WIDE RANGE. “Such PBHs could have masses in a wide range from a fraction of solar mass to thousands solar masses. Of course, there is no noticeable difference between a PBH and an anti-PBH.” (PBH = primordial black holes) https://lnkd.in/d_CXigJS View in LinkedIn

ORIGINS. “Smaller HBBs could form compact stars or antistars. They were created in the very early universe after the QCD phase transition.” (HBB = high baryonic number; QCD = Quark matter or QCD matter (quantum chromodynamic). https://lnkd.in/d_CXigJS View in LinkedIn

ANTIMATTER STARS. “Probably, they can be now observed as peculiar stars in the Galaxy: too old stars, very fast-moving stars, and stars with a highly unusual chemical content.” https://lnkd.in/d_CXigJS View in LinkedIn

ANCIENT ANTISTARS. “The fraction of these strange stars and/or antistars among the stellar population is model-dependent but may be quite high.” https://lnkd.in/d_CXigJS View in LinkedIn

NOT RARE. “The possibility of the existence of a population of antistars in the Galaxy and observational limits on their density were analyzed in several papers. It was concluded that quite a noticeable fraction of antistars is not excluded by the present observations.” https://lnkd.in/d_CXigJS View in LinkedIn

NEARBY ANTISTARS. “Recently, the idea that antistars may be our Galactic neighbors attracted new attention.” https://lnkd.in/d_CXigJS View in LinkedIn

DARK MATTER AND ANTISTARS. “It was suggested that cosmological dark matter could entirely consist of macroscopic antimatter objects, and in ref. [17] a possible indication to antistars in the Galaxy was reported.” https://lnkd.in/d_CXigJS View in LinkedIn

“MEMORIES make us who we are. They shape our understanding of the world and help us to predict what’s coming. To have proper memory function, you have to have forgetting. Forgetting is not a failure of memory, but a function of it. The brain is wired to forget.” https://www.nature.com/articles/d41586-019-02211-5 View in LinkedIn
