He let the silence ferment before saying
'The bigger our planet is, the easier it is to be attacked by some celestial object. Case in point, an asteroid that nearly fall down to Earth a few weeks ago. Or that meteor that was shot down by one of our orbital destroyer. Or maybe some planets that went out of whack and suddenly come crashing down on our planet.'
He takes a breath before continuing
'Our planet gravitational pull is also changing'
'Fortunately, Jupiter had also enlarged itself. But, there is always a possibility that Jupiter would collapse into itself. If that is the case, then we would also be in its blast range.'
He did not mention the others, like the Sun, the other planets in their solar system that seems to compensate for their now sudden massive size…by also becoming large enough to make sure that the planets don't suddenly go veering of course.
That alone comes with another set of problem. The Sun could go supernova
