DC’sSupermanis well - get laid throughout mirthful circles as the Last Son of Krypton , the lone subsister of his homeworld and his race . While other Kryptonians have been stick in throughout the DC persistence ( especially Superman ’s cousin Supergirl ) , Superman prevail the title as the last survivor for many yr . However , Krypton is often depicted as a highly - advanced society in almost every continuity - and in almost every continuity , the Kryptonians had mastered space travel . With that in mind , why was Superman the only survivor ?
In the modern old age of comics , a terrible warfare had engulfed Krypton and reshaped the wandering civilisation into a cold and isolated society . The scientist Jor - El , Superman ’s beginner , finally come upon life-threatening radioactivity building in the planet ’s core , andbegged the Kryptonian councilto provide the planet - but the stanchly isolationist council had forbidden space locomotion , and did n’t think Jor - El in any pillowcase . But even when Krypton ’s leaders realized Jor - El was right-hand , theystilldidn’t evacuate . Perhaps the rulers would rather die than break tradition … or perhaps there was another obstacle they trust could not be overcome .

A Kessler Syndrome , theorized by NASA scientist Donald Kessler , is a worst - showcase scenario that efficaciously dooms a population of a satellite to stay on aver satellite for decades , if not 100 . junk from satellites , rocket fairings and give up putz and equipment is quite unmanageable to trail ( and when one considered just how small some debris can be , almost insufferable ) , and despite the vastness of space around a planet , the likelihood of abandoned satellites colliding step-up with every launch . A societyas pull ahead as that of Kryptonwould surely have C if not grand of orbiting satellites … and as per the Kessler Syndrome hypothesis , one collision could head to another until navigating a ballistic capsule beyond cranial orbit would be akin to a ship passing a dense minefield .
This is why Superman ’s rocket left the planet - it was the only one thatcould . As a craft that could only hold one resident , it would be modest enough to navigate the Kessler field . This could also be another reason why Jor - El was ridiculed by the scientific community of Krypton ; the council would have call back travel through a compact dust field only impossible with massive excreting ships . This is also , tragically , why Superman ’s parent could not accompany their childto Earth .
For all the pseudoscience that comic Christian Bible present their lecturer , every now and then a plot of land maturation is based on an actual scientific theory . A potential Kessler Syndrome is a very actual terror - one that Earth could face quite soon if the accumulation of space dust in orbit is n’t stanch . Superman may have been Krypton ’s only survivorbecause the ruling body of the planet failed to heed to reasonableness , but our own planet still has a fighting chance .
