... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

... In the currently favored cosmology, CDM, the formation of dark matter structures can be simply understood as interactions solely through gravitational forces: small dark matter haloes form first and then merge together to build up larger ones. ... It is believed that such a process could be the feedback from the Active Galactic Nucleus (AGN; a BH accreting matter and radiating with large luminosities, LAGN 109 - 1015 L ) onto the host galaxy. ...

. Some Fundamental Questions? . Last 20 years: understand the mechanics of the main structures found in the Universe. Next 20 years: understand the origin and formation of these structure. What are the seeds of structure? . How do stars form and how is their formation regulated? . What effects do Active Nuclei have in the evolution of galaxies? . When do the first galaxies appear? .
