A serial ofnew papersis prepare to invigorate a major debate in cosmogeny . You see , for a few years now , the field has been deal with a severe crisis . Different overture to measure the expansion pace of the Universe ended up with different values . This has profound consequences on our understanding of the Universe in general . It can also be understood in a more square room : the geezerhood of the cosmos is estimated from the measured expansion rate .
So on one hand , we have the measure from Cosmic Microwave Background ( CMB ) from the European Space Agency ’s Planck mission . This cast the age of the world at 13.78 billion years old . But measurements from the motion of galaxies suggest that the universe of discourse is flesh out quicker , making it century of trillion of years younger .
The new study , published in theJournal of Cosmology and Astroparticle Physics , reports on the observations from Atacama Cosmology Telescope ( ACT ) . This official document also study the CMB , the afterglow of the Big Bang . The old age measurement they made is 13.77 billion years one-time – plus or minus 40 million age – well in agreement with Planck .
" Now we ’ve fall up with an answer where Planck and ACT agree,“Simone Aiola , a researcher at the Flatiron Institute ’s Center for Computational Astrophysics and first author of one of the document , say in astatement . " It speaks to the fact that these unmanageable measuring are dependable . "
While it was regard very unlikely , there has been word that maybe that the tension between the two ways to measure the expansion charge per unit was due to an error somewhere in the Planck observations or data . The result , independently obtained , shows that this is not the guinea pig . There must be something new to turn over in our cosmogony .
“ The growing tension between these distant versus local measurement of the Hubble invariable suggests that we may be on the sceptre of a young find in cosmology that could alter our reason of how the Universe work . It also highlights the importance of improving our measurements of the CMB with ACT as well as the future Simons Observatory and CCAT - prime projects that we are now work up , ” said co - authorMichael Niemack , associate prof of physics and astronomy .
New measurements of the enlargement rate of the world are have a bun in the oven using forthcoming lookout station . Researchers have even suggested the use of gravitational waves to probe the universe in a completely dissimilar mode . While the tension is certainly not ideal , it is also an exciting time for cosmogony . A more exact understanding of the universe could be just around the turning point .
