Scientists have long been striving to achieve room-temperature, room-pressure superconductivity, and it seems they may have made a breakthrough. If this new superconducting material proves to be successful, it could have far-reaching implications for how we generate and utilize electricity. However, before we can fully embrace this potential revolution, further scientific scrutiny is necessary.

Superconductivity is a phenomenon where electricity can flow through a material with zero resistance, resulting in zero energy loss as heat. However, achieving superconductivity thus far has required extreme pressures and low temperatures.

Researchers, led by Ranga Dias at the University of Rochester in New York, claim to have created a superconducting material using hydrogen, nitrogen, and lutetium. They achieved superconductivity at a temperature of just 21°C (69°F) and a pressure of 1 gigapascal, which is nearly 10,000 times the atmospheric pressure on Earth’s surface but still lower than the pressures required by previous superconducting materials. Dias likens the difference between their experiment and previous ones to a horse encountering a Ferrari on the road – a significant leap forward.

To create the material, the researchers compressed a combination of the three elements using a diamond anvil, a device that applies extreme pressure between two diamonds. As the material underwent compression, its color changed from blue to red, earning it the nickname “red matter.”

The research team conducted a series of tests to examine the red matter’s electrical resistance, heat capacity, and response to a magnetic field. According to their findings, all the tests indicated that the material is indeed superconducting.

However, not all experts in the field are convinced. James Hamlin from the University of Florida, for instance, expresses reservations about the research. Some of these reservations stem from a previous controversial paper published by Dias and his team in 2020, which claimed room-temperature superconductivity but was later retracted by the scientific journal Nature. Questions arose about the accuracy of the data and the derivation of the published results from the raw measurements.

Jorge Hirsch from the University of California San Diego shares this skepticism, stating that answers to these questions are needed before trusting the authors’ new data and their representation of the actual physical properties of the samples.

One challenge in gaining broader acceptance of red matter as a superconductor is the lack of understanding regarding the mechanism underlying its possible superconductivity. Dias explains that more research is needed to determine the exact structure of the material, which is crucial for understanding its superconducting properties. The hope is that a better understanding of the material’s structure, achieved through larger-scale production, will help theorists explain how and why it becomes superconducting.

If independent research groups can verify the superconductivity of red matter and unravel its structure, it could lead to one of the most significant scientific discoveries to date. Room-temperature, room-pressure superconductivity can revolutionize the electrical power grid, enhance magnetic levitation, and unlock numerous technologies yet to be imagined. However, researchers remain cautious, recognizing that rigorous scrutiny is necessary. Unlike previous experiments, the lower pressures required by red matter make it accessible to a wider range of laboratories, ensuring that other groups can replicate and validate the findings.

Tim Strobel from the Carnegie Institution for Science in Washington DC emphasizes the importance of reproducibility. While the previous work by Dias and his team has not been independently replicated, the lower pressure requirements of their latest endeavor make it highly feasible. Strobel assures that replication efforts will begin immediately, and if successful, it could mark the beginning of an energy revolution.
