"Monsters, Inc.'s main duty is to provide all citizens in Monstropolis with energy in the form of captured screams collected from children. They accomplish this by crossing into the human world through the closets of children's bedrooms and scaring them to the best of their ability. The screams are then collected in special canisters for use as energy."

"Their job is to go through portal doors (that probably go into the past) and scare little kids. It turns out that scared humans are a means of producing energy."

"Children, the world over, are terrified in their beds in order to create consumable energy stores by harvesting their screams."

"Stephen Hawking and other physicists suggest that negative energy is required to stabilize a “traversable wormhole,” an entity that would allow a person, object, or information to travel between two points in time or space."

"Physicist Michio Kaku doesn't entirely rule this possibility out, but he cautions that powering a time machine to travel in this way is beyond human capabilities right now, and would demand either negative energy or the energy of a star"

"While this kind of negative energy happens on a quantum scale, piling up enough in the form of 'negative mass' is still a realm for exotic physics."

"If this negative mass/energy matter exists, then creating both a supermassive black hole and the negative mass/energy counterpart to it, while then connecting them, should allow for a traversible wormhole. No matter how far apart you took these two connected objects from one another, if they had enough mass/energy — of both the positive and negative kind — this instantaneous connection would remain"

"Bob Lazar stated that the “Sport Model” Flying Disc amplified the “Strong Nuclear Force” of Element 115 (UnUnPentium or UUP, currently named Moscovium) to generate the gravity field for “Space-Time Compression.” Bob also stated that the U.S. Government had 500 pounds of Element 115 in their possession."

"Lazar further explained in his interviews that bombarding Element 115 with protons leads to it creating Element 116 (Livermorium) which immediately decays and produces antimatter. The antimatter collides with normal particles creating a massive energy burst, which can be used for propulsion. It’s quite likely Element 115 could also be the famed exotic matter that is needed to create traversable wormholes that physicists such as Drs. Kip Thorne and Carl Sagan have speculated, and was the subject of a recently leaked Defense Intelligence Reference Document titled “Traversable Wormholes, Stargates, and Negative Energy” ."

"antimatter is an extremely dangerous substance with immense destructive potential, which is unleashed upon contact with any form of normal matter, and is comparable to a small nuclear weapon.
In the story, scientists have solved one of the most complicated scientific problems: the capture and storage of antimatter. In the real life, capturing atomic antimatter has not yet been achieved."
