Kurzgesagt - In a Nutshell Listen... I realize this is 9 months old so you probably won't see this comment. But 7:04 is literally the DUMBEST THING POSSIBLE. If a single fucking molecule of a Strange mater can essentially destroy an entire planet. Why the fuck would you have that on Earth? Even if it was in a container? All some terrorist or psychopath has do is blow it up and we are all screwed.

This might be a repetitive question but
Can someone please explain or guide on how strange quarks might make strange matter? The video seems to hinge on it.
If strange quarks decay and strange matter is made up of quarks...
