A study published on March 3, 2025, in the Journal of Physics: Condensed Matter, reveals that room-temperature superconductivity is theoretically possible, reigniting hopes for a technological revolution. Researchers from Queen Mary University of London and the University of Cambridge found that fundamental constants, such as electron mass, electron charge, and the Planck constant, determine the upper limit of superconducting temperatures.
Superconductors, materials that conduct electricity without resistance, could transform energy transmission, medical imaging, and quantum computing. The research indicates that the theoretical upper limit for superconducting temperatures falls within a range of hundreds to a thousand Kelvin, potentially including room temperature.
Professor Pickard of University of Cambridge, co-author of this study, stated, "This discovery tells us that room-temperature superconductivity is not ruled out by fundamental constants...It gives hope to scientists: the dream is still alive." The findings suggest that our Universe's constants allow for conditions where this breakthrough might be achievable, encouraging further exploration and experimentation in the field.
