Part 9/10:
The interesting premise raises a pivotal question: could Earth eventually become a black hole? Realistically, under these specific conditions where density remains unchanged, it is implausible. For black holes to form, Earth's density must increase, which would eventually lead the planet to collapse into a white dwarf star due to growing internal stresses, eventually surpassing the Chandrasekhar limit after about 1500 years if mass continues to increase accordingly.
