A last year’s study brought some other perspectives for a group of astronomers, which started to determine if the Universe is curved and close, similar sphere. They based their new research on data from ESA’s Planck satellite. The team of astronomers led by Eleonora Di Valentino from Manchester University in the UK came up with some insights which present a “cosmological crisis.” Their research also needed a “drastic rethinking of the current cosmological concordance model.”
According to them, the fact that indicates the Universe’s curvature is present in the way gravity deflects the path of light. Moreover, this a point that is based upon an effect foretold by Einstein known as gravitational lensing. The path of light, however, represents the actual CMB (cosmic microwave background); also, it is the electromagnetic radiation remained in the outer space between the galaxies and the stars, 380,00 years after the Big Band, at the moment when Universe’s first neutral atoms developed. It is, too, the oldest light in the Universe.
The Planck satellite offered data that indicates the CMB is more powerful gravitationally lensed that the astronomers knew it was. Planck Collaboration titles this issue “Alens,” and is set to be solved. Astronomers, on the other hand, think the shape of the Universe could be a reason. They stated, “A closed Universe can provide a physical explanation for this effect, with the Planck cosmic microwave background spectra now preferring a positive curvature at more than the 99 percent confidence level.” Also, they started a close examination of the evidence for a closed Universe from Planck to release an official statement and reason, too.
Except for the “Aliens” anomaly, the rest of the data supports the idea of a flat Universe, meaning that until new research, we’ll have to wait a little bit more. The team detailed, “Future measurements are needed to clarify whether the observed discordances are due to undetected systematics, or to new physics or simply are a statistical fluctuation.”
