Nature's Four Forces
Of course, nature's four forces (electromagnetism, weak, strong, and gravitational) do not act exactly alike on both ordinary and mirror matter. Each force is expected to be doubled (i.e. ordinary electromagnetism has a mirror electromagnetism partner which acts on mirror particles), with the exception of gravity. Since Einstein's theory relates gravity to the space-time continuum, of which there is only one, everything should be under the same gravitational force. Thus mirror matter and ordinary matter only interact via the gravitational force.
