Is wormhole travel really possible?

In 2022, Netflix released a sci-fi movie called Project Adam. Set in 2050, the world is firmly under the control of a high-tech company. Adam uses the company's wormhole technology to travel back to 2018 to rescue his wife on a mission at that point in time, only to stumble into his own home in 2022 and meet his teenage self. Then the Adam and the young Adam through time to change the future together, along with the resolution of a father and son estrangement. The movie's gimmick is wormhole penetration, in which aircraft disappear as if teleporting, leaving enemy aircraft in pursuit frozen.

immediately closes, and the orbiter comes out of the wormhole at another exit. I'm not going to talk about the theory of time and space in time travel today, it's too complicated, but I'm going to focus on impulse as a way of traveling across light years. Actually, today's episode is about how Ufos travel across the vast galaxy.

To sum up, it is not complicated. There are only two categories. One is the active flight mode of the vehicle with its own power, such as superconducting electromagnetic power, light sail power and plasma thruster mode, which is relatively close to our current space travel mode. For example, the plasma engine and light sail power, which are in the experimental stage, are also relatively easy to master for the lower level of intelligence in the universe.

The second category is one that works with warping space-time, or what you might call passive flight mode, like warp drive theory, which compresses the space in front of the vehicle, the vehicle doesn't move and the space moves. Similar to the Chinese Taoist method of shrinking the land, the old way is walking slowly in front, and the people behind can not catch up with them. Some reports of UFO sightings talk of a UFO speeding up in the blink of an eye against the laws of physics, akin to the use of warp drive. Today we're going to do something even better, a second category of passive flight, which cuts a wormhole through space and time, a form of space travel we might call a wormhole engine.

If there is a noticeable difference between the two modes of travel, it is that the warp drive appears to the eyewitness as the mysterious acceleration of the flying saucer, while the vehicle enters the wormhole as it disappears in our space and flees into another space. A wormhole literally means a worm's hole, so how can a worm's hole travel across light years? Let's start with what a wormhole is.

The concept of a wormhole was coined by Albert Einstein, one of the most famous physicists of the 20th century, who explained it this way: a star has a web of space-time around it, and the more massive the star, the more distorted the web. A particularly large star collapses into a White Dwarf as it dies, and then goes on to become a neutron star, eventually becoming a black hole. After becoming a black hole, he will become a big stomach, all the time on the show of eating, swallowing everything, stars, light, as long as it is close to it, all will be eaten by it, in and out, only eat not pull.

Whatever you eat becomes the mass of the black hole itself, and it gets heavier and heavier until space-time can no longer hold its mass, tearing a big hole in the space-time web with a squeal. But we're not done here. Einstein and his student Rosen have yet another round of calculations to tell us that this piece of space-time torn apart by a black hole will eventually join up with other space-time as a wormhole. Once you're in this wormhole, you can travel through it magnificently. Because Einstein and ROSEN WORKED it OUT TOGETHER, THE wormHOLE'S OFFICIAL NAME IS THE Einstein-Rosen Bridge.

Physics gurus tell us we can travel through vast Spaces through wormholes, but how do you think wormholes come from? It's a tunnel from a black hole, which means it's nested inside a black hole. So you want to go back in time? Yes, you have to go into a black hole first to feel the wormhole, but do you dare to go into a black hole? It's a scary thing to think about.

The reason this sounds particularly scary is not because anyone has actually tried to drill through a black hole, but because of scientific assumptions. Until the 1960s, classical black hole theory held that the center of a black hole was a collapsing singularity with infinite gravity, and anything approaching it would be pulled in by it, crushed into a thin sheet of paper, and broken down into subatomic states. Is that guy gonna survive in there? So no one dares to dream of traveling through a wormhole.

But the complication is that there are all kinds of black holes, and they don't all look the same. Then, in 1963, a physicist named Kerr discovered a kind of rapidly spinning black hole, scratched his head, and quickly worked out a long list of formulas on the blackboard. Suddenly, what if it was a black hole spinning really fast? Then its center would not collapse into a singularity, but a rapidly rotating ring.

If the person who falls into the black hole passes right through the ring, it won't be crushed into paper. But then the question becomes, if you can pass through a black hole unscathed, where does it come out? Kerr thought hard. Suddenly, he saw a black and white picture on the wall, black with white, very bright, good-looking and easy to remember, it is called the white hole.

So today, scientists think that whatever goes in from a black hole will theoretically come out of the white hole as it is, but where the white hole is is uncertain. It could be in a parallel space-time, or in a parallel universe, or it could be at a different point in the same universe. Well, wormholes could theoretically allow us to travel across time, over distances of light years. But the question is how? People are racing to find answers.

Then, in the 1980s, Nobel laureate Thorne, another big name in physics, finally came up with an answer. He said slowly that if a few of these problems could be solved, we humans could travel through time. Which problems to solve? It takes a huge amount of positive energy to create a wormhole in the first place. The second is that once the wormhole is formed, a huge amount of negative energy or matter is needed to hold the tunnel and keep the central ring spinning fast enough.

Negative energy refers to the negative energy produced by balancing quantum fluctuations in a vacuum. Negative matter is not antimatter. Negative matter is matter with negative mass, while antimatter is also something with positive mass. Everyone was dumbfounded. What you said is not equal to nothing? Where do I find duplicate negative energy? These guys aren't kidding, are they? So everyone just raised the mood is put down. Therefore, although the wormhole technology is feasible in theory, it is impossible to realize it in reality due to the fact that negative matter has never been found and negative energy is very small in the universe.

Some people immediately remember that UFO witnesses often say that Ufos suddenly seem to disappear from our space, which is too similar to the wormhole flight in the movie Project Adam. There was a gasp. What kind of civilization could create a wormhole flying vehicle? Michio Galai, a theoretical physicist, believes that a civilization that can harness wormhole technology would have to reach at least level three on the Kardashov index. One of the technologies of the third level of the universe is the ability to build stable wormholes for time travel. How do you set it up? Is to master and use Planck level energy. What is this Planck level of energy?

What is the maximum energy that the Hadron Collider at CERN, the most powerful particle accelerator on Earth, can produce? Fourteen trillion electron volts, and Planck-scale energies are a quadrillion times that number, which is a trillion quadrillion electron volts. What is a trillion, billion, billion, billion? The number is not the point, the point is the result, gravity at this level of energy completely collapse is remarkable.

As you know, there are four basic forces in the universe, gravity, electromagnetic force, strong force and weak force. Can make gravity do nothing, and congratulations, you've gone beyond the rules of the universe. The Planck level of energy is at the level of the Big Bang, and at the center of a black hole. Because it is so ridiculously large that it is impossible to study it with current human technology, let alone master it.

But according to the famous Kardashov index, the third civilization of the universe, it can harness a trillion trillion times more energy than the first civilization, so it's perfectly capable of using Planck levels of energy. Of course, a civilization that big would be able to build a stable wormhole for time travel. It's just a conceptual understanding. The question is, are there really three civilizations in the universe?

Let's start with a science fiction novel. There was a novel published in the 1930s called The Star Maker by a man named Stappleton. The name may not be familiar to many people, but Asimov, who invented the Three Principles of robotics, may be familiar to sci-fi fans. Asimov borrowed many of the concepts from The Star Maker, so this novel The Star Maker can be said to be the originator of modern science fiction, which has put forward countless concepts that have shocked scientists.

The hero of The Star Maker has a daydream in which he travels through different galaxies in the universe, experiencing the rise and fall of different cosmic empires. He found that higher civilizations tend to be low profile, hiding their presence and not allowing their high-tech to contaminate lower civilizations. When he meets The Star Maker himself, the man of our mythology, he discovers that the universe we live in is just one of many universes, each with different physical laws.

In his travels he encountered such a complex civilization. What is it capable of? They were able to enclose their sun in a giant sphere, thus directly harnessing all the energy produced by the sun. This concept struck Dyson as a physicist, and he took it and developed a theory of his own.

Dyson believes that with the development of human civilization, the demand for energy will continue to upgrade, when humans rise to Carl to win the second-level civilization, you need to total the direct use of solar energy output, then humans will create a ball, the sun completely encase, direct acquisition of energy inside, it is called "dyson sphere.

If such a Dyson sphere exists, it's easy to find, because it emits a kind of infrared radiation. In other words, if the Dyson sphere is found, it is equivalent to finding the second level or higher civilization in the universe. Then scientists who are keen on searching for extraterrestrial advanced civilization will be excited and have a sense of purpose in life. They should point their telescopes to the space to find the Dyson sphere.

Fast forward to 2015, and scientists have discovered a strange star 1,400 light years from Earth. The star, named Tabi, is 1.43 times the size of our sun. Where was his wonder? It was the light that astronomers observed suddenly dimmed by 22% in 2013. That's an incredible statistic, because even a planet the size of Jupiter passing in front of the sun would only reduce its sunlight by 1 percent, and it would lose 22 percent. So what could have caused the star to dim so much?

Some people's first reaction is that your equipment is malfunctioning, something is wrong, or the dust that has accumulated on the surface of the telescope is too thick to see. You can't say it doesn't make sense, because troubleshooting the equipment itself is always the first step. Scientists quickly rejected this simplistic explanation after crunching the numbers. Because this dimming has been repeated several times over the years.

In 2011, for example, it dimmed by 15%, and then astronomers predicted it would dim again in 2017, and it did, by 3% that year. Scientists began to run wild, offering several explanations. One was that there was a giant planet in the middle of the solar system. How big was it? It has to be 12 times bigger than Jupiter, and it orbits the sun, blocking it in front of the telescope every once in a while, causing it to darken periodically.

But when we looked at the data, we immediately dismissed this hypothesis, because it was dimming by anywhere from 3% to 22%. Could the giant planet be shrinking its bones? Can you keep getting bigger and smaller? The second hypothesis, that a planet had fallen into Tabi, causing it to temporarily dim, was dismissed as soon as it was suggested that the dimming of Tabi was a periodic event, not a one-off event, so it was ruled out.

A third possibility is that dust from the star's disk is blocking Tabi's light. In the early days of star formation, gas and dust form a huge disk around the star, much larger than the star itself, so when the disk passes in front of the star, it can block its light. This IDEA SEEMS plausible, BUT WHEN astronomers TOOK a CLOSER LOOK AT Tabi'S OTHER PARAMETERS, THEY FOUND THAT IT WAS A mature STAR, NOT a mean ONE, SO THE DUSTY DISK THEORY was ruled out.

One remaining interpretation is that Tabi is surrounded by a massive facility built by an alien civilization, such as a Dyson sphere. Such an alien civilization could cause Tabi's planet to darken periodically as it uses astral energy. Of course, scientists are still searching for other explanations, and the idea of extraterrestrial civilization is not immediately accepted by the mainstream. Until other explanations are exhausted, more scientists will be confronted with the option of extraterrestrial civilization. So the jury is still out on whether Tabi's periodic dimming is natural or intelligent.

The idea that a Dyson sphere could wrap around an entire star sounds pretty fanciful to us today, but it's been around since the 1960s, and for decades, scientists have been scanning the sky for signs of infrared radiation produced by a second-order cosmic civilization. Scientists at Fermi Lab, outside Chicago, scanned as many as 250,000 stars for Dyson spheres, found only four possible objects, and are still unable to determine whether Dyson spheres exist. The James Webb Space Telescope, launched in 2018 to look for infrared radiation, has yet to find any trace of Dyson spheres. So the existence of civilizations beyond the second level of the universe remains a mystery.

But Dyson himself wasn't surprised that he couldn't find a Dyson ball, because his understanding is that with our current technology, looking for advanced civilizations in the universe is like being in a dark room. Black cats are also extremely difficult to find. He thinks if there are aliens out there, they're likely to behave in ways we wouldn't expect. Signs of teleportation from extraterrestrial Ufos suggest they may have acquired the ability to build wormholes and use them for time travel. The technology is no longer so far ahead of us, but beyond our wildest dreams.

Time travel through wormholes has long been a human dream, of course, and it now seems like an impossibly long road with no end in sight. But the dream has a distance, but this distance is a grand road, or a dead end, really hard to say.
