- 1.

the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
· 2.
extreme or alarming importance; seriousness.
“crimes of the utmost gravity”
We are all subject to gravity, whether it be that force pulling us towards the center of the earth, or being subject to situations of extreme and/or alarming seriousness or importance. Gravity changes space and time—warping/bending them to an inescapable fate.
What is meant by it all? No matter if we are out of the gravitational pull of the earth or are stuck firmly here on the ground, our mass is still the same. Mass is calculated by multiplying our volume by our density. Think in terms of how much matter can one stuff into the skin sack that encloses our body. So all things being equal, not everyone’s mass is the same.
But gravity, oh wonderful gravity, that is the defining factor that imposes the bad news of how much we weigh. Without going into a whole long explanation of what consists of weight, I’ll just remind you of Sir Isaac Newton’s Law that shows that no matter the actual size of objects (what weighs more, a pound of feathers or a pound of lead) but rather the effect that gravity has on the mass (volume X density =mass)of an object.
You can ask yourself, why is Mike writing on this subject? Well, in my daily thought processes questions always arise that lead to asking silly questions and then looking for answers. In this case, I was intrigued by the dual meaning of the word—gravity.
Which leads me to talk about the second meaning of that word. The first thing that comes to mind is the image of a grave. According to the Oxford dictionary they are not related in any obvious way but, the symbol of the grave relates to the extreme seriousness of a situation. Whereas, “we felt the gravity of formal proceedings of the government”, is not the same as “John was gravely ill”.
Are human beings able to exist long term in any environment without gravity? It would seem not. Our physiology has been designed for our life on this planet. On Jupiter the gravity would crush us, on the moon we would have serious health issues after a period of time, Mars the same. So, our collective dream of traveling to the stars surely is just that, a dream. Unless, there is some provision for generating a faux gravitational pull, we are stuck on this spaceship (earth) for the foreseeable future.
Is that such a bad thing? Does anyone think we could escape the problems we have as humans on this earth? Won’t we just take them with us if we try to reach out to other homes in the universe? I think that we must deal with those problems here and now with all importance and seriousness.
In my youth, before Bill Cosby became full of himself, he was a funny comedian, virtually unknown. He got noticed and put his jokes on a LP vinyl record of which I had. One of the gags had the question “Why is their air?” and he had funny simple answer about filling basketballs, footballs, etc. The real reason that we have air is due to gravity—exerting its inexorable force on the mass of gasses that make up our atmosphere.
Gravity in the first definition is relatively constant now and into eternity. We likely won’t be able to change that. As for the second definition, we must recognize and deal with the gravity of our situation and let the dream of escaping this gravity go for the present.
