For years scientists have believed our universe was as flat as a piece of paper, but new evidence has suggested it’s curved like a giant inflated balloon. The latest study analyzed data from the cosmic microwave background, the faint echo of the Big Bang, and discovered gravity seems to bend the microwaves.
These findings level in the direction of a closed universe – the concept in case you journey far sufficient into space, you’ll loop again around to the place you began. In the paper, printed in Nature Astronomy, researchers famous the 2018 Plant Legacy release that confirmed the presence of ‘gravitational lensing’ in cosmic microwave background (CMB), which suggests its microwaves bend.
The CMB is the oldest thing discovered within the universe, and it’s made up of ambient microwave light. ‘A closed Universe can present a bodily rationalization for this impact, with the Planck cosmic microwave background spectra now preferring a constructive curvature at greater than the 99% confidence stage,’ reads the research.
These findings contradict years of ‘standard knowledge and different research primarily based on the identical CMB knowledge set’. And the speculation of a flat universe may very well be ‘masking a cosmological crisis the place disparate noticed properties of the Universe appear to be mutually inconsistent’, the authors write.
Sapienza College of Rome cosmologist Alessandro Melchiorri, who’s concerned within the current research, defined to Stay Science that the closed-universe model would elevate a variety of issues for the field of physics.
Though the 2018 Plant Legacy launch is confirming the closed universe with 99.8 percent accuracy, the researchers nonetheless famous that ‘future measurements are wanted to make clear whether or not the noticed discordances are attributable to undetected systematics, or to new physics or just are a statistical fluctuation’.
