getStaticPaths is a method used in Next.js to specify dynamic routes for pre-rendering. When you set fallback to false, it means that Next.js will only pre-render the paths that were returned by getStaticPaths. If a request is made for a path that was not returned by getStaticPaths, Next.js will return a 404 error.In other words, when fallback is set to false, Next.js will not generate any additional pages on the fly. This can make your application faster and more predictable, but it also means that you need to be sure to include all possible paths in getStaticPaths.
On the other hand, when fallback is set to true, Next.js will generate a page on the fly for any path that was not returned by getStaticPaths. This can be useful if you have a large number of dynamic paths and don't want to pre-generate all of them at build time. However, it can also make your application slower and less predictable, since new pages may be generated on the fly for each request.
