Neutrino Mysteries
The source of a high-energy neutrino detected at the South Pole has been traced for the first time--to a distant galaxy 4 billion light years away. Astrophysicist Azadeh Keivani tells us how this was done, with the help of multiple observatories. Meanwhile, physicists working at the Miniboone experiment may have spotted signs of new physics--possibly a new type of 'sterile' neutrino. Physicist Richard Van de Water explains more.

Fuzzballs Solve Black Hole Paradox
String theorist Samir Mathur has developed a model in which black holes are replaced by fuzzy balls of string, with no singularities and no event horizon. He explains to Sophie Hebden how fuzzballs solve the black hole information paradox and may rewrite the Big Bang.

Almost Quantum
Physicist Miguel Navascues is on a mission to overturn quantum theory and replace it with a deeper framework, with almost--but not quite--the same set of weird properties of quantum theory, as he explains to reporter Colin Stuart.

Testing Free Will with AI
Could developments in machine learning give scientists a way to test if free will is real, an emergent phenomenon, or an illusion? Physicist Avi Loeb explains to reporter John Farrell how he thinks they could--and why this is important for our sense of moral responsibility.

A system, e.g. the universe-system, is not just a set of distinct rules [1].

It is necessary that something somehow knows about/ can distinguish these distinct rules; and it is necessary that something somehow creates these distinct rules [1]. The knowledge/ creativity aspects are necessary aspects underlying any system.

Any system cannot be understood unless the knowledge and creativity aspects are recognized/ conceded/ admitted to.

When it comes to our universe, the...


“Intelligence” is “military or political information” and “the collection of information of military or political value”[1]. I.e. in more general terms, “intelligence” is knowledge that we have the ability to gather of a situation that we find ourselves in.

What a lot of people (including Loeb) seemingly find very hard to grasp is the fact that machines can only operate because they process symbolic representations of this information/ knowledge/ military...


“Machine learning” is just words that some rather silly people take far too seriously. Only silly people believe that machines have “intelligence”, or that machines “learn from experience and educate themselves”, or that machines have “will”. Physicist Avi Loeb spouts an awful lot of nonsense.

So how do we actually “shape reality”? The necessary logic of such a system is clear:

1. If all outcomes in a system have been 100% determined by a fixed set of rules...
