• He literally said: "Let me give you an analogy..."﻿

• It bents because gravity distorts (curves) space itself. Light just follows the straightest﻿ path possible, the so-called geodesic. If gravity is null the geodesic is a straight line, so light travels in a straight line, in the vicinity of a black hole gravity is very strong, so spacetime is strongly curved, so much in fact that all world lines point to the black hole's singularity.

• Light doesn't bend; the space in which it propagates does. A black hole is a region﻿ of spacetime so distorted that you could say that every direction becomes "down". Gravity never reaches a zero-value either, so if you can see it, then you're experiencing some degree of gravity from it. Even if that value is infinitesimally small.

• I got your big mass right﻿ here!!!

• We all go﻿ Super Saiyan

• Michio Kaku, someone give﻿ this man a medal and some wine!

• I need﻿ that t-shirt.

• Okay, thank﻿ you for answering my question.

• That is a sweet shirt!!﻿

• But WHY does a topquark acquire mass when entering the Higgs field? The man doesn't tell us WHY. Since e=m.c2, m=e divided by c2. Well, the bossons are just energy. When the quark collide with bossons, it slows down its speed and those opposing energies (quark vs.bossoms) BECOME MASS, which is added to the quark. Look﻿ at the ecuations: if c2 diminishes, m increases! Why didn't he tell us THAT instead of giving bad examples in which the people on the snow KEEP ON HAVING THE SAME MASS?

• Can somebody please explain to﻿ me why if light has no mass, then how is it bent by a black hole's gravitational pull?
