  "Your fragile face scraping against the rock surface will cause friction, which is frankly inconvenient for the maths."

  Repeatedly falling through the hole, emerging at the other end of the sphere and plummeting once again is technically orbiting (mathematically).

  <a href="https://www.youtube.com/watch?v=s94Gojs3Ags&amp;t=1100">18:20</a> Imagine that, you fell all the way through the earth and came out alive on the other side only to get obliterated by a tennis ball going at 28,000km/h that you yourself threw. That&apos;s karma for daring to drill through our beloved earth I tell you.

  “Earths density does not change” well that just triggered all the geologists. The center of the earth is much more dense than the exterior. In fact the core is a mars scized chunk of iron! Now if you were to just fall through the iron bit the time to fall through would less than the 42 minutes. This means that going through the core would take LESS TIME! Right? Or am I missing something?

  Walking through Fremantle today and my son grabs my sleeve - &quot;Dad, Dad, that&apos;s the guy who does those cool YouTube videos!&quot; I learned two things today:<br>- The world is smaller then you think. <br>- My son is a bigger nerd than I realised.

  I knew the answer would be 42.

  It is actually more fun with air resistence. You will have damping that willl give you some decaying oscillation that will likely end you sitting susupended in the middle of the earth.

  &quot;assuming there is no air resistance&quot;<br>me, a highschool student: &quot;air resistance? What air resistance?&quot;
