Instead of defining the "birth" of a protostar, we can use the near-death of a red-giant. Betelguese is unique only because that baby's gonna blow soon. Since the nuclear fuel is basically exhausted, hydrogen expands (hence the size). I don't believe that gravity is the issue here, but the change in mass itself. Density grows in the center core, which in turns changes the "structure" of gravity surrounding the star and further. During the "super nova" event, the core collapses, creating a huge amount of energy outward which we can call an "escape velocity factor". Gravity is going the other way obviously because the small high-density mass is so great. We basically agree (scietific community in general) that sometimes we have a black-hole event or the mere onset of a neutron star spinning at ungodly speeds that has been determined to be a factor in influencing gravity itself. These events are (in my opinion) proof of gravity. It has to be. Light might be a factor, but not a necessary variable. Magnetic forces play a part as does gravity. There are other examples on the "proof" of gravity. Gravity/non-gravity issue is extremely complexed. Way too many variables that fit physics as we know them. There are I'll admit some factors that have been unexplained....I speak of Quantum Mechanics/Theories. Been reading up on that subject lately only because there have been singlarities concerning gravtity/light relationships. |
