One of the giving puzzler in astronomy is the nature of disconsolate thing and dismal energy . These two portion were aim at different times to explain what we see in the cosmos , but even after ten of research , we still are n’t close to interpret what they are and whether they in truth exist .
Now , a new study suggests a room to get rid of both of them . André Maeder , an honorary professor at the University of Geneva , Switzerland , has proposed go back to the central equations of relativity and Newtonian gravity to receive a agency to abandon the Dark Universe mannikin . His idea is reported in theAstrophysical Journal .
Using this surmisal , the physicist was able-bodied to reproduce the accelerated enlargement of the universe without using dark zip . This explains the move of galaxies within the large galax cluster without claiming that dark-skinned matter exist .
“ In this fashion model , there is a begin surmise that has n’t been take into account , in my thought , ” Maeder said in astatement . “ By that I intend the scale invariability of the empty distance ; in other word , the empty space and its properties do not change following a dilatation or compression . ”
This tweak creates a modest quickening term that can be used to understand features currently excuse by dark matter and dark vigor . For example , it excuse the velocities of cluster galaxies based on visible matter alone . It also explains how star move within galaxies , without the motivation for dark matter . This was actually why Vera Rubin proposed the beingness of such a substance in the first blank space .
The introduction of ordered series invariance understandably can explain feature we find in the universe of discourse , but is it really a nail in the coffin for dreary affair and morose energy ? It ’s not that simple . The surmisal only works for the full and big features since shell invariability can only be found in universal Einstein’s theory of relativity . That ’s because , for Einstein ’s theory , empty space is empty . But empty space is not empty according to quantum mechanism .
In the quantum world , every bit of space - time changes when it ’s distend or compact . in reality , from quantum mechanism , there ’s something called vacuum push that has been linked to dark zip , although the expect values from astronomical observations are unlike from the theoretical quantum ones .
While we still do n’t know what glum topic and dark free energy are , they carry on to be the best theory to explain the cosmos . But more research might severalise us if shell invariability could be a serious contender for the crown .
