Could Advanced Aliens Have Fine-Tuned Earth for Life?

That’s a surprisingly popular thesis, considering how hard it is to account for life without assuming a creator

Walter Bradley Center director Robert J. Marks has been doing a series of podcasts with Swedish mathematician Ola Hössjer, and Colombian biostatistician Daniel Díaz in connection with a recent co-authored paper on the fine-tuning of the universe for life in the Journal of Cosmology and Astroparticle Physics. In the first portion of this episode, podcast 153, “Why is there fine-tuning everywhere?” they looked at whether fine tuning of the universe for life can be accounted for by the theory that advanced life forms seeded life throughout the universe (directed panspermia). Surprisingly, perhaps, the theory is considered at least plausible, due to the difficulty of accounting for the existence of life otherwise. As Marks and his guests noted, great scientists such…

Theoretical Physicist Argues, the Sim Universe Is Pseudoscience

It’s a lot of fun in science fiction and some scitech celebs buy in. But Sabine Hossenfelder and others explain why it’s fiction

Theoretical physicist Sabine Hossenfelder does not like the notion that we are living in a giant computer sim. Elon Musk likes it (“Elon Musk says there’s a ‘one in billions’ chance reality is not a simulation”) and so does Neil deGrasse Tyson (“Neil deGrasse Tyson says it’s ‘very likely’ the universe is a simulation”). Philosopher of science Nick Bostrom advanced that view in a seminal 2003 paper in Philosophical Quarterly. Former Astronomer Royal Martin Rees is sympathetic to it. Some call it the Planetarium hypothesis, when it is cited as a reason we do not see intelligent extraterrestrials. One source offers “15 irrefutable reasons” why, like Neo in The Matrix (1999), we might be living in a universe that is…

How Can We Be Sure We Are Not Just An ET’s Simulation?

A number of books and films are based on the Planetarium Hypothesis. Should we believe it?

Science and science fiction writer Matt Williams has been writing a series at Universe Today on why the extraterrestrial intelligences that many believe must exist in our universe never show up. Last week, we looked at the Prime Directive hypothesis (The Directive is, don’t interfere in the evolution of alien societies, even if you have good intentions.”) This week, let’s look at the Planetarium hypothesis, the sixth in his series: “humanity is in a simulation, and the aliens are the ones running it! In order to ensure that human beings do not become aware of this fact, they ensure that the simulation presents us with a “Great Silence” whenever we look out and listen to the depths of space.” (August…
