Thread: What evidence is there for the cosmological dark age?

    I see no reason why the universe would have became cool and uniform then randomly gravity would cause the gas clouds to condense into stars. Why would matter not have started clumping together when it was hot, more densely packed, and lacking magnetic polarity which would only force particles apart? This is assuming that the universe didn't have any antimatter, in which case the idea of a cosmological dark age would only seem more absurd. So what evidence is there for the cosmological dark age?

    Can a moderator move this thread to Astronomy & Cosmology? I seem to have gotten the two confused...

    [Delete please...]

    I read through all of the links you posted thinking there must be some connection to my question. None of them mention the dark age or anything relevant to my question. You've just wasted 30 minutes of my life reading about elementary concepts like cosmic back ground radiation and hubble's law. Do you take me for a fool? It's like you are trying to prove the big bang. If I were really stupid enough to not believe in the big bang, what makes you think posting a bunch of links will change mental retardation? It's apparent you didn't even bother to read anything I wrote. Know it all yob, don't even bother replying because you've already lost all credibility in my eyes, and I won't waste my time reading what you post again.

    Perhaps you overlooked the "anything relevant" in the first link ....

    Therefore, during this period, the universe was effectively opaque. Once the universe had reached 300,000 years old, atoms could form, and electrons were now bound to a nucleus. Once this happened, photons could move about freely. This "first light" is the CMB, and its existence is a very strong indication that the Big Bang occurred.
    and in the third link ....
    What does this mean for our universe (remember 75% of the stuff we can see is hydrogen)? Well, at some point the universe was hot enough that hydrogen was a plasma. At this point, the entire universe was opaque and any light emitted, was immediately re-absorbed by the plasma. However if you wait a little while then the universe will expand and cool. Eventually it will cool enough that this all pervading hydrogen plasma will undergo the transition into neutral hydrogen gas and just as suddenly the entire universe will become transparent. Any light emitted at that precise moment will then travel freely for the rest of the universe's history, not interacting with anything.
    That opaque period is the dark age you refer to.

    And I rather thought the brief descriptions of the circumstances immediately before and after that dark period effectively dealt with your question about why no "clumping". (Reread the sections about plasma to get the logic process going.)

    Your attitude almost put me off answering but ...

    The reasons it didn't start condensing immediately is partly because it was hot: i.e. particles in rapid motion. It took a phase change before it was in a sufficiently cools state to start condensing. But note there was not some instant when gravity "randomly" started to have an effect. There would have always been inhomogeneities, there would have always been gravity. However, these became more significant over time as the universe cooled.

    This might explain a bit more: https://en.wikipedia.org/wiki/Chrono...erse#Dark_Ages

    Structure formation is currently poorly understood but attempts to observe the nature of the dark age universe might help: Cosmic dark ages brought to light - physicsworld.com

    And improved modelling will help. Obviously knowing the nature of dark matter would help as well. And probably understanding dark energy. And whether inflation happened and if so why. And so on.

    Most here probably do. Here's a second opinion: In addition I think you are rude and obnoxious.

    Yes, you are very perceptive for a yob. I've found that in an anonymous community like the internet, trolling is one of the most effective means to acquire the information I seek.

    No, learning is. You ask about one aspect of an idea, but unless you understand the entirety of the idea, you will only be left with more questions.
    Now, that whole 'links' thing is partly my fault. Sometimes I get tired of typing out a long post that may or not be read by some member that has not established themselves, yet. So, instead, I lazily throw some links out there and let the reader choose whether to read or not and I'm out a few seconds instead of thirty minutes.
    The rest is on you and I do not care about whether you like to troll, feel empowered by anonymity or act outrageously offended when you're not pandered to.

    There are plenty of regular people that use forums as a resource for asking genuine questions in order to receive genuine answers and all the trolls always meet the same end.

    Enjoy your stay.

    I would have thought insulting people in your third post and admitting to be a troll are effective ways of pissing people off so they don't want to help you.

    Asking polite questions can be a useful learning tool. You should try it.

    For the time being, I'm going to take this is as a tasteless, humourless attempt at a joke.

    Now with my moderator hat firmly on:

    Being rude, offensive and insulting might be fun for you. Keep it up and you'll learn very little here - because you won't be here. You'll get yourself banned.

    This is a warning.

    the dark age of the universe shouldn't be confused with the time prior to about 380 000 years after the BB. they are two different reasons that the universe was "dark".
    Sometimes it is better not knowing than having an answer that may be wrong.

    Is that some kind of threat? What's to stop me from switching proxies and creating a new account?

    Tehehehee... That was obviously relevant to my question... You really think your guidelines can somehow stop me from creating a new account? Your moderator privileges have no power besides slightly inconveniencing me...

    I think your attitude will give you away pretty quickly.

    You agreed to the rules when you joined the forum. If you have decided you don't want to abide by them now, then just log off and find somewhere more suited to your level of maturity.

    I don't like threats. Go ahead and make some sock puppets. We'll see who gets tired first.

    Actually, as I understand it- a bit of communication with his ISP and they can block him. I don't know if you guys would consider it worth the effort or not...

    It appears someone does not understand what a proxy is... :LOL:
    I understand exactly what a proxy is. That has zero relevance to whether your ISP can block you. It can, fool. It appears you think you know more than you actually know.

    It's as possible that you can mask your trace as much as it's possible that someone can overcome the mask. It certainly won't do a lot of good to argue it, as I wouldn't want to inadvertently tip you off. All of that would probably be more effort than it's worth- You'll probably just get banned a lot.
