In accordance with the virial theorem, half of this unveiled gravitational Power goes into heating, which ends up in a gradual boost in the rate at which fusion happens and therefore a rise in the luminosity. This process quickens given that the core slowly results in being denser.[136] At present, it really is expanding in brightness by about one% each and every one hundred million decades. It will eventually get at least 1 billion yrs from now to deplete liquid drinking water with the Earth from such raise.[137] After that, the Earth will cease to be able to assist elaborate, multicellular daily life and the final remaining multicellular organisms in the world will experience a ultimate, entire mass extinction.[138] Following core hydrogen exhaustion
