Whilst very massive stars (VMS) with 100+ solar masses have been claimed to exist in the very early Universe, possibly causing Cosmic Reionisation, recent studies have suggested the existence of stars up to 300 solar masses in our local Universe, which came as a surprise to many workers both inside and outside the field. These massive beasts are also thought to be the objects that collapsed into "heavy" Black Holes that were recently discovered through Gravitational Waves. I will discuss the life & deaths of VMS from a theoretical point-of-view, before testing these theories against observations from the VLT-FLAMES Tarantula Survey and LIGO.
