Powers and abilities
Jon is the only character in Watchmen to possess superpowers. Throughout Watchmen, he is shown to be absolutely powerful and invulnerable to all harm; even when his body is disintegrated, he can reconstruct it in a matter of seconds and remains unharmed. He is capable of altering his size depending on his needs, for example, reconstructing himself in a much bigger form. He can hurl huge objects effortlessly with his hands. He is also unable to exhaust himself. Jon has complete awareness of and control over atomic and subatomic particles. He is also an omnikinetic. He does not need air, water, food or sleep, and is immortal. He can teleport himself and others over limitless distances. He is also capable of true flight, although he uses only levitation in most of his appearances. Due to his perception of time, he sees his past, present and future simultaneously.
In addition to these powers, Jon is able to phase any part of his body through solid objects without damaging them, produce multiple copies of himself which function independently of each other, project destructive energy, disintegrate people, create force fields, transmute, create and destroy matter, move objects without physically touching them (telekinesis), reverse entropy, repair anything no matter how severe the damage is, and, he suggests, create life. He also claims to have walked on the surface of the sun. At one point it is stated that, in the event of a nuclear war, he would be capable of destroying Soviet nuclear missiles while at the same time 'destroying' large areas of Russia. As a result of these capabilities, Jon becomes central to the United States' Cold War strategy of deterrence.
He is also capable of manipulating reality as he sees fit, as seen when he erased ten years from the DC Universe, when Barry Allen tried to bring his original universe back to normal. The intervention of Jon caused The New 52 timeline to be formed, within which most superheroes are younger and less experienced, and most of them lose their most important relationships before they even begin. Even Mister Mxyzptlk himself acknowledges Jon to be far more powerful than him. Such power makes him one of the most powerful beings in the DC Multiverse.
In the 2009 film adaptation Watchmen, physics professor James Kakalios of the University of Minnesota was used as a scientific consultant, and shed light on the potential scientific explanations of Doctor Manhattan's powers both in the film and the comic. Cherenkov radiation inspired Doctor Manhattan's appearance in the 2009 film adaptation.
Kakalios explained that the intrinsic field has basis in reality in that it is a representation of a collection of the electromagnetic, and strong and weak nuclear forces. Kakalios explained that if a being were able to manipulate matter, such a being would have complete control over these three forces; hence, the "intrinsic field" would exist. Kakalios also explained that while it is unlikely, Doctor Manhattan's teleportation abilities could seemingly be achieved through quantum tunnelling, should Doctor Manhattan have control over his probability wave functions.
Basically my God is similar like him and I want to know is there a way to contain or trap something like him.
Please explain the method to achieve it, even better if it can be done or create by human, it's not necessary using today's technology, but at least achievable in the future or might be theoretically possible.
