>>12149567special relativity is a complete theory that has countless evidence for it. Maxwell equations are relativistic for fucks sake. Play with magnets and you'll experienced
the effects of special relativity.
General relativity has a few issues as a theory, but no known evidence against it. GR isn't local and relies on background (Mach's principle), which may present problems. The solutions are also prone to singularities (black holes, big bang) which you can't treat with GR itself.
