Where dose all that hydrogen come from ?
All the hydrogen in the universe was created after the ‘Big Bang’. The ‘Big Bang’ consisted of one huge explosion (so the theory goes). Soon after the big bang the energy started to condense to form matter. The easiest element, and most favourable in terms of energy, to form is hydrogen since it consists of a proton and electron only. It is estimated that 75% of the mass of the universe is hydrogen. This makes for a lot of hydrogen. The Sun is composed of hydrogen (about 74% of its mass), helium (about 25% of mass, 7% of volume), and trace quantities of other elements. The Sun powers itself by converting hydrogen into heavier element, and then fusing these heavier elements into yet heavier. This process stops at iron as it is not energy favouarble to fuse iron into heavier elements. Elements heavier than Iron are created during Supa Nova (exploding stars). The Sun’s current age, determined using computer models of stellar evolution is thought to be about 4.5 billion years. The Sun is a
Aside from the idiot who tries to talk about flaws in theories he doesn’t understand, your problem is that you are talking about fission (which is for heavy elements) and should be talking about fusion. In fusion, the tiny change in mass produces a huge amount of energy (E=MC^2) so the hydrogen is “used up” very slowly. The gravity the guy says makes the center of the sun impossible makes the center so condensed that his scenario won’t work. The fusion energy created drives the mass apart (when the fusion stops, the sun collapses) and makes it turbulant. And remember that helium is heavier than hydrogen, making his bouyancy arguement sludge. The same kind of thinking as you are using was done to “prove” that the Earth couldn’t be as old as said (so God created it) until it was worked out that radioactive elements in the core generate heat and make the age quite reasonable.
