The Silence

The Voice (also The Silence) describes an unknown, but powerful external force that forced the Doctor's TARDIS to explode on the date of June 26th 2010, and thus created the Cracks that would erase various things throughout the universe, and eventually the universe itself.

When it first took control of the TARDIS, the entity forced the TARDIS to land outside of Amy Pond's house on June 26th 2010, and began to explode shortly afterwards, trapping River Song inside of it, where she was put into a timeloop as the explosion happened continiously at every point in time until the Doctor saved her. Although the entity behind the voice was never visible or named, it was heard to be speaking before the TARDIS exploded, saying: "Silence will fall!" (DW: The Pandorica Opens/The Big Bang)
