If anything is ubiquitous it certainly is
gravity. It exists in every corner of the universe and affects
all sizes of bodies, from atoms to humans to galaxies.
Everything is attracted to everything else with no apparent
connections, no strings attached. Earth holds onto its rocks,
animals and whatnot, our sun holds its planets in their orbits,
our Milky Way galaxy guides the path of the sun on its celestial
journey. How does all this happen? What property of the universe
is responsible? Can we figure it out?
Yes we can, and the figuring-it-out
business began with Galileo
discovering how things fall, Kepler
working out the laws of planetary motion, and
Newton deriving the first theory
of gravity. All this and gravity was still a mystery. Scientists used
descriptive terms like “field theory” and worked out useful
mechanisms but increased little our understanding of gravity.
Around
1915 Einstein developed his General Theory of Relativity and
reasoned that the geometry of space itself is curved by matter,
causing bodies to appear to be moving in curved paths. And
there, dear reader, the theories came to a screeching halt. How
does matter curve space? And what does “curved space” mean? For
that matter, what is matter? For the past 40 years scientists
have wrestled with esoteric things such as String Theory and
Quantum Gravity trying to understand the gravity force. The
results have been rather dismal. Where do we go from here?
It’s easy; we change Einstein’s viewpoint a
bit and realize that:
1. Space has the property of energy. There
is a real energy of space. Call it
Space-Energy.
Einstein’s curved space becomes curved space-energy. How is
space-energy curved?
2. Particles including neutrons, protons and electrons, the
basic stuff of matter are concentrations of space-energy.
3.Each of these particles by virtue of this
concentration of space-energy left a dent, or curvature in the energy
of space.
4. This curvature is the force we call
gravity. That’s it, we’re
done.
This theory enables us to develop a
mathematical expression of gravity because we know the energies
involved, and can calculate the curvature of the space-energy.
We can actually figure out what our Universe is doing. What fun this is!

Cosmology – Newton’s gravity
constant, G, gives us space tension and tells us how
gravity changes, and what that change is doing to the
universe as it expands.
These ideas are
discussed at some depth in my little book,
Gravity
Decoded, Exploring the Structure of Space-Energy,

Amazon.com and through other booksellers (ISBN
