OK, let's blame it to the festive season that you have gained a few pounds in the last 2 months... And now, you have a vacation lined up, after which you will definitely be posting in quite a few pictures to flaunt a little about your latest vacation.  But then, you would want to be in shape before all this happens and someone points it out on your FB wall and embarrass you for no reason. So, here begins your weight loss spree..! It's  12 am, and you're surfing some weight loss tips.

What if, everyone on Earth stood as close to each other as they could and jumped, everyone landing on the ground at the same instant?

At the start of the scenario, the entire Earth’s population has been magically transported together into one place. This crowd takes up an area the size of Rhode Island. But there’s no reason to use the vague phrase “an area the size of Rhode Island.” This is our scenario; we can be specific. They’re actually in Rhode Island. At the stroke of noon, everyone jumps. As discussed elsewhere, it doesn’t really affect the planet. Earth outweighs us by a factor of over ten trillion. On average, we humans can vertically jump maybe half a meter on a good day. Even if the Earth were rigid and responded instantly, it would be pushed down by less than an atom’s width. Next, everyone falls back to the ground. Technically, this delivers a lot of energy into the Earth, but it’s spread out over a large enough area that it doesn’t do much more than leave footprints in a lot of gardens. A slight pulse of pressure spreads through the North American continental crust and diss...
