There's little or no real science involved. We already make materials that are all one molecule for all practical purposes (breaking them involves breaking bonds within molecules, not merely separating intact molecules) and while they are very strong by ordinary standards, those materials are nothing like GP hulls. The most detailed discussion of a GP hull ...

The answer is a major spoiler in and of itself and who the Engineers are/were is another spoiler

There is ample evidence that the Ringworld is very old (millions of years); the evidence includes, for example, the level of divergence of the humanoids populating the Ringworld from Earthly humanity. However, there is also evidence of decay that cannot have been going on for nearly that long. Louis cites two specific elements of the decay that seem to be ...

Because the intramolecular force (the force holding atoms in a molecule together) is typically far stronger than the intermolecular force (the force holding molecules in a substance together) - mostly because, in cases where it isn't, the atoms typically rearrange themselves via a chemical reaction until they are, or until there aren't any molecules left (...

I wrote to Niven and he kindly responded. The story never got written. It was just a bit of background.

Try the following sequence of novels (some are collections of short stories): Neutron Star (introduces many key ideas like Known Space, Outsider Hyperdrive, and the Puppeteers). World of Ptavv (reveals more about the ancient Slavers that ruled the Galaxy). Protector (the backstory of the Pak, which is crucial to many key points in Ringworld). Ringworld (...

A reaction drive is a weapon effective in proportion to it's efficiency. The in-universe origin can be traced back to the first contact between Humans and Kzin where (told in "The Warriors") and the subsequent Kzinti attempts to invade the solar system. Just now I'm not positive about where the phrase first appeared in text, but the Ringworld mention has ...

I am slightly hesitant about answering a question like this, as most answers are likely to be subjective unless we can find an interview from a movie industry insider who says that Larry Niven stories are hated - which is very unlikely even if it were true. I think that the problem is that Niven's stories are just not that easily adapted for the screen. I ...

Because the Pak didn't have it. Their technology was not that advanced, really, at least in Pssthpok's era. (If they built the Ringworld, some must have been more advanced, at one point.) At the time Pssthpok showed up in Sol System, humans had invented the ramscoop, but didn't have manned ones yet; on the other hand, Brennan considered Pssthpok's ship ...

The order of publication for the Ringworld prequels: Fleet of Worlds (2007) Juggler of Worlds (2008) Destroyer of Worlds (2009) Betrayer of Worlds (2010) Fate of Worlds (2012) Although the books may be enjoyed singly, they do have overlapping plots, characters, and locations - and a sense of continuity that probably makes the most sense in the above order.

The true nature of starseeds is only revealed a bit later, near the end of Juggler of Worlds.

Larry Niven wrote The Slaver Weapon. At the time, Roddenberry thought The Animated Series would essentially be Star Trek's last hurrah. He has said that he did it with Filmation because he thought it was the only chance he'd ever have to do another series. And they allowed some well known SF authors like Niven to come and work with them (as they did in ...

The key piece of information was the view from the map room the expedition discovered. The room displayed tapes from telescopes that offered an aerial view of the ringworld in the past. Fist-of-God mountain was not on the tapes, so the huge mountain must have appeared long after the ringworld was constructed and populated. There are no plate tectonics on ...

Although not from his "Known Space" future history, Niven's "Inconstant Moon" was made into an episode of The Outer Limits in 1996: http://www.imdb.com/title/tt0667911/

As I recall, there were a number of things. Roy was a descendant of Brennan and ultimately Brennan felt compelled to protect his blood line By allowing Roy to put on muscle mass, observe the Pak fleet and train in fighting Protectors; he was ensuring that there was the required transfer of knowledge in order to destroy the incoming Pak fleets in the event ...

To add to the other answers, in the "Fleet of Worlds" series of books it's revealed that the hulls contain generators (hidden within within the seemingly transparent structure) that reinforce the molecular bonds. It never really explains how, it's implied that it's stronger than normal single molecules, it's essentially magitec beyond that. From Juggler Of ...

The stasis field effectively slows the time rate inside the field -- in the first story where it appears, World of Ptavvs, by a large margin, and later (or in more advanced versions created in the deep past by other species) to effectively zero. The field generator for Lying Bastard was inside the GP hull, therefore protected from anything the hull would ...

Do you mean Brennan or Truesdale? Brennan's fate is described in Protector: What happens to Truesdale... is not covered in any of the Ringworld novels. (This could probably just be a comment, and given how old Protector is, probably doesn't need the spoiler markup, but just in case...)

We aren't really given the complete lifecycle of the Gw'oth. But the explanation given in the wiki is a bit of a misnomer. The time period mentioned for the Gw'oth going from discovering fire to mastering nuclear fusion was just under 200 Earth years. This time period would have been maybe three generations in human years, two if the humans lived an ...

As can be seen from the Wikipedia article, there is plenty of real stars among the stars mentioned in Known Space. While no doubt some of the further out ones are not real world stars, the closer ones tend to be spot on. Of course, there are no known planets at any of those stars that I'm aware of, and certainly none matching the descriptions. Known space ...

With respect to Niven, I don't think this is a valid claim. There's too much technology in Known Space for dumping planetary waste heat to be a serious problem. In one of the Peace Corben stories, "War and Peace", the kzin Buckminster suggests using transfer booths to take hot gases from the surface of Plateau and dump them into local space for ...

Who was Larry Niven? Larry Niven, one of the most prominent writers of the New Wave of Science Fiction in the 1960's and 70's, was very good at making stories self-contained while still part of a larger whole. Known Space was his first, best series of tales, and all of the stories in it are reasonably self-contained. While there are some story cycles ...

I highly recommend reading the first two Ringworld novels prior to beginning the Man-Kzin Wars series. Although Ringworld and Ringworld Engineers take place after the Man-Kzin wars, they introduce you to the interspecies conflict between Man and Kzin in such a way that the Man-Kzin Wars series becomes a "must read". (I also suggest reading the Ringworld ...

My money is on this question being answered in the final Fleet of Worlds novel, Fate of Worlds. As others have noted, the current Known Space books are contradictory on this; and it may be that Niven originally came up with the explanations simply as a means of limiting the FTL technology. Given these points, the best we can currently say is that there is ...

Having re-read the Borderland of Sol recently, I didn't get the impression that the 'hyperspace monsters' was meant to be an explanation of the generally observed effect of ships disappearing in gravity wells. It was just one possible explanation of the current disappearances which results from the brainstorming between Wu, Shaeffer and Austfaller. As the ...

The testimony of the many stories that involve Outsiders and the logical structure of their existence suggests what kinds of payment they would be interested in. If you read enough of the many Known Space stories you'll find that the Outsiders do quite a lot of business with warm species for as little contact as they have with them, so we have several ...

I can think of three reasons. Migration. On Earth, many species of migratory birds, turtles, fish and mammals return to rookeries and breeding grounds year after year. If you change the geography so that landmarks, food, water, ambient temperatures and other factors aren't what these animals expect, you will affect their development. Some species life ...

This is related in "Procrustes" from Crashlander from Beowulf Shaeffer's point of view, and Juggler of Worlds from Sigmund Ausfaller's. Wikipedia has a good synopsis:

It's been a while since I've read the book, but I think Brennan's concern would be that Roy might decide it's better for his descendants to do something different from what Brennan wants. for example, maybe he'd decide to kill Brennan and turn the ship back and try to save earth directly.
