Is Gravity acting upwards or downwards?

[ErGingerbreadMandude]

To answer your question, gravity can pull up or pull down. It pulls towards the center of mass aka the center of the earth.

Ok,since i have no idea about how this thing works in the technical sense,can you think about it as,

Gravity doesn't pull towards the center of mass but rather push away from the center of mass?
And tell me if it makes atleast a least tiny bit of sense?

Probably completely stupid as fuck but,when i think about it,i think that maybe that's why we have an atmosphere.
Maybe gravity is pushing away from the center of mass?

But according to that,probably every planet with a really high gravitational field should have an atmosphere,right? Oh i donno about that
