Negative matter

Negative matter refers to matter with a mass having an opposite sign of normal matter. As it violates one or more energy conditions, it shows strange properties allowing for the construction of wormholes.

Negative matter is not known to occur in nature and must be artificially created. As wormholes are difficult to keep open for more than a microsecond, negative matter is only limited to a select few civilization that possess the technology to be able to store and handle it.
