if you dug a hole straight down - from one end of the earth to the other end, would you be able to fall from this hole all the way to the other side?
i remember watching discovery science about this.its possible to go to anywhere on earth on 40 mins by underground train.digging a hole at one point through the earth and the next hole on the other side can be at any point on earth.time taken to travel to anywher around earth will still be 40 mins.the tunnel is vacuum so the train wont lose momentum due to air friction.but in reality its still impossible to execute this
