The universe hasn’t existed forever and a lot of stuff has happened in its history, so the oldest light we can see doesn’t come from close to the cosmic event horizon. Even so, the same slowing/reddening effect is visible to the naked eye. A lot of galaxies in a very small corne...
Rejoices Profound and StillAs we stared beyond the windows thereOver all the gardensThat have never beenAnd will never grow againHow longHow longThe shining winking starsThe clouds too highSo highPointing to some final starThe dull face of the skyAnd the sound of the callingOf the distant vi...
Similarly, cosmologists working to decipher the origin and fate of the universe must identify with The Boss' sense of tragic yearning. These stargazing scientists have been facing their own darkness on the edge of town (or on the edge of galaxies) for a long time as they try to explain ...
To determine how distant a galaxy is, how long its light has been traveling to us and thus what period the universe was in during the time we have witnessed it it, astronomers use a measure called "redshift." Different wavelengths of light correspond to different colors; so in the visibl...
It seems entirely possible to me that every globular cluster that has ever existed anywhere in the known universe is still extant. Unless the cluster is disrupted by an external source and dispersed (highly unlikely) each individual star will die its own death (lots of planetary nebulae to be...

Within each universe, while lying on a bed of celestial snakes floating on the universal waters. Garbhodaksayi Visnu creates Brahma, whom He empowers to create all planets and all species of life. Brahma, who in this universe has four heads, is born from a lotus sprouting from the navel...
The International Space Station (ISS) provides a cooperative platform on which to research the critical challenges of putting humans in space for a sustained period of time. And researchers must overcome these challenges before any long flights and permanent habitats in space can happen. Astronaut Im...
Still, we've come a long way in our understanding. Some of the brightest minds in the history of science have focused their powerful intellects on the subject. Albert Einstein tried to imagine what it would be like to ride on a beam of light. "What if one were to run after a ray ...
The notion of the metaverse has existed for decades [4]. However, only after thirty years does the term “metaverse” begin to have more defined contours. In fact, in 2021 Mark Zuckerberg, with the transition from Facebook to Meta, brought the term and the concept of “metaverse” back ...
