The blankets were as invulnerable as the rest of him and Jor-El knew that if the ship made it off Krypton and away from Rao that they and the ships interiors would provide ample protection.
Yeah, it would best to just create an Einstein stand-in if that angle were to be used.
Hate everything about the birthing matrix, etc. Pure garbage IMO and glad it was retconned away. Hate the aura idea, it's lame. I much prefer the idea that Krypton's gravity and environment was so insanely harsh that they evolved to withstand it and away from there and from the red sun that Kryptonians are near-indestructible.
I'm neutral on Superboy, although I actually like the character a lot, but I don't feel it's essential.
Of course you do. You're a 1930's kind of fan. I'm not. I've been with the character since the late 50's and I've been a science fiction fan just as long.
There is absolutely no way anyone can convince me that you can slap a baby into the cockpit of a rocket with a few blankets, send him on a multiple light-year journey, and have him arrive as anything other than a dehydrated, starved corpse. As to the Kryptonians being near-indestructible - I'm a fan of Maggin's book, too... but there are problems with that concept as well. Those alien 'astronauts' would have died. There wouldn't have been a Kryptonian race. For arguments sake, let's say they didn't die and went on to breed a race of superbeings as Elliot stated... the death of the planet would have been an inconvenience for them and not the end of their civilization. They would have just gone indoors, shut the windows, and turned on their environmental systems. Supes can withstand amazing explosions... this would just been more of the same.
I do not find the aura lame. In fact, I find it a much more logical approach to explaining Superman's invulnerability. It certainly wins hands-down over generational built-up tolerance to heavy gravity. Again... the first generation wouldn't have survived to birth a second.
And, let me just add one more cord of wood to that fire... baby clark would destroy everything he touches as he would have no understanding of his own strength. The Kents would never have been able to raise him. A hug from a baby who doesn't know his own phenomimal strength would be fatal.
The aura, the charging over his early childhood years... they all make logical sense. Baby Clark couldn't start out superpowered. Not in a semi-realistic world.
There is also absolutely no way anyone can convince me that cloth (which is just dead plant fibers or extruded oil byproduct) can somehow develop superpowers under a yellow sun ... or be so powerful to begin with that it has the invulnerabilities that Supes costume has exhibited over the years. If it were that strong - the ship would have been made out of it.
As for all the other questions about the suit and the blankets, in the classic traditional canon, the blankets and the costume stretched and were as indestructible as Superman himself, the boots, belt and the lenses of his glasses were made from the remains of the rocket's interior. That is how he can use his vision powers without melting his glasses as Clark.
Kal-L designed his own costume and created the materials it was made from in the Golden Age, and I assume the lenses of his glasses as well.
The blanket explanation is by far the most iconic, imo.
Iconic - yes - but only for those of us familiar with the comics. For the general public - they wouldn't care if the suit came out of a box of cornflakes. I think it's one of those things we can let go of.
Keep in mind that I grew up with the character, too. Superman was the first comic I ever read and it was late 50's - early sixties. I had all the reprints from the 50's and a lot of reprints from before that. I'm not speaking as someone who's only exposure is Byrne. I grew up reading Heinlien, Asimov, Sturgeon, Clark, and host of others. I want Superman to at least attempt to fit into a world that makes sense. I totallly appreciate what Byrne did with the mythos. He tried to make his explanations believable for a generation too aware of science to believe you could slap a baby into a rocket with a few blankets and shuttle him off to Earth.
