====== Negative Mass ======

The idea that some exotic forms of matter might have 'negative mass' was first proposed in the 1950's.

In 2017, a team from Washington State University described an set of experiments which claimed observation of negative mass particles. [[https://www.bbc.co.uk/news/science-environment-39642992|Source : BBC]]

But there is no general agreement about the possible existence of Negative Mass - or what the implications might be. See: [[https://en.wikipedia.org/wiki/Negative_mass|Wikipedia]]

Some proponents of the idea suggest that a universe which contained substantial amounts of 'negative mass' particles might be able to account for the large discrepancies in descriptions of the standard model of the universe - which currently requires [[content:physics:cosmology:dark_matter]] and [[content:physics:cosmology:dark_energy]] in order to explain how the observed universe apparently behaves.
