The sky is falling, THE SKY IS FALLING!!

I recently picked up a book, 'The Elemental You' by Linsey Dawson, which talks about the four elements of earth, wind, water and air and how everybody is predisposed to one of these elements. While talking about the earth she made a comment about how we feel the earth through our feet as we walk on the ground, which we are rooted to due to gravity, and all the while the earth is spinning and we have no physical sensation of this. These comments triggered a cascade of thoughts which just pose more and more questions! Gravity causes objects to fall to the earth, just ask anyone who has done a skydive! I did a skydive last February, and as I was plummeting to the ground, getting faster and faster, I realised that the sensation of falling wasn't there - instead, it's like standing on the top of a mountain in a gale force wind (see cheeks in pic)! 

Yes, I am Superman!

So now we have two instances of the body being completely fooled - one when falling to the ground and another as the earth spins. Still with me? - OK, now lets look at the earth and the universe on a macro level. On earth we have gravity which pulls everything to the center of the earth and sometimes we don't feel it, as with the skydive experience. Add to this that we don't feel the earth spinning. So now for my questions: If we don't feel the sensation of falling on earth, and we can't sense the movement of the earth, could the earth be falling? Its in Space, aka, nothing! And if so, falling where? Falling down, up or sideways? Into what? What happens when we hit the "ground"? Gravity keeps the earth in orbit around the sun, which is in orbit around the supermassive blackhole at the center of the milkyway - is the milkyway orbiting something and, i dunno, is it falling too? Maybe Henny Penny had it right....
