“The Galaxy at the End of the Universe” (Weekend Feature)

NGC 3432 Galaxy

 

Physicists have found that for the last 7 billion years or so — the anticipated halfway point of the lifetime of the cosmos – galactic expansion has been accelerating. Some unknown force is pushing the galaxies, adding energy to them. A force physicist have named “dark energy”.

Big Bang

 

“The Big Bang theory says nothing about what banged, why it banged, or what happened before it banged,” observed MIT theoretical physicist and cosmologist Alan Guth, who pioneered the the theory that the universe dramatically expanded in size in a fleeting fraction of a second after the Big Bang.

“Powering the Universe?” –Relic Light of the Big Bang Reveals an Exotic Unknown Force 

 

Dark Energy

 

Cosmologists speculate based on hints of twisted light that offer clues to an exotic substance called “quintessence”that could be the  unknown force accelerating the expansion of the universe, with implications not only for cosmology, but also for fundamental physics — the standard model of particle physics does not predict its existence.  This hypothetical form of dark energy –a relative of the Higgs Field that permeates the cosmos– could be an exotic unknown form of dark energy distinct  from any form of or normal matter, radiation, or even dark matter.

“Pulling & Twisting” –Ongoing Contortions from Milky Way’s Ancient Collision with Neighboring Dark Matter Halo

 

"Pulling & Twisting " --Ongoing Contortions from Milky Way's Ancient Collision with Neighboring Dark Matter Halo

 

The long-held belief that the Milky Way, harboring Earth and our solar system, is relatively static has been dispelled. In a violent, dynamic dance between two galaxies, the dark-matter halo of Large Magellanic Cloud (LMC) –a satellite galaxy one-hundredth as massive as the Milky Way, visible as a faint cloud in the southern hemisphere’s night skies – as observed by its namesake, the 16th century Portuguese explorer Ferdinand Magellan–is pulling and twisting the Milky Way spiral-shaped disc of stars and planets at 115,200 kilometers per hour towards the constellation Pegasus.
