You may be aware of the fact that for years now, experts used to believe that the universe is flat, but now, new evidence is suggesting that it’s actually curved like a massively inflated balloon.
A new study hints that gravity is bending microwaves
A new study analyzed data coming from the cosmic microwave background, the echo of the Big Bang, and it’s been revealed that gravity seems to be bending the microwaves.
This discovery shows that there are definitely hints of a closed universe and this involves the idea that if someone travels far enough into space, they will loop back around to where they started.
Daily Mail reveals that the paper has been published in Nature Astronomy and in it, experts highlighted the 2018 Plant Legacy release that confirmed the presence of “gravitational lensing” in cosmic microwave background (CMB) – this suggests its microwaves bend.
Just in case you don’t know, the CMB is the oldest thing that is found in the universe, and it’s basically made up of ambient microwave light.
According to the official notes that can be found in the study it seems that “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% confidence level.”
The discovery contradicts what other studies revealed so far
It’s also worth noting that these findings are strongly contradicting what it was believed so far and what other studies have hinted at.
The online publication mentioned above noted that cosmologist Alessandro Melchiorri, who was a part of this recent study told Live Science that the closed-universe model poses various problems for the field of physics.
“I don’t want to say that I believe in a closed universe. I’m a little bit more neutral. I’d say, let’s wait on the data and what the new data will say,” he said.
He continued and told Live Science that “What I believe is that there’s a discrepancy now, that we have to be careful and try to find what is producing this discrepancy.”
