Event Horizon - a modern myth?

GR is valid on large scales and is, therefore, a simplification of the unknown GUT. As such, the mathematical solutions obtained in GR are strictly speaking valid only within GR. Certainly, the solution called black hole is an extremely heavy object and at the same time extremely small - a point without geometrical extension. The latter is heavily in conflict with the validity range of the underlying theory and, hence, makes lots of people (including experts unlike me) question the concept of black holes despite the fact that something has been "observed" which fits into this concept. Regarding the movie: Event Horizon might be a myth but it emphasizes what Sante said in on of his presentations: Don't use a black hole for travelling, take the worm hole instead. The constructor of Event Horizon created a black hole not considering that the damn thing has no exit...where did he think the Event Horizon would end?

nice list and discussion sent originally by Andrés ....

Everything you wanted to know about se... um... ecology. Very interesting, myth-busting article.

A good idea for a card in one of our ACT magic decks!!! In his words AI is "our biggest existential threat" - lol

the "even" in your comment is the key word

Edge.org recently had an interesting piece that ties into all of this recent AI fear mongering: http://edge.org/conversation/the-myth-of-ai
