From previous threads I have understood that crossing the event horizon of a supermassive black hole is nothing very unusual for the falling observer locally. Usually in these considerations the falling observer has been thought as a "point" without much dimension. How about if Earth (and rest of the Solar System) crossed the event horizon of a very supermassive black hole? Moreover, let's assume that Earth approaches the event horizon very slowly so that it would take several days (in Earth citizens clocks) before Earth would be completely below the horizon. Would we notice anything unusual (except that the Sun is missing for some time, and so on)? Or would the crossing of EH be dramatic and catastrophic event on Earth, interfering Earth's rotation and blocking signals and travels from parts below EH to parts above EH?
