This is a scientifically accurate depiction of where a select few sci-fi star systems are in our galaxy. This has been an obsession of mine for the past few months to show this visually and get a feel for where these systems are around the solar system. Also, it should be noted, that the relative positions of the stars are accurate, but their size is not.

American physicist, John Wheeler (1911−2008), made seminal contributions to the theories of quantum gravity and nuclear fission, but is best known for coining the term ‘black holes’. A keen teacher and mentor, he was also a key figure in the Manhattan Project. [Listener: Ken Ford]
TRANSCRIPT: I knew the stories about Gödel being concerned always about his health. I knew from his friend Oscar Morgenstern how Gödel would never take a pills prescription from his doctor without getting out a big medical book and studying up on that pill himself to make sure that it was okay. But I didn’t realize how far his dreams went, because I had failed to resonate to a talk he gave in 1945 at the symposium held in honor of Einstein’s birthday. In that talk Gödel had described what he called a Rotating Universe, a universe where all the galaxies turn the same way, and where the geometry is such that you keep on going living your life and you come round and come back and can live it over again; ‘Closed Time-like Line’ was the magic phrase to describe it. So you didn’t have to worry about the pill because you come back and live your life all over again. Well, after I’d introduced the two I said “Professor Gödel, we’d like to know what the relation is between the great Heisenberg Principle of Uncertainty or Indeterminism; and your famous proof that every significant mathematical system contains theorems which cannot be proven, your theorem of Unprovable Propositions.” Well, he didn’t want to talk about that. It turned out that later that he had walked and talked enough with Einstein to dismiss quantum theory. He didn’t believe quantum[theory]. All he wanted to know is what we were going to say in our book about the rotating universe that he had described. Well actually, we weren’t saying anything. Well, this bothered him and he wanted to know what the evidence is today, at that moment, about whether galaxies do rotate in the same way. We said we hadn’t studied it. Well it turned out that he himself had taken out the great Hubble atlas of the galaxies and page after page had opened it up and looked at each galaxy, determined the direction of its axis. He made a statistics of these numbers and found there was no preferred direction of rotation, so they couldn’t all be rotating in the same way.
Have we already gone too far??

An international team of researchers has developed a new theoretical framework that bridges physics and biology to provide a unified approach for understanding how complexity and evolution emerge in nature.
This new work on “assembly theory,” published today in Nature, represents a major advance in our fundamental comprehension of biological evolution and how it is governed by the physical laws of the universe. The paper is titled “Assembly Theory Explains and Quantifies Selection and Evolution.”
This research builds on the team’s previous work developing assembly theory as an empirically validated approach to life detection, with implications for the search for alien life and efforts to evolve new life forms in the laboratory.

How do we know the age of the planets and stars? – Swara D., age 13, Thane, India
Measuring the ages of planets and stars helps scientists understand when they formed and how they change – and, in the case of planets, if life has had time to have evolved on them.

Ultimately, the researchers discovered 270 different cycles of autocatalytic reactions. “Autocatalysis may not be that rare, but instead it might be a general feature of many different environments, even those that are really different from Earth,” Kaçar said.

Most of the 270 cycles did not employ organic compounds. Some centered around elements that are absent or exceedingly rare in life on Earth, such as mercury, or the radioactive metal thorium. A number of cycles likely only happen under extremely high or low temperatures or pressures.
“Due to their ability to produce oxygen and function as bio-factories, this biotechnology could significantly enhance future space missions and human space exploration efforts,” Nicol Caplin, an astrobiologist at the European Space Agency (ESA), said in a statement.

Kombucha cultures, which are multi-species mélanges of bacteria and yeast, are key to creating the beverage. Add one such culture to room-temperature sweetened tea and, as long as the tea has plenty of sugar, microbes within will consume those nutrients, multiply and ferment the tea.
Self-sustaining chemical reactions that could support biology radically different from life as we know it might exist on many different planets using a variety of elements beyond the carbon upon which Earth’s life is based, a new study finds.
On Earth, life is based on organic compounds. These molecules are composed of carbon and often include other elements such as hydrogen, oxygen, nitrogen, phosphorus and sulfur.
