New research adds knowledge on the creation and evolution of the universe

Posted by in categories: computing, cosmology, physics

The Computational Cosmology group of the Department of Astronomy and Astrophysics (DAA) of Valencia University (UV) has published an article in The Astrophysical Journal Letters, one of the international journals with the greatest impact in Astrophysics, which shows, with complex theoretical-computational models, that cosmic voids are constantly replenished with external matter.

“This totally unexpected result can have transcendental implications, not only for our understanding of the large-scale structure of the , but on the settings for the creation and evolution of galaxies,” explains Vicente Quilis, director at the DAA and head researcher for the project.

“Cosmic voids are the largest structures in the cosmos, and knowledge on their creation and evolution is essential to understand the of the universe,” says Susana Planelles, co-director of the research. Studying them as a physical occurrence has always been extremely complex precisely due to being large volumes with very low material content. From an observational point of view, analyzing the few existing items inside them is very hard, and the theoretical modeling of these occurrences is no less complex, which is why highly simplified descriptions of these structures are used.

Hydrogel Tablet Can Purify a Liter of River Water in an Hour

Posted by in categories: engineering, sustainability

AUSTIN, Texas — As much as a third of the world’s population does not have access to clean drinking water, according to some estimates, and half of the population could live in water-stressed areas by 2025. Finding a solution to this problem could save and improve lives for millions of people, and it is a high priority among scientists and engineers around the globe.

Scientists and engineers at The University of Texas at Austin have created a hydrogel tablet that can rapidly purify contaminated water. One tablet can disinfect a liter of river water and make it suitable for drinking in an hour or less.

“Our multifunctional hydrogel can make a big difference in mitigating global water scarcity because it is easy to use, highly efficient and potentially scalable up to mass production,” said Guihua Yu, an associate professor in the Cockrell School of Engineering’s Walker Department of Mechanical Engineering and Texas Materials Institute.

Watch A YouTuber Shut Off A Helicopter Engine Mid-Air — Just To Prove Neil deGrasse Tyson Wrong

Posted by in category: transportation

How do you settle an argument with someone who’s clearly in the wrong? Well, you show them a live demonstration, even if it means putting your life on the line but in the end, you have to show them who’s the boss am I right?

That’s exactly what Destin Sandlin from SmarterEveryDay YouTube channel did by shutting off the helicopter midair to prove a point. A few years ago, Neil deGrasse Tyson had made a statement that “An airplane whose engine fails is a glider. A helicopter whose engine fails is a brick.” which did not sit well with the Youtuber and he decided to prove Tyson and everyone once and for all, that that statement was in fact wrong and the reality was different. The video was shot in 2016 but it has been making the rounds once again.
