| Posted: 21 Dec 2019 12:50 PM PST We have been able to teach chimpanzees, gorillas and other apes so they can communicate with us, however it seems these experiments have been with isolated animals. I was therefore wondering what would happen if we for example took two newborn chimpanzees and taught them sign language, that would be the only language they know of then, right? They would communicate with both each other and humans through sign language (and probably instinctive sounds and gestures). If they then get offspring, would they then learn sign language from their parents? If so, does this mean we over time could generate generation after generation with the ability to have basic communication with humans through sign language? [link] [comments]  |

| Posted: 21 Dec 2019 10:37 AM PST Such a long rod would have an astronomic mass, that seemingly would be impossible to move with human-accessible forces. However, as the movement would take a very long time (50 000 years according to this interesting take by /u/chrisbaird of another question). So according to my understanding, I could push the rod with a much lower force, as my extremity of the rod would not "know" the rod is so heavy. It seems the part of the rod that is several light-minutes away would not affect my push. Am I right? What would happen eventually? Would the rod gradually bounce back the whole meter? Or only half of it? Also, would it be correct to guess that there wouldn't be notable differences between pushing a rod 1 light-year long, and a rod that goes up the way to Andromeda galaxy?

| How do scientists collect so much data on planets that are hundreds+ light years away? Posted: 21 Dec 2019 08:38 AM PST I'm reading about exoplanets hundreds of light years away and scientists know the size, density, and composition of the planet (IE: earth like, gas, etc) how in the heck can they estimate these things with accuracy? Can telescopes see hundreds of light years away with clarity enough to see what the planet looks like? Also, how can they tell how old a star is?? [link] [comments]  |
