Did you know?

"An Elliptic Curve Primality Proving (ECPP) algorithm was used via a primality proving program, Primo 4.3.0 - LX64, to generate a primality certificate which deterministically verifies the primality of p. The certification process took 39 days and 8 hours to complete using an AMD Ryzen Threadripper 2950X (16-Core, 32-Thread, 3.5GHz Base)."

> The astrophysicists, from the University of Cambridge, the University of Trento, and Harvard University, say that there is a clear, unambiguous signal in the cosmos that could eliminate inflation as a possibility.

> “Inflation was theorised to explain various fine-tuning challenges of the so-called hot Big Bang model,” ... “It also explains the origin of structure in our Universe as a result of quantum fluctuations.”

> However, the Big Bang theory does not allow for the existence of the CGB, as it suggests that the exponential inflation of the newborn universe diluted relics such as the CGB to a point that they are undetectable. This can be turned into a test: if the CGB [cosmic graviton background] were detected, clearly this would rule out cosmic inflation, which does not allow for its existence.

Nouriel Roubini says it’s ‘mission impossible’ to avoid a hard landing, and we’ll get the worst of the 1970s and 2000s combined

> Fed Chairman Jerome Powell still says it’s possible to cool the economy and keep employment stable—all without causing a severe downturn, in what would be a “soft landing.”

> But if history is any indication, a recession and an economic “hard landing” are all but guaranteed, says Nouriel Roubini, professor emeritus at New York University’s Stern School of Business and the CEO of Roubini Macro Associates. He earned the nickname “Dr. Doom” for his prophetic visions of looming economic downturns, including an accurate prediction of the 2008 housing crash and subsequent market crisis.

> With the U.S. annual inflation rate as high as it is—8.2% in October—only a deep recession and a steep spike in unemployment might be enough to fix it, Roubini warned in a recent interview with Fortune.
