Ive discover something that would probably be a big no to the erudite scientist.

We know that earth is revolving around a certain unknown matter called orbit..
Its a big question to me what makes the earth floating ..in that orbit..
To begin with earth has a big mass AND also a big volume(because it has a big radius)..We know that density is mass over volume...lets take an analogy ...if mass is equal to 2 and the volume is equal to 1.9 the density would be smaller ....it would be less than one ...And by the bouyancy law it says that smaller density objects tends to float ..A needle would float in water ..and our body ..
