The availability of atomic clocks, together with the increasing accuracy of astronomical observations ( which meant that relativistic corrections were at least in the foreseeable future no longer going to be small enough to be neglected ), led to the eventual replacement of the ephemeris time standard by more refined time scales including terrestrial time and barycentric dynamical time, to which ET can be seen as an approximation.

In several accounts, it was explained that the explosion of the planet Krypton had opened a " dimensional warp " ( similar to a wormhole in modern theoretical physics ) which allowed the vehicle carrying the young Kal-El to reach Earth in a relatively brief time, and a large amount of planetary debris had also passed through this " warp " and emerged near Earth at virtually the same time, accounting for the seemingly improbable abundance of kryptonite material and its availability to Superman's enemies.
