De todas formas quitar toda la corteza terrestre yo creo que no influiría altamente en la variación de la gravedad. 15 km de densidad 3 g/cm3 son poco comparados a la atracción de los otros 6365 km de entre 5.5 y 9. Haciendo un cálculo rápido (a lo mejor está mal, que mis cálculos de masas están muy atascados) de M = volumen esfera hueca*densidad = 4/3*pi*(6380^3-6365^3) * 3000 kg/m3 sale del orden de 2.3E13 , bastante lejano del resto de la masa del orden de 5.9E24.

Ahora si alguien más docto que yo calcula ya cuanto variaría quitar toda la corteza terrestre... chapeau.
