This means that at every point in space, the field has two values, density and velocity (1). To me (2), a singularity in a field like this means that one or more of the field values &amp;quot;blows up&amp;quot;, i.e. goes to infinity as you run the time variable forward. But how could this ever happen? The Euler equations model the &amp;quot;conservation&amp;quot; (i.e. constant-ness) of three real physical quantities: mass, momentum, and energy. If these three quantities are finite and constant when you add them up over the whole field, how can any part of…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/2203.17221/"&gt;Paper and discussion history&lt;/a&gt;.
