Podcast: Gravity
Written by Nancy Atkinson
You seem to like a nice series, so here's a new one Fraser and Pamela have been thinking about. Over the course of the next 4 weeks, they're going to cover each of the basic forces in the Universe. And this week, they're going to start with gravity; the force you're most familiar with. Gravity happens when masses attract one another, and we can calculate its effect with exquisite precision. But you might be surprised to know that scientists have no idea why gravity happens

I personally am wondering just how much you guys are going to have to say about the weak nuclear force beyond saying it's responsible for beta decay which is just one of the many types of radioactive decay.
The gravity program was good BTW. Keep up the good work.

To quote The Tick, "Gravity is a harsh mistress".

Could gravity simply be the weak nuclear force within the atoms of a given mass (earth) combining in a way that attracts or links-up with the weak force of other atoms in a near-by mass (moon?) The reaction might be similiar to opposing pole attraction like that of common horseshoe magnetics. The greater the mass, the greater the attraction. Occum's razor comes to mind.

I think of a gravitational field as an interference/interfacing pattern in an otherwise expanding universe. i.e. the quantum field of space interfacing with the quantum energy of matter thus interfering locally with the former's general expansion.
