Hazed and Amuzed Posted May 25, 2008 Posted May 25, 2008 All liquids are water based then? Liquid does not equal water. Anything can be a solid, liquid or gas given the right conditions. Mercury is a metal and is liquid at room temperature. Other metals have very low melting points such as sodium which melts at 98 degrees celsius (208 Fahrenheit) and potassium which melts at 63.35 (145 fahrenheit) as opposed to something like iron which melts at 1,535 degress celsius. Your body temp is roughly 37 degrees celsius, water boils at 100. Given that liquid water can't exist in a vacuum and appears to be exceedingly rare in the universe why would we expect otherworldy beings to be water based? There are many elements on the periodic table that dont like water at all and will when put into water. If if one of these being happened to be comprised largely of an alkali metal I would say that water would be an excellent weapon. Since, in the movie, the aliens were able to touch people without instantly scalding them they'd have to be based in something like potassium. Other alkalis have much much more violent reactions and they would have not burned, but exploded when wet. A potassium based being could have in internal body temp of 145. Their external temp would obvioulsy have to be lower since they did have skin. Assuming 10 degrees (135 external) that creature could hold a person's bare skin for 15 seconds without burning them. Clothing would add to that time. Given that, you'd have to wonder why they'd choose a planet that is 2/3 covered by the stuff and has vaporized water in the atmosphere. Given all of that, dude, it's a movie. Damn. Now that's a response.
