Ask Ethan #94: Could dark matter not exist?
Ethan Siegel

Thanks, Ethan. A very informative article. I have only one complaint. ‘…the “acoustic peaks” that simply cannot exist without some form of dark matter.’ Now that doesn’t sound very “scientific” to me. Other explanations of the acoustic peaks can and do exist. But I’ll give you that one since the rest is so well done. It’s just a matter of wording.
