A superconductor is a material that exhibits superconductivity under critical temperature, where electrical resistance vanishes and magnetic fields expel from the material. Tremendous energy savings by superconductor are said to have the potential to address global energy challenges and enhance computing performances in addition to other possibilities. Room-temperature superconductors under ambient pressure may take the world to a  new level.
  Numerous scientists have researched superconductors, but room-temperature superconductors remained elusive until July when the team published preprints declaring LK-99 achieved room-temperature superconductivity under ambient pressure. Although scientists’ first impression of LK-99 was negative, LK-99 grabbed attention worldwide, and various labs tried to do replication experiments and theoretical simulations. 
  Initial attempts including teams at the National Physical Laboratory of India did not find direct evidence of superconductivity. After many more replication efforts including the team in the  POSTECH Department of Physics, many specialists are confidently saying LK-99 is not a room-temperature superconductor. The Korean Society of Superconductivity’s LK-99 verification committee took a similar stance. Meanwhile, some scientists suggest that the possibilities of LK-99 utilization still exist. 
  In the case of LK-99, research that seemed like a breakthrough fell short. Sensational breakthroughs that were not thorough and had negative first impressions among experts did not always fall short, resulting in an innovative landmark. In the field of Physics, the Bohr model also had evident limitations and an indescribable basis. Many physicists doubted and criticized it in the sense of lacking. However, Bohr turned out to receive the Nobel Prize in Physics for the Bohr model. This phenomena is not only limited in the field of science. For example, in the field of arts, Astor Piazzolla’s Tango received criticism from experts as being unsophisticated music. His music teacher Nadia Boulanger advised Piazzolla to not abandon the music of his youth and culture. Tango, as a classic form, turned out to gain significant support and popularity. 
  Great discoveries that challenge existing theories might come from young or immature scientists with limited prior knowledge. Experts can lead them with an open mind, filling in the gaps, while young scientists freely share their bold ideas. From the perspective of the scientific community, it would be beneficial for such open-minded research approaches and replication to be maintained.
