Francie 6,368 Posted February 15, 2021 Report Share Posted February 15, 2021 Was watching a wee show last night,an they were debating it. Was it habitable in the past? Will it be habitable in the future? This should be fun,bita craic I'd say no,on both questions,its too far away from the sun to maintain life as we know it. Was it closer or further away in the past? Science says no? Quote Link to post Share on other sites
Born Hunter 17,910 Posted February 15, 2021 Report Share Posted February 15, 2021 Dunno about the past, don't really care tbh. The future though, yes to colonies living in biodomes, no to a fully terraformed habitable planet. 1 Quote Link to post Share on other sites

You mean like total recall born lol Are they really trying that,what's the point of it all,exploration? Quote Link to post Share on other sites

Was it closer or further away in the past? Science says no? Does does it have to be "life" as we know it ? Why do we think "life" needs to be carbon based and can only live on a "goldilocks" planet ?

kanny 21,687 Posted February 15, 2021 Report Share Posted February 15, 2021 Pointless terraforming Mars, it has no active core generating a magnetic field to protect it, meaning any atmosphere gets stripped away by the solar winds, we can see the effects of earths protection its the northern/southern lights, high energy particles from the sun that would strip our atmosphere are deflected by the magnetic field, unfortunately for Mars it was too small and cooled too quickly, the only way for us to survive on Mars would be in some sort of bubble, i don't doubt we will have a small colony of scientists living on mars in the near future but id hold off booking a holiday there for now "smaller objects cool more quickly than larger objects of the same shape because they have proportionally more surface area to cool" 2 Quote Link to post Share on other sites

Like total recall and about a million other sci fi films, shows and books. Lol I don’t think it’s technically possible to turn Mars into another earth. It’s gravity isn’t strong enough to hold sufficient atmosphere. I think it’s an inevitability. Exploration for one. But I think it’ll be profitable soon enough. Space is now an accepted commercial domain and even a war fighting domain. It’s big business and the technology is racing off to keep up. I believe we will have colonies all over the system to support commercial and scientific operations. Mining, tourism, science, war will all drive this new space race. Mars is just a part of it. 1 Quote Link to post Share on other sites

What I meant by life as we know it,is that what we see on earth,observable humans animals insects,was like that in the past,that what I was asking. Depends what you call life? What other elements do you think life could survive in? Seen on the ocean floor theres sulphur chimneys spueing out,an the big worms an stuff,scientists thought that nothing could live in those conditions,but there ye are.
