“First Second After” –Gravitational Waves Unveil Secrets of the Big Bang

Gravitational Waves-LIGO

 

“It is undeniable that we are profoundly puzzled, especially when it comes to the first fraction of a second that followed the Big Bang,” wrote theoretical physicist Dan Hooper, author of The Edge of Time in an email to The Daily Galaxy–Great Discoveries Channel. “I have no doubt that these earliest moments hold incredible secrets, but our universe holds its secrets closely. It is up to us to coax those secrets from its grip, transforming them from mystery into discovery.”

Wormholes Could Be Hiding Within Dark Matter

Wormhole

 

“If we combine the map of the dark matter in the Milky Way with the most recent Big Bang model to explain the universe and we hypothesize the existence of space-time tunnels, what we get is that our galaxy could really contain one of these tunnels, and that the tunnel could even be the size of the galaxy itself. But there’s more,” explained Paolo Salucci, astrophysicist with SISSA and a dark matter expert. “We could even travel through this tunnel, since, based on our calculations, it could be navigable.”  Salucci is among the authors of the paper published in Annals of Physics.

Beyond the Edge of the Milky Way: Giant Pulsating Stars Revealed an Enormous Halo of Dark Matter

Galaxy NGC 474

 

One early result of the 2nd release of the still ongoing Dark Energy Survey is the previously untold story revealed by old, giant RR Lyrae (RRL) pulsating stars with a mass of around half the sun’s, which tell scientists about the region of space beyond the edge of our Milky Way. These large-amplitude stars serve as tracers and distance indicators of old stellar populations in the Milky Way and neighboring galaxies. They are also essential laboratories for testing evolutionary and pulsation models.
