  1. I created the icons and set it up, but I didn't develop it. It's meant to be a quick basic look at things. AFAIK, there isn't any Moderation options unless you switch to a regular forum theme. Reason why it doesn't have much info is probably so it benefits text-based web browsing phones (usually non-smart phones cells). Sorry, I don't know how to fix it. Perhaps SCV or Fallen know.

  2. Yes. I'm saying that if life is possible at the volcano vents in the oceans, then it's likely it can be possible anywhere on Earth in most extreme conditions (Like Mt. Everest, Death Valley, Marina Trench, etc.). And with the Water Bear being resistant to vacuums, who knows. :D

  3. Show me the source to that... I would be glad to learn.

    Watch the Discovery Science Channel and you'll see it. If you are really as excited to learn about it as you implied, then Google. :\

    I just Googled right now and here are some links to save you half the time:

    Deep Sea Volcano Marine Life

    Physical conditions at vents

    tremendous pressure - 300 atmospheres

    extreme temperatures - highest measured vent temperature is 4030C, highest temperature at which living tube worms have been observed is 1000C, sea water is about 20C at depths where vents form, but can be up to 200C near some vents.

    chemicals - hydrogen sulfide, the source of energy that fuels vent food webs and the most plentiful compound in vent emissions, is toxic to most living things.

    pH - vent fluid is very acidic with a pH as low as 2.8, which is very unhealthy for most living things.

    Don't tell me that isn't extreme. lol

    The one about creatures living below the ice may be harder to find since it was probably a long time ago.

    Another creature: The "Waterbear". Link and another link.

    In the 1920's P. G. Rahm of the University of Freidburg discovered tardigrades were able to withstand being heated for a few minutes in 151 degrees Celsius and survive being chilled for days in temperatures up to minus 200 degrees Celsius. While in this state the organisms are also greatly resistant to ionizing radiation as shown by Raul M. May from the University of Paris who found that 570,00 roentgens were required to kill 50% of exposed tardigrades (only 500 roentgens would be fatal to a human). Water bears are also resistant to vacuums. Specimens exposed to high vacuum and electron bombardment in a SEM for 0.5 hours were then revived and survived for a few minutes before dying.

    Google "Tardigrades" for more info.

    Merry XMas.

  4. Past-Life on Mars may have been possible. Yeah, there is toxic chemicals, hardly an atmosphere, etc., but recently discovered were these sea creatures living near the marina trench that only lived off of the gasses from volcano vents spewing out sulfur and other chemicals. They were creatures like crustaceans, tube worms, and a few species of fish. Scientist and researchers also thought it was impossible for living things to exist under ice sheets in extremely cold regions on Earth, but they were discovered eventually. There is many weird things on Earth. There is also a forest where all the animals, appear miniature.
