It's not likely that that chain could hold that much tension

The planets would freeze and life would die, and unless superman goes ftl which is itself non-scientific, the journey would take hundreds of years at least so yeah ain't nobody surviving that

>Is this possible in real life, scientifically speaking?

Assuming the chain, and superman, are strong enough there's still a couple of problems:
-I'm pretty sure the planet itself wouldn't be able to handle the ?tension? of having it's own weight be pulled on by a chain from such a small point. It'd most likely just break a hunk off - like trying to tow away a piece of spongecake. Superman would have to wrap a bunch of chains around each planet and toe them like a billiard net to evenly distribute the force.
-This one: >>17029952 Even assuming Superman is going super-duper fast, but still slow enough that the velocity ?g-force? doesn't smoosh everyone, there doesn't appear to be any source of heat. Everybody would freeze and die before he got anywhere - especially considering the vast hypothetical distance between a dying universe and a fresh fertile one.

Those planets would definitely freeze in the journey between galaxies. Even from star to star within the galaxy it would take several years to make the trip. These people would need deep underground heated bunkers sheltering many species to have any chance of preserving their ecosystem. As for the chain… lmao

>>17029927
Yes, that how our solar system got here.

>>17029927
If the planets are small enough, sure.

>>17029927
Superman needs fresh perky suns for his superpowers so no, scientifically speaking he would be weaker than a human around those dying worlds and not be able to breath the vacuum either

>>17029927
this best be bait

>>17029980
You're forgetting that the power of friendship is a viable substitute for the heat of a star.

What if we based science on the axiom that everything published in 1960s Superboy comics is true?
