Peter Duffett-Smith's amazing paragraph.
"A celestial observer viewing the solar system from a great distance would not, however see the Moon making loops in space about the Earth. Rather, he would describe the situation by saying that the Moon is in orbit around the Sun, as is the Earth, and that the effect of the Earth's influence is to make the Moon's orbit wiggle a little as the relative positions of the Earth and Moon change. This is because the Sun's Gravitation force on the Moon is much greater than that of the Earth, even though the latter is nearer. "
I would like to use this paragraph to describe gravity.
"This is because the Sun's Gravitation force on the Moon is much greater than that of the Earth, even though the latter is nearer". The Sun is an absolutely massive radiation emitter. Its primary radiation strength extends to beyond Mars, Its secondary fields extend past planets into the ice fields beyond Pluto. These areas of radiation are well defined.
At this point lets consider our star has no orbiting debris. Also our star does not exist before time T0. Time exists before T0 but the Baryonic matter star does not exist. We have a Riemannian manifold in Hilbert space. This is a massive space. Each point in the space is filled with a Dark Energy. The Dark Energy contains information on the Dark Matter particle that fills the Dark Energy space.
Upon time reaches T0 our Baryon filled star winks into existence inside our space as a manifold. As the baryonic radiation emissions of the star expands to it maximum, Dark Matter particles are pushed back, repelled by the existence of Baryons. Within days Dark Matter particles have been pushed back past ~3 au. Now Dark Matter particles have mass. Our baryon radiation from the star has traveled far enough that there is enough distance between them to no longer be strong enough to push the now pressurized Dark Matter particles. Dark matter particles start to push back on the baryons. We get an equilibrium between dark and baryonic matter. There are some areas of Void between the Dark and Baryonic particles. This is important.
Now between the star’s edge and the edge of the Dark matter is 3 au. This area is Void except for odd bits of baryonic radiation. Each bit of baryonic radiation has its own magnetic field and charge. Non-baryonic radiation (photons, free electrons) pass through the non-baryonic dark matter. This is why we can see galaxies through the soup of non-baryonic dark matter.
So in our space we have the star emitting its baryonic radiation and its non-baryonic radiation in the form of photons and others. Folks on the planet orbiting the neighboring star will see our existence in a few years.
this retired scientist sees everyone lost in detail with no commonly held overview-common meaning a vast majority at minimum-every human being understands gravity in their guts and have no real problem describing it--science has become geek-populism
ReplyDeleteYes, I agree on both counts.
ReplyDeleteEvery human can drop a ball a explain gravity in some form. And to the need of that person the answer shows levels of complexity. For those of us who wish to mine the moon, we need to know exactly where it is.
The same could be said for sex. Every human can describe it. How each human responds to sex is different; some enjoy it, some kill over it. I think what this geek wants to know is how does the neural network generate from C,N,H,O.

What a great resource!
ReplyDeleteAnon,
ReplyDeletePractical Astronomy With Your Calculator is a great resource. There are not enough accolades to pour upon Peter Duffett-Smith. I bought this book in the late 80s and it has never been far from my workspace.
Thanks for reading my work.
Aaron
