신박한 방법으로 시간 여행은 불가능함을 입증한 천재 과학자 스티븐 호킹

Is it really possible to travel through time? According to the theory of relativity, it is possible to travel through time to the future. Here is a UFO that can fly up to 99.99% of the speed of light. Now the UFO will go on a space trip on this UFO. At this time, the closer the UFO gets to the speed of light, the slower time flows. If the UFO flies at 99.99% of the speed of light for a year, the Earth's time will be about 70.71 years. The time of the UFO on the UFO is about 70.71 times slower than the Earth's time. For the UFO, after only 5.16 days, the Earth's time is about a year. Also, according to the theory of relativity, the time in a space with strong gravity flows relatively slowly. Let's take a look at the planet of waves in the movie Interstellar. The gravity on that planet will slow our clock compared to Earth's drastically. How about that? Every hour we spend on that planet, 7 years back on Earth. Cooper and Brand went to this place for a very short time to investigate the planet of waves. Dr. Romilly, who was waiting outside, had a very long time. I've waited years. It's 23 years. 4 months, 8 days. The UFO is running very fast at a speed close to the speed of light, and the time is getting slower. Time flows slowly in a space with very strong gravity. Both are time-delayed phenomena according to Einstein's relativistic theory. In this way, time travel to the future is theoretically possible and actually possible. Because we can run at a very fast speed or go to a place with strong gravity. Then, how about time travel to the past? Many scientists are studying whether time travel to the past is possible. Among them, there are Tifler cone, black hole, wormhole, space strap, etc. Then, what do scientists think about time travel to the past? Yes, it's almost impossible. But what if this is the case? If our human beings survive for a million or ten million years, and have a very advanced technology, and have built a powerful civilization, it will be a civilization that dominates our galaxy and eats the galaxy. If it's that civilization, wouldn't it have somehow revealed the way to time travel to the past? They make a drorian that goes to the past, and send a terminator to the past. But if time travel was really possible, why haven't we ever seen a time traveler from the future? There have been no witnesses who have seen a time traveler so far, and there are no historical records at all. All the people who claimed to be a time traveler or met a time traveler have been proven to be swindlers so far. Is time travel possible in the past? Genius physicist Stephen Hawking prepared an interesting experiment to prove that time travel is impossible in the past. I will hold a party for time travelers. Stephen Hawking also made an invitation to a time traveler party. It was written like this in this invitation. Invite a party for time travelers. This party is hosted by Professor Stephen Hawking. There was also a place where the party was held in this invitation. In case the party venue, Cambridge University, doesn't exist in the future, it was very kindly marked with the latitude and longitude. And the exact date and time are also written. The coordinates of the time and space are very clear. The party will be held at 12 p.m. on June 28, 2009. Dr. Stephen Hawking prepared cool drinks and delicious food with Discovery Channel and waited for the time traveler. Discovery Channel recorded all this process. It's almost 12 o'clock now. June 28, 2009, 12 p.m. at Cambridge University. No one came to the party hosted by Dr. Stephen Hawking for time travelers. What the hell is going on? Even if you're not a time traveler, even ordinary people, no one comes. Here's the truth. I didn't even reveal the party venue, time, and invitation until the party day. This is all my plan. No, the party date and venue. You didn't even reveal the invitation? Then, of course, no one can come. It's a little ridiculous. But Dr. Hawking explained it like this. The reason I revealed the date, time, and venue after the party is to prove to you that time travel is impossible in the past. If time travel was possible in the very distant future, time travelers who checked the invitation would have attended the party on a time machine. But no one came to the party for time travelers. Time travel to the past in the future proves impossible. In the end, the party hosted by Stephen Hawking for time travelers ended without anyone coming. Now, Stephen Hawking proved that a time machine that goes to the past in the future in a very playful way has not been developed. Then why didn't time travelers come to the past? Stephen Hawking explained that time travel is impossible in the past with the hypothesis of time order protection. What is the hypothesis of time order protection? Here is the subway station that appeared briefly in the movie Matrix 3. The main character, Neo, runs to the left end to escape from here. Surprisingly, Neo appears on the right again. Let me introduce you to the space of Missna, a concept similar to the subway station in the movie. Here is the owl's bedroom. This owl's bedroom is the whole universe. Now the owl will go to the left end of the room as Neo did in the Matrix. In reality, the owl should hit the wall. But the owl doesn't hit the wall, it comes out again from the right side of the room. And if the owl moves forward from the left end of the wall, it will come out of the right wall as much as it crossed the wall. Now, this time the owl will move to the right end. When the owl passes the right wall, it will reappear from the left wall. And if the owl moves down, it will come out again from the top, and if it goes up, it will come out again from the bottom. Now, this space is called the Missna universe. It is a virtual universe designed by Charles Missner, an American physicist. But Stephen Hawking, who studied the Missna universe, came to this conclusion. The Missna universe is mathematically almost the same as the wormhole. The Missna universe can be described as a wormhole with the same entrance on both sides. Stephen Hawking has been studying the Missna universe. But he found one strange thing. Now, let's say there is the Missna universe and the owl. The owl will shoot light to the right with the flashlight. At this time, the light will pass through the right and come out again to the left. But if this process is repeated infinitely, the light will continue to increase, and eventually the Missna universe will be filled with infinite energy. And as this energy creates a very powerful gravity field, the Missna universe will eventually collapse. This phenomenon is the same in the wormhole. The light passes through the A entrance of the wormhole and comes out through the B entrance, and the light passes through the A entrance again and comes out through the B entrance. If this is repeated infinitely, the inside of the wormhole will be filled with very powerful energy and eventually collapse. Now, this is similar to the mistake that a live broadcaster sometimes makes. A streamer was broadcasting live, but he accidentally turned on the speaker and broadcasted. The sound of the broadcast goes back into the microphone through the speaker, and the sound of the microphone is output again through the speaker, and it goes back into the microphone again. If this is repeated infinitely, the broadcast will be at a level that cannot be heard at all. The broadcast will be at a level that cannot be heard at all. What do you think? You can feel it, right? Both the Missna universe and the wormhole are very unstable in terms of stochastic and quantum mechanics. Even if a wormhole exists, it will be maintained for a short time in a smaller size than one atom or more. If a time traveler passes through a wormhole and tries to go to the past, the entrance of the wormhole will be closed and collapsed, so the time traveler will eventually lose his life. Dr. Stephen Hawking also argued that some unknown laws of nature are blocking time travel in the past, and that physical laws do not allow the existence of time machines. And Stephen Hawking said this funny thing. Nature prohibits time travel in the past to protect historical objects. For example, the paradox of my grandfather. To briefly explain the paradox of my grandfather, If a wormhole goes to the past and kills my grandfather, my grandfather will not be able to give birth to my father, and then my father will not be able to meet my mother, so I will not exist. Then, how could I come to the past from the future? This is the paradox of my grandfather. There's another paradox. If I go to the past in the future and kill myself in the past, how could I come to the future? This is also a paradox. There's another paradox. Now I'm a very famous writer, and I'm going to the past on a time machine, and I'm going to give myself a novel that's going to be a hit. I'm going to be a very famous writer with a novel I got from myself in the future. Now, then, is this novel written by me in the future? Or did I write it in the past? You don't know, do you? Now, this is the free paradox. All of this is a paradox created by time travel in the past. This paradox is as fatal as one. The cause is not the result, but the result makes the cause, and the front and back are messed up. Now, we've learned about Stephen Hawking's invitation to time travelers. According to Dr. Stephen Hawking, time travel seems impossible. But there are some scholars who claim that time travel in the past is possible. For example, Dr. Kipson. Time travel through Black Hole and T-flow cylinder. Also, time travel through wormhole. I've uploaded these two videos to my channel. I hope you can time travel. Please click on the link in the comments and the description column to watch these two videos. So far, it was the 26th Interstellar review. I was a reviewer.
