Question Older book, guessing 1950s with word (I think) Ragnarok in title. Plot was 2 brothers taken by Valkyries to Asgard to fight in Ragnarok using modern science. One brother was sponsored by Loki.
Answer Perhaps you are thinking of the books by Nathan Archer or Micky Zucker Reichert, the short story by Jorge Luis Borges, or the magazine published by the Society of Fantasy and Science Fiction.
Google "ragnarok" and "Science fiction" and see what hits you get.
