In the very near future, a test is developed that incontrovertibly lets a person know who their soulmate is. The new science is clear, and no matter a person's current relationship status, whether they are single, dating or even married, this test will unmistakably point a person in the direction of their actual, scientifically determined soulmate. People in long-term relationships should not be content in believing they've already made the right choice. Even if a person seems to be deep in love with their current partner, this test may just prove that they are mistaken. After all, science knows best.
