[DC] If Superman looks down at the ground and uses his heat vison, how far will the laser travel?

Is it gonna stop at one of the Earth's inner layers or will it go clean through to the other hemisphere?

It depends on how strong Superman wants it to go down honestly. There’s this popular moment in an animation (I forget which), but he used it against a mirror to shave his face so it never went through it or broke.
