The discussion centers around the existence of the Nemesis star, a hypothesized companion to the Sun. Participants explore various aspects of this concept, including its potential detection, historical context, and implications for stellar formation. The conversation touches on theoretical, conceptual, and historical dimensions of the topic.
Participants generally disagree on the existence of the Nemesis star, with some viewing it as a plausible concept and others dismissing it as unlikely or obsolete. The discussion remains unresolved, with multiple competing views presented.
Some claims about the historical context of the Nemesis hypothesis and its current standing in the scientific community are based on interpretations of external sources, which may not reflect a consensus among scientists.
Indeed. Stellar nurseries often form dozens, hundreds, or thousands of stars in a confined area. It would be no surprise if the Sun had a close companion that was lost shortly after formation. Open star clusters, which is where the Sun likely formed, tend to 'disintegrate' over time.Jupiter60 said:I just had a look at the Wikipedia article on Nemesis. It says that in 2017 that some scientist said that thought that the Sun may have had a companion star in the past, but it left the Solar System more than 4 billion years ago. This is a possibility. The reason why we would not be able to detect the historical companion star is because it is no longer a companion star, but got separated.
