Question

What are effects of the strong gravitational forces found holding the mass of the Sun together?

Answer 1

Gravity is responsible for the Sun's stability and operation.

Explanation:

Gravity is always trying to collapse objects. A very important consequence of this for planets and stars is that it responsible for them having a roughly spherical shape. Gravity is kept in balance by pressure preventing further collapse. This leads to a stability called hydrostatic equilibrium.

Another consequence of gravitational forces holding the Sun together is that it results in high pressures and temperatures in the Sun's core. This enabled fusion reactions to start and be maintained. The Sun's gravity is held in balance by the outward pressure generated by fusion reactions.
