    The main difference between non-black hole forming and black hole forming star is initial mass. Stars below a set mass will never supernova and will never become a black hole. Even stars that supernova aren't guaranteed to form a black hole; if the central mass left over isn't beyond a given mass(~2.2- 2.9 solar masses)*, a Neutron star will be the result instead.

    * this is the remaining mass, since the majority of the star's mass is blown off in the supernova, the initial star mass needs to be many times this. Given that a typical stellar black hole masses between 3-10 solar masses, it means only stars much, much more massive than our sun ever have the chance of forming a black hole.

    You slam nuclei together hard enough that they get close enough for the short range and attractive strong force to dominate the long range and repulsive electromagnetic force and you do it with nuclei that make a stable nucleus when combined or at least a nucleus that has a decay chain to a stable nucleus. In nature this only happens in significant quantities if you accumulate enough matter for its own weight to compress it a lot. Particle accelerators do it by accelerating ions electromagnetically but at the moment we still spend more energy on accelerating and containing the fuseable (fussile?) material than we get out of the fusion so it is a net energy drain not a net energy source until we make everything more efficient.
    You what?

    I can think of many answers…
    No protons no element.

    What type of reaction would allow for a mass great enough to produce a fusion star? On the elemental level?

    That's backwards. Larger masses allow fusion deeper into the periodic table. Not vice versa.

    Gravity. If enough hydrogen collects together through gravitational attraction, the weight of the outer layers produces a great enough pressure at the center to push the hydrogen nuclei close enough to initialize fusion.

    Could that happen close to our sun? In essence a fire lighting a candle?

    I ate a piece of bacon that had every element in it and it did nothing for me, but make me fatter than the skinny I am. Now I have a belly full of jello and pecks and arms made of nothing but muscle. This precludes the fact that I hope to be banned because I understand “everything” better than anyone else

    oh that's easy... the ignore button works wonders in situations like this...

    Hey I’m just trying to be a man of my word.

    what part of anything was I trying to confirm or deny?

    He's describing the formation of the Sun. The Sun can't light another star. Where would the fuel come from?

    No. Even within the Sun, fusion only occurs at the core, as it is only there that the temp and pressure is enough. By the time you get out to the surface, the temp has dropped to ~6000 degrees C, while at the core it is ~27,000,000 degrees.
    To use your analogy, you'd be trying to light a candle with a match held several yards away.

    But the core only has fusion because of the specific elements within it. If it was just hydrogen it would take much more pressure and heat than it has.

    Do heavier elements contain more quantum particles capable of fusion?
    And aren’t all fission able elements made from the process of fusion?

    Wrong. Fusion at the core of the sun can occur with H1 (the common isotope of Hydrogen) via the proton-proton chain, because the pressure and temp is high enough. No other elements are required.
    All man-made fusion reactions( such as those those in thermonuclear weapons), require H2 (deuterium) or H3(tritium), as they have less stringent requirements for fusion.

    I have no clue as to where you are getting your ideas from.

    best chance for success
    stellarator or tokamak?

    Without those other elements the heat would not be enough to produce fusion.

    the essence of anything determines what it will be. Not the sum of our scientific knowledge.

    Covering elements with stainless steel allows quantum particles to pass and interact with the elements within which are slowly reacting with the iron, creating hydrogen at the core which chains the fusion process till it is released as electrons from the steel shell….

    Stop. Just stop.
