What is Rendezvous with Rama about?
An object fifty kilometres long enters the Solar System, and it is unmistakably artificial: a sealed cylinder, spun for gravity, dark and silent. Commander Norton's crew have weeks to explore the interior — circular sea, crystalline cities, biological machines waking as the hidden sun warms — before Rama slingshots around the Sun and departs, indifferent to humanity. Clarke offers exploration as pure experience, with no antagonist and no explanations; the Ramans famously do everything in threes, and answer nothing. The 'big dumb object' story perfected at a stroke.
