According to an analysis by astronomers at Yale and the European Southern Observatory, the maximum size a black hole may reach is only few tens of billion of solar masses. The limit was calculated using an analysis of what may happen to the gas surrounding a black hole which has reached few tens of billions of solar masses. It is thought that black holes of such size heat the surrounding gas to a temperature where the radiation pressure begins blowing outer layers into space."

ElementC writes "Team Twiizers, the group behind almost all of the Wii Homebrew scene, has released an update to the Homebrew Channel (and installer) that allows for installation on a Wii with the most recent update installed. While the team still recommends against installing the Nintendo update, those who accidentally updated or purchase games that require the update are no longer left out to dry. This update to the Homebrew Channel also adds SDHC support, a feature Nintendo has not implemented in vanilla Wiis. The community has also created an app that updates just the Wii Shop Channel — allowing users to purchase Wiiware and Virtual Console games without losing their homebrew. It took the team only two days to get the fix out."

Kotaku recently ran a story questioning whether the survival-horror genre still exists, and how Dead Space may or may not fit into it. With reviews for the game starting to come in, Ars Technica reports that the game is, indeed, both scary and good. Gamespy wrote up a Dead Space survival guide, and Gamasutra has a lengthy interview with the game's senior producer. In the production of the game, the developers studied things like car wrecks and war scenes to increase the level of realism. They also want the game's sounds to terrify players, including appropriately timed silence. The launch trailer is also available, though it does contain spoilers.
