Hi everyone! Welcome back to Science Sunday. Just as a note, I have TWO giveaways going on now: one for a copy of A PERFECT DAY (just leave a comment here), and another for SOCIAL MEDIA JUST FOR WRITERS (tons of ways to gain entries here). Please stop by the links to enter :)
There was one aspect that had hubby chuckling, and that was a feature of the movie called The Fall. This was basically a means of traveling to the other side of the globe through traveling through the (near) center of the earth. This was basically the avoid traveling through contaminated areas (even though apparently they have the ability to fly through them anyhow, as demonstrated later in the film...). So, yeah, this was amusing to hubby, as during the middle of the trip, there was a moment of weightlessness as gravity was "reversed" and the passengers started traveling to the opposite side of the planet. This moment plays a part in the plot of the movie even!

I watched this go up & down while in Vegas this week
and seriously never want to try it!
It would be free-fall not just until one reached the center of the earth, too, but until you reached the opposite side of the earth. There, something would have to catch you, or you'd go shooting off into the air like the earth was spitting you up :) If nothing caught you, well, then you'd eventually be subject to gravity again, and then fall back to the earth again (and right back through the hole to the other side...). Actually, you could end up falling through the earth, from one side to the other, over and over again.
Anyhow, that's your physics lesson for the day. Anyone out there feeling up to attempting to tell me how long it would take to go from one end of the earth to the other? (Assuming the diameter of the earth is 12,756.2 kilometers).
A little hint: Force due to Gravity: F=GmM/r^2
