In lecture four “Universe at Home” we look into our home galaxy, the Milky Way and discuss the features of creation we have mentioned in the earlier lectures. Our main focus here is the fractal spiral which resides at the centre of the galaxy as well as the ejections and accretion which take place at the centre without involving black-holes. From the standpoint of the gravitational theory a super-massive black hole is inevitable to exist at the centre. In this lecture we shall see what exists there instead of the black-hole.

The strong x-ray emissions from the galactic centre had been used as arguments behind the presence of the super-massive black-hole. We shall see how very massive stars are born from the process of ejections from the centre and contribute to the x-ray output one observes. The collisions of hot winds blowing from the helium stars may explain the x-ray phenomenon.The galactic centre also acts as a laboratory for  star-cluster formation involving the process of ejection. It gives a dramatic picture of ejection of molecular gases from the centre.  It is the closest realm where we can study how a micro-triskeion forms inside a mini-triskelion which in turn is embedded inside the universal wheel from where arms made of stars, dusts and gases are hurled out into space. We end this chapter with the discussion of dark galaxies which move around the neighbourhood of the Local Group of galaxies.
