Highly energetic particles from outer space travelling at the speed of light, known as cosmic rays, originate from the sites of extreme particle acceleration in the Universe.
There is a seismic shift underway in economics, hastened by the aftermath of the Covid-19 pandemic. Communities and countries around the world are beginning to adopt/consider adopting well-being and prosperity as major guiding principles.
