It was only 20 years ago , when astronomer discovered that the universe was expanding at an accelerated rate . Without an obvious cause , the conception ofdark energywas introduced . dour zip exerts a force on the universe and is thought to make up 68 per centum of it .
However , there are no accepted candidates for what dark energy is and the disputation about its very existence has raged since its first proposal . A new paper , published in theMonthly Notices of the Royal Astronomical Society , propose that we might not need dark energy after all .
The study , led by researchers at the Eötvös Loránd University in Hungary , suggests that matching precise astronomical observations with the approximated models of the world might have created the need for dreary energy while , in reality , it does n’t exist . In the words of Shakespeare , the demerit is not in our stars but in ourselves .
The different part in the universe of discourse , they believe , expand at unlike rate depending on how matter is stagger there while the cosmos retains an average accelerated expansion . Current standard models do n’t take this into considerateness .
" Einstein ’s equivalence of general relativity that describe the expansion of the world are so complex mathematically , that for a hundred years no solution account for the outcome of cosmic social organization have been witness , ” carbon monoxide - author Dr László Dobos , say in astatement .
“ We know from very precise supernova observations that the universe is accelerating , but at the same time we swear on coarse approximations to Einstein ’s equations which may introduce serious side - effect , such as the need for dark vitality , in the model designed to agree the observational data point . "
To test this the investigator constructed a figurer simulation to compare a standard cosmogonic poser ( with normal matter , glum energy , and the every bit mysterious dark subject ) with one that only had dark topic and normal matter . The requirement was that the latter one , make love as the Avera ( mean Expansion Rate Approximation ) model , has the same critical density as the standard poser .
The simulation show a effective agreement between each other and between the observations both in the early and late universe . The Avera model does actually good match the unmistakable discrepancy betweenthe local and retiring elaboration rates of the universe .
This melodic theme is an challenging increase to the universe enlargement public debate , although it is still too early to tell if it can deal a fateful blow to colored Department of Energy .
