At least, a better way to simulate the accretion of Supermassive Black Hole at the Center of the Milky Way. A Better Way to Simulate Accretion of the Supermassive Black Hole at the Center of the Milky Way Scientists at Princeton University and the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed…

And it’s from outside the Milky Way too. Astronomers Have Traced The Source of The Most Powerful Radio Signal Ever Received From Space Scientists have observed the most powerful fast radio burst (FRB) ever – an intensely brilliant burst of radiation emanating from outside our own Milky Way galaxy.

Some cool news from “my” Uni – Swinburne.  Cosmic ‘barcode’ from distant galaxy confirms Nature’s constancy Cosmic ‘barcode’ from distant galaxy confirms Nature’s constancy Astronomers have confirmed that electromagnetism in a distant galaxy has the same strength as here on Earth Source: www.swinburne.edu.au/news/latest-news/2016/11/cosmic-barcode-from-distant-galaxy-confirms-natures-constancy.php

If we’re in a simulated Universe, can we “break out” of it?  Breaking into the Simulated Universe I argued in my 2015 paper “Why it matters that you realize you’re in a Computer Simulation” that if our universe is indeed a computer simulation, then that particular discovery should be commonplace among the intelligent lifeforms throughout…

Are Fast Radio Bursts (FRB) an answer to Dark Matter? https://m.phys.org/news/2016-08-cosmic-enigma-astrophysicists-fast-radio.html 400 Bad request ​A massive cluster of yellowish galaxies, seemingly caught in a red and blue spider web of eerily distorted background galaxies, makes for a spellbinding picture from the new Advanced Camera for Surveys aboard NASA’s Hubble Space Telescope. To make this unprecedented…

No, dark matter is not messing up GPS measurements While you sit and read this blog post, dark matter particles are passing through your body, without you ever noticing. Whether you find that creepy or not depends on your mindset, of course; to dar… Source: galileospendulum.org/2014/01/02/no-dark-matter-is-not-messing-up-gps-measurements/
