Does General Relativity provide a value for $G$? [duplicate]
It only recently was specifically pointed out to me that Einstein was right, and Newton was wrong.
Newton wasn't wholly wrong. He theorized that gravity was a force that acted between bodies, and came ...

${}$Can the gravitational constant $G$ be calculated theoretically? [duplicate]
In an answer to a previous post of the same question, it was stated that the gravitational constant can not be determined theoretically yet! From my perspective, the reason this is not yet possible ...

Analogue of $\varepsilon_0$ for gravitational mass? [duplicate]
In electric fields, we usually define the dielectric constant in vacuum as:
$$K_C=\dfrac{1}{4\pi\varepsilon_0}$$
Why don't we define the gravitational analogue, "digravitational" constant:
$$\Delta_0=...

Gravity Relative to Mass?
Why is it that, in basic physics, it is taught that the acceleration of gravity is the same for objects of any mass (at a constant distance from earth)? Why then is the acceleration of gravity ...

How can gravity truly be infinite?
From my knowledge, gravity is infinite and extends throughout all of space. It diminishes as distance increases but is still present everywhere. So given enough time, no matter where something is in ...

How is the most accurate value of $G$ measured?
How do modern scientists update the measurement of $G$, the gravitational constant? Is CODATA the authority on this measurement and the experiment?

Can the gravitational constant $G$ be calculated theoretically?
We know all that the gravitational constant is $$G=6.67428±0.00067\times 10^{-11}\mathrm{m^{3} \:kg^{-1} s^{-2}}.$$
But can we calculate it theoretically?

Gravitational Constant in Newtonian Gravity vs. General Relativity
From my understanding, the gravitational constant $G$ is a proportionality constant used by Newton in his law of universal gravitation (which was based around Kepler's Laws), namely in the equation $F ...

Is $4 \pi G$ the true most fundamental gravitational constant? [closed]
Newton's law of gravitation is:
$$F = G m_1 m_2 \frac{1}{r^2}$$
It looks simple and natural.
But that's only in 3 dimensions. Let's look what happens in $n$ dimensions:
$$n=2 : F = 2 G m_1 m_2 \...
