#Quasars are massive and extremely remote celestial object, emitting exceptionally large amounts of energy, and typically having a starlike image in a telescope. It has been suggested that quasars contain massive black holes and may represent a stage in the evolution of some #galaxies.

“We want to know what kind of galaxies these quasars live in. That can help us answer questions like: How can black holes grow so big so fast? Is there a relationship between the mass of the galaxy and the mass of the black hole, like we see in the nearby universe?” said lead author Madeline Marshall of the University of Melbourne in Australia, who conducted her work within the ARC Centre of Excellence in All Sky Astrophysics in 3 Dimensions.

Have you heard about astropolitics before? Mara Cortona is the Executive Director of the Astropolitics Institute: The world is going to end. Eventually. For most of us that concern is far away. The likelihood that we, humanity as a species, will survive the next century at 1 in 3. Why is no one focusing on the big problems? Poorly aligned Artificial General Intelligence, Biotechnology and other risks are significantly more dangerous than global warming or the 2020 election. https://youtu.be/ImcFOF5EX9A

In three more years we are 8 billions people on this planet.
