Why do helium baloons float?
According to my theory I said the gravity is second production of the earth when the earth turn over it self it cuts some Fieldds look like magnetic field so this fiel when any things turn into it can let it make private electronic field and even the field some kind of electronic so the Helium as single atoms has privet movement or turning this movement created same field just that created on the earth and defiantly the same field cant attractive them self and then you get it floating over over into the sky and if the powers of helium field is biggest than normal you cant see helium on the earth at all. This analysis you can apply it for all gas and why some material heavy and some is have light weight.
