Whats dark matter
source. Evidence of dark matter first came to the attention of Swiss-American astronomer Fritz Zwicky in the 1930s. Zwicky was studying galaxies’ movements within a cluster called the Coma Cluster. Based on their visible matter, his calculations of their expected speed were wrong; the galaxies were traveling faster than expected.About 23% is made of dark matter and 73% consists of dark energy. The simplest definition of dark matter is that it consists of non-baryonic particles. Dark matter is one form of what physicists call “exotic matter.” Other types of dark matter may exist, potentially with bizarre properties, such as negative mass! References. de Podesta, M ...
