Astronomers have reached a fundamental impasse in their understanding of the universe: they cannot agree how fast it is flying apart. And unless a reasonable explanation can be found for their differing estimates, they may be forced to completely rethink their ideas about time and space. Only new physics can now account for the cosmic conundrum they have uncovered, many believe.
You are made from star-dust! — a #cosmology for regenerative cultures

The ‘design’ brief to redesign the human impact on Earth from predominantly exploitative and destructive to by and large regenerative and health-generating invites us to ask fundamental questions that define the story we tell about the world and our role in it.Innovating and designing a regenerative #culture requires us to live the questions and reflect on our participatory relationship with life and nature. We need to re-examine the founding mythology (and scientific record) of our origin, the cosmological framework that defines our context and offers answers to: Where do we come from?; Who are we?; Where are we going?So, where do we come from? There are many ways to answer this question. Cosmology is how a culture answers this story. Over the last 250 years our scientific cosmology has (...)

Source: vox.comThe so called progressive industrialisation has probably done more harm to our planet than good. Today, the world has found itself amidst the crisis of waste management, specifically plastic waste management.If we step back and look at the bigger picture by the numbers, the picture is much more ugly than we can even imagine.Source: sailorsforthesea.orgThey said diamond is forever, but hey! Plastic is forever too.We all know how severe the problem of waste management is, especially for the developing countries due to lack of resources. This is where technology kicks in.According to a recent study, 90 percent of plastic debris in the ocean comes from 10 rivers, eight in Asia and two in Africa.Let’s talk about solutions.There is enough plastic in this entire world that we could (...)

A friend who pays attention to physics said that the lake should be frozen in the case where the sun is the Barnard’s star (a red dwarf) and completely disappeared (boiled to death) where the sun is the bright and giant Arcturus.
