as newton predicted the escape velocity thingy.. if and object has a suffecient enough escape velocity it can go around the earth.. but now we no thats not possible because the object will descentegrate in the atmosphere.. well i wanted 2 no that is there any object with can travel in an atmosphere without being decentegrated by the friction created by air resistance?

Escape velocity is not the velocity to send something into orbit, rather to escape the gravitational field.

Light doesn't according to our calculations slow down and decentegrate but is deflected by gravitation. I assume you are talking about practical objects, that we can use, then the answer is no.

what do you mean by "that's not possible"?
you just cover the object with something you dont need
like ablative shields

whats ablative shields? sci-fi stuff?

They are the heat shields that are used on space craft, to disapate the energy as objects travel through the atmosphere. They however dissipate energy, so yes they do still result in a lowering in orbital velocity and decrease in radius of orbit.
