Dear AhmadLX: As far as is known, dark matter has not yet been found, so its existence cannot be stated, but only assumed, so "should be" is a more appropriate grammatical sentence to define something (such as dark matter) that is not yet discovered. Otherwise, bring sources that say DM "is already" discovered.

Please don't restore this citation to. This is a journal published by Scientific Research Publishing, one of the worst predatory publishers out there, and is not a reliable source. &#32; Headbomb {t · c · p · b} 21:20, 19 January 2021 (UTC)
