Globular star cluster Omega Centauri, also known as NGC 5139, is 15,000 light-years away. The cluster is packed with about 10 million stars much older than the Sun within a volume about 150 light-years in diameter. It's the largest and brightest of 200 or so known globular clusters that roam the halo of our Milky Way galaxy. Though most star clusters consist of stars with the same age and composition, the enigmatic Omega Cen exhibits the presence of different stellar populations with a spread of ages and chemical abundances. In fact, Omega Cen may be the remnant core of a small galaxy merging with the Milky Way. With a yellowish hue, Omega Centauri's red giant stars are easy to pick out in this sharp, color telescopic view.

Word for "universe" around Europe.
by danielogiPL
Notes:
All of the languages are color coded by the roots of the word, which I have done research on. All the yellow areas use the "omni/whole/all/entire" + "world" combination, hence they are grouped together but with slightly different shades. Please note this is only the case for the yellow areas; the blue areas all differ from each other. The Belarusian etymology is different from the yellow areas, as "cy" does not mean "whole". Also note that I was not able to find the etymologies for all of the translations (like Baltic, Breton/Cornish and Slovene; I tried really hard to find the one for Slovene). Please let me know whatever is wrong with the colors or translations, and I might re-upload the map with a few corrected mistakes.
There are a few languages where I couldn't find the translation, most notably Ossetian, Karelian and all the Sami languages. Please let me know any missing translations. Austria is colored the same as Germany; I keep having people commenting on Austria being empty, except it isn't, it speaks the same language as Germany does.

DARK MATTER DOESN'T EXIST IN OUR UNIVERSE??
Blog#387
Wednesday, March 27th, 2024.
Welcome back,
The composition of the universe, as we currently understand it, is thought to comprise 'normal matter,' 'dark energy,' and 'dark matter.' However, a recent study from the University of Ottawa sheds new light on this notion, suggesting that dark matter might not actually be a necessary component.
Tumblr media
Dark matter is a term used in cosmology to describe entities that don't interact with light or the electromagnetic field, and can only be inferred through gravitational effects. Essentially, it's invisible and its composition remains a mystery, yet it plays a crucial role in our comprehension of the behavior of galaxies, planets, and stars.
Tumblr media
Professor Rajendra Gupta, from the Faculty of Science at the University of Ottawa, conducted this groundbreaking study. He utilized a blend of the covarying coupling constants (CCC) and "tired light" (TL) theories, amalgamating them into what's termed the CCC+TL model.
This model proposes that the forces of nature diminish over cosmic time and that light loses energy during its extensive travels.
Tumblr media
Gupta's model has been rigorously tested against various observations, including the distribution of galaxies and the evolution of light from the early universe.
This study challenges the prevailing understanding of the universe, which posits that approximately 27% of its composition consists of dark matter, with less than 5% being ordinary matter, leaving the rest attributed to dark energy.
Tumblr media
Gupta said, "The findings from our study affirm our prior research on the age of the universe, which concluded it to be approximately 26.7 billion years old, and demonstrate that the universe may not necessitate the presence of dark matter."
He further explains that while standard cosmology attributes the accelerated expansion of the universe to dark energy, it is actually the weakening of natural forces as the universe expands that drives this phenomenon, not dark energy.
Tumblr media
The concept of "redshifts" plays a pivotal role in this study. Redshifts occur when light shifts towards the red end of the spectrum. Gupta scrutinized data from recent papers on galaxy distribution at low redshifts and the angular size of the sound horizon from literature at high redshifts.
