&gt; Dark matter makes up 95% of the universe now?!?<p>The article was very poorly worded. As @infogulch noted, the 5% is of the total energy content of the universe, not the &quot;matter&quot; content. So that&#x27;s been known.<p>But what seems to be new is that of that 5% of normal (baryonic) matter, we&#x27;ve only been able to account for about half of it (stars, gas in galaxies). These FRB observations claim to have found evidence for the other half of the &quot;missing baryons&quot;, likely in hot gas between galaxies.
