A falcon-shaped jet flew over the school city, and a moment later it had rushed over the second new New York, which was a large part of the second new New York.

The Falcon, once part of the X-Men, slowed down, and the vector-powered steering system under the wings gently adjusted the high-velocity gases, allowing the plane to hover in the air like a helicopter.

Thor, Rockie, Captain America, Black Widow and other four people jumped off the plane and smashed on the roof of the Stark Building, followed by some school city insiders - such as Magneto, Professor Charles, Brother Mao, etc.

As soon as Rogie got off the plane, she didn't care much, and with a wave of her scepter, she lifted her mind control over Hawkeye, Dr. Servig, and a group of S.H.I.E.L.D. agents, and walked straight to the instrument, looking back and forth.

Professor Charles and Magneto, as Lyceum City technicians (they once worked together to build a cerebral amplifier), also walked back and forth around the instrument.

"Einstein-Rosen Bridge?" Professor Charles looked at the Cosmic Cube in disbelief and whispered.

"It should be." Magneto nodded, looked at the extremely narrow pillar of light in the sky, and said nothing.

"What?" Captain America put the shield behind his back, frowned, and said, "I'm sorry, can you explain specifically?" ”

Magneto glanced at him lukewarmly, and said casually: "The Einstein-Rosen Bridge refers to a hypothesis put forward by Einstein and Nathan Rosen in 1930 when they were studying the gravitational equations, and they believed that rapid space-time transfer could be carried out through wormholes.

At the time, however, even Albert Einstein himself did not take this theory seriously – he believed that the gravitational pull of black holes was strong enough to destroy all matter.

However, in 1963, according to the research of New Zealand mathematician Roy Kerr, it was found that when a giant star collapses due to fuel consumption, it will resist part of the gravitational pull due to the reignition effect, which makes the collapse effect incomplete.

That is, the star will be transformed into a flat structure, rather than simply forming a singularity. ”

"Uh, what does that mean?" Captain America asked with a frown.

"This means that the gravitational field is not infinite."

Rocky, who had long straight black hair, suddenly raised her head and said, "As long as you put the object into the center of rotation of the rotating black hole, it is likely to survive the capture of the axis gravity field, pass through the black hole, and fall into the mirror universe far away. ”

Everyone was startled and stared at Rockie in disbelief, wondering how Rockie, who came from the magical country of Asgard, could understand human science.

"What do you see? Asgard's technological capabilities are also far ahead of humans. ”

Luo Ji frowned, and said to Thol, who was also surprised, and said: "Brother, we use the Rainbow Bridge to travel through the Nine Realms every day, don't you know that our Rainbow Bridge in Asgard is also based on the Einstein-Rosen Bridge principle?" ”

"What?" Thor looked dazed, stretched out his fingers and scratched his rough chin full of stubble, and smiled innocently, "There is such a thing? How did I not know? ”

Lockie looked at her bear-like brother and couldn't help but cover her chest, saying in her heart, 'Such a stupid person is actually my brother, fortunately I am not related to him', but still said patiently: "You recall carefully, is the temple guarded by Heimdall resembling a spinning top?" That place is the Axial Gravity Field.

The Rainbow Bridge is a barrier that protects pedestrians above from being captured by strong gravitational forces. ”

"Hahaha, is there anything else going on?" Thor smiled happily and said heartlessly, "Then our Asgard is really amazing." ”

"You are smiling, as the prince of Asgard, the heir of Odin, and the future guardian of the Nine Realms, your words and deeds are so unintelligent, which even more contrasts with the black humor that I can't be a king."

Rogie complained frantically, and his gaze at Thor became more and more unkind.

"That's right, the function of this instrument is to turn on the ability of the Cosmic Rubik's Cube, and use the Rubik's Cube to displace negative energy from the pocket space to stabilize and expand the black hole."

After being exposed to mind control, Dr. Servig immediately reacted to how much trouble he had caused and said regretfully: "Just like the movie "Interstellar", the dynamic black hole in the steady state will be perpendicular to the original space-time at the edge of its Schwarzschild radius, which means that the black hole horizon is combined with the conventional cosmic space.

That is, Schwarzschild throat. ”

"I'm sorry."

Among all the transcendents present, Captain America's education may only be higher than that of Brother Gang and Brother Mao, but in order to understand the situation on the scene, the Avengers leader still stubbornly said: "Dr. Servig, I can understand every word you say, but when combined, it seems a little obscure.

Can you explain a little bit more? ”

"Okay, okay."

Dr. Servig looked at the nationally famous super soldier and said with a wry smile, "The Schwarzschild radius is the critical radius of any mass with gravity, which is an exact solution of the gravitational field of a spherically symmetrical, non-rotating object.

When an object with mass is smaller than the Schwarzschild radius, it is a black hole.

The Schwarzschild radius of the Sun becoming a black hole is 3,000 meters, which means that the entire mass of the Sun is compressed to a diameter of 3,000 meters, and it will become a black hole.

The special feature of the Cosmic Cube is that it can extract negative mass, create black holes out of thin air, and keep the black holes in a stable state. ”

"And what can be done to destroy it?" Captain America asked bluntly, "At least stop it." ”

"There is no way."

Magneto took over the conversation and said with a gloomy face: "It is the Cosmic Cube that creates the black hole and provides enough negative mass for the black hole.

It's like an animal trainer feeding the greedy tiger Black Hole. ”

"What do you mean?" Team America asked.

Professor Charles sighed and said tiredly: "Look up, soldier, the Schwarzschild throat in the sky is constantly expanding, and if you try to interrupt it, it is equivalent to stopping the animal trainers from feeding the tigers,

The end result is that the hungry tiger of the Black Hole can only plunder all the food it can from its surroundings.

The black hole's horizon will expand indiscriminately in search of mass to keep it going, and our Earth will be absorbed in a second, and everyone will die. ”

Speaking of this, Professor Charles smiled miserably and said lightly: "The only good news is that we died not so painfully. ”
