## Quantum G?

Fascinating snippet in a mag lately. The right
combination of the Planck mass and Planck time
and Planck length produces the value of G. Never
heard this before. Is it accurate? Suggests
gravitation is derived from electrons I think.

2. You might want to check the units. I saw something like this once, but the units were meaningless, and it only worked in the MKS system.

That was quick! Will get round to it
thanks.

Well, all the lengths, the Planck Values, use h, G and c. In fact, this is called, hGc-physics. Rearranging formula's for G would not be too hard.

For instance, you have

Square it then rearrange the formula for

Is this what you meant?

6. Since all the Planck units include G in their definition, it's hardly significant that algebraically manipulating them can give the numerical value for G.

Right.

So when you have figured out what the OP is talking about, maybe you could come and tell me, instead of standing in the back criticizing?

He's talking about how algebraically manipulating Planck length, Planck time, and Planck mass in the correct manner has G fall out. If he's talking about more than that, he'd include a link to the article.

Right, this is what I thought, hence the answer I gave.

Heh! So it is all circular? Pity. It
was something in the latest issue of
the British mag Astronomy Now.

Aethelwulf,

Our primary rule around here is politeness. That comment was rude. You can disagree, but do so with less attitude. Thanks,

Sounds a bit hyped, or by an editor who did not realize how insignificant the idea is.
