Question about gravitational waves

Someone asked :

Since dark matter is thought to interact gravitationally, could clues about it be discerned in gravitational waves?

And Founder of APG ( FAPG ) was answering :

As stated, this is just an idea, In our opinion, this is a misconception

Supplementary : 
Even if we assume that this misconception is acceptable based on general relativity, still in our opinion, it is not possible to discern clues to gravitational waves. (M.Sh)

Question about Amplitude of Oscillation

Someone asked :

A swing is 2 m long. How often do you need to push it to increase its swing's amplitude the most?

APG Institute was answering :

In the simplest case, we can consider the swing as a simple pendulum, and by calculating the rotation period of the simple pendulum, we obtain the time interval between each stroke:

T = 2π√ (L / g) = 2π√ (2/10) ≈2.8 s

If we can ignore the mass of the rope over the mass of the hanging object, then the simple pendulum assumption is acceptable. But otherwise we have to calculate the rotational inertia of the whole system and write Newton's second law for it, and by solving the resulting differential equation, we get the rotation period. (M.Sh)

Question about Newtonian Law

Someone asked :

What Newtonian law is the most likely to be broken eventually?

And Founder of APG was answering  :

In the APG Institute, we found that all Newton's rules need to reform. But the third law is most needed. When two particles collide, the effect of each on the other is independent of each other.

Question about Propagation of a Mechanical Wave

Someone asked :

What are the basic properties that a medium must possess to have the propagation of a mechanical wave? 

 

And Founder of APG ( FAPG ) was answering ?

The necessary condition is the elasticity of the medium. This means that for a wave to be produced in a medium, the medium must be elastic and continuous. After the wave is generated, we must examine the propagation conditions. What are the conditions for wave propagation?! Here, the Physics of scales helps us. we measure the parameters of the wave (note that the speed of the wave is determined by the coefficient of elasticity and density of the medium) and we compare them. If the amplitude is greater than the wavelength, the wave propagates easily, but if it is smaller, the wave stops (Absorbed by the medium). (M.Sh)

Question about Accelerated electrons

Someone asked :

Why do accelerated electrons radiate energy, i.e., in particle accelerators, and do they lose their effective mass as a result?

And the founder of APG ( FAPG ) responded :

 

Short answer :
Yes, they may lose their effective mass as a result of this radiation.

Supplementary :
Based on the concepts and physical relations (Maxwell's equations, etc.), the accelerated (free) charged particle emits electromagnetic energy. The cause of this electromagnetic radiation is the change of electric and magnetic fields. In synchrotron accelerators, electrons accelerate and radiate under the influence of a magnetic field. These electrons are in the relativistic region, so this radiation may be associated with their energy conversion (due to the increase in their relative mass). That is, as a result of this radiation, they lose part of their effective mass. (M.Sh)

Question about Shape of Electron is Round

 Someone asked :

"Shape of Electron Is Round" Why is this surprising and even unsettling for some physicists?

And this answer was confirmed by the founder of APG ( FAPG ) :  

Scientists have predicted that the universe has an equal amount of matter and antimatter, and there must be symmetry between the amount of matter and antimatter.

But Hudson's measurements (due to the symmetry of the shape of the electron) showed that the universe was made almost entirely of matter and that there were no antimatter.

Some physicists were thrilled because what was observed did not match their prediction (and of course this is a cause for concern)

But Hudson's discovery does not surprise us in the APG Institute, because we predicted (or believed) that the universe is full of matter and there is no antimatter, and Hudson's observations only confirm our opinion.

And there is no wonder or worry. (M.Sh)
