    Does Life Really Need Planets? Maybe Not

    Do we have a planetary bias when it comes to understanding where life can perpetuate? It’s only natural that we do. After all, we’re on one.

    However, planets may not be necessary for life, and a pair of scientists from Scotland and the USA are inviting us to reconsider the notion.

    We focus on planets as habitats for life because they meet the conditions necessary for life to survive. Liquid water, the right temperature and pressure to keep it in a liquid state, and protection from harmful radiation are the primary requirements for photosynthetic life. But what if other environments, even ones maintained by organisms themselves, can also provide these necessities?

Finding Things At EpicureanFriends.com

What's the best strategy for finding things on EpicureanFriends.com? Here's a suggested search strategy:

  • First, familiarize yourself with the list of forums. The best way to find threads related to a particular topic is to look in the relevant forum. Over the years most people have tried to start threads according to forum topic, and we regularly move threads from our "general discussion" area over to forums with more descriptive titles.
  • Use the "Search" facility at the top right of every page. Note that the search box asks you what section of the forum you'd like to search. If you don't know, select "Everywhere." Also check the "Search Assistance" page.
  • Use the "Tag" facility, starting with the "Key Tags By Topic" in the right hand navigation pane, or using the "Search By Tag" page, or the "Tag Overview" page which contains a list of all tags alphabetically. We curate the available tags to keep them to a manageable number that is descriptive of frequently-searched topics.
