New Research Suggests the Universe May Be a Giant Loop

==================================================================

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.

I like to tell high school kids this: If you travel at the speed of light, from your perspective, you are everywhere in the universe at once. Further, the light from a star 100 million light years away occupies every single point between the viewer and the star. And every point of light in that straight line is everywhere in the universe at once. And the light from that star is on an infinite number of “lines” in the sphere of light it gives off.

And God is light.

> our universe may actually be a closed loop <

Based on an exhaustive study of what’s in my cereal bowl, I believe that the universe is not one loop, but many multi-colored loops. I have already applied for a federal grant to investigate this further.

Looking more and more like we really live in a simulation.

The idea is not new. If you kept going, and going, there is no edge of the Universe to come to. So what happens? You don’t disappear. You eventually arrive at your starting point.

Sees odd that calculations that don’t come out as expected could trigger a complete revision of the theory of the Universe.

They don’t even know if the Universe is finite or infinite. Resolve that question and then you can move on to other important questions.

It is either infinitely finite or finitely infinite..............

Probably more of a Mobius strip.

As a child, I tried to conceptualize a God before time, eternity, and a universe without end....not ashamed to say my head couldn’t grasp it....newer theories make my head spin faster than a neutron star...or even a black hole (if they still exist)....

Now try thinking about where the mobius strip is.

We will never be able to conceptualize God until we become one with Him...............
