The universe can actually be twisted like a giant balloon, a new study claims.
A study published on Monday in the journal Nature Astronomy examines data from the cosmic microwave background (CMB), which is the weak echo of the Big Bang, to conclude that the universe is not flat. The discoveries, however, run counter to the years of conventional wisdom in astronomy.
According to researchers, if the universe is curved, this curve is gentle.
The idea that if you travel far in space beyond our galaxy it moves in a straight line – you will eventually return to where you started – is known as a "closed universe."
Most scientists believe instead the idea of a "flat universe" that extends in all directions and does not rotate by itself.
Researchers claim to have found an anomaly in the CMB, which provides crucial information about the universe. Recent data reportedly indicate that there is significantly more "gravitational objectification" of the CMB than expected, which means that gravity seems to bend the microwaves of the CMB more than the existing physics can explain.
Cosmologist at the University of Rome at Sapienza, Alessandro Melchiori, explained to Live Science that the closed-universe model would raise the ap
"I do not mean to believe in a closed universe," he told Live Science. "I'm a little more neutral. I would say let's wait for the data and what the new data will say. What I believe is that there is a discrepancy now that we need to be careful and try to find what creates this discrepancy. “
