Gravitational Constant: Questions and Ideas

AI Thread Summary
The discussion explores the implications of an increased gravitational constant (G) on life on Earth and other celestial bodies. Participants speculate that animals might adapt by developing stronger muscles and larger organs, while humans could face more health issues like back problems. Additionally, changes in gravity could affect ocean wave heights and sports performance, such as cricket. The conversation emphasizes the vast and varied consequences of altering the gravitational constant on the universe. Overall, the topic raises intriguing questions about adaptation and physical laws in a hypothetical scenario of increased gravity.

Hey, I have got some guestions, when I philosophized with me friends...

We have classic gravitational constant, say G... And now, constant is 2G, 5G or 100G... (increases).
Others constants and physics legislation is normal.

THEREAFTER...

How is live on Earth?
And other planets and universe object?

Have you got any idea?

Thanks and sorry for bad Englist.

If gravity increased I think many animals would slowly adapt by developing stronger leg muscles, and bigger hearts and lungs. Though we'd probably suffer more back problems, and do more damage whenever we tripped in the street.

Ocean waves might not be as high, and it would become rare to hit a 6 in cricket.
 
When G increases there'll be various innumberable changes made to the whole universe.:-p

Thread 'Gauss' law seems to imply instantaneous electric field propagation'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (First part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8 and stuck at some statements. It's little bit confused. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. Solution : The surface bound charge on the ##xy## plane is of opposite sign to ##q##, so the force will be...

Thread 'Simple thought experiment with Stefan-Boltzmann law: energy'

Dear all, in an encounter of an infamous claim by Gerlich and Tscheuschner that the Greenhouse effect is inconsistent with the 2nd law of thermodynamics I came to a simple thought experiment which I wanted to share with you to check my understanding and brush up my knowledge. The thought experiment I tried to calculate through is as follows. I have a sphere (1) with radius ##r##, acting like a black body at a temperature of exactly ##T_1 = 500 K##. With Stefan-Boltzmann you can calculate...
