Fbod A Dusty Burp Could Explain Mysterious Dimming of Supergiant Star Betelgeuse
Astronomers love studying the life cycles of stars, including which stars die in which ways. Less-massive stars, like our Sun, expand and shed their layers as they transition into white dwarfs, while much bigger stars explode in violent supernovae, and their cores turn into black holes or neutron stars. But questions surround the ending of intermediate-size stars that have between seven and 11 times the mass of the Sun. Do they shed their layers or explode And if they do go supernova, whats the end product Understanding these stars in part relies on understanding the behavior of t

stanley cup becher , simulations have shown that they could form cores made of the elements oxygen, neon, and magnesium. These stars might either lose some of their outer hydrogen envelope and become dim white dwarf stars, or, if the core becomes large enough, collapse into a neutron star. But these cores are weird objects, where the pressure from the crushing gravity is offset by the quantum mechanical rules that govern electrons. Two electrons cannot share the exact same quantum properties, limiting how closely you can squish them together and exerting a degeneracy pressure on the core.

Following the media briefing, which focused on new exhibits and educational resources available at the Gilder Center, I and a few other members of the press鈥攊ncluding Ken Gale from New Yorks WBAI and Anthony Liversidge from the blog Science Guardian鈥攈ad a chance to catch up with Neil. Our conversation quickly grew heated as Liversidge, a reporter and science skeptic, expressed concerns about the safety of the Large Hadro

Gizmodo felt this recorded interview was the most important part of the day. We decided to publish it due to its relevance to todays political climate of open hostility toward scientific truth,聽as well as Neils explanation of some of the most unbelievable discoveries in modern physics. It has been condensed, edited and annotated for clarity. Gale did not return our multiple requests for comment, but we will update the piece if we hear back.
