From what I'm reading from NarutoForum.com, the Tenseigan to the Byakugan is like the Rinnegan to the Sharingan. Basically, like how one has to steal another MS Sharingan (EMS) and combine it with Hagoromo's 2 bloodlines (Indra and Asura) to get the Rinnegan, Toneri took Hanabi's eyes, and combined it with Hamura's two bloodlines to get the Tenseigan, which are said to have enough power to destroy the Earth.
