Astrophysical Paradox Problems: An Open Lecture by Professor S.Kuzmenkov
An Open Lecture titled "Astrophysical Paradox Problems" took place on October 10, 2025, at the Faculty of Computer Science, Physics, and Mathematics. The event, held as an online meeting, brought together lecturers and students from Kherson State University (KSU), as well as pupils and educators, particularly from the Kherson Scientific Lyceum.
The lecture was delivered by Serhii Heorhiiovych Kuzmenkov, Professor of the Department of Physics, Doctor of Pedagogical Sciences, Candidate of Physical and Mathematical Sciences, Professor.
During the lecture and the subsequent lively discussion, participants considered a number of fundamental scientific topics and paradoxes, including:
The Paradox of the Moon’s Existence near Earth: Despite the fact that the Sun's gravitational pull on the Moon is more than twice as strong as Earth's pull on the Moon, the Moon remains our planet’s satellite. An explanation was provided as to why this is possible.
The Paradox of the "Close" Moon (The Moon Illusion): The phenomenon of the visual magnification of the Moon on the horizon was discussed. This question touched upon not only geometry but also the psychology of perception.
Why Are We Colder than the Sun?: A paradox related to energy release was considered.
“Frozen Stars” and Black Holes: Serhii H. Kuzmenkov explained why, in the period from 1958 to 1968, the object formed as a result of the gravitational collapse of a star with a mass greater than 20 solar masses was called a “frozen star,” why this name was later abandoned, and why these objects became known as “black holes.”
We are grateful to everyone who joined us!
