There are many amazing and interesting things in deep space, and one of them is wormholes. Scientists have speculated and studied wormholes for years, but now that they claim to have finally found the first, can wormholes really exist? What is a wormhole? Why are astronomers so excited about it? Today we talked about the first wormhole scientists have discovered!
Many people may not know how much the Earth has done to protect us from extraterrestrial objects, such as the solar wind and so on, thanks to its unique features. However, once you step outside of Earth, all protections are gone, and the deeper you go into space, the scarier things you encounter, one of which is a wormhole. Wormholes are both fascinating and terrifying, and scientists have discovered many things about them and even created one like them 39bet-đua chó-game giải trí -đá gà-đá gà trực tuyến-đánh bài. But what exactly is a wormhole?
A wormhole is actually a solution to the equations that describe Einstein's theory of general relativity, which connects two distant points in space or time through a tunnel. In this case, however, the length of the tunnel is shorter than the distance between the two points, which go through a tunnel, meaning you can call a wormhole a shortcut between two points. Wormholes have been hypothetical objects for years, and they've only appeared in many science fiction movies, but this is no longer the case with recent discoveries.
I'm sure many of you have heard of something called an Einstein-Rosen bridge, which is the technical term for a wormhole. The name because the simplest wormhole solutions is by the great scientist Albert Einstein and Nathan Rose in 1935 began to study mathematical solution of the black hole, the hole by a singular or a point of infinite density, plus the area on the event horizon around its singularity, beyond the region, any object can escape.
Based on the physics of the universe, they found they could extend their solution to include black holes' polar opposites: white holes. These white holes also contain singularities. However, they behave in the opposite way to black holes. They don't allow anything to enter their event horizon, and any material inside the white hole is immediately spat out, which is where the wormhole comes from. Einstein and Rosen discovered that for every black hole in space there would be a white hole, because the two holes would exist at different points in space, and a tunnel would connect the two ends. This tunnel was called a wormhole.
According to their theory, although wormholes may exist, they may be extremely unstable. A single photon or particle of light passing through a wormhole tunnel will introduce so much energy into the system that the tunnel will burst, destroying the wormhole. So if you think a wormhole is a cozy secret passageway that you can safely walk from one corner of the universe to another, think again. And once you enter from the black hole side, you cross the event horizon and can never leave, which means you're stuck in the corresponding wormhole forever.
But scientists claim that humans have been able to create a stable wormhole, and even make it passable, initially by moving the entrance to the wormhole outside the event horizon of the black hole and stabilizing the tunnel itself so that material passing through doesn't immediately collapse. To stabilize a wormhole, scientists have found that you need something called "foreign matter," or something with a negative mass.
Recent research has found that wormholes containing foreign material can stay open and unchanged for longer periods of time, and the key is negative mass. Negative mass is an interesting concept. For example, if you place an object with a negative mass next to a positive mass, it will immediately accelerate, even without any source of energy. Note that strange matter is different from dark matter or antimatter. Beyond that, there's the matter of size. Primordial wormholes are expected to exist at the microscopic level, about 10 to 33 centimeters. However, as the universe expands, some wormholes may be stretched to even larger sizes!
So if we accidentally went into a wormhole, what would we see? Scientists think the entrance to the wormhole would be a sphere, like you're looking at the surface of a planet. If you look into the wormhole, you'll see light coming in from the other side. Wormhole tunnels can be any length, and as you wander along the tunnels, you'll see a distorted view of the region you're coming from, the universe. In addition, wormholes may be able to make a concept from the movie a reality: time travel.
When it comes to time travel, one concept we'll talk about is special relativity. Special relativity says that moving clocks run slowly. In other words, people running at close to the speed of light don't jump into their future as fast as stationary people. So if you successfully build a wormhole, initially, the two ends will synchronize in time, but if you accelerate one end close to the speed of light, that end will start to lag behind the other, and the two entrances can be combined, but one entrance will be the past of the other.
It may sound hard to understand, but if you want to go back in time, you just have to go through one end. When you leave the wormhole, maybe you will see your own past so that you can actually relive some of the moments in your life. Of course, all of this is theoretical, since we haven't observed wormholes in space yet. But a group of scientists have created their own wormhole in the lab. Can wormholes really be made? Or is that really a wormhole?
The researchers, from the Autonomous University of Barcelona in Spain, have designed a spherical device capable of diverting magnetic fields away from the wormhole. They said they were inspired by the theoretical work of Alan Greenleaf, a mathematics professor at the University of Rochester in New York. At the time, Greenleaf proposed a theory of electromagnetic wormholes, which could transmit electromagnetic waves through an invisible tunnel between two points in space. However, there are several reasons why Greenleaf's theory could not be tested, but the Spanish team was able to use magnetic metamaterials and metasurface to design a wormhole that would transfer magnetic fields from one point in space to another via a path undetectable by magnetism.
While that sounds possible in theory, it's quite difficult in practice! After they finished their design, it took the team four months to build the wormhole. Overall effect is that the magnetic field seems to spread from one point to another point, through the traditional three-dimensional space outside a dimension, namely the wormhole experiment is a sphere composed of different layers, one on the surface of the ferromagnetic outer layer, a second lining made of superconducting materials, as well as a of ferromagnetic rolled into a cylinder and the cylinder from one end of the ball through the other end of the sphere. The sphere is made magnetically undetectable, so that the magnetic field cannot be seen from the outside.
It is important to note here that magnetic wormholes are merely an analogy for gravity, as they alter the topology of space, as if the inner region has been magnetically erased from space. At the same time, these researchers have in the past made a magnetic fiber, a device that can transmit a magnetic field from one end to the other. However, such fibers can be magnetically detected, but the wormhole they've created is a three-dimensional device that can't be detected by any magnetic field -- in other words, it doesn't really act like a wormhole. Interestingly, one practical application of the device built by the Spanish team of scientists is to use the magnetic field in a wide range of medical applications, which may be self-defeating.
Scientists are still trying to uncover the truth about wormholes, but the question is, how do they prove they exist? Russian astronomers have suggested that wormholes may exist at the centers of some very bright galaxies, and have come up with observations to prove them. But still no results, so do you think wormholes really exist?
