Is the universe infinite? What does science really know about the shape of the universe?

  • 5 תגובות
Measurements of the cosmic microwave background radiation indicate that the observable universe is approximately flat, but scientists still do not know whether the entire universe is infinite, finite without an edge, or has a more complex topological structure.

Scientific breakthrough: A cyclic electromagnetic structure based on topological bonds has been measured for the first time

  • One response
Researchers from Tel Aviv University and Rafael have developed an innovative metasurface based on conductive loops in the form of bonds, which allows precise control of electromagnetic waves – and has been measured for the first time in an experiment.
A tesseract (a four-dimensional cube) and the "shadow" it casts on a plane - the quasi-crystal discovered by Shechtman. According to Prof. Bartel, "The fact that a quasi-crystal is a "shadow" of a high-dimensional periodic crystal is not new in itself. We discovered that the casting is not only of but also of topological properties such as holes, distortions or vortices." Illustration: Florian Sterl, Sterltech Optics

Greetings from the Fourth Dimension: Technion Researchers Unveil New Breakthrough in the Field of Quasi-Crystals
