Will Earth's magnetic reversal cause catastrophe?

When i read the title i thought why would the poles change?

I do believe in a slowly expanding earth, i am from the belief that there is a force in the core that produces matter slowly, but i have no idea whatsoever if that is true

that is just what i believe because landmasses used to fit together and the earth has after all this time not cooled down, so i think it is something perpetual, but then again i have no clue what it could be.

And for the same reason i believe the sun would have burned down a long time ago yet it did not, something in it is making elements, but there is nothing that suggests that there ever was a pole change, i don't think it is even possible, since it is perpetual, the planets that were gonna collide collided a long time ago. everything is stabilized.

Although there are galaxy's that are going to collide...
