Xavius
Xavius Watch this. You're conscious for up to 30 seconds or so, but an survive much, much longer than that. And if, say, you're a hypothetical organism designed to live in a microgravity null-pressure environment, you'd probably last many times longer. Almost like you're adapted to it.
yes i know i have already seen this.. by the way it is 15 seconds. an depending on distance etc. from rescue craft well your dead in those 15 seconds for all intentions and purposes. an yes you could live in space for a few minuets. that is not really surviving though.
Xavius and we're playing a game with spaceships breaking lightspeed
theoretically this is actually possible though. the problem is the power requirements.
Xavius and crewmembers running out into space without sealed suits
fair enough
Xavius Valves and decompression-resistant/immune membranes are on that list.
none of which saved the dogs in the video, or the deep sea fish when they are forced into shallow water, none of which will save the deep sea diving whales either in space. in fact they dont have valves and decompression resistant membranes what they do is they literally shift their entire rib cage and the deep sea fish dont have decompression resistance what they have is pressure resistant membranes which only work at deep sea depths hence why they die when they come up into shallow water.
Xavius This also assumes that the hide is made from a skin-like material, rather than say, a naturally-extruded silicone-based webbing over a base layer of nonporous tissue.
no; any hole created would KILL IT because of Delta P. again Delta P is the biggest killer of divers. for example lets say your diving into a pool or a water tower and need to do a check up on its health and etc. get too close to the drain the drain will suck you down and hold you there till you drown.
high pressure wants to go to low pressure. any hole created in the creature would be a death sentence because the blood and gases want to go to the low pressure area.
Xavius Actually, there could just be, y'know, two sphincters controlling valves. There's a lot of examples of this naturally such as in your own bloodstream. A mouth opens, encloses an area, closes the mouth, then uses magnetic organs to press the material inside together for easier moving onwards, where it's then broken down into its components.
none of which will save you from the rupturing of your lungs and suction when your body is exposed to space. the video you linked to even showed that.
Xavius And the Zerg have utlra-dense carapaces with no pores that let them function in a vacuum, and don't have to breed, as they can simply die and be consumed by other Zerg to make new Zerg from the biomass.
thats not exactly how zerg work; they dont create new zerg from bio-mass they do actually give birth. the zerg hatcheries and larva are literally zerg eggs. they breed asexually unless the guy who says "okay lets try this" says other wise (play heart of the swarm/evolution missions)
an no holes? hardly
Xavius Ergo, not applicable to this conversation.
okay
Xavius The better example would be the Tyranids, who use smaller organisms to 'net' free-floating materials and then consume the smaller organisms, manufacturing them anew as needed.
warhammer 40k is not very good with science you realize that right? there are "air" craft designed in such a terrible way they actually push themselves down and others which would literally act like you dropped a brick from the roof of a house the moment they entered the atmosphere. (an i can give you video links of a engineer with her own youtube channel with videos going through it all for you if you want)
anyways; again no any hole created would kill it. if anything went wrong or punctured it; it would die.
Xavius Hence why it uses a slow-moving but consistent method, such as the aforementioned gas-release method. It's slow, yes, but when your territory is measured in light-years and your lifespan in millenia, a few days accelerating towards the next food source is nothing.
yes it does matter; unless your body has a lot of fat your gonna find it a hard time to travel from gas spot number one to gas spot number 2 when they are separated by light years of distance without dying. for the sake of argument though lets assume gas spot 1 and 2 are separated by a full year; if they have the amount of fat a hump back whale does; they will only make it up to 5 months. less than half the journey.
lets assume gas spot 1 and 2 are separated by half a years worth. with the humpback whale fat your gonna be one month short.
okay so lets assume they dont travel to any other nebula; well than they are quite literally swimming in it but problem is every other space creature will be using that nebula as well.
Xavius Except they're in Nebulae, which are actually pretty bright, all things considered.
a nebula is NOT a source of light; all the bright colors you see etc.? that is from the gases reflecting light. a nebula is a collection of gases and dust. it is bright for the very same reason a bright red paper is bright red.
it does not matter how bright the nebula is; what matters is the light's wave length and what wave length the creature can take. for example plants dont just take in all the lovely photons they actually discriminate what photons of what wave length they take in. in other words they need a source of light. an yes some nebulas have stars inside them. their movement though will be restricted because if they move too far away from a source of light if they are photo-synthetic they will lose energy and be un-able to live.
Xavius Unless they have compartmentalized organs, like one might expect from something evolved in and developed for deep space survival. You seem to be comparing these titanic organisms to something like a whale or a human, which needs the environment its in to survive, but these would be a case of surviving in spite of their environment.
every creature/animal survives in spite of their environment. believe it or not the environment we humans are in does try to actively kill us. this is why we have evolved resistance against oxidation of our DNA and cells, this is why we evolved to be resistant against metal poisoning because iron will kill you in a sufficient amount and do utterly nasty things to your body. an we also use these materials as well.
every animal survives in spite of their environment.
