It allows the sun to be relatively stable for the last 4.5 billion years.
(and hopefully for the next 5 billion.)
"While the star can produce energy, that keeps the star in balance - it keeps the star from collapsing. By the way, another outward force is the gas pressure, but that, by itself, is not enough to counteract the force of gravity in the case of a star."
Gravity and radiation are not really opposites. Gravity is a force that attracts objects with mass towards each other, while radiation refers to the emission of energy in the form of waves or particles. They are distinct phenomena that operate independently of each other in nature.
The source doesn't care how far you are from it, or whether you're even there, andthere's no relationship between that and the intensity of the radiation it gives off.However, the intensity of the radiation that you receivefrom it is inversely proportionalto the square of your distance from it ... same math as for gravity.
When the outward force due to fusion and radiation balances with the inward force of gravity, a star is said to be in a state of hydrostatic equilibrium. This balance between the forces maintains the star's stability and prevents it from collapsing or expanding uncontrollably.
The force of gravity between two objects is affected by their masses and the distance between their centers. The larger the masses of the objects, the greater the force of gravity, while increasing the distance between the objects decreases the force of gravity.

Yes, but so does internal pressures. (Which wouldn't exist if gravity wasn't present.)

No, gravity is a fundamental force that exists between objects with mass, causing attraction towards each other. Light emitted by the sun is a form of electromagnetic radiation and does not generate gravity.

I. E. Craig has written: 'Radiation, a function of gravity' -- subject(s): Radiation
Gravity effects anything that has mass, period. This includes electromagnetic radiation. Even light bends in space because of gravity.
When the outward force due to fusion and radiation balances with the inward force of gravity, a star is said to be in a state of hydrostatic equilibrium. This balance between the forces maintains the star's stability and prevents it from collapsing or expanding uncontrollably.
Light is a form of radiation. Radiation is an emanation of energy from a body, that can pass through a vacuum unaffected. it travels in a straight line, and is only slightly affected by gravity. A black hole obviously will, with its massive gravity well, affect all forms of light and radiation. Heat, light particles (photons) and radiation particles (alpha, beta, and gamma) are all forms of radiation, among other more exotic forms.
