A gas made from light becomes easier to compress as you squash it

I wonder what would happen if you used this technique to compress sonoluminescence?<p><a href="https:&#x2F;&#x2F;hackaday.com&#x2F;2019&#x2F;09&#x2F;06&#x2F;capture-a-star-in-a-jar-with-sonoluminescence&#x2F;" rel="nofollow">https:&#x2F;&#x2F;hackaday.com&#x2F;2019&#x2F;09&#x2F;06&#x2F;capture-a-star-in-a-jar-with...</a><p>Which is a fun project you can do at home on your kitchen counter and has mystified scientists since 1934. Some theories suggest it is a fusion reaction and that there is a plasma hotter than the sun forming inside the bubble.<p>I&#x27;m wondering what would happen if they could manage to compress the light as it formed. Maybe it could sustain the light for longer periods of time or increase its intensity? It would probably be difficult to time a sub-nanosecond compression of this kind, though.

My initial reaction: wow, did we find a way to create a mini black-hole? Well, it ain&#x27;t quite a <i>matter-based</i> gas...<p>If it was a gas made of matter, and it became easier to compress the more we compressed it, that&#x27;d be a recipe to create a black hole.. (?)

Any chance of mankind mankind making a pico-scale kugelblitz?<p><a href="https:&#x2F;&#x2F;youtu.be&#x2F;v3hd3AI2CAA" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;v3hd3AI2CAA</a>

So I read the original article about this to some extent, and something just doesn&#x27;t sit right with me.<p>If it becomes &#x27;easier&#x27; to compress as you squash it, I assume there is some level of resistance before they attempt to squash it, right? Something measurable right? Because the more I think about this, the more I want to say &quot;Well of course a photonic gas is easier to squish when applied pressure. It&#x27;s light, it likes to spread out... and fill spaces...&quot;<p>Is that just me? Cause this &#x27;discovery&#x27; feels very much like a 2+2=5 kind of scenario. Something seems wrong. Perhaps its me, but still... can&#x27;t shake this feeling.<p>I don&#x27;t know... Just seems like something is off.

I&#x27;ve once heard that we could theoretically destroy the universe if we just crammed enough photons into a tiny enough space. Would this help?<p>Asking for a friend.
