The universe could be shaped like a giant donut according to a study from Cornell University

Scientists and researchers at

in New York came to the conclusion, after a series of calculations, that the universe could be the size of a giant doughnut. 

The strange patterns found in the echoes of the Big Bang could be explained by a universe with a more complicated shape

, and astronomers have not fully verified the flatness of the universe, according to the study.

Observations made so far suggest that the universe is flat.

In geometry, "flatness" refers to the behavior of parallel lines when extended to infinity.  

The donut would be the equivalence of the Universe according to mathematicians.

Instead, let's look at Earth.

Lines of longitude start out perfectly parallel at the equator, but eventually converge at the poles.

The fact that the parallel lines initially intersect reveals that the Earth is not flat.

Astronomers have calculated the predicted size of those fluctuations compared to observations.

If the measured size differs from the predictions, it means that certain rays of light, which started out as parallel

Mathematicians have discovered 18 possible geometrically flat three-dimensional topologies.

In each of them, at least one dimension wraps around itself and sometimes flips like a Möbius strip or performs partial rotations.

If the universe were a giant donut, astronomers could look in two directions to see its reproductions. 

The universe would have a strange shape.

Astronomers have measured the topology of the universe in multiple ways, from finding duplicates to galaxy patterns.

All evidence suggests that the universe is geometrically flat and has a simple unenvelope topology.

But the Cornell University paper, published on February 23, suggests that previous measurements have been limited.

In particular, observations have assumed that the universe wraps around itself in a single dimension and does not have a more complicated topology.

In fact, a universe with a complicated topology could explain at least some of the anomalies.

Although this is not an irrefutable case of complicated topologies, the researchers offer ideas for more sophisticated forward searches.
