*"Beyond Light Speed: Unlocking the Secrets of Warp Drives, Wormholes, and Quantum Travel"**
" Travel Faster Than Light"
There are some amazing sights in the universe that can be seen with a powerful telescope. But will we ever be able t o go to those places and see those amazing sights with our own eyes?
Now scientists are making warp drives, and they are trying to find out how they can find cracks in the fabric of our universe and open the wormholes. They want to keep the entire universe within their reach, but for this, they will have to break a basic rule of physics. Can we travel faster than light? Can we travel faster than space? Space, time, and life itself. We will find out the secrets of the universe through.
Humans have always seen stars. For thousands of years, we have believed that they are as close as the moon and the sun—so close that we can reach them. But now we know how big our universe is.
The nearest star is 40,000 crore kilometers away from us. The fastest spacecraft we have today will also be able to reach there in 10,000 years. To prove the truth of the universe, we will have to do what physics calls impossible. We will have to travel faster than the beam of light.
When I was a kid in Mississippi, I used to sit by the campfire at night. I used to watch the flames of the fire for hours. I used to wonder what this light is made of. I used to think that it looks solid for a moment, but how does it disappear all of a sudden?
Sean Carroll is a theoretical physicist at the California Institute of Technology. He is also stunned to see the mysterious nature of light.
The speed of light is 2,97,600 kilometers per second or 107 crore kilometers. Nothing is faster than the speed of light. To be honest, this is the maximum speed limit of everything in the universe. Light travels 10,00,000 times faster than sound. It is so fast that it can go around the earth in just one second. But the mystery of light is much deeper than its breathtaking speed.
The way it moves, nothing else in the universe moves in the same way. Let's say for a moment that I'm a very dirty person, and I'm spreading dirt on the road. I'm going to include the speed of my car, which is 50 kilometers per hour.
Now, if I throw my slurpee in the same direction at a speed of 30 kilometers per hour, it's a simple calculation. The slurpee will go ahead at a speed of 80 kilometers per hour. If I go back at a speed of 50 kilometers per hour and throw the slurpee at a speed of 30 kilometers per hour, someone standing on the road will think that the slurpee is going back at a speed of 15 kilometers per hour. The speed of Sean's car changes the velocity of his drink. But the rules that apply to light don't apply to cold drinks.
When I release a beam of light from a car, its total velocity is always the speed of light. Light will seem to move at the same speed. No matter what the speed of my car is, we can't connect the speed of light to the speed of the car. The speed of light will always be the speed of light.

Because of these unique rules of moving ahead of light, Albert Einstein had to rewrite the basic rules of the universe. He felt that space and time are neither fixed nor absolute. Rather, they are connected and relative. As soon as this came to his mind, he gave the most famous equation in history: **E = mc²**.
Time and space are actually an underlying part of space-time. How do you divide space-time into time and space? It depends on your movement.
That's why when Einstein realized that time and space are one and the same, he assumed that energy and mass are one and the same. **E = mc²** means that the more energy we put into a rocket, the more its mass increases. The bigger it is, the harder it is to fly.
It's impossible to make it fly at the speed of light because then the rocket will be too big. As you get closer to the speed of light, that energy will also increase. If you want to go at the speed of light, you will need infinite energy to accelerate at that speed. But even if you get the energy, you will never be able to reach that speed.
Because of relativity, light is both our friend and our enemy. Because of its very fast speed, we can communicate almost immediately even at the two corners of the earth. But since we cannot move faster than light, we can never reach those stars in our solar system that are far away from us.
But this gentleman believes that he can get us out of this cosmic jail. He believes that he has found a way to break the rules of Einstein so that we can reach the stars. Miguel L. Cubiere is a physicist from Mexico City, and he has made a warp drive.
"My warp drive is a way to go from one place to another, but it's completely different. We usually go into space by walking or flying, but this is a way in which we don't have to do anything. Space will move inside it."

Miguel came up with the idea from another aspect of Einstein's theory of relativity—that the shape of space can be distorted by mass or energy.
Its basic idea is that we can spread space all around us. We can go far away from the things behind us and secure the space in front of us and get closer to the things that are in front of us. But in the meantime, we will not move from our place.
Suppose there is a spaceship. We have to fly in space for it, but we can't fly faster than the speed of light in it. But we secure space from here and spread it from here.
Now you can see that it has come close to it, but it has gone quite far from the edge. But this spaceship is not even moving from its place compared to the things around it.
The biggest advantage of Miguel's idea is that the spaceship is actually standing inside the bubble of space-time. Because it is not moving, its mass is also not increasing.
We can go at any speed in this because no rule of physics says how fast we can warp space, how fast we can secure or spread space. We can do this at any speed.
This warp drive of Miguel is the unique spread of Einstein's cosmic speed limit theory. But it is still just one, and a very important thing is missing in it.
It is an exotic substance, which is called negative energy—the thing that many scientists do not believe in its existence. But one person has complete faith in negative energy. He believes that he has made it in his lab as well. Warp drive—this may seem like science fiction, but after surfing a warping bubble in space, Einstein also thinks it is right.
But there is a flaw in it. A warp drive can only work with a mysterious power source: negative energy. Today, most of the scientists believe that this is just a theoretical concept, which has not been proven.
But Yale University's atomic physicist, Steve Lamoureux, believes that he will find the exotic form of energy. According to him, the answer is hidden in the fabric of space. We usually believe that the vacuum of space is completely empty.
Says that the vacuum of space is constantly shining with the energy of microscopic pulses because the particles in it keep forming and disappearing. To create negative energy, we need to think of a way to suppress this constant chatter.
Steve thought that the best way to do this is to change the shape of space. Let me give you an example. Let's say that two ships are sailing in a stormy sea. The waves hit one ship and return, and the same happens with the other ship. In this case, the wave density between the two is less, whereas in the sea, it is more when there is one ship. If we put two ships in a stormy sea, they will pull towards each other.
Steve's theory is that if we reduce the vacuum of space like the space between two ships, then some of the shining zero-point energy will not be able to enter it. Then the energy outside the vacuum of space will increase, and it will force it to shrink. That force will be the identity of a negative energy.
Steve decided to make it in his lab. It took him more than 10 years to give his idea its true form. We call this experiment a time machine, but it is actually a time machine 2. This is the second version of our experiment. I named it this way because it took me 15 years to come up with this measurement. To be honest, it should be called a time-wasting machine. Inside this vacuum chamber, there are two small metal plates which are as wide as a person's hair and are apart from each other.
After placing them so close, it was very difficult to keep them apart because they had to be placed at an atomic level. The zero-point fluctuation of the empty space will not be able to come in between the two plates. So when we bring the two plates close together, there will be very less fluctuation compared to the outside of the plates. This increases the force, and the closer it gets to the plates, the stronger it becomes. And this is made up of negative energy.
The zero-point energy fluctuation is much higher than the fluctuation that occurs in between them. The pressure from the outside pushes them inwards. Or we can also say that the negative energy spreads the space around it.
Steve, after so many years of hard work, has become the first person in the world who has measured the force generated by negative energy. But the amount he has got is very little. That force was equal to the weight of a red blood cell in the gravitational field of the Earth. It was very small.
If we take thousands of such plates which we used in our experiments, then we can get a very large force. This discovery of Steve's may be a small step towards warp drive. But it has been proven that Miguel Alcubierre's warp drive theory does not break the laws of physics.
A warp is an energy that drives the warp drive and is necessary for space. He also opened the way for another thing. A wormhole. A hole in the fabric of space.
If a theoretical object is real, then it is possible that we can go inside that hole and then go out beyond the universe. But are wormholes really outside the science fiction fantasy? If they are, then how will we know where they will take us?
Now a physicist has shown the courage to go into these unique portals that want to make a way through a wormhole. We have heard about wormholes. These are cosmic shortcuts that bring alien worlds to our doorstep. But how can we make them? How can we use them?
To travel through a wormhole, we need exotic technology and also the courage to enter an unknown area. We have a network of corridors all over the Earth. We often come and go through strong tunnels. We are going inside a strong tunnel, and it looks like it is made of concrete and reinforced steel. This is a very safe way. I can cross it with my car, and I will know what is happening.
Physicist Stephen Hsu is fascinated by the concept of stability and instability. Whether it is the stock market, real estate values, or space-time wormholes. When we look at a particular system, we see a fundamental property that determines whether the system is stable or not. A simple example is this pen, which is balanced like this. If it is balanced correctly, there is no problem. But if there is a slight jerk, it goes into a completely different state.
Then we thought, can we make a wormhole that has such properties that we can estimate its behavior and it is completely stable? These are the two qualities that should be in a wormhole.
Einstein's Theory of Relativity was also the beginning, which shows how we can easily turn space like a flexible sheet. Take a sheet of paper and assume that you are like this ant floating on it. If you have to go from here to here, then you have to go from here to here. But if this paper is turned, then it will have to walk on it like this.
But if we assume that a tube is also attached to it, then this ant can easily come from here to here through it. In science fiction, wormholes are the ways through which a starship can pass. But it does not shine on the real architecture of a wormhole.
Now, in this two-dimensional example, we can see that the mouth of this straw is only round. But because we live in a three-dimensional world, the mouth of a wormhole may be like the interior of a bubble. If a real wormhole is somewhere in space, then its mouth may also be like this.
But Stephen is thinking whether we can make a copy of it. A cosmic engineer will first make two mouths, then join them together. Then he will pull one mouth many light years away. But the tunnel between those two mouths will not be part of our space, and it will be very small.
This work is very easy, but to be able to control the negative energy of a wormhole will be very difficult. It is very difficult to stabilize a wormhole. We know all wormholes because of their relativity, and they need special negative energy, exotic matter.
Now the question is whether that matter itself is stable. Stephen also calculated how this negative energy will react with the normal matter outside a wormhole to find out whether they can remain stable or not. We mathematically proved that they will be unstable.
This will be a very dangerous device because if it gets a little shock, the whole device will break. If I put it in an unstable wormhole, it will be like putting your finger in a bubble. It will burst.
To keep a wormhole open, the negative energy needed is very unstable. A man-made wormhole will break when someone tries to enter it. But there is another way. We should not use our cosmic shortcuts, but find those microscopic shortcuts that are hidden somewhere around us.
Just as there are microscopic pulses of energy in empty space, some theorists believe that there will be such microscopic holes. It is possible that there are some quantum wormholes, or there are some small fluctuations at some distance where space-time connects to each other.
Microscopic quantum wormholes are actually quantum fluctuations in space that are sometimes visible, sometimes not, and then visible again. Because we do not want to make their portals, Stephen thinks that there will be no danger in going inside them. But be careful before going inside them because there is a danger.
Quantum mechanical things are very fuzzy. They are very random and unpredictable. So if we go inside a quantum wormhole, we may be shocked and may not even know where we are. We would never want to go into a tunnel that would take us to the Pacific Ocean or to the top of mountain. There is no fixed time for quantum wormholes to come, and the destination is also unknown. We can reach anywhere at any time. Here’s your cleaned-up text without the bracketed numbers: Going inside a wormhole at a speed faster than light can be very dangerous.
We have to be prepared to face dangers. But there can be for a careful traveler. Just think, what if you reach from here to there without walking? By the way, the first journey to reach the stars is still far away.
It will take us at least 100 years to become experts in wormholes. We can turn our body into information, and we can send that information from one place to another at the speed of light. Chris Munro and Steve Ohm are quantum physicists at the University of Maryland. They are the pioneers of teleportation.
Their job is to connect at two different locations in the universe that have no common connection. We are going to do a simple experiment with these standard coins to show you that there is randomness between two coins. Let's start. Heads. Tails. Tails. You can see that we get random results between these two regular coins. If Chris and Steve manage to drop two coins at the same time, it means that they have succeeded in teleporting information on the coins. Whether it's heads or tails, or this or that, they can use a unique quantum entanglement that can create a link between the two coins.
When a bomb explodes and two sharp nails come out of it, they go somewhere unaffected by each other. Now, let's say that the bomb is an atomic world, and two sharp nails come out of it. But here, due to quantum entanglement, one piece goes to the same place as the other.
If one piece is rotating clockwise, then we can try to rotate the other piece counterclockwise. If Steve and Chris' coins are entangled, then when Steve tosses heads, Chris tosses tails. If Steve tosses tails, Chris tosses heads.
So, even though the coin is falling from one side and it's completely random, there is a correlation between them, and that is the defining feature of entanglements. These atoms are levitating like a levitated train. This is a vacuum chamber, so nothing can touch them.
They are completely isolated. Nothing can be better than this. Steve and Chris used microwave radiation to write quantum information called qubits on the first atom.
These qubits became the heads or tails of the atoms.
Then we excited both the atoms with a fast pulse of light, and by doing this, it is possible for the photon to be entangled with the internal state of the atom. Here, photons have become messengers, transmitting the information of atoms to the entire lab.
Steve and Chris are aiming the photons of each atom at the same target. When they meet, they become entangled and then entangle the two atoms. This is called quantum teleportation because that information did not go anywhere. There was no physical interaction between them.
This was the wonder of entanglement that we were able to do this.
Einstein has described it very well. He called entanglement a scary phenomenon. Steve and Chris successfully transmitted information from one atom to another.
It can also be said that they had teleported the atom. For the first time, someone had beamed matter into space at the speed of light. Now they are working on a more complex matter.
It is a good thing that this method works on more complex matter than just one atom. For example, a few hundred atoms. We can call a few hundred atoms progress.
But the question is whether we will be able to teleport 7.5 lakh crore atoms from one place to another at the same time. Will your or my copy be able to make it? It is a very difficult task.
So we have a cherry pie, and this pie is in its particular state. The atoms in this pie are mostly of carbons and organic molecules, but they are connected in such a way that we call it a cherry pie. It looks very beautiful.
Chris will be able to teleport all the atoms only when he gets information about each atom, and then the mess will spread.
Every atom present here is a representative of that cherry pie, but now it does not look like a cherry pie. The reason is that the atoms are not properly arranged. There are millions and millions of atoms in this plate.
Now you can guess how those millions and millions of atoms were arranged. That number must be so large that to write it, our entire universe will be small. Right now, we may not be able to teleport any human, but Steve and Chris believe that if this is possible, then the big reason for it will be quantum entanglement.
Quantum mechanics has been repeatedly verified in labs—in our labs and in other labs—for decades. We have been proving that quantum mechanics is an accurate description of nature. If we want to do quantum mechanical teleportation, then we have to include quantum mechanics. I would say that if there is any theory other than quantum mechanics to teleport objects, then we don't know about it.
If Einstein is right, then the speed of light will change. The universe we live in has a speed limit of approximately 107 crore kilometers per hour. This was said by Albert Einstein.
But what if Einstein is wrong? John Webb has thought of something else. He wants to rewrite the laws of the universe, and he is starting with barcodes.
