However, in the description of black holes predicted by relativity, once information passes the event horizon, it is unable to exit the black hole due to the warping of space-time by gravity. A black hole radiates Hawking Radiation, causing it to decrease in size and eventually disappear. This is called the black hole Information Paradox. The theory proposed by some physicists to resolve this paradox, “complementarity”, states that observers viewing the black hole from outside will see the information at the event horizon then return back through the Hawking radiation, while observers inside the black hole will see the information inside the black hole itself. There is no paradox in this explanation as the two observers are unable to communicate to each other. There is so much interesting physics surrounding wormholes and black holes, and it is no wonder that they remain big topics of research and academic debate to this day.ġ. ![]()
