Dark matter could also explain certain optical illusions that astronomers see in the deep universe. For example, pictures of galaxies that include strange rings and arcs of light could be ...

Observations of the rotation of galaxies, for example, imply that there is a lot of mass out there than we can see. Physicists have been calling this “missing” mass “dark matter.” ...

Outweighing this regular matter five-to-one is dark matter, an invisible substance that doesn’t interact with light. We do not know what this dark matter is, but many labs are looking for it ...

Despite this leap forward for studying microbial metabolites, many molecules remain dark matter for now. The search tool is limited to publicly available metabolomics data, which creates a bottleneck ...

Dark matter holds galaxies and other cosmic structures together ... There are many ways to test different theories for dark energy; for example, we can look at how light is bent around large galaxies ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light and is thus impossible to detect using conventional techniques employed in particle physics. In recent years ...
