High Energy Collision of Particlesabove the Planck scale:gravity is dominant interaction⇒ classical descriptionConsider particle collsions with E = 2γm 0 c 2 > M PlHoop - Conjecture (Thorne ’72)⇒ black hole formation, if circumference of particle < 2πr SCollisions of shock waves (Penrose ’74, Eardley & Giddings ’02)⇒ black hole formation if b ≤ r Snumerical evidence in ultra relativistic collision of boson stars(Choptuik & Pretorius ’10)⇒ black hole formation if boost γ c ≥ 2.9⇒ black hole formation in high energy collisions of particlesH.
