According to CNN, astrophysicist and author Neil deGrasse Tyson has denied allegations of sexual misconduct made against him by three women. The women claim Tyson harassed them and made inappropriate sexual advances back in the 1980s and in recent years. In a Facebook post, Tyson wrote, "Accusations can damage a reputation and a marriage.
