This article is a list of notable unsolved problems in astronomy. Problems may be theoretical or experimental. Theoretical problems result from inability of current theories to explain observed phenomena or experimental results. Experimental problems result from inability to test or investigate a proposed theory.
Igor Bogdanov (left) and Grichka Bogdanov (right) in 2016. The Bogdanov affair was an academic dispute over the legitimacy of the doctoral degrees obtained by French twins Igor and Grichka Bogdanov [1] (usually spelled Bogdanoff in French language publications) and a series of theoretical physics papers written by them in order to obtain degrees.
Acupuncture has been the subject of active scientific research since the late 20th century and its effects and application remain controversial among medical researchers and clinicians. Some scholarly reviews conclude that acupuncture's effects are mainly attributable to the placebo effect and others find likelihood of efficacy for particular ...
Riess shared the 2011 Nobel Prize in Physics for the discovery.) [12] Filippenko was elected to the California Academy of Sciences in 1999, [13] the National Academy of Sciences [14] in 2009, and the American Academy of Arts and Sciences in 2015. [15] In 2021 he was elected as a Fellow of the American Astronomical Society.
Some parts of astronomy education overlap with physics education, however, astronomy education has its own arenas, practitioners, journals, and research. This can be demonstrated in the identified 20-year lag between the emergence of AER and physics education research. [3]
Theoretical astronomy is the use of analytical and computational models based on principles from physics and chemistry to describe and explain astronomical objects and astronomical phenomena. Theorists in astronomy endeavor to create theoretical models and from the results predict observational consequences of those models.
As described above, individuals have their opinions based on various subjects such as culture, history, ethics, morals, religion, and more. This leads the stance on certain scientific topics to be very different across the board as perceptions vary from person to person, this is the ultimate reason why scientific controversy exists, to begin with.
The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.
