We require more minerals!
Yeah, the ship created a spacewarp, and some of the debris was blown through the same warp.
How can you have a slipstream in vacuum?
The same way you can have an FTL drive. Whatever the drive did, caused ripples in spacetime that produced a similar effect on the rocks as it did on the spacecraft. Calling these ripples “slipstream” might, perhaps, be a reasonable analogy.
Then that would be a time field.

Wiki:
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. Science fiction writer Larry Niven has tongue-in-cheek theorized that, based on such abundance, Krypton was actually a Dyson sphere with a surface hundreds of times that of a mere planet. Silver Age Lex Luthor found a way to artificially synthesize it.
In the Silver Age, it was stated that Baby El’s ship crossed the light-years by opening a space-warp between the two star systems, and that said hyperlight tunnel had never closed. Periodically stuff from Krypton’s end would fall into the warp and come out in the Earth end.
Because if you’re going to send your son half way across the galaxy to be ‘safe’, there’s no way you want pieces of your home planet falling on his head, or a clear path for any other survivors to get there.
Asimov’s thiotimoline is an organic material, not a mineral. But I think it deserves mention.
It’s got a wiki article if you don’t want to read the full original report.
Also more elements!!
I knew someone would make that comment. I figured it would likely be you.
Apart from the fact that it’s fiction, and the space-warp thing was a somewhat late addition, Baby El’s starcraft was EXPERIMENTAL, and not ready for prime time. Jor-El and Lara only put the child in it because there was no time for further work. The planet was within moments of kabooming, after all.

That Marvin guy does not like planets.
Besides, wasn’t Krypton, in its original incarnation, a “counter-Earth” (i.e. orbiting the sun at the same distance as Earth, but on the opposite side of the sun)? In that case, a good chunk of planet’s debris ending up on Earth seems very plausible.
Never heard that. One of the sources of Superman’s powers is that the sunlight is different here on Earth than on Krypton. And keep in mind that kryptonite didn’t show up until the radio serials.
That was during the “Man of Tomorrow” era, where he was pretty much just a more advanced species of human, I think. They’ve gone far afield since then.
I don’t know about what they were thinking when kryptonite was introduced, but the “yellow sun” was, I thought a later redaction, too. Originally is was just something like “Krypton had higher surface gravity, so of course there were all stronger”.
Not in any version of the story I’ve ever heard of. Any chance of a cite?
I would like to point out that even in-universe, Corbomite was fictional. Kirk pulled it out of his ass to trick an alien.
Wiki claims the radio show.
