This post is not a post. It’s just a reminder for myself to look into *gravitational waves* at some point in time. We know how electromagnetic waves travel through space: they do so because of the mechanism described in Maxwell’s equation: a *changing* magnetic field causes a *changing* electric field, and a *changing* magnetic field causes a (*changing*) electric field, as illustrated below.

So… Electromagnetism is *one* phenomenon only, but we do analyze the **E** and **B** fields as separate things, as the equations below illustrate:

**B** is co-defined with **E**, and then all of the dynamics work themselves out through the ∂E/∂t and ∂E/∂t functions. Now, when talking gravity, we only have *positive *‘charges’, referred to as *masses*, **always***attracting each other*, but that doesn’t matter all that much: **Coulomb’s and Newton’s Law have the same mathematical structure** (as shown below), except for the minus sign, and so there *must *be some equivalent to the electromagnetic wave, explaining *gravitational waves *, using the same mathematical concepts, as **a propagation of a force on** a ‘unit charge’ (so that’s

**a unit**

*in this case) using the very same concepts, i.e. the concepts of a*

**mass***field*–

*two*separate fields, I should say, just like

**E**and

**B**– and of its

*flux*and

*circulation*.

So we’d have an **E _{G}** and a

**B**field, so to speak, or a

_{G}**G**and a

_{E}**G**field, and formulas for the flux and circulation of both, resembling Maxwell’s equations. In fact, they’d be the same, more or less. It’s a powerful idea, and I am sure the idea has been fully developed elsewhere. In fact, I quickly

_{B}*googled*a few things, but it seems that the whole area is a pretty new area of research, both theoretically as well as experimentally—to my surprise!

Hmm… Interesting idea, but I’ll need to do a lot more analysis to be able to grind through this… One day, I will… The first thing I need to do, obviously, is to *thoroughly *study how these equations for **E** and **B** above can be derived from Maxwell’s equations. I’ll need some time for that, and then I can see if it’s consistent with Einstein’s special and general* *theories of relativity.

I’ll update you on progress. 🙂
