Again do you understand what dynamic equilibrium is? We have awarded a Nobel prize for this, a star is powered by fusion which is maintained by gravitational collapse it collapses to the point where it achieved a hydrostatic equilibrium between the force of gravity and the outward pressure of the fusion reaction that wants to blow it up. If the fusion reaction overcomes gravity it expands until fusion stops, if gravity overcomes fusion it collapses again until another equilibrium is reached by either fusing heavier elements or through degeneracy pressure, if that cannot be stopped then we get a black hole. >The Sun cannot be powered by gravitational collapse, or it would have stopped shining long ago. The Sun isn't powered by gravitational collapse, it's fusion reaction is maintained by it, just like we must maintain a fusion reaction by having the right pressure to allow for proton fusion in the first place and countering the radiation pressure from the fusion reaction which is why we need to constantly supply the reaction with energy to maintain it. The fact that you still do not accept this is simply mind boggling, consider reading up on hydrostatic equilibrium and stellar nucleogenesis. "An interstellar cloud of gas will remain in hydrostatic equilibrium as long as the kinetic energy of the gas pressure is in balance with the potential energy of the internal gravitational force. Mathematically this is expressed using the virial theorem, which states that, to maintain equilibrium, the gravitational potential energy must equal twice the internal thermal energy." Ironically enough this is exactly with what you've tried to counter my initial post, gravity doesn't go away it is what is keeping the reaction going, if you turn off gravity the gas would cool down due to the expansion and all fusion reaction would stop, but as long as gravity is there the reaction will continue until there is no more fuel to fuse.
