Last year , Professor Richard Lieu proposed that there could be gravity happening evenwithout mass . This proposal , outside the schematic understanding of cathartic , was to explain the effects of dark matter anddark energy , two hypothetical feature that are at the base of thestandard model of cosmogeny . Despite their importance , we have not found them ; some people suggest that mayhap they do not exist , and the error is in our misinterpretation of what in reality does exist .
Lieu now has a follow - up marriage proposal that seems even more dramatic . Dropping the possibility of negative masses and negative densities , the professor suggests the creation of transient temporal singularity : mini Big - Bang - like events that can flood the universe with thing and energy , vanish just as quick as they form .
“ This new paper purport an improved version of the earliest role model , which is also radically different , ” Lieu , a purgative professor at The University of Alabama in Huntsville , said in astatement . “ The new model can account for both social system formation and stability , and the central observational properties of the expansion of the population at enceinte , by enlisting density singularity in time that uniformly affect all distance to replace conventional dark issue and dreary zip . ”
The mien of these singularity would act likedark matteracts , adding an invisible amount of matter , five time the amount of regular matter that we know off . They would also exercise a negatively charged pressure , just like dark energy does , pushing the existence into an accelerated enlargement .
“ In the current hypothesis , the conjecture is for matter and vigour to seem and go away in sudden bursts and , interestingly enough , there is no violation of conservation laws . These singularity are unobservable because they occur rarely in time and are unresolvedly fast , and that could be the reason why dark matter and dark energy have not been obtain . The origin of these temporal singularities is unknown – safe to say that the same is true of the moment of the Big Bang itself . ”
sullen matter and dismal energy are far from a perfect theory so it is good that they arechallenged . Still , there are points of Lieu ’s idea that are unmanageable to square with observations , like the world of galaxies with less dark affair or more than the average . Also , we involve testable prediction . If we ca n’t see them because they come along and vanish , is there another way to prove their existence ?
The study is issue in the journalClassical and Quantum Gravity .
