Question:
Electromagnetism can attract and repel because it has two
charges. Gravity is only known to have one charge: mass. But if negative
matter or negative mass exists, them you would know that gravity can
attract and repel just like the electromagnetic force. Would the
discovery of hypothetical negative matter help us unify electromagnetism
and gravity?

Seems logical.
But it might be that there is not just one force.... perhaps two unrelated
forces... EM and gravity.
One other problem. If all matter that we now know is positive matter, why
does each mass not repel each other mass? If each body carried a like
electrical charge that would be true. Instead, all mass attracts all other
mass.
