During Man of Steel, we saw the World Engine pulsating with some gravity beam between both ends. I'm of the opinion that this reasoning is totally bat shit insane as we saw the ground in both Metropolis and when Superman was standing and there was no hole on either end at all, not even a small crater but flat dirt: (please log in to view the image)(please log in to view the image)
Gravitational forces act through intervening matter in the real world after all and this is fictional Kryptonian tech where even a black hole doesn't act like a real black hole.
I think it could have potentially ran through the Earth, but didn't thanks to Superman stopping it in time.
Those beams were probably meant to change the density of the Earth to increase its gravity. Meh, whatever, it's one of those feats that people will never agree upon.
As there is no hole on either side, it's obvious that the beams didn't physically dig through the Earth...not that it'd need to, what with it being gravity based.

I don't know why some of you are going on about being right and winning. Rob and Impediment were in on this gag because I PMed them. Silent and Rao PMed me and figured I changed the post. I highly doubt anybody thought Quan made the post, but simply played along just for the lulz.

No it wasn't a hole. It's not like it was a drill or anything. It was delivering a "pulse" connecting to the ship on the other side of the planet, creating havok with gravity.

one end (the end Superman destroyed) was pumping energy into the core, the other end (the end in Metropolis) is where the gravity pulse was. There was no hole being drilled.
It didn't drill a hole. It was sending some sort of energy pulse through the entire planet, which Superman powered himself through, despite his powers being weakened.
So in short, it's really a hard feat to qualify. We have no idea how strong it was exactly, thus we don't know how good a feat Superman powering through it is.
How much power would it take to send a (gravity?) pulse through the entire planet? But yeah, there is no "Oh, it's an 8.8 level feat" clear answer, but it seems very high.
The spaceship over Metropolis has actual gravitational destructive powers shown, as it is flattening cars and what not. There's nothing from the World engine side though that shows just how strong it's pulse is.
