Chinese Scholar Yang Jian liang Putting Wrongs to Rights in Astrophysics

[heyuhua]

Are you trying to negate the conclusion that the universe is expanding? What is your purpose in launching this article?，

Obviously, your understanding of the expansion of the universe is not deep。 Why not base the formation and the evolution of galaxies on the expansion of the universe? Isn't the expansion of the universe the dispersal of galaxies? As I've said, even if there's a merger, it's accidental, and the separation of galaxies is in a dominant position. That is to say, the basic mechanism of galaxy formation can only be gradual growth not merge.

Are you trying to negate the conclusion that the universe is expanding?

You can only say it was expanding in the past...

It may still be expanding and probably is but one need remember everything we look at is coming from the past...the light from M31 only a cosmic stone throw away is 2 million years old (actually it may be 2.5) ... M31 could have disappeared 1 million years ago and we would not know for another 1 or 1.5 million years.

The universe is expanding now, not just in the past, because red shifts are common not only in distant galaxies, but also in nearby galaxies.

The above is a far more accurate - and defensible - position.

And it's what everybody has been telling you all along.

Wow. That took - what? - 400 posts for you to acknowledge?

 

[DaveC426913]

Are you trying to negate the conclusion that the universe is expanding?

No, just your silly novice attempts at cosmology.
No one, in the history of this thread, has denied cosmological expansion.

 

[DaveC426913]

Suddenly you've discovered Doppler shift measures galactic motion!
Well, you've discovered some of it - the red shift part.

Will it take 400 more posts before you acknowledge blue shift?
And then another 400 before you acknowledge that galaxies occasionally collide?

I don't think galaxies really collide, just hypothetically.

 

[heyuhua]

In short, the idea of galaxy amalgamation is pseudoscience, which is untenable both in theory and in practice, and can't stand scrutiny at all, it's actually an illusion to suppose

 

[heyuhua]

Observations show that not only distant galaxies are generally gone, but those near us are also generally leaving.
Why not base the theory of galaxy formation on the expansion of the universe that galaxies are separating from each other? Why do you recognize only the continuous creation of space and not the continuous creation of matter? isn't the continuous expansion of space the continuous creation of space? Why can space be created continuously while matter cannot be created continuously and only was created at the moment of The big bang ?

I think you miss my point....
Everything you look at is from the past...

You literally do not know what is happening out there today, nor can you know, because that light wont reach us until way into the future.

You look out and observe the universe is expanding...that is news from the past...you cant get news of what is happening now...it is impossible as light has a finite speed....if a gallaxy is one billion light years away (in this context it is a distance measurement ... it is how far light travells in one billion years) ...that gallaxy was one billion light years distant when the light we observe today reaches us that light is one billion years old...that gallaxy in real time may be far removed from where we o serve it today...in fact it could have literally disappeared 900,000 years ago as a result of being cleared for a cosmic super highway or all consumed by its central now extremely massive back hole and we will not know until another 100,000 years.

If a supernova went off today in M31 the Andromeda Gallaxy we will not see such an explosion until 2 to 2.5 million years from now...light years is distance but it also means how long it has taken for the light we receive to reach us.

So all our observations show an expanding universe but it literally may have stopped expanding and is contracting...its very important to understand that the light we see shows nothing of what is happening today it shows how it was....the cosmic background radiation is light that is approximately 13.5 billion years old ...we may record it today but it left its source 13.5 billion years ago.

The observations do not show that at all.

Watch my lips...M31 is not moving away it is getting closer...that is a fact...and there are many others that are not moving away...that is a fact...you leave yourself open to be called a fool because you are ignoring facts...go check the facts..Dave left a link...look it up.

[Xelasnave.1947]

Why not base the theory of galaxy formation

Perhaps tell us the way you think it happens and we can all work thru it..but honrestly your stand about no mergers is simply wrong and does not fit the observations.
Remember I said your enthusiasm for new ideas can lead you astray...well before you even try and inject new ideas you really need to understand the facts...mergers happen and have happened and no matter what your ideas are on mattet creation you need to realise those facts are real ...

"You look out and observe the universe is expanding."
What we're seeing in the nearby galaxies is actually what's going on right now，and for the evolution of the universe, hundreds of thousands of years is a moment

Yang's theory holds that not only does the space between galaxies expand according to Hubble's law, but also the galaxy itself is expanding according to Hubble's Law, and new matter is continuously formed in the celestial body.

 

[DaveC426913]

I don't think galaxies really collide...

Science is ambivalent to what you "think".

Facts are facts. A number have been presented in this thread.

Your idea is falsified by direct observation.

Next.

Even if a galaxy looks coming toward us, it does not mean that their average distance from us is decreasing. Like the moon, sometimes it's closer to us and sometimes farther away from us（Perigee and Apogee）, but in the long run, the moon is still away from us, namely 4 cm goes backward a year.

Yang's theory holds that not only does the space between galaxies expand according to Hubble's law, but also the galaxy itself is expanding according to Hubble's Law, and new matter is continuously formed in the celestial body.

On the contrary, observation is negating mainstream theory, and Yang's theory is gradually being confirmed by observation. Mainstream theory is untenable both in theory and in practice

Yang's theory holds that not only does the space between galaxies expand according to Hubble's law, but also the galaxy itself is expanding according to Hubble's Law, and new matter is continuously formed in the celestial body.

 

[heyuhua]

You can think, if galaxies are gradually merged, then each galaxy goes through at least one merger, and the merger in the universe will be dominant, and the conclusion of cosmic expansion will not fail. So the mainstream theory of galaxy formation takes one side off the other and can't be coherent.

Yang's theory holds that not only does the space between galaxies expand according to Hubble's law, but also the galaxy itself is expanding according to Hubble's Law, and new matter is continuously formed in the celestial body.
In Yang's theory, galaxies grow and new matter continues to form in celestial bodies. Today is the initial condition or origin for understanding the past and the future, and the past or the future can be inferred from today.

Look think what you like but I found this ....mindblowing.

You can slander and slander, but what you say doesn't work. Science is always going to progress. It's not your kind of garbage that can stop it. I believe that countless people will gradually accept Yang's new theory。

I'm not slandering one little bit. Your continued ignoring of facts and your continual repeated childish claims are your own doing. Yang's hypothesis will like your hypothesis, simply be lost in cyber space somewhere.

I'm sober. the kind of you are not scholar at all. You're just a fifty-cent party hired by vested interest groups, specialized in undermining new ideas and interfering netizens to form the new common knowledge , and defending the status quo, you can get a bonus from vested interest groups, despicable little men

Yeah that's what most trolls and others with unscientific agendas always say.

In the meantime, science progresses as dictated by the scientific methodology, and that includes the many many mergings of galaxies as per the many links that I and others have given you, and which you in your childishness continue to ignore.

 

[paddoboy]

Let me say again, at the risk of being labeled a hooligan again,..While they may have laughed at Galileo, they also laughed at Bozo the clown. Guess what? You ain't any Galileo.
