Metaverse is a combination of “Universe,” which means the real world, and “Meta,” which means “processing, abstract,” and means a three-dimensional virtual world. As Untact culture is popular due to COVID-19, the Metaverse, which can gather a large number of unspecified people in a virtual space at once, and can perform activities without time and space restrictions, is attracting more attention. The most famous Metaverse platforms include Naver Z’s avatar service, ZEPETO, and SK Telecom’s Efriend. ZEPETO creates 3D avatars to communicate with other users and provides services that allow them to experience various virtual reality experiences. It contains AR contents, games, and SNS functions, so it is very popular among young people. In a situation where offline events are not possible due to the COVID-19 crisis, Metaverse sometimes takes the place of concert halls. In addition, the Metaverse is being used in various fields, such as workshops, events, and university welcome parties for freshmen. When you act as a new character or character that is not your usual self, you are called a “Alter ego”. Alter ego was originally used as a game term, but is now one of the most frequently used terms in Metaverse. The Millennials and Gen Z who are trying to find pleasure by creating a second ego in the virtual world away from the harsh reality is gaining great popularity. It has become the so-called ‘golden age of Alter ego’. As such, the metaverse has had many changes and influences not only on our culture but also on our daily life. Let’s take a closer look at these changes and their impacts.

As it became impossible to talk face-to-face or host events due to the COVID-19, people began to find a way to replace this situation. One such method to solve this problems is the ‘Metabus’. Metabus has the advantage of being able to gather an unspecified number of people at once in a virtual space such as the Internet, and it can be engage in activities without restrictions on time and space.

The first platform that brought the Metabus craze to Korea is ‘Zepeto’, developed by Naver Jet. Launched in 2018, the platform has gained great popularity, especially among the MZ generation in their teens and 20s. The fact that anyone can design another character within the platform and communicate with others through the character can be seen as a good target for the MZ generation, which values individuality. In particular, in combination with the recent concept of ‘boo-character’, Geppetto users find another possibility that is different from reality through their characters. This craze of ‘Zepeto’ is clearly different from other platforms in various ways, with JYP, YG, and SM actually carrying out comeback promotions for each group within the platform.

There is a platform that has become a topic of conversation as the scope of metabuses has expanded since COVID-19. It’s “Gather.town.” Launched in May 2020, Gethertown is still sensational as it allows people to hold events online that inevitably gather a lot of people in the Corona era. This advantage of Gethertown has allowed companies and government local governments as well as the private sector to host events using Gethertown. In fact, Gumi Health Center provides online counseling services using Gethertown to citizens, and large companies such as GS Retail also hold job briefings and fairs through this platform. Events using the Metabus platform continue until now when distancing has been lifted, and as the use of such metabus space increases, various companies are entering the Metabus increases. In fact, as the Metabus business expands, the stock price will rise 88 percent from the current level, and the newly inaugurated Yoon government promised to visit IT events and fully support ICT innovation projects including Metabus.

Another area where Metabus has begun to be directly introduced into real life these days is “education.” As futurist Roger James Hamilton, who predicted that 2024 would spend more time in the 3D virtual world than in the 2D Internet world, interest in the use of metabuses in education is increasing today. As you get used to non-face-to-face life due to COVID-19, you can look at various educational sites using Metabus. Yeungnam University held the entrance ceremony for freshmen in 2022 in a metabus space. At Janggi Elementary School in Siheung-si, Gyeonggi-do, Metabus is now applied to the concept of real space beyond simple space reproduction, so expectations for a metabus that creates an effective and better educational environment are increasing. Infinite space and educational materials based on Metabus can provide an educational environment beyond time and space, which is expected to be of great help to improve students’ creativity. It is expected that many institutional levels of support will be introduced in the field of compulsory elementary, middle and high school education so that the educational environment in Metabus can be actively created.

However, Metaverse, which has grown suddenly, has threats that require adequate laws and regulations. Paradoxically, the Metaverse is a free space, but without laws and regulations, it becomes a space where freedom cannot be enjoyed due to all kinds of threats. The philosopher Hobbes described the state of a society without laws and regulations as “The war of all against all.” Metaverse will also be in the state of “The war of all against all” where cybercrime and many other threats are prevalent unless suitable laws and regulations are in place. Therefore, in order to minimize expected threats and effectively utilize the Metaverse, it is necessary to correctly predict and prepare for its future. Metaverse has not yet become common enough, so appropriate laws have not been prepared, but they can gradually melt into everyday life, so we need to prepare for this. It is most urgent to prevent various cybercrimes that may occur in Metaverse. Crimes in Metaverse, such as “Avatar Sex Offences,” are already occurring, and it is difficult to punish them properly. When order is established in the Metaverse society, the advantages of it will be further highlighted and it will be utilized in more diverse fields.

This cluster of planets is less than 40 light-years away in the constellation Aquarius, according to NASA and the Belgian-led research team who announced the discovery Wednesday.

The planets circle tightly around a dim dwarf star called Trappist-1, barely the size of Jupiter. Three are in the so-called habitable zone, the area around a star where water and, possibly life, might exist. The others are right on the doorstep.

Scientists said they need to study the atmospheres before determining whether these rocky, terrestrial planets could support some sort of life. But it already shows just how many Earth-size planets could be out there, especially in a star’s sweet spot, ripe for extraterrestrial life. The more planets like this, the greater the potential of finding one that’s truly habitable. Until now, only two or three Earth-size planets had been spotted around a star.

“We’ve made a crucial step toward finding if there is life out there,” said the University of Cambridge’s Amaury Triaud, one of the researchers.

The potential for more Earth-size planets in our Milky Way galaxy is mind-boggling. The history of planet-searching shows “when there’s one, there’s more,” said Massachusetts Institute of Technology astrophysicist Sara Seager.

“With this amazing system, we know that there must be many more potentially life-bearing worlds out there just waiting to be found,” she said.

NASA’s Thomas Zurbuchen, associate administrator for the science mission, said the discovery “gives us a hint that finding a second Earth is not just a matter of if, but when,” and addresses the age-old question of “Are we alone out there?”

“We’re making a step forward with this, a leap forward in fact, toward answering that question,” Zurbuchen said at a news conference.

Last spring, the University of Liege’s Michael Gillon and his team reported finding three planets around Trappist-1. Now the count is up to seven, and Gillon said there could be more. Their latest findings appear in the journal Nature.

This crowded yet compact solar system 235 trillion miles away is reminiscent of Jupiter and its Galilean moons, according to the researchers.

Picture this: If Trappist-1 were our sun, all seven planets would be inside Mercury’s orbit. Mercury is the innermost planet of our own solar system.

The ultracool star at the heart of this system would shine 200 times dimmer than our sun, a perpetual twilight as we know it. And the star would glow red, maybe salmon-colored, the researchers speculate.

“The spectacle would be beautiful because every now and then, you would see another planet, maybe about as big as twice the moon in the sky, depending on which planet you’re on and which planet you look at,” Triaud said Tuesday in a teleconference with reporters.

Years are exceedingly short in this star system the planets take just 1 to 20 days to orbit Trappist-1.

The Leiden Observatory’s Ignas Snellen, who was not involved in the study, is excited by the prospect of learning more about what he calls “the seven sisters of planet Earth.” In a companion article in Nature, he said Gillon’s team could have been lucky in nabbing so many terrestrial planets in one stellar swoop.

“But finding seven transiting Earth-sized planets in such a small sample suggests that the solar system with its four (sub-) Earth-sized planets might be nothing out of the ordinary,” Snellen wrote.

Gillon and his team used both ground and space telescopes to identify and track the planets, which they label simply by lowercase letters, “b” through “h.” As is typical in these cases, the letter “A” in upper case is reserved for the star. Planets cast shadows on their star as they pass in front of it; that’s how the scientists spotted them.

Tiny, cold stars like Trappist-1 were long shunned by exoplanet-hunters (exoplanets are those outside our solar system). But the Belgian astronomers decided to seek them out, building a telescope in Chile to observe 60 of the closest ultracool dwarf stars. Their Trappist telescope lent its name to this star.

While faint, the Trappist-1 star is close by cosmic standards, allowing astronomers to study the atmospheres of its seven temperate planets. All seven look to be solid like Earth – mostly rocky and possibly icy, too.

They all appear to be tidally locked, which means the same side continually faces the star, just like the same side of our moon always faces us. Life could still exist at these places, the researchers explained.

“Here, if life managed to thrive and releases gases similar to that that we have on Earth, then we will know,” Triaud said.

Chemical analyses should indicate life with perhaps 99 percent confidence, Gillon noted. But he added: “We will never be completely sure” without going there.
