چکیده موضوع پژوهش حاضر بررسی نقادانۀ چالش استاندارد دربارۀ صورتبندی نوینی از برهان نظم است؛ چالشی معرفتشناسانه که با تلقّی فلسفی خاصی از اصل آنتروپیک (/ اصل)، به برهان تنظیمِ ظریفِ کیهانی (/ برهان) وارد شده است. بر مبنای این چالش، ابراز شگفتی ما از مشاهدۀ جهانی پذیرای حیات، که احتمال پیشینی آن بیاندازه ناچیز است، بیمورد است، چراکه انسان نمیتواند خود را در جهانی که با شرایط حضورش وفق ندارد، ب...
The human body is a constant flux of thousands of chemical/biological interactions and processes connecting molecules, cells, organs, and fluids, throughout the brain, body, and nervous system. Up until recently it was thought that all these interactions operated in a linear sequence, passing on information much like a runner passing the baton to the next runner. However, the latest findings in...
مسئله تنظیم ظریف در کیهان شناسی معاصر، مسئله ای است که به نظر می رسد نیازمند تبیین است. تبیینی که برخی فیزیکدانان سرشناس برای آن ارائه داده اند، استفاده از استدلال آنتروپیک مبتنی بر چندجهانی است. در این مقاله پس از معرفی مفهوم چندجهانی، تنظیم ظریف و انواع آن و همچنین اصل و استدلال آنتروپیک، استدلال خواهد شد که به نظر نمی رسد تبیین این فیزیکدانان، هدف آنان را که ارائه توضیحی معقول برای تنظیم ظری...
A general cosmological principle — Aleph — is proposed as a substitute to the Anthropic principle. Furthermore, the universe, conceived as a world ensemble, is characterized by many (possibly infinite) X-Life world principles. The only known X-Life world principle recovers much of the Anthropic conjecture. The inescapable final conclusion is the formulation of the Strong Copernicus principle.
The usage of the anthropic principle in modern cosmology is reviewed. It is argued that its recent use to explain the observed values of cosmological parameters as most probable values for an ensemble of universes, is not justified. However, the anthropic principle can be invoked to argue that a vast number of universes must exist, in which the cosmological parameters and constants of nature ta...
A brief explanation of the meaning of the anthropic principle – as a prescription for the attribution of a priori probability weighting – is illustrated by various cosmological and local applications, in which the relevant conclusions are contrasted with those that could be obtained from (less plausible) alternative prescriptions such as the vaguer and less restrictive ubiquity principle, or th...
In the Middle Age, official science said wrongly we are in a very special location, but now it says we are living a special epoch. Indeed, in the famous article of Carr and Rees, 'The anthropic principle and the structure of the physical world', published by Nature (278, 605-612 (1979)) one reads “All these scales can be deduced directly from known physics except the mass and length scale of th...
We propose an alternative anthropic probability for calculating the probabilities in eternal inflation. This anthropic probability follows naturally from the weak anthropic principle, and does not suffer the freak observer or the typicality problems. The problem that our observed cosmological constant is not at the peak of the usual anthropic probability distribution is also solved using this p...
