| Aug 24, 2018 at 8:21 | comment | added | D3f4u1t | Thank you @M. A. Golding. My storyline doesn't tell the whole story of that alien race, but from a individual alien organism coming to earth. Maybe this alien was on a discovery mission to find more habitable planets. That way it got to earth. But at the time it arrived, it met the first human-like animals, gave them consciousness and thaught them how to walk straight. I want to tell the story of Adam and Eve in a more science-fiction way... | |

And thus if a disaster threatens their entire home solar system, they can seek refuge in already colonized solar systems and explored but as yet un colonized systems. And unless they have a faster-than-light drive their starships will have to keep them alive for decades, centuries, or millennia, and they will have a proven ability to create livable environments in outer space or space habitats. | |
| Aug 23, 2018 at 17:14 | comment | added | M. A. Golding | @D3f4u1t I find the premise that the alien world would be more advanced than 21st century Earth for many hundreds, thousands, or millions of years, and then suddenly develop interstellar travel when their home world is threatened, and seek to migrate to Earth, is deeply flawed. If they are anything like Earthlings they would gradually explore and colonize other planets in their solar system, and build space habitats, and eventually have thousands of times as many people in space as on the home planet. So if a disaster threatens their home planet, they can seek refuge elsewhere... Continued | |

| Aug 23, 2018 at 13:11 | comment | added | D3f4u1t | Sorry for beeing that unclear. This is my very first question :) I wanted to set this story in a time, where homo sapiens were about to evolve and neanderthal still existed. Well the plot of my story is: What if god (as we know it from our religions) is in fact an alien? That's the reason why this alien shouldn't wear a pressure suit when beeing on earth. | |

| Aug 23, 2018 at 12:54 | comment | added | D3f4u1t | the question states that an organism would need pressurized air supply. But only if it doesn't have the ability to adapt to the environment. This alien organism is able to control 1. heartbeat frequency and 2.blood pressure. My question is: Does it still need a pressurized suit to survive our conditions on earth? | |
| Aug 23, 2018 at 12:53 | comment | added | L.Dutch♦ | @Battle, Venus has similar gravity to Earth, 0.95 g, but much higher surface pressure, 92 atm. | |
| Aug 23, 2018 at 12:52 | comment | added | MichaelK | You decide, you are the author. You have already designed this creature to be quite Earth-like in its metabolism in that it breathes and has a heart-driven circulatory system for oxygen. So ask yourself the opposite: is there anything in your design that 1) is absolutely necessary to the narrative, that you cannot, under any circumstances trim away and 2) makes it impossible for this thing to survive on Earth? If the answers are 1) no, 2) N/A or 1) yes, 2) no... then you have answered your own question. | |
| Aug 23, 2018 at 12:51 | comment | added | Battle | Why would the answers to the second question you linked not be fitting? @L.Dutch - It appears like gravity and atmospheric pressure correlate highly, meaning it would be also roughly ~3 times as high as well. It would have been my first question as well, but I took a minute to look it up. ;) | |
| Aug 23, 2018 at 12:50 | comment | added | D3f4u1t | The home atmospheric pressure is 3 - 4 times higher than on erath depending on the actual gravity | |
| Aug 23, 2018 at 12:47 | comment | added | L.Dutch♦ | What is their home atmospheric pressure? | |
