An Elucidation of the Blog Title

Brief History:

Beginning in the 1500s, astronomers Galileo and Brahe discovered that the earth and other planets revolved around the sun. Kepler showed that they moved in an eliptical orbit, not a circle. The question was why. Isaac Newton (1642-1727) was the first to develop a quantitative theory of gravitation, holding that the force of attraction between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them.
Albert Einstein (early 1900s) proposed a whole new concept of gravitation involving the four-dimensional continuum of space-time, which is curved by the presence of matter (or the "warping" of space and time”). In his general theory of relativity, he showed that a body undergoing uniform acceleration is indistinguishable from one that is stationary in a gravitational field.
Though gravity is the weakest of the four known forces (gravitational, electromagnetic, strong, and weak), it shapes the structure of stars, galaxies, and the entire universe. The laws of gravity determine the trajectories of bodies in the solar system and the motion of objects on earth, where all bodies experience a downward gravitational force exerted by earth's mass, the force experienced as weight.

Short Definition:

Universal force of attraction that acts between all bodies that have mass

Conclusion:

Now that “gravity” has been described in an all-together feeble display, I will venture to explain the blog title “Finding Gravity.” The labor of Newton and Einstein is surely worthy of finding residence in the title of a blog; however, I am simply using the term “gravity” to mean IMPORTANCE or SIGNIFICANCE. Therefore, the title suggests that which the reader will have to accomplish (if they deem it worth the effort) in the words and work written herein. I expect that I will never supply many thoughts that are important or significant; however, this blog is more for myself than those who read it and I guess therein lies its purpose-to provide an outlet for areas of weakness and to create I new arena for learning.
