HIGH ENERGY PHYSICS. “During last decade a lot of work has been made for investigation of properties of high energy processes near black holes. This was stimulated by the paper, where it was found that collision of two particles near rapidly rotating black holes can lead to unbounded energies . . in the centre of mass frame.” ""h https://lnkd.in/dqBYwgv View in LinkedIn

“VARIABILITY is a hallmark characteristic of quasars. Nearly all quasars vary across the entire electromagnetic spectrum, with the variability amplitude depending on timescale, wavelength, and accretion parameters (e.g., BH mass and accretion rate). This ubiquitous variability encodes critical information about the structure and dynamics of the emitting regions, as well as detailed underlying physics of accretion and feedback processes in these active SMBHs.” (SMBH = super massive black holes; BH = black hole). https://lnkd.in/dEvc7DF View in LinkedIn

LIFELORE. “Biology derives from the Ancient Greek words of βίος romanized bíos meaning 'life' and -λογία; romanized -logía meaning 'branch of study' or 'to speak'. Those combined make the Greek word βιολογία romanized biología meaning 'biology'. Despite this, the term βιολογία as a whole didn't exist in Ancient Greek. The first to borrow it was the English and French (biologie). Historically there was another term for biology in English, lifelore; it is rarely used today.” https://en.m.wikipedia.org/wiki/Biology View in LinkedIn

GEOMETRIC SPECULATION. “If two particles moving in a straight line directed opposite to each other in the spacetime then they can collide at any point. Collision of the particles occurs close to the outer horizon of the white hole. The second particle emanates from the white hole region should lapse near the bifurcation point but not crosses this point, because if it crosses this point, it would come into the T−region instead of R−region.” https://link.springer.com/chapter/10.1007/978-3-030-51081-7_62 View in LinkedIn

THE FOOTNOTE ANSWER. “The presence of white holes is controversial. Especially, they can be unstable. Several years ago, an interesting speculation was explained which conclude that white holes can act as region retarded in the expansion of surrounded matter in Universe.” https://link.springer.com/chapter/10.1007/978-3-030-51081-7_62 View in LinkedIn

FOOTNOTE OF THE FOOTNOTE. “Since the spacetime of the eternal black hole includes unavoidably two regions; black hole and white hole…the first particle progresses towards the future horizon and second particle accesses the past horizon from the inner white hole region.” https://link.springer.com/chapter/10.1007/978-3-030-51081-7_62 View in LinkedIn
