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. I didn't say you did. You said "life as we know it". I just asked a general question concerning possible extraterrestrial life that may differ from "life as we know it", i.e. not carbon based, or on a goldilocks planet. As for what other elements do I think life could survive in, it depends what you mean by "life" .I know physicists contemplate different dimensions to the ones we recognise, so any possible "life" forms out there may be way beyond anything we can comprehend, living in elements we don't even know exist.

Cheers. The dimension thing is interesting charts,I'd tend to agree with you on that,but probably differ on what's in these dimensions? Different elements Different life forms Spirits/entitys Who knows? Edited February 15, 2021 by Francie Quote Link to post Share on other sites

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? There's a lot of evidence that there were ancient water courses on Mars, which would imply it once had a thicker atmosphere. Supposedly they have what looks to be evidence of thaw and freeze, happening today at the poles. 4 hours ago, kanny said: 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" This is something I find interesting and a lot seem to forget... The magnetic field that surrounds earth, is what actually allows life to exist. It protects Earth from solar and galactic radiation, not just keeps the atmosphere from being in direct contact with solar winds. So time spent living on Mars is pretty much limited, as it is on the space station. When you take into account the 18ish month return journey, time spent on Mars is probably going to be very limited. Seem to remember reading an article about the higher number of instances of cancers in the astro/cosmonaut community. I'll see if I can find it. 1 Quote Link to post Share on other sites

Cosmic rays are defined as "a highly energetic atomic nucleus or other particle travelling through space at a speed approaching that of light." if you need a deeper answer ask BH 1 Quote Link to post Share on other sites
Born Hunter 17,910 Posted February 16, 2021 Report Share Posted February 16, 2021 (edited) Radiation isn't an insurmountable hurdle for travel or a limited colonisation project. Shielding, reduced exposure times etc. Not to mention the long list of volunteers who just wouldn't care. I really do see habitation projects on Mars as a few steps down the line from space stations orbiting Earth. The first step really is a similar project on the moon. The technology can be tested more easily there. Once the financial viability of mars and the moon are established and the technology advances in the way that capitalism naturally encourages then I think the outer planets will draw much more interest. They're stunning and their moons probably have more potential. I wouldn't just envisage facilities on planets/moons either. I think space stations scattered about strategic points in the system are likely and could even be better than grounded facilities due to being able to create suitable artificial gravity etc. Edited February 16, 2021 by Born Hunter 2 Quote Link to post Share on other sites

Why mars anyway,is it cause the only other nearby an possibly habitable with big Arnie an three tits Quote Link to post Share on other sites

Radiation and charged particles are a massive hurdle. We can barely protect from radiation on earth aside thick concrete and lead. How do you think they will insulate an interplanatery ship, sufficient enough to have usable protection and be safe for 18-20months of space travel? How will they move the mass of lead up to the heavens and then propel it to Mars? (Newtons law and yes I know there is no friction lol) Quote Link to post Share on other sites
Greyman 31,759 Posted February 17, 2021 Report Share Posted February 17, 2021 The amount of shit you have to go through just for a week in Spain is more than enough for me, so mars can just remain an orange spec in the sky for, I,ll be happy if I make it down the Thames in me boat one day, all about sticking your flag in and claiming ownership and my money would have to be on the nips as things are at the mo Quote Link to post Share on other sites
