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.

What is outside the universe?
I think a laboratory. We are a drop on a microscope slide.

If the Universe is ALL THERE IS, and it’s ‘Expanding’, what is it ‘Expanding’ into?......................

our universe may actually be a closed loop instead of a vast, never-ending expanse.

if our space has non-trivial topology, then light rays will "wrap around" our universe multiple times and you'll be able to see the same (similar) copies of galaxies.

Climate change is a 5 sigma confidence interval - otherwise called settled science.

The universe could be a giant loo.

Maybe it’s more like an hour glass and we are on the matter side of the black hole with our universe filling up.

On the other side of the hourglass is the anti matter side that is also expanding to counter balance us.

It’s all a continuous flow of energy. Ever expanding, ever contracting...

I just read a Sci-Fi novel where Earth and another civilization in another universe were shifting matter between the two universes in order to have ‘unlimited’ ‘free’ energy........to a point.................

Everything and everyone is consciousness of varying frequencies.

Science is slowly figuring this out.

Kepler thought that the universe had spheres which made music as they moved—the “music of the spheres.” If he was alive today and was told that the universe was a closed loop, he’d be looking for “loopy tunes.”

The problem is that the people on earth belong to the “Flat Consciousness Society.”

When they finally figure this out, they will find that the physical body is merely a cocoon for the transformation of consciousness.

When Descarte said “Cogito, ergo sum... i.e. I think therefore I am” he forgot to identify the “I” that was doing the thinking.

When individual consciousness grows, it increases in frequency and expands beyond the physical body.

When it sheds the low frequency physical body it reaches frequencies that exceeds the speed of light and time collapses.

Time is not a function of the speed of light. It is a function of the frequency of consciousness divided by the speed of light.

Einstein missed this in his theory of relativity thus he used C squared creating an error in his equation unless you only apply it in a “ Flat Consciousness Society. “

All these cosmologists telling us what they think about the universe.

They should stick to selling makeup.

A loop that folds over on itself means a planet a hundred light years away could be a ‘5 hour drive away’...
