I am a bit dumb, and don't know how to spot problems with studies, so can someone else look over this study that my dad sent me, and see if there is anything wrong with it. https://pmc.ncbi.nlm.nih.gov/articles/PMC10531689/
I need this because my dad thinks that it can cure cancer, and is not toxic.
Point one: satellites being lifted by balloons. The ISS weighs about 450 tons, so you would need about 420k cubic meters of helium to lift it, and I do not see a balloon in this video www.youtube.com/shorts/3RvhoNB4l2k
Point two: 17000mph is so fast, how do they not just get left behind. On Earth the air is there to slow you down, but in space nothing slows them down thus they keep going 17000mph alongside the ISS.
Point three: It is way too hot up in the thermosphere. Put your hand in boiling water, and then in the oven, even though the oven is two times hotter it still hurts less, and that is because the air in the oven is less dense then the water, and thus will transfer heat slower. And the thermosphere has extremely little air to transfer heat.
Point four: You can not even see them from the ISS. They are just really far away and and small.
Just in case anyone is dumb enough to fall for this, then look up the cavendish experiment, and If it was density everything would go up, because the air above you is less dense then the air bellow you, and if you do not believe that, then go to the top of Mount Everest, and see how easy it is to breathe.
