This also assumes that the 7 quadrillion smaller spheres inside of the larger sphere have the same total surface area - and it's been too long since I've done any of that to know if it's true.
No, they don't. Surface area increases by the square of the radius, and the volume by the cube of the radius. A sphere with 7 quadrillion times the volume would only have 280 billion times the surface area,
