Read this excerpt from A Black Hole is NOT a Hole. You might want to tell the folks back home about this. Ah, well, too bad. Once across the event horizon, you wouldn’t be able to get out any blogs or vlogs, email or phone calls, snail mail, smoke signals, messages in bottles, or signal flares to spread the news. Based on the topic of the excerpt, which question would be best for a reader to ask to check understanding? Which other types of communication may I use? Which folks back home should I tell about this journey? Why would I not be able to send communication home? Where does one cross over the event horizon?
