Metallic Hydrogen: Superconductor Discovery and Skeptics



Hydrogen is the first element of Group 1 of the periodic table and is abundant in nature. They have one proton and one elector. Freezing at 253-degree centigrade hydrogen become liquid and is widely used in Rocket fuel. Under normal atmospheric pressure hydrogen atom pair up to form the hydrogen molecule. The metallic property of the hydrogen is displayed when it loses the electron.

First Hypothesis on Metallic Hydrogen


The scientist named Eugene Wigner and Hillard Bell Huntington, the Princeton physicist hypothesized that massive pressure on the hydrogen turns it into the metal. This was hypothesized in the year 1935 (1). Until now there has not been any successful experiment to test this hypothesis.


Metallic Hydrogen Discovery


The Post-doctorate researcher Dr. Silvera and Ranga P. Dias has published the finding of metallic hydrogen in Journal science. The published journal claims that they have made metallic hydrogen by applying 495 Gigapascals pressure at the temperature -268-degree centigrade. Squeezing hydrogen in the liquid is achieved by compressing the freezing hydrogen with the hardest substance in the world i.e. diamond.

Acceptance of research paper in the Journal science is the arduous task as it only publishes 7% of the articles received.

Application of Metallic Hydrogen


The solid metallic hydrogen is the superconductor. It can transfer the electricity without the resistance. It has several implications in various modern devices.

It is estimated that more than 15 percent of electricity is lost during the resistance. So the discovery of the superconductor can be of the great energy saver.

It has prime application in the fastest trains, Sonic computer, fastest vehicles, rocket propeller and many others.

Due to the wide application, the metallic hydrogen is often referred as the holy grill of high-pressure physic.

The metallic hydrogen is found in the core of the Jupiter. This is believed to be the hidden secret beneath the high magnetic field of the Jupiter.


Skeptics


There has been the speculation that the experiment results as it does not conform the metallic productivity and conductivity, as it has not been accessed. Further, there has not been series of experiment to confirm the result. Further, the evidence from past can put everyone in doubt. The finding of the metallic hydrogen was claimed in 2016 but was unable to replicate (2).
