L&FP, 70: Exploring cosmological fine tuning using the idea of a 3-D, universal printer and constructor (also, islands of function)

Last time, we looked at how Kolmogorov Complexity can be used to quantify the information in functionally specific complex organisation, by using the formal idea of a 3-D universal printer and constructor, 3-DP/C: . . . it is but a short step to imagine a universal constructor device which, fed a compact description in a suitable language, will construct and present the [obviously, finite] object. Let us call this the universal 3-D printer/constructor, 3-DP/C. Thus, in principle, reduction of an organised entity to a description in a suitably compact language is formally equivalent in information terms to the object, once 3-DP/C is present as a conceptual entity. So, WLOG, reduction to compact description in a compact language d(E) is readily Read More ›

At Phys.org: Planetary interiors in TRAPPIST-1 system could be affected by solar flares

It's worth realizing that if the energy from stellar flaring is sufficient to noticeably heat the entire planet, it's more than enough to "cook its goose." Read More ›

At PopSci.com: With one snapshot, Apollo 17 transformed our vision of Earth forever

Today, we can realize how geographically limited our planet really is--it's the only place in the solar system that could support our civilization. We can be thankful for how well our needs are met by Earth's physical design and resources. Read More ›

At Science Daily: Seeing universe’s most massive known star

By harnessing the capabilities of the Gemini South telescope in Chile, astronomers have obtained the sharpest image ever of the star R136a1, the most massive known star in the universe. Their research challenges our understanding of the most massive stars and suggests that they may not be as massive as previously thought. Astronomers have yet to fully understand how the most massive stars — those more than 100 times the mass of the Sun — are formed. One particularly challenging piece of this puzzle is obtaining observations of these giants, which typically dwell in the densely populated hearts of dust-shrouded star clusters. Giant stars also live fast and die young, burning through their fuel reserves in only a few million Read More ›
