      Lets say you drill a hole through the centre of the planet (ignoring the fact that there is heat to contend with)

      Then you jump in the hole. Will you fall out the other side?

        Yes. I do not even belive that Aussies do not fall off the planet. ๐Ÿ˜’

          If the heat does not melt you the pressure will crush you.

                no. You'd have to go faster than terminal velocity to get through.

                ...though in a vacuum, yes.

                Aw damn, already shot down. Oh well.

                  If gravity attracts you to the center of the earth, you should stop right there.

                    Would fall out the other side?

                      Just stuck on center like a magnet.

                        You're saying that when you jump in you stop at the centre and don't exit the other side?

                        If so incorrect

                          Ignoring the actually insurmountable issues of heat/pressure/radiation/forces etc... ๐Ÿ˜ฎ
                          And assuming that both ends of the hole are the same distance [to within a few meters] from the center of gravity of the earth... ๐Ÿ˜ฒ
                          If you did jump in you would fall, fall, fall... accelerating 'down' towards the center under the force of gravity [assuming 'air-resistance' you'd reach a terminal velocity - like a sky-diver], then you'd pass through the very center, and because of your momentum you would continue 'up' towards the other end of the hole... However, because you are now going against the force of gravity you'd decelerate, but you'd almost reach the other end before you slowed to a dead-stop and then started falling back towards the center again. Because your second 'start' is nearer the center then your momentum will be slightly less, as you again pass through the center and approach the other end... this time your trajectory is reversed a little nearer to the center... This cycle repeats with you falling back and forth, but getting progressively nearer the center with each reversal of trajectory. Eventually the reversals will become so frequent that you will effectively be oscillating around the center by an insignificant amount; theoretically after long enough had elapsed you might become stationary at the center, but in practice there are so many variable factors I suspect that you would never quite 'stop'...
                          Note: if you were agile enough... on the first 'fall', just as you approached the other end and slowed to a standstill you could 'grapple' onto the tunnel's wall just below the rim, so with a little climbing 'up' you could pop out at the other end... but I suspect you'd be a bit knackered by then [if not dead] !!!

                            I can't prove it as I'm not physician, but if it is the center that attracts you if you pass beyond due to acceleration, you should be attract back?

                                      If a vehicle is travelling faster than the speed of light what happens when it turns it's headlights on?

                                          So if you were travelling next to the vehicle at the same speed would you see the light on of off?
