How Gravity Really Works.

We’re all familiar with the concept of gravity: 2 bodies of mass, no matter how or small and regardless of the distance between them, are attracted to each other. As a force it’s pretty weak, even when the two bodies are close to each other, as you can overcome the gravitic forces of an entire planet by simply standing up. However the fact that its range is unlimited and that it doesn’t appear to discriminate as to what it acts on is what makes it such a fundamental force in our universe.

Whilst that understanding is probably good enough for a general understanding of its mechanism of action it in fact is far more complicated and interesting than that and the following video is probably the best way of describing it I’ve seen in a long time:

It’s not a perfect simulation, as they mention in the video, but it does give you a really great insight into how the general relativity way of explaining gravity works and how it works with other well known theories like orbital mechanics. I reckon with a little additional engineering you could make something that functioned like a nearly ideal gravity field something which would be awesome in a science museum like Questacon here in Canberra. It’s still great in its current form though and hopefully we see similar things make its way into the science labs at our schools.
