I'm coming up with a science fiction world for an assignment.
Would it be possible for a planet like Earth to be eaten by a giant alien creature that moves through space at a relatively slow speed and still remain somewhat intact after impact with the back of creatures stomach (assuming the creatures insides is almost like a tunnel). Most research proves that any large impact with Earth would be cataclysmic, I'm just curious that if the speed of which the impact occurs, could it potentially be survivable if the people on this planet had time to build bunkers and technologies that could help them withstand a certain amount of the impact or other destructive results of the incident?
Also would a creature of the size required to eat a planet be able to exist?
It's very far fetched and unbelievable, but I'm just looking for some way of backing it up logically so it's not completely ridiculous. If that's possible.
