Notes - more on gravity


       Mid-morning. Jadah just jumped off your chest and climbed up on her fluff rug covered box to bask in a sunbeam – a form of cat heaven. Carol is in the office on her iMac. Spooky is unseen and unheard at the moment. You have forty-minute exercises this morning and that is it for the week. You have been on target with these since Christmas. Thus begins your day. – Amorella

       0953 hours. Jadah is such a cutie. Carol was reading the entertaining article on Trump in the latest Harpers at breakfast. It is always a joy to hear her laugh out loud while reading something. Paul Wood is the author’s name if I remember right – a former BBC correspondent in the Middle East. Carol reads articles from my magazines once in a while, which I like. Eventually I send the mags to Kim and Paul.

       Late afternoon. You are facing west towards the center of Rose Hill Cemetery. Carol is taking a shorten walk as she has the wrong shoes. Lots of flags for the war veterans. – Amorella

       1708 hours. We were running an errand (cat litter needed) and I noticed the right front tire was low. We bought the litter and once home I filled the tire and took it up to Barnes Garage in Mason. Hilliard Barnes owned the garage in 1977 and a nephew of his Dale worked for him. We used their services until we got Hondas. He would work on VW’s and Fords. They are very friendly and honest dealing people. A few years ago Hilliard died, six months after retiring. Sad. Dale has the business now and when we have tire problems or something not too complicated we still take the cars up to him. His young assistant took the tire off and checked it out; he couldn’t find any problems. Dale drove in as we finished and saw me give the boy a tip. I told Dale I insisted because I didn’t want the boy getting into trouble. Hilliard and Dale would never accept a tip for changing a tire or anything to that effect; usually it was/is ‘no charge’ or minimal. Here comes Carol.

       Not quite dusk. You are home from a quick supper at McD’s – two Egg McMuffins and Carol had a medium Coke, you had a Wendy’s vanilla Frosty. Home and Carol is watering petunias before taking a shower. So far, the air is holding in the tire.

       1947 hours. I’m leaving it in the driveway in case it is flat by morning. A couple of days ago you mentioned ‘nothing’ and ‘gravity’.

From 25 May posting

. . . I am pondering: ‘a tiny hole in a floorboard causing a nail to enter and close it’. Why would the hole exist before the nail?

       Nothing exists then gravity, that’s the analogy. - Amorella

       1621 hours. This doesn’t make sense. How can gravity come from nothing?

       Distortion. – Amorella

       1652 hours. Nothingness has distortions near its edge?  First, a definition:

** **
Nothing is a pronoun denoting the absence of anything. Nothing is a pronoun associated with nothingness.

In nontechnical uses, nothing denotes things lacking importance, interest, value, relevance, or significance. Nothingness is the state of being nothing, the state of nonexistence of anything, or the property of having nothing. . . .

       You are not keeping to the point of the exercise boy. - Amorella

       2158 hours. Okay then – the only thing that a vacuum can hold is consciousness, and if a vacuum contains not-a-thing but rather consciousness (because it is non-material as is the heart and soul) then consciousness [i.e. mind-like] may indeed be timeless. This is what I have constructed from this material presently.

       2000 hours. Now I know where I was but I don’t think I resolved the problem between Timelessness and Time. You say, “Nothing exists then gravity, that’s the analogy. Here are two definitions:

gravitynoun

1 Physics the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.

• the degree of intensity of this, measured by acceleration.

Gravity (or gravitation) is a natural phenomenon by which all things attract one another including stars, planets, galaxies and even light and sub-atomic particles. Gravity is responsible for the formation of the universe (e.g. creating spheres of hydrogen, igniting them under pressure to form stars and grouping them in to galaxies). Gravity is a cause of time dilation (time lapses more slowly in strong gravitation). Without gravity, the universe would be without thermal energy and composed only of equally spaced particles. On Earth, gravity gives weight to physical objects and causes the tides. Gravity has an infinite range, and it cannot be absorbed, transformed, or shielded against.

Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915) which describes gravity, not as a force, but as a consequence of the curvature of spacetime caused by the uneven distribution of mass/energy. For most applications, gravity is well approximated by Newton’s law of universal gravitation, which postulates that the gravitational force of two bodies of mass is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Gravity is the weakest of the four fundamental interactions of nature. The gravitational force is approximately 10−38 times the strength of the strong force (i.e. gravity is 38 orders of magnitude weaker), 10−36 times the strength of the electromagnetic force, and 10−29 times the strength of the weak force. As a consequence, gravity has a negligible influence on the behavior of sub-atomic particles, and plays no role in determining the internal properties of everyday matter.

On the other hand, gravity is the dominant force at the macroscopic scale, that is the cause of the formation, shape, and trajectory (orbit) of astronomical bodies, including those of asteroids, comets, planets, stars and galaxies. It is responsible for causing the Earth and the other planets to orbit the Sun; for causing the Moon to orbit the Earth; for the formation of tides; for natural convection, by which fluid flow occurs under the influence of a density gradient and gravity; for heating the interiors of forming stars and planets to very high temperatures; for solar system, galaxy, stellar formation and evolution; and for various other phenomena observed on Earth and throughout the universe.

In pursuit of a theory of everything, the merging of general relativity and quantum mechanics (or quantum field theory) into a more general theory of quantum gravity has become an area of research.

Carol wants to watch the news. Later, dude. Post. Amorella
