New, contested research suggests our universe may actually be a closed loop instead of a vast, never-ending expanse.
The theory has drawn sharp criticism from other cosmologists.
Confirmation of this theory could completely unravel everything scientists know and understand about our universe.
=================================================================
Imagine jetting out into the universe. You sail past Mars, Neptune, and Pluto, far out past the milky way and into the frothy nothingness of space. What might you find if you travelled far enough?
Well, you might actually end up right back where you started.
There's a small chance the universe may actually be a big loop, a team of researchers report in a new paper published in Nature Astronomy. The scientists—University of Manchester cosmologist Eleonora Di Valentino, Sapienza University of Rome cosmologist Alessandro Melchiorri, and Johns Hopkins University cosmologist Joseph Silk—reanalyzed data from cosmic background radiation—the oldest observable stuff in the universe and left over signals from the Big Bang—and found a puzzling anomaly.
A review of data from the European Space Agency’s Planck Experiment revealed significantly more instances of gravitational lensing of the microwave light that makes up cosmic background radiation than expected. This is particularly puzzling, because scientists aren’t currently able to explain how gravity would be able to bend this much microwave light.
To account for the discrepancy in their calculations, the scientists added a variable, called A_lens, to their model of the universe. But that variable comes out of left field and is difficult to reconcile with known parameters such as Einstein’s theory of general relativity, the scientists admit. And here’s the thing: According to Live Science, the team reached its conclusion with a standard deviation of 3.5 sigma, far below the 5 sigma confidence interval that physicists rely on in order to confirm a theory.
Recently, another paper came to a similar conclusion, but with even less statistical confidence. A paper recently posted to the pre-print server arXiv by University of Cambridge cosmologists George Efstathiou and Steven Gratton, for example, analyzed a smaller portion of the same Planck Collaboration data, and found that evidence for a closed loop system, according to Live Science. When the duo compared their results with other datasets, however, evidence pointed supported a flat, infinite universe.
Confirmation of this theory would pose a massive problem for physicists, and unravel much of what we know about the universe. Only time and more research will help us better understand what shape we’re in.

Who are these people? The earth is flat, and the moon is made of green cheese. Everybody knows that.
And Epstein didn’t kill himself.
I have always thought this.
If you look at a far away galaxy, going AWAY from you,
you should be able to turn around and see it COMING AT YOU!.................

It is called the ‘Al Jolson Effect’.

A closed loop within what? Can’t get around infinity.
There’s a small chance the universe may actually be a big loop,
Our 6 what?..........Film at eleven..........
An abundance of re-greta-bull warmunists and their twins the morons.
I thought “Space is curved” was already well known?
“There be dragons here” was the was the description edges of maps of the early earth, before the explorers learned it was round. What’s the difference?
Will it go ‘round in circles?
Will it fly high like a bird up in the sky?
Think of a Moebius strip.
Now try to think of a three-dimensional version of a Moebius strip.
