Reset level when a moving object collides with a player?

Hey i'm sorta new to scripting and unity. I was wondering if there was a way I could reset the level of my game when a moving object hits the first person controller from any direction the player is facing. In the game the player runs down a corridor whilst being chased by a large spherical object and has to escape before he gets 'crushed' by the object. Kinda like Indiana Jones.
