Meta_G is the energy of the Metaverse. It was revealed when the Origin StoneKeepers first came across the MetaStones. The Meta_G that was released moved the MetaStones into a unison and the MetaClock came into existence.
How Meta_G can be harnessed in the future is something that the DAO must ponder.
It is believed though that Meta_G is created by all activity in the metaverse and when you look for it coming from any activity, ultimately you can find it. At this point though the only Meta_G ever discovered was at the creation of the Metaclock.
