The ability to come true of things that are only in movies

Scientists have demonstrated that projects such as invisibility cloaks, artificial intelligence, instant movement . can be "released" in the future.

We all know that science fiction is in the category of . 'fiction', which means that it will take a long time to become a reality. But maybe in the future, time travel or teleportation will become a trendy trend, or cyborgs and robots with artificial intelligence together. in?

Scientists think it is possible. Let's analyze the rationality of the most popular science fiction ideas today through the following article.

1. Invisibility cloak

The Star Trek film offers the idea of ​​a film around the ship preventing the enemy from discovering. And Harry Potter adds another idea: 'invisibility cloak'.

Science has proven that creating a membrane for ships and planes is possible. But invisibility cloaks like Harry Potter are different. According to David Smith, a professor of electrical and computer engineering at Duke University, it is a kind of too perfect and unreasonable stealth. However, the research on invisible objects has made significant progress over the years.

An experiment of "invisibility cloak" has caused a stir for a long time.

Theoretically, an object does not absorb, light reflection is considered invisible. And so far, scientists have created a partial invisibility device that can re-route certain light wavelengths, bend light rays when exposed to objects.

The shirt is designed to compensate for small variations in the shape of an object, based on a metamaterial background, operating in the microwave frequency range. However, because it only works under certain conditions, namely the microwave frequency threshold of the electromagnetic spectrum, in fact, people or things that wear clothes are still visible. But with such a big step, the possibility of one day not far away, we will have an invisibility cloak that is absolutely possible.

2. Human robots: Smart computers like people

AI research, or Artificial Intelligence, has made remarkable progress in recent years. Robots and computers have proven they are more reliable than people in some special areas, like assembly lines, or calculating extreme numbers. However, there are no robots that can do basic things like . tying shoelaces.

Shlomo Zilberstein, professor of electrical science at the University of Massachusetts, said that what AI technology has achieved so far as robot overtaking people in a limited number of fields is easy, compared to The construction of robots has been considered 'common' by 3-year-olds.

At the current pace of scientific development, many scientists believe that computers and robots with superior artificial intelligence will appear in the next few decades. However, they certainly have to ensure that, when robots get 'perceptive ' will not harm humans as in the common science fiction stories.

3. Instant teleportation like "magic door"

It will not be too much to say that 'instantaneous teleportation' is what most people on Earth want to bring into reality. Scientists have discovered that particles can interact physically and often interact with each other, regardless of the distance between them.

But the biggest problem is the atomic matching at the two ends of the transport medium. According to Sidney Perkowitz, a physicist at Emory University, Atlanta, moving a large-sized object is not possible or impossible.

The measurement process that evaluates quantum information to send information to the destination may break atoms, then recreate another version at the destination. This causes a great moral obstacle.

In addition, the human body is made up of 10 ^ 27 atoms, and about 10 ^ 45 bits of information - equivalent to trillions of billion terabytes of computer hard drive capacity. This means that human quantum information exceeds the storage capacity of any device.

Currently, "instant teleport" has actually taken a step forward when scientists have succeeded in "instantaneous teleport" within a distance of 16km.

But what they transport is not an object or a human but quantum information between two photons (elementary particles in physics). And with the huge challenges just mentioned above, the idea of ​​'teleport devices' - like creating a wormhole (a hypothetical path, connecting two different spaces - time) is still far away. great

4. Weapons destroy the planet

Many sci-fi films talk about the existence of 'weapons that destroy the planet' and beyond that destroy a star - like our Sun.

Mike Zarnstorff - deputy director of Plasma Princeton Physics Laboratory, who is also a researcher on plasma technology, says it is theoretically possible.

If it is possible to launch an energy field strong enough to make a black hole toward the Sun, that black hole will increase in size exponentially, and the Sun will be "swallowed" cleanly. The same thing will happen to every other planet in the universe. But perhaps, no one expected such scary weapons to appear.

5. The object moves faster than the speed of light

Einstein's theory of relativity asserts that nothing can reach speeds greater than the speed of light (300,000 km / s). Any object cannot move faster than the light measured in the space surrounding it, if not set the limit of the velocity of the expansion or contraction of the space itself.

But this is the loophole for physicists to cherish 'faster than light'. That's the Warp drive system, which can create a 'warp bubble ' with 'negative energy' around the spacecraft.

This bubble will narrow the space - time in front of the ship and expand space - time at the stern, making the spacecraft able to move faster than the speed of light measured at the space around the bubble.

According to Baylor University physics professor Gerald Cleaver, the object inside the bubble will stand still but actually move faster than the speed of light around the bubble.

But of course 'warp drive' is still 'fiction' , because it exists many limitations. Negative energy (a mysterious form of material that only pushes each other rather than smoking) - a prerequisite for creating warp drive - is difficult to create, almost impossible.

And even if they create a sound field strong enough, they need to locate part of the 'bubble' layer in front of the bow, but that means they need to reach the speed of light - which, according to Einstein, is not can. In addition, according to calculations, it is almost certain that the negative energy field will become unstable immediately after reaching the speed of light, due to the appearance of quantum mechanical radiation.

6. Learn by . Matrix

Those who have seen the movie 'Matrix' must be impressed and . the desire to rise when Keanu Reeves learns Kungfu, or learn to fly a plane after a few seconds of downloading data.

Some scientists have recently done research to show that learning skills can be enhanced by technology. Accordingly, based on neural feedback, scientists use the magnetic resonance imaging (MRI) function, which activates brain activity patterns in the visual cortex, as appropriate. each person's mental state, thereby improving job performance.

However, to look forward to the future when just connecting and pressing the button is to become an expert, perhaps it takes a few hundred years.
