Chinese Scholar Yang Jian liang Putting Wrongs to Rights in Astrophysics

In the natural unit, light speed c=1, the pressure and density can be added up directly, so dm=-pdv, of course, in the international unit, it's -pdv=ccdm.

here my discussion is in the natural unit， namely c=1

dimensions of pressure is F/L² = FL/L³=energy / volume=dimensions of density of energy, in natural unit density of energy =density of matter, so the pressure and density can be added up directly. F is force and L is length

In that case your formula must still include a c² factor to make sense, dimensionally. This is not an issue of units, it is an issue of dimensions.

Like with E=mc²: if you leave the c² out it becomes E=m, which is nonsense regardless of what system of units you are using.

in natural unit light speed c=1,E=mc²=m is correct, do you doubt it? If you don't understand this, you must not learn physics well. please see any textbook, it's not a problem and is not worth discussing.

 

Very funny.

Aha, I had no idea this was a recycled piece of nonsense. As you can perhaps imagine, I have not read all the way through this interminable rubbish.

The poster seems to be a sort of Chinese version of Reiku - even so far as both of them revealing their real identities, via citing their nonsense "papers".

 

Don't worry, you're not missing much.

One difference is that this poster has a higher conspiracy-nut content. I, for example, have apparently been proved to be a shill, out to stop scientific progress.

There's nothing else to say, you just have to remember Yang's theory: Expansion of galaxies is in equal proportion with the expansion of space, which has been verified by Cristina Martínez-Lombilla's recent observation. There will be more and more observations in the future to prove that Yang's theory is revolutionary truth. The progress of science can't be stopped by anyone。

 

Yang's theory not only does not reject the supernova's explosion, but also gives the reasonable mechanism of the supernova's explosion for the first time: an explosion occurs when matter or energy inside a star gradually increases or accumulates to a critical point, for example, earthquakes are an explosive phenomenon, namely when the earth's material or energy gradually accumulates to a certain extent inside it, it will break apart. This is the real mechanism of the earthquake, not the result of plates' movement. Yang's theory classifies stellar eruptions and earthquakes as the same cause， which is a big step forward.. According to Yang's theory, not only does the space between galaxies expand according to Hubble's Law, but also the galaxy itself expands according to Hubble's Law, and new matter or energy is generated continuously in the celestial body, and Events such as earthquakes and eruptions occur when matter or energy accumulates to a certain extent, which justifies why the sun is getting brighter and the stars erupting.The explanation of stellar burst in previous theories is far-fetched, can not rationally explain why the sun is getting bigger and brighter.Yang's theory has been indisputably confirmed by the latest observations, Cristina Martínez-Lombilla's recent observation shows that the Milky way's radius is expanding at a rate of 500 meters per second, in full agreement with Yang's theory, which proves that galaxies form from gradual growing, and forcefully denies old theory of galaxy formation that galaxy formation are a course of an accumulation of existing matter. Only by using Yang's theory can we really explain such the expansion of galaxies，only Yang's theory can link the formation of galaxies to today's their behavior, the previous theory of galaxy formation was not based on actual observations, but rather fabricated

 

In Yang's theory, stars are transformed from planets. As the mass of a planet grows, its temperature rises and it glows gradually, turning into a star. Of course, the planets evolved from smaller dust. For example, after a certain period of time, both the Earth and the moon may become stars. In short, everything came from a gradual change, and in cosmology must fully embody uniformitarianism rather than catastrophism, because the universe is essentially slow to change, and even rapid changes like eruptions are the result of accumulations of slow change. The past and the future of the universe must be understood in terms of its present behavior, rather than judging what it was like by guessing what it was like. The fact that galaxies are expanding today suggests that galaxies come from gradual growth rather than accumulation of existent matter, and the process is not over and is still going on. At the time of the Big Bang the mass of all galaxies and celestial bodies was zero, so there was no singular point of infinite density and infinite temperature, and the density of the universe remained constant in yang's theory. The Big Bang is the simultaneous production of space and matter, and the process is never over. At the Big Bang, it just went faster.Unlike previous Big Bang theory, where matter is produced instantaneously, space can expand or continue to produce besides the time of Big Bang.

 

You are aware that that recent observation is also compatible with current mainstream theories, and thus does nothing with respect to rejecting the null hypothesis?

 

The current observation that the galactic radius is expanding at a speed of 500 meters per second can only be the result of the expansion of the galaxy as a whole, not the result of the absorption of foreign matter，which is the only reasonable explanation. That is to say, the galactic radius is expanding at a speed of 500 meters per second, not the motion of matter in existing space, but the expansion effect of the whole.

 

This means that matter is created continuously in celestial bodies, otherwise, as time goes backward, all matter must be compressed together, and it is impossible to appear today's spiral arm.

 

From the press release you linked in your own post:
"Some star-forming regions are found at the outer edge of the disc, and models of galaxy formation predict that the new stars will slowly increase the size of the galaxy they reside in."

So your own source demonstrates that you are wrong.

 

You're wrong. You're not good at thinking.
The radius of the galaxy expands at a speed of 500 meters per second, and it cannot be the velocity at which foreign matter accumulates. This speed is equivalent to the speed of a bullet, even if there is an invasion of foreign matter, there can be no such a high speed，it's even less possible to just land on the edge, should fall anywhere on the disk, and the disk-shaped structure must be destroyed. So the expansion rate of the galaxy radius can only be the result of the whole expansion. The larger the galaxy, the bigger the expansion velocity of the radius, which can be measure further. In Yang's theory, new stars are transformed from planets, and planets grow in mass, temperature rises, begin light, and become stars gradually. Current star formation theory believes that stars were the result of mass accumulation. In fact, if they were the result of mass accumulation, the accumulation would have long ended and could not last until today, At the time of the Big Bang, they were closest to each other, and they were actually in a state of aggregation, so why did they spread out by the state of aggregation and then gather again? logically, it didn't work.
The so-called interstellar gas is not a gas made of molecules, but a celestial body of different sizes

 

No, you're not good at reading. Let me repeat the quote, highlighting the relevant bit:
"Some star-forming regions are found at the outer edge of the disc, and models of galaxy formation predict that the new stars will slowly increase the size of the galaxy they reside in."
What models would that be? It sure as heck ain't yours, because they would've mentioned that. No, that refers to the current mainstream models, predicting galaxy growth. In other words, this observation is compatible with current mainstream theories. In fact, when you read the press release (and your copy-pasted text) more closely, you'll find out the entire reason this team went looking for galaxy growth is because it is predicted by mainstream models!

 

You are wrong. "models of galaxy formation predict that the new stars will slowly increase the size of the galaxy they reside in.", this is about galaxies absorbing foreign matter and galaxies grow slightly. But by absorbing foreign matter, it's impossible to expand the radius of the galaxy by 500 meters per second, which is the velocity of a bullet, and it's only the result of a global expansion.In fact, if foreign material accumulates at this rate on the edge, then the rest of the disk should pile up at that rate, galaxies can only be spherical，real galaxies are obviously not the case. In short, the expansion of the galaxy radius at a speed of 500 metres per second can only be explained as the result of the expansion of the galaxy as a whole, and any other explanation is unreasonable.

Your nonsense is in pseudscience, will be in psudoscience tomorrow, next year and in the foreseeable future, until thankfully eventually lost in cyber space, where all pseudoscience eventually ends up.

 

You are extremely wrong, don't talk nonsense. Yang's theory is a scientific truth, which has been confirmed by the latest observations and will certainly replace the old doctrine. No matter how insulting you may be, the truth is invincible
