Supermassive Black Holes (2000)

BBC Horizon

A recently discovered bright, distant object appears to be two supermassive black holes orbiting each other, like those seen above in an artist's conception. The black hole duo, announced in March 2009, could be creating ripples in the fabric of space-time, according to Einstein's theory of general relativity.Source: National Geographic. Image courtesy P.

Supermassive Black Holes
BBC2 9.00pm Thursday 30th November 2000

A violent end for Earth? In June 2000, astronomers made an extraordinary discovery. One that promises to solve one of the biggest problems in cosmology - how and why galaxies are created. Incredibly, the answer involves the most weird, destructive and terrifying objects in the Universe - supermassive black holes. Scientists are beginning to believe that these forces of pure destruction actually help trigger the birth of galaxies and therefore are at the heart of the creation of stars, planets and all life.

Supermassive black holes are so extraordinary that until recently, many people doubted that they existed at all. The idea of giant black holes the size of the Solar System seemed more like science fiction that reality - such monsters would be so powerful that they could destroy the very fabric of the Universe. But in the last five years a series of discoveries has changed our understanding of supermassive black hol... (read more)

Although the modern physics does not understand how the
gravitation is transfered, it still has found out that
galaxies consist of some mystery substance that has this
drawing force.

The dark substance is different from the observed substance.
Yet it has the the same kind of drawing force as the
observed substance has.

No, there is no gravitation!

All the stars of the galaxies have arised from the black
holes of the giant centres of the galaxies. They expand
three-dimentionally, opening up energywaves that have the
nature of atoms. The stars expand and push themselves away
from the galaxy centre in a curved orbit in a same relation
as they expand.

That is to say that also the furthest stars are thrown away
from the centre of the galaxy. The same way as their speed
of movement around the galaxy centre lets us suppose. Only
this is not observed, because everything expands
three-dimentionally in same relation.
