The earth

The video about falling through the earth was quite interesting I had seen a video before about it but it wasn’t looking at the mathematics side of it and was just looking at the other side. In the video, they started off doing quite rough calculations with 42 mins. He also mentioned that that was the amount of time it would take for you to go around the outside aswell. In the end shaved some time off by taking into account other factors that they hadn’t before, at the end of the video it came out to around 38 mins and 6 seconds in total from pole to pole.
