosmic collisions between galaxies.

The supermassive black hole sees the born of the galaxy. And it sees the end of the galaxy. When another galaxy or quasar travels to another galaxy and its supermassive black hole it can push and pull the material away from around the galaxy. The relativistic jet of the quasar pushes material from around them. 

It's possible. Supermassive black holes in galaxies or quasars pull almost all material from around them. In the case of galaxies like the Milky Way, the supermassive black hole pulls the entire galaxy inside it. But before that, the Andromeda galaxy impacts our galaxy. 

The supermassive black hole. That is in the cosmic bubble or very thin material area the black hole turns silent. Things like black hole acceleration disks form when a black hole pulls material inside it. 

The silent black hole forms a weak acceleration disk around it. And that makes it hard to see that thing. Also, bright objects near that black hole can cover even large supermassive black holes. 

So, if the supermassive-class black hole can hide in the universe. It's possible that also stellar- and theoretical sub-stellar mass black holes can turn silent. That means. Those black holes can be invisible to observers because they have so weak acceleration disks. Sometimes astronomers say that maybe Planet X is a black hole that lurks in our solar system. 

In some other models, the dark matter is explained as small black holes. Those black holes can form when material gets in the black hole's relativistic jets. Or when some supernova or kilonova sends its shockwave. That thing can push particles into a form called singularity. That means it's possible that. Black holes form other black holes. So, the small mass black holes can still form in the universe. When massive energy presses planets and other objects into a singularity.

Mythic ancient Egypt

Mythic ancient Egypt

There is one detail in ancient Egypt, and it is that all thing seems like some kind of project. That project started from the pharaoh Narmer, the mythic pharaoh of the First dynasty who ruled about 3100 BC, and then the project seems to end in the time Ptolemy, and the last pharaoh of Egypt was ruled in 44BC, and then all power turned to hands of Romans.

Because in that time were many pharaohs, who were called as Ptolemy, is the conclusion, that the power of that ruler lost the meaning, because they were not wanted to named differently. And the thing is that when the Greeks took Egypt under their control the state would seem to lose its shine and glory.

So the question is that did those Egyptians meant that their dynasty would be ended, and why they would do that? The thing is that after the Great pyramid the funerals of the pharaoh turned more practical, and when the pharaoh Amenhotep IV/ Akhnaten turned the Egyptian religion monotheistic caused that the powerful priests killed that man, but at the same time they lost something from their power.

Could the pyramid be older than we think?

Answer for that question is simply "yes", and the thing is that the pyramid might build in many sequences. There is a possibility that the place of the pyramids like the "Great Pyramid" of Giza has been some kind of pyramid before pharaoh Khufu started to the construction of the Great Pyramid during the 4th dynasty in c.2580-2560 BC. And when we are thinking a construction work, the building of that monument began in the year 2580 BC and continued 20 years, we must remember that those were the official years when the pyramid was constructed.

There is a possibility, that during the time of Khufu was the peacetime, and that pyramid was the project, what mission was to keep the army in work, that soldiers would not have the time to think too much, and that's why this pyramid is so huge. But there was an ancient lake below this pyramid. That thing is telling, that there could be some other purposes for the pyramid than acting just the grave of the pharaoh, and maybe one of the purposes was to offer the safe place for pharaohs or highest grade officials if they must hide for some reason.

When we are thinking that through the pyramid would set the tube, the capillary pull would cause that the structure will pull the water below it. And if the pharaoh can open and close this tube by using a similar system, what is used in the smoke pipes, that would create cloud above the pyramids. 

When we are looking at the size of the great pyramid, there is a possibility, that in this place has been buried pharaohs long before Khufu, and probably that place was somehow holy for the Egyptians before Khufu started to construct the Great Pyramid. When we are talking about the purpose of pyramids, those strange monuments might have many roles in Egyptian society. The thing is that sometimes there must be rebels also in ancient Egypt, and the pharaoh must hide angry people in somewhere.

And what would be better placed than the Great Pyramid of Giza? When we are thinking about the ancient Egyptians they might be many changes in their cultures and ceremonies during history. And the thing is that the role of the pharaoh has been changed many times from the First Dynasty to the time of Ptolemaic dynasty, the last of the rulers, who used the title of pharaoh.
