I guess

All tachyons have negative energy and negative momentum.

There is repulsion between some positive energy particles.

The positive energy particles emit a force - tachyons. Like an
electric field. The tachyons that make up an electric field have a
charge - the charge emits a force. This is the force between 2
electric fields - attractive and repulsive. When there is an
attractive force between 2 electric fields - the tachyons emitted by
the electric fields will have negative momentum. Tachyons with certain
speeds - can look like they are positive energy and have postive
momentum to some tachyons - they all look like negative energy
particles to positive energy particles - negative momentum. With
attraction of an electron and proton - there is attraction between the
electric fields - the forces between the electric fields will have
negative momentum for the electric fields. With repulsion - the forces
between the electric fields will have positive momentum for the
electric fields - when particles that make up the electric fields - are
hit by forces between the electric fields - the forces will have
postive momentum for the electric fields - if forces between the
electric fields hit a positive energy particle - the postive energy
particle would see negative momentum.

All tachyons have negative momentum for positive energy particles - if
those tachyons hit positive energy particles. Tachyons can see
positive momentum created by tachyons if the tachyons have certain
speeds.

All of this applies to all forces - gravity - anti gravity - electric
fields - magnetic fields - strong force - weak force. All forces have
a charge that emits particles - like an electric field has a charge and
the charge emits a force that creates attraction and repulsion between
electric fields. Gravitons have a charge that emits a force that can
create attraction and repulsion between gravitons.

God has cursed all my theories.
