collapsed interstellar clouds

This is all now just low entertainment at the expense of MT and to a lesser degree, Anom. Getting kinda boring.

You are correct. Here are some facts. They may be equally boring, but they are facts.

Interstellar Gas Clouds

1. From Water Abundance in Molecular Cloud Cores: http://www.journals.uchicago.edu/ApJ/journal/issues/ApJL/v539n2/005259/005259.web.pdf
a) Cold clouds (temperatures as low as 10K-30K) may have only a few parts per billion water vapour.
b) Hot clouds, warmed by nearby young stars may contain 10,000 times more water.
c) The formation of water in such star nurseries may cool the clouds, promoting further star formation

2. From http://www.space.com/scienceastronomy/astronomy/galactic_clouds_991123.html, summarising three papers in Nature 402 Nov 25 1999
There are high velocity clouds moving in the galactic halo. These likely have multiple origins:
a) Primordial remnants of the formation of the Milky Way.
b)Bilked leftovers of dwarf galaxies that got too close to the Milky Way.
c) Fountains of stuff formerly spewed by supernovas from within the Milky Way.

3. The dominant element in all these clouds, naturally, is hydrogen.
http://cosmos.swin.edu.au/entries/interstellargascloud/interstellargascloud.html
a) Only the coldest clouds contain molecular hydrogen. These are also rich in dust. These are the Giant Molecular Clouds.
b) Where the temperature is a little higher, around 100 K, the hydrogen dissociates into neutral hyrdogen atoms. These are the HI clouds.
c) In the region of hot stars the clouds may heat up to 10,000 K, ionising the hydrogen. These are the HII regions.

4. And those vaguely familiar with the Virial theorem relating to cloud collapse may find this link useful. http://www.go.ednet.ns.ca/~larry/stars/collapse.html
It includes a worked example of a collapsing cloud - diameter: 50 light years; mass: 330,000 x Sun

I find all things astronomy to be fascinating.

MT, I skimmed through your proposal, and there is nothing there. I have a degree in astrophysics and have done research in star formation, and your work is entirely composed of cute drawings and incomprehensible techno-babble. You will claim that, because nobody can understand what you wrote, it is therefore an invincible theory. Unfortunately, this compounds the evidence that you know nothing about the scientific process. The goal of technical writing is to express, in simple, direct language, exactly what your work is about, not to obscure it with inpenetrable writing. One does not understand a theory until one can express it clearly to someone who has no background in the subject and make them understand it. Since your work cannot be understood even by intelligent people, it seems that you have failed this crucial step.

Best of luck with your work, but you need to learn how to write, and learn some physics to back up the ideas. Cartoons are not science. Including pi (NOT Pie, as you spelled it in the papers), and tossing out the names of famous scientists does not make something science.

And, just out of curiosity, could you define this "quality of Pie" that the externally applied energy supposedly has? I sincerely hope it has nothing to do with the famous Sagan quote: "To bake an apple pie from scratch, you must first create the universe."

 

And I remember U arguing with valid points over it, but now I cant find them again in this thread.

 

Nova1021, your post was a delight of economy, accuracy and focus. Thank you.

 

Just to answer the question of the OP with precise ciphers, the Solar Nebula, i.e, the molecular cloud that gave birth to the Solar System, had a radius of 50 AU. In comparison, the radius of the orbit of Pluto is 40 AU. Curiously, our Solar System is actually much bigger than that, because the (hypothetical) Oort Cloud has an outer radius of 100000 AU. The Oort Cloud objects were formed much closer to the Sun than their actual abode, but were ejected to their actual orbits

 

So do U think the hydrogen the first of the elements in the universe just collapsed into stars instead of expanding out into space being pure gas molecules ? And that too when the universe was very very hot.

 

Yes.

 

But take into account that this hydrogen was not distributed homogenously, but was more dense in some zones that in others. It's pure gravity: the more denser zones collapsed to form stars

 

So By that defination there should be no BigBang At all Or in the first few seconds after BigBang the universe should become a single gaint star and hence a single Blackhole.

 

Matter didn't form instantly "at the big bang", it appeared shortly after.

Must've been those despicable human moderators, eh Anomy?

 

Hey Nova 1021, excellent post.

 

So it formed after a while so as not to collapse but yet it did not fly off into nothingness, instead it formed into universe, how unbelievable.

 

was all matter at a super high temp when it formed??? IN BIG BANG???

and does that temp relate to velocity???

and is not this heated gas.. in an expanding volume???

well... science tells us.... a heated gas will always expand to fill its container...

not condense to form clouds..

unless the atoms can cool....

so how did they cool??

i.e.. slow down.. in their exspansive motion?

Form what U said I think there was no BB instead there must have been a

Big Lump

 

The cooling wont do anything to the speed , infact the universe is in acceleration expansion, that tells me that at some point acceleration musta been zero, hence there was a LUMP and not a explosion.

 

The Big Bang theory (note: that's a scientific theory, make sure you understand what that means: http://en.wikipedia.org/wiki/Theory) says that the universe began with a period of rapid expansion and "cooling". It is important to remember that this is not like a gas expanding to fill its container. The universe is the container and it was simply expanding. It wasn't that space was empty blackness, and all of a sudden there was a huge explosion. Space itself was created with the big bang. This is a very important concept to wrap your mind around.

The second important concept is that there was no distinction between matter and energy when the big bang occurred. By Einstien's famous equation energy can be related to mass by the speed of light (E-MC^2), so energy and mass are the same thing. At the instant after the big bang, there was just energy. As the universe expanded, the energy density dropped enough so that particles started to form out of the energy. Then the particles began to interact to form larger particles. Quarks formed protons and neutrons. Protons and neutrons began to stick together into helium and lithium.

This soup of particles cooled because, as you say, the volume they were in was expanding. If you've ever used an aerosol spray can you get some idea of what I mean. As the gas expands into a much greater volume (the space outside the can) it gets cold. Frost can even form on the can. Similar idea with the universe, except the gas isnt leaving its container, the container is just getting bigger. You have a very hot gas in a small volume, but that volume is expanding, so the gas cools down. It's called adiabatic expansion, look it up.

Eventually, the universe cooled enough that the electrons could bind to the nuclei flying around, and form atoms. When this happened, the universe suddenly was no longer "opaque." That is - electromagnetic radiation could travel without being instantly absorbed by the charged paticles flying around. That radiation is still traveling through the universe today. It's called the cosmic microwave background.

Slight variations in the density of this cloud of atoms caused gravity to start to pull them into clumps. Those clumps collapsed and formed galaxies. A similar collapse process occured in the galaxies to form stars, and around the stars to form planets, and around some planets to form moons.

 

EXPANDING AND COOLING.. and lumps... i see.

one question...

this cooling... where does the heat go?


OH AND BY THE WAY.... a gas in an expanding volume will always obsorb energy....
that why it causes cooling...

the gas itself... in the exspansin process is actually obsorning energy... heating up.


so again... where does the heat go?? outside our space..??????

it must convert to something... and photons.. again.. will all be expanding and spreading.... not condensing.

but please.. explain..

1) where heat go?
2) do gas obosrb heat in expansion? yes they do.

-MT

 

The heat goes into empty space as IR radiation I think.
