This is one of those pieces of news that seems to be a joy to the terraplanistas, but the truth is that there is nothing further away. A group of scientists from the University of Portsmouth in England demonstrated how large structures in the distribution of galaxies in the Universe provide the most accurate evidence of dark energy and cosmic expansion to date.
To do the research, A new method was used based on a combination of cosmic voids (large expanding space bubbles containing very few galaxies) and the slight imprint of sound waves in the early universe, known as baryonic acoustic oscillations (BAOs), which can be seen in the distribution of galaxies.
The results confirm the model of a constant cosmological dark energy and a spatially flat universe with a precision unprecedented, and strongly disapprove recent suggestions for positive spatial curvature inferred from satellite cosmic microwave background (CMB) measurements Planck.
Dr. Seshadri Nadathur, a researcher at the University’s Institute of Cosmology and Gravitation (ICG), commented that, “eThis result shows the power of galaxy studies to determine the amount of dark energy and how it evolved in the last billion years. We are doing really accurate measurements now and the data will get even better with new surveys coming online very soon. ”
Now based on a Quantamagazine article, it is important not to understand this “flatness” of the universe as an extended sheet of paper, rather, “eThe simplest example of a flat three-dimensional shape is ordinary infinite space, what mathematicians call Euclidean space. “
An example is what they call the donut shape, where joining the flat shapes would obtain a shape like that of a cylindrical thread.
Also called a Torus shape: a three-dimensional surface that results from rotating a circle about an axis that does not cut it.
“These paths look curved on a distorted bull, but for flat bull dwellers they feel straight. And since light travels along straight paths, if you look forward in one of these directions, you will see it from behind, ”as shown in the image below.
