I copy from alpha experiment website:

"Today, the ALPHA Collaboration has published results in Nature Communications placing the first experimental limits on the ratio of the graviational and inertial masses of antihydrogen (the ratio is very close to one for hydrogen). We observed the times and positions at which 434 trapped antihydrogen atoms escaped our magnetic trap, and searched for the influence of a gravitational force. Based on our data, we can exclude the possibility that the gravitiational mass of antihydrogen is more than 110 times its inertial mass, or that it falls upwards with a gravitational mass more than 65 times its inertial mass."

Keep in mind that of a typo error: "...the gravitiational mass of antihydrogen..."!

So, billion of euros and the output is not even spell-checked!

Dear Demetris,

The word "antihydrogen" might not be a typo, because it showed up in their paper as well. They seemed to coin it in purpose.

Oh, thank you for pointing out my mistake, that means there were two typos in one sentence, then I agree with Demetris that it seems funny for a billion euro project.

Anyway these are minor mistakes, if they can find out the fatal errors in GR.

They are European people, they don't even care to speak English.

Only the people believe in dogmas care about counting typos.

Of cause they know, but do you understand? You cannot even understand that a variable electroweak constant implies the principle of general covariance breaks down in microscopic scale.

Canadian came from everywhere of the world, I was born in China, so who care about English?

You are so stupid to think that modern Chinese still read from right to left or from up to down. Just let you know that I am Canadian, even though I was born in China.

When ancient Chinese had their language, those people going to speak English still were monkeys on trees.

Copycats made a mistake when they learned from ancient Chinese, but they still think that write from left to right as a dogma.

Who still is a monkey even though talking in English?

I was joking to the one who only believe in GR as a dogma, I am sorry if someone misunderstand it.

Please no more off topic comments, thank you for participation.

The detailed discussion is on section 6.2 of my paper posted on RG.

Sigularity can be avoided without CPT violation and without the gravitational repulsive force between matter and anti-matter, The attached theory shows that the repulsive gravitational force can exist when total kinetic energy of a system dominates the total potential energy. A gravitational attractive force can exist in a smaller local system in which total potential energy dominates the total kinetic energy. Because the equation is associated with the reversible process, both forces can be described by same equation. The velocity vector in this equation appear in squared form. So if v is positive or negative, the result is the same. The term particle anti-particle has a different definition in this theory than the term matter anti-matter. The former has opposite velocity and the latter has oposite charge. There is no geometrical singularity in this theory. Space-time are considered imaginary concepts. At planck time when particle anti-particle collide, the total energy of the system would exceed the limit dictated by the compton wavelength which is planck energy and the particle wave would subside. In the absence of particle wave you cannot superimpose any imaginary geometry on it. So this is the state of energy without any oscillations, which we cannot call energy. So I call this the unmanifest which has the property of empty space because it does not interact with other matter. So the unmanifest has no motion and no interaction. It is all pervasive like the empty space and this is the singularity in this theory which has no boundary.

Dear Vikram,

The so-called unmanifest energy in your paper should be the zero point energy of the vacuum.

I have proposed an independent conservation law for field energy in order to solve the so-called vacuum catastrophe problem in section 7 of my paper. Based on the independent conservation law for field energy, fields can transform similar to matters, but will never vanish. We suggest that the field energy could be the energy of spirit or soul, so spirits or souls essentially could be fields. Hence, the pure Higgs field in the perfect vacuum could be the most powerful spirit or soul with the highest field energy density close to Planck energy density. The Higgs field is quite similar to the ineffable Dao, which exists throughout the space forever.  A Chinese philosopher Laozi claimed that the ineffable Dao should be the origin of the universe or could be defined as the mother of everything. Everything has Yin and Yang, and everything comes from Dao, just like the matter and anti-matter comes from the perfect vacuum.

Guoliang Liu: A singularity is not a physical entity, it is only a place where an equation is undefined. Only proponents of black holes and big bangs confound undefined equations with physical reality and thereby reify their undefined equations. Don't worry about Charles Francis - he routinely reifies undefined equations, and is a serial abuser of no consequence.
