It is due to pressure that the outer core is liquid, and even more pressure means that the inner core is solid. So no room for dragons.
You need TO GO STUDY GRAVITY !!!!!!!!!!! Hense the reason we don't all float away /.
Why does gravity mean that there could be a hollow Earth? You may have misread me, I didn't say the core of the planet would go into space, but that it would fill an empty space within it. As liquids do.
