    If strangelet can convert stars, we would see many stars converted as we observe through telescopes. We would also see neutron stars with unusually tiny masses. As we don't see these, we can say that hypotesis of this strange matter is highly improbable.

    The idea Strangelets exist is just a theory, its purely a hypothetical particle, and the theory they would breakdown other nearby protons and neutrons and produce more strangelets is just a theory, so this whole video is a theory ontop of a theory ontop of a theory..

    Problem with trying to determine what strange matter is starts firstly with Trying to impose our own understandings of the laws of the universe onto it. When dealing with something is already KNOWN to piss on reality as it is. It is best to approach it by just tossing everything we assume we know out the fucking window to start with before even attempting to try to understand it. if you assume that "it" in our reality will do A-1 all the time. Assume it will do ZQ-8674 More likely every Tuesday in June then The usual A-1 on a February 16th. Humans can be so fucking arrogant in there self imposed belief that everything must match what we so far know about what is "reality'

    Evolves from Charm Quark. This subatomic particle loves to play with other subatomic particles, and hates being apart from them. In some extreme cases, when lonely, they may break apart into other subatomic particles.
