scientist have worked out the maximum gravity humans could subsist on another world , if we were to scatter out into the world .
Publishing their findings on the pre - print serverarXiv , three scientists from the University of Zagreb in Croatia studied superintendent - land in fussy . And they found that our bodies could cope with about 4.5 times Earth ’s gravity .
To come to this conclusion , the team had a rather strange method , usingGame of Thronesstar and strongman Hafþór Júlíus Björnsson as a character study . They puzzle out out what soberness “ The Mountain ” himself would be able to stand firm , to estimate the upper limit potential for a man .
They first look at the gravitative military group that the human body could hold up , ferment it out to be about 90 times Earth gravity while standing still . For running , however , this dropped to about 10 time Earth ’s somberness before bones started to unwrap .
“ Skeletal strength is superfluous , however , if your sinew are n’t substantial enough for you to endure up or walk,”Discovernoted . “ ground on squat power , [ the team ] calculated that at five times Earth ’s gravity even an elite jock would n’t be able-bodied to move from a sitting situation . ”
This led to the psychoanalysis of The Mountain , who won theWorld ’s Strongest Man competitionin 2018 . He ’s about 2.06 meters ( 6 feet and 9 inches ) magniloquent and weigh more than 180 kg ( 400 pounds ) . And with all his strength , they found he could hold about 4.6 clip Earth ’s gravity .
For us more regular puny humans , that drop to about three to four time Earth ’s gravity . They do take down that with a spacesuit or other engineering it would be potential to withstand higher gravitational landing field , but that might not be ideal for long - term colonisation .
“ Our calculations did not integrate any suits or engineering , ” lead author Dr Nikola Poljak toldInverse . “ With those , you could increase the demarcation we forecast vastly . However , it would not be very practical to walk around in a spacesuit your intact life . ”
While interesting , the work is also important in terms of what planet we could regard genuinely habitable . thou of worlds have been found beyond our Solar System , some in the habitable zones of other planets , but many of whichare super - Earthsmuch more massive than our own .
“ [ I]t seems that , from the human perspective , the range of inhabitable satellite is much narrower than the kitchen stove of potentially life sentence - supporting major planet in the universe , ” the team wrote in their newspaper . “ This restriction arises primarily from sobriety , as the only environmental factor which we can not manipulate . ”
