ANTIMATTER SOURCE. “According to the modern concept, primordial black holes can also be sources of positrons and antiprotons.” https://lnkd.in/gDYri97U View in LinkedIn

CLUSTERS. “A globular star cluster is a collection of stars that forms a spherical cluster rotating around the core of the Galaxy. Globular clusters are very closely connected by gravity, which gives them a spherical shape and a relatively high density of stars towards their centers.” https://lnkd.in/gDYri97U View in LinkedIn

ANCIENT FORMATIONS. “Globular clusters are located in the galactic halo and contain more stars and are much older than the less dense open clusters found in the galactic disk. Globular clusters are common, with about 150 globular clusters currently known in the Milky Way.” https://lnkd.in/gDYri97U View in LinkedIn

EXTENDED MIND. “Humans generate and mould their niche (ecological, cultural, and social), and this niche moulds the neural system through the extension of “body schemas” and extra-neural connections. This extreme integration between brain and culture is a key feature in cognitive archaeology.” The landscape imprints itself on the Mind, per William Wordsworth. https://lnkd.in/dhY9QJ5w View in LinkedIn

ANCIENT STRUCTURES. “Globular clusters are the oldest objects in the Galaxy and were among the first clusters of stars.” https://lnkd.in/gDYri97U View in LinkedIn

GREAT DENSITY. “Orbiting the ”outskirts” of a galaxy, globular clusters take several hundred million years to complete one orbit. Stars can reach a density of 100 to 1000 stars per cubic parsec in the center of a globular cluster. This is different from the density of stars around our Sun, which is estimated at about 0.14 stars per cubic parsec.” https://lnkd.in/gDYri97U View in LinkedIn

MINOR NUCLEOSYNTHESIS. “Globular clusters are usually made up of stars that have a low proportion of elements other than hydrogen and helium compared to stars like the Sun.” https://lnkd.in/gDYri97U View in LinkedIn

EXEMPLAR. “The paper considers a typical globular cluster, presumably consisting of anti-stars. As an example, we take one of the closest clusters - M4 in the Messier catalog (NGC 6121 in the new general catalog (NGC)).” https://lnkd.in/gDYri97U View in LinkedIn

M4 ANTISTAR. “Then we also assume that globular cluster M4 is a source of antimatter He4 in galactic cosmic rays.” https://lnkd.in/gDYri97U View in LinkedIn
