Cosmologist George Ellis on the philosophical problems of cosmology — and a note from Rob Sheldon

Ellis: Humans have demonstrably contemplated purpose and meaning and ethics for millennia and their existence is data on how things are. The existence of these possibility spaces is part of the deep structure of the cosmos, in the way that I have proposed above. In that sense, meaning is built into the foundations of existence.

At Mind Matters News: The UFOs Carl Sagan was convinced of but couldn’t talk about

Sagan was denied tenure at Harvard for being, according to Zabel, a little too “out there.” But today, Harvard astronomer Avi Loeb openly discusses his thoughts on ETs and UFOs in popular science venues. And, in what sounds like a helpful move, NASA is seeking standards for ET life claims, rather than just denying or avoiding them altogether. Read More ›

Sabine Hossenfelder asks, what’s up with neutrinos?

Hossenfelder has stumbled on a telling fact about science journalism. Often, the genuinely puzzling problem is ignored in favour of some a big whoop de do about an incidental find that doesn’t amount to much and may prove an artifact of data collection. Read More ›

Rob Sheldon: “It from bit” is winning the cosmology wars

Sheldon: Translating, Ethan is saying that the old 20th century materialism that says "entropy" or "information" emerges from the particles is being replaced by a 21st century view that "entropy" or "information" is fundamental and the material particles emerge from the immaterial field.

At Mind Matters News: Researchers: The universe simulated itself into existence

The paper, which appeared in Entropy in 2020, is open access. The most significant element of this new theory is surely that it is explicitly a theory of “panconsciousness” and non-materialism. Read More ›

Sabine Hossenfelder: New evidence against the Standard Model of cosmology

Hossenfelder: "... the evidence is mounting that the cosmological principle is a bad assumption to develop a model for the entire universe and it probably has to go. It increasingly looks like we live in a region in the universe that happens to have a significantly lower density than the average in the visible universe." Read More ›

Dark matter as Fermi balls? Rob Sheldon offers a question

Sheldon: Quite surprisingly, such a theory is readily available for testing. Remember, dark matter avoids the center of galaxies, but neither does it condense into stellar-sized black holes (we looked). So if it is little balls created in the Big Bang, then it is indistinguishable from Primordial Black Holes that have been proposed for decades... Read More ›

At Mind Matters News: Quantum physicist shows how consciousness may create reality

In his argument against physicalism (physical nature is all there is), Tim Andersen draws from the 19th-century philosopher Schopenhauer the concept of Will as the basis of all reality. Read More ›

Sabine Hossenfelder despairs over vacuum energy. Rob Sheldon responds

These specialty controversies are an interesting backdrop to the current war on math. Sabine Hossenfelder and Rob Sheldon would likely agree that 2 + 2 = 4. But survey the vast degreed hordes for whom such a statement is an instance of white supremacy and colonialism and we will see the real problem facing our civilization: Far too many people have degrees (and grievances!) but no insight into what knowledge is.

Rob Sheldon offers some comments on Karsten Pultz’s “Bicycle” ID thesis

Sheldon: "... in computer science, it is very difficult to make a random number generator. Successive runs of the code should not produce the same numbers. But most generators do." Read More ›
