Today's post, Should We Ban Physics? was originally published on 21 July 2008. A summary (taken from the LW wiki):
There is a chance, however remote, that novel physics experiments could destroy the earth. Is banning physics experiments a good idea?
Discuss the post here (rather than in the comments to the original post).
This post is part of the Rerunning the Sequences series, where we'll be going through Eliezer Yudkowsky's old posts in order so that people who are interested can (re-)read and discuss them. The previous post was Existential Angst Factory, and you can use the sequence_reruns tag or rss feed to follow the rest of the series.
Sequence reruns are a community-driven effort. You can participate by re-reading the sequence post, discussing it here, posting the next day's sequence reruns post, or summarizing forthcoming articles on the wiki. Go here for more details, or to have meta discussions about the Rerunning the Sequences series.
As opposed to the train industry, who tried to have them outlawed as it was?
I am not sure what the purpose of the original post was. It asks questions that have no answers.
Certainly there are answers: You either ban physics experiments, or not. So in actual fact, as opposed to airy theory, we have chosen "No, we do not ban physics".
Which ones? The stuff with the Tegmark type 4 universe?
