Black Holes Neutron degeneracy pressure cannot support neutron star having mass 2 to 3 solar masses Collapses Gravity is so strong that nothing can escape, not even light compress material to such a small volume that the escape velocity = speed of light o escape velocity = minimum initial speed of object that can escape to infity o R< R S =2GM/c 2 Schwarzschild Radius, R S o Example – R S = 3 km for sun o Spherical surface having R = R S is the event horizon of a Black Hole o Matter inside the Black hole continues collapsing to a mathematical point called a singularity Photon near a Black hole o light is trapped inside Black hole due to the effects of general relativity o light is coming from a region close to, but outside, a black hole is bent and redshifted o the photon sphere : light can orbit a black hole at a radius of 3Gm/c 2 1.5 times the Schwarzschild radius, R S Tidal forces near a black hole o near a low-mass black hole the tidal forces are much larger than those near
