¿Existen Fisuras en el Universo?

Summary

The video explores the intriguing possibility that the universe contains fissures or topological defects, known as cosmic strings, formed during phase transitions in the early cosmos. It explains how symmetry breaking, similar to the formation of cracks in ice as it freezes, could have created massive energy structures. Although initially considered responsible for the formation of galactic structures, they were ruled out by inflation theory. However, their theoretical connection to superstrings and the recent detection of gravitational waves have renewed scientific interest in searching for them using advanced telescopes.

Transcript excerpt

Puede que el universo esté roto, que presente fisuras formadas en sus primeros instantes, cicatrices del cosmos primitivo. Algunas atravesarían el universo observable de punta a punta. Otras podrían formar bucles cerrados más pequeños. Todavía no hemos visto ninguna. Pero, ¿qué son exactamente? ¿Por qué pensamos que pueden existir? ¿Y cómo podríamos detectarlas? Vamos a verlo. We know that stars exist. We know that galaxies exist. STR astronomicals as black holes. So maybe out there are new astronomical objects that we have now to discover.

A planet exist because there is this force that pulls things together, gravity, and there is another force that push them apart. And the equilibrium between those things makes planets stable, ma…
