What is gravity?

“Gravity is a force pulling together all matter (which is anything you can physically touch). The more matter, the more gravity, so things that have a lot of matter such as planets and moons and stars pull more strongly.

Mass is how we measure the amount of matter in something. The more massive something is, the more of a gravitational pull it exerts. As we walk on the surface of the Earth, it pulls on us, and we pull back. But since the Earth is so much more massive than we are, the pull from us is not strong enough to move the Earth, while the pull from the Earth can make us fall flat on our faces.

In addition to depending on the amount of mass, gravity also depends on how far you are from something. This is why we are stuck to the surface of the Earth instead of being pulled off into the Sun, which has many more times the gravity of the Earth.”  Courtesy Northwestern Education.

Dr. Andrew Arnold says, ‘I was recently watching an interview with Tom Cruise talking about his latest movie, MI6. He talked about a scene where they created an actual set inside a plane then took it up to 20,000 ft.’

At this height, the plane starts to align with the natural curvature of the earth.

This is when the Parabolic curve phenomenon applies.

“When you kick a soccer ball (or shoot an arrow, fire a missile or throw a stone) it arcs up into the air and comes down again … following the path of a parabola!” Courtesy mathsisfun

At the top of the curve the ball is essentially weightless, ‘0-G’. So, in the MI6 scene at the top of the plane’s trajectory, for about 30 seconds Tom and his crew were weightless. Apparently, they needed to shoot the scene 64 x, clearly a huge budget!

What’s really interesting is how quickly they returned to normal gravity. In fact, it was instantaneous, well, according to Newton’s Law of Gravitation, 9 m2.

This means when they’re counting down to normal gravity they hit the ground with a thump.

Think about this. We’re constantly resisting gravitational forces walking the earth. This means our postural muscles are working 24/7 literally keeping us upright.

We are being pulled towards the earth in every moment which is possibly one reason we lose height as we grow old. I believe it certainly contributes to postural distortion, in particular, forward head posture.

Think about how quickly you hit the ground in the case of fall, or fainting. That’s 9 m2!

So, my point is, finally! We all need to maintain a daily postural exercise plan to fight gravity, otherwise, it is inevitable your head will further forwards, the mid backs will hunch more, your low backs will sway more, the knees will roll inwards, and your feet get flatter, and your spines compress.

So, talk to your physical therapist, your Chiro, Physio, P.T., Myotherapist and get onto this. Grab some exercise bands and start using them daily.

And remember there are a right way and a wrong way to make sure you get advice.
