    None of those are angry. I'm just blunt- I talk straight and say what I think. It may be unrestrained, at times, but those were not said angrily.

    Thanks for clearing that up. You can be blunt to me and i would like you to keep explaining/justifying your answers. Just be cautious with new member not to come off as argumentative without having a proper reason. Everyone has a right to their opinion, u can disagree and try to prove them wrong. But even the dude who thought the earth was flat had some sort of reasoning and science behind it all. He was of course wrong, and as technology advances so will science. What we think today may one day be proven wrong. So dont forget to challenge everything. Knowing like you said science is not 100% accurate all the time. Keep an open mind tks.

    Back to the topic. Do you disagree with the articles i posted if so y?

    Could dark matter and energy not exist?

    Could they have been made up in order to make necessary calculations make sence?

    Also in regard to the last article i posted.
    Could galaxies have some sort of ties, causing them to move and orbit a centralized point; or themselves together in synchronization?

    I haven't had a chance to read your articles, yet. When I get to it, I'll make a meaningful reply.
    On these questions: Could Dark Matter, Dark Energy be wrong?
    Of course.
    They are hypothetical and used to show that we think "something is there, even if we don't know what it is."
    Yes, they are supposed, hypothesized, guessed as to what they are. Saying they are "made up to make necessary calculations make sense" is about as accurate a statement as any. There's a bit more to it than that... and PopSci articles don't really go into that kind of depth. But... close enough for a science discussion board, right?
    We do not know if there is any kind of Dark matter or not. We think there may be and so we have models and proposals for testing. The hypotheses are currently untested. They could be wrong.

    All it is is that for right now, these are the models we have that have the most evidence to support them. The big Bang Theory has a lot of strong evidence. But the Dark Matter Model... has weaker evidence.
    Dark Energy model has pretty strong evidence, but the mechanism could be something different than what we may have considered or proposed. Unlike theory, these are hypothetical models and we are all aware that they are a bit tenuous.

    I'll read the links you posted later... I usually shun PopSci style articles because they are full of sensationalism but lean on information. I had maybe ten minutes to spare at the moment.

    All good bro, whenever u decide to read some proof bro, its all good ��. )

    These articles are not "proof." They are articles that discuss some possible models.
    What an interesting methodology you must use in order to reach conclusions about the world... While proofs exist in mathematics, science does not work in proofs. I have repeatedly explained to you how the scientific method operates. Maybe we need to make a thread where we can hash out the differences between "evidence" and "proof" and what they mean.

    I've have read through three of them and cross referenced them to other material, so far.
    The peer reviewed journal entry on McGaugh's teams work can be found here:
    https://arxiv.org/pdf/1609.05917v1.pdf
    While it is not "proof," it is evidence and well presented evidence at that. It certainly warrants further study and hey, it may be a strong candidate to replace the Dark matter Model.
    McGaugh's model presents the following:
    -It is quite simple and direct. It follows mathematically and logically. Occams razor.
    -It is independent. It requires no unknown outside forces.
    -The data is supplied by MOND, Spitzer and many other reliable sources.
    -The data matches plotting points closely and is independently verifiable.

    The problems include:
    -Limited data; the data used to model these systems is significantly less than current models; too soon to jump to a conclusion.
    -It does not match current galaxy formation models; this is to be expected, however. But the data needs to be correlated against standard model data, heavily, in order to suss out data problems.

    A likable candidate.
