Is gravity only electrostatic attraction?

A recent article about gravity and antigravity proposed earth as a mass with contains a huge charge. Every object (no matter if metal or isolator) with lower charge is attracted to objects with greater charge. That's why everything falls onto the ground. A small ball on the table is attracted to a large ball on the same table. But both bodies contain too less charge to overcome the attraction to earth.

(On a side note, this could naturally explain, why small girls feel attracted to big men, and small men to big women.).

Joking aside... let's say earth would somehow lose it's charge instantly, then it would lose all its gravity, causing people to fly away in all directions. It also fits to the moon. If we look at it, it looks dead, it is dead... it seems to have lost a lot of its charge. And therefore attraction is lower.

Edit: on second thought I can't explain the following: you can make light materials (e.g. paper scraps) fly through the air towards a charged plexiglass ruler. How can that happen if earth attraction is stronger? Is it because the "charge density" in the immediate local environment is stronger than earth's attraction?

Edit2: Franklin Hu talks about this matter much more clearly in a paper and also got a youtube channel.

This was an interesting article: http://franklinhu.com/NPA20GravityElectric.pdf

He also tries to explain in chapter 5 why we don't get electrocuted by the earths' charge when we touch it. Of course there's a lot more to research...
