THE PURPOSE OF LIFE? “Organisms have been selected for two properties: rapid reproduction in optimal conditions and the ability to survive rarely encountered extreme conditions.” The famous Cambridge astronomer Fred Hoyle was horrified that this could be biology’s answer to the meaning of life. https://www.nature.com/articles/35011540 View in LinkedIn

THE WORST PLAGUE. “A fleck of strange matter traveling fast enough could enter a star or a planet, changing it from the inside out, growing like a bacterial culture that continues to eat. This is one of the most sensational pictures of Earth’s death: the planet struck by and devoured by an unstoppable flood of strange matter. It’s the reason some call strange matter “the most dangerous substance in the universe”. https://lnkd.in/dj52j3n View in LinkedIn

VAPORIZATION. “In principle, strange matter should be heavier and more stable than normal matter. Moreover, it might even be capable of converting ordinary matter it encounters into more strange matter. Previous research suggested that a strange quark star that occasionally spurts out strange matter could quickly convert a neutron star orbiting it in a binary system into a strange quark star in just 1 millisecond to 1 second.” https://lnkd.in/dhCeUnA View in LinkedIn

DO NOT LET THIS IMAGE GO. “As neutrons and protons bleed into the strange matter and morph into the buzzing quark bath, any freed energy will work to further convert more matter into strange matter.” https://lnkd.in/dj52j3n View in LinkedIn

LOWEST ENERGY STATE. “A neutron enters strange matter and dissolves to release its quarks, lowering its energy. This lower energy state is more stable — possibly the most stable energy source in the entire universe.” https://lnkd.in/dj52j3n View in LinkedIn

LABILE. “But strange matter from just after the Big Bang could not have survived up until now. When scientists take into account the early conditions of the universe, thermodynamics, and the expected properties of strange matter, analyses show time and again that strange matter would have evaporated as conditions cooled, lasting until only a second after the Big Bang explosion. This evaporation is also the main reason why strange matter doesn’t make a convincing dark matter candidate.” https://lnkd.in/dj52j3n View in LinkedIn

NEUTRONIUM. “Ordinary neutron stars should have a fluid made almost entirely of neutrons beneath the crust. This is neutronium, a mysterious and extremely dense substance. Just a spoonful of it would weigh more than Earth’s tallest mountain. But this neutronium doesn’t exist just anywhere — it exists at the center of a neutron star where immense pressures can cause the neutrons to melt into quarks. Neutrons are not, after all, elementary particles. Quarks are.” https://lnkd.in/dj52j3n View in LinkedIn

INPUT-OUTPUT BIOLOGY. “The history of life can be described as the evolution of systems that manipulate one set of symbols representing inputs into another set of symbols that represent outputs.” https://www.nature.com/articles/35011540 View in LinkedIn

COSMOS INFIRMA. “Very little is known about the interior of neutron stars, but there is evidence that strange matter may lie just beneath the thin crust of ions, electrons, and gas. Some hypotheses suggest that there may not even be such a thing as neutron stars and that every object we suspect to be a neutron star is actually a strange star.” https://lnkd.in/dj52j3n View in LinkedIn
