The 'holy grail of high pressure physics': Researchers create metallic hydrogen in superconductor breakthrough that could revolutionise technology and even take man to Mars

U.S. scientists have succeeded in squeezing hydrogen so intensely that it has turned into a metal, creating an entirely new material that might be used as a highly efficient electricity conductor at room temperatures.
The discovery, published in the journal Science, provides the first confirmation of a theory proposed in 1935 by physicists Hillard Bell Huntington and Eugene Wigner that hydrogen, normally a gas, could occur in a metallic state if exposed to extreme pressure.
Several teams have been racing to develop metallic hydrogen, which is highly prized because of its potential as a superconductor, a material that is extremely efficient at conducting electricity.

HOW TO MAKE IT 

To create it, Silvera and Dias squeezed a tiny hydrogen sample at 495 gigapascal, or more than 71.7 million pounds-per-square inch - greater than the pressure at the center of the Earth.
At those extreme pressures, solid molecular hydrogen -which consists of molecules on the lattice sites of the solid - breaks down, and the tightly bound molecules dissociate to transforms into atomic hydrogen, which is a metal.
Currently, superconductors such as those used in a magnetic resonance imaging, or MRI, machines must be cooled with liquid helium to keep them at extremely low temperatures, which is costly.
'This is the holy grail of high-pressure physics,' Harvard physicist Isaac Silvera, one of the study's authors, said in a statement. 
'It's the first-ever sample of metallic hydrogen on Earth, so when you're looking at it, you're looking at something that's never existed before.'
'One prediction that's very important is metallic hydrogen is predicted to be meta-stable,' Silvera said.
'That means if you take the pressure off, it will stay metallic, similar to the way diamonds form from graphite under intense heat and pressure, but remains a diamond when that pressure and heat is removed.'

Understanding whether the material is stable is important, Silvera said, because predictions suggest metallic hydrogen could act as a superconductor at room temperatures.
'That would be revolutionary,' he said. 'As much as 15 percent of energy is lost to dissipation during transmission, so if you could make wires from this material and use them in the electrical grid, it could change that story.'
Among the holy grails of physics, a room temperature superconductor, Dias said, could radically change our transportation system, making magnetic levitation of high-speed trains possible, as well as making electric cars more efficient and improving the performance of many electronic devices.

Because superconductors have zero resistance, superconducting coils could be used to store excess energy, which could then be used whenever it is needed. 

THE ULTIMATE ROCKET FUEL

Metallic hydrogen could also play a key role in helping humans explore the far reaches of space, as a more powerful rocket propellant.

'It takes a tremendous amount of energy to make metallic hydrogen,' Silvera explained. 

'And if you convert it back to molecular hydrogen, all that energy is released, so that would make it the most powerful rocket propellant known to man, and could revolutionize rocketry.'

The most powerful fuels in use today are characterized by a 'specific impulse' (a measure, in seconds, of how fast a propellant is fired from the back of a rocket) of 450 seconds. 

The specific impulse for metallic hydrogen, by comparison, is theorized to be 1,700 seconds.

'That would easily allow you to explore the outer planets,' Silvera said. 
'We would be able to put rockets into orbit with only one stage, versus two, and could send up larger payloads, so it could be very important.'

David Ceperley, a physics professor at the University of Illinois Urbana-Champaign who was not involved in the research, said the discovery, if confirmed, would end a decades-long quest to see how hydrogen can become a metal, adding to the understanding of the most common element in the universe.

To achieve this feat, Silvera and post-doctoral fellow Ranga Dias squeezed a tiny hydrogen sample at more than 71.7 million pounds per square inch (32.5 million kg per 6.5 square cm), greater than the pressure at the center of the Earth.

The scientists created this force using synthetic diamonds mounted opposite each other in a device known as a diamond anvil cell.

They treated the diamonds with a special process to keep them from cracking, a problem that has foiled prior experiments.
'This is just at the point when the diamonds are about to crack,' Ceperley said. 

'That is why it's taken so long. Silvera had new ways of shaping the diamonds and polishing them so they wouldn't break.'
A key question is whether the pressurized hydrogen maintains its metallic properties at room temperature, which would make it extremely useful as a superconductor.

Both Ceperley and Silvera believe this will be the case, but it still needs to be proven.

Awesome breakthrough, but we perfected anti-gravity in 1953, went to other planets after 1963, were mining Mars in 1967 and oh boy what we have now is way more than awesome, like zero point energy, magnetohydrodynamic generators and quantum hyperdimensional engines. Cool breakthrough though, very noteworthy, not very practical to produce in large quantities. Maybe in 25 years. Our congratulations to the scientists.

A lot of people have accused Trump of being a Nazi and his supporters of being fascists, but in light of this I think that it's of particular importance to address the real problem.

Number one Trump is a nationalist as is his followers.

Number two there is a very real criminal conspiracy going on in government at places like the CDC...nominally controlled by Zionist Jews and Pedophiles. At the CDC there are also Egyptian racists who are all experimenting on people's lives.

Israel itself has been discovered to be a fascist nation, Egypt is an even more overt fascist nation.
We absolutely have no business supporting this project nor having anything to do with Francis, Rockefeller or the rest of the Zionist Globalist elite sociopaths.

Now if that makes someone a fascist for being in opposition, its only in their eyes because these sickos need to be finished.

As for the problem with Zionist Jews in general, I think we can't ignore the epidemic at this point. The CDC and Hollywood are full of these freaks. Now I don't mean the jewish community.

There is however a large number of the false Synagogue evil Edomites dwelling at the top of Hollywood, which is why after the Federal Reserve is audited we will demand they are expelled.

These sociopaths and sickos have brought Islam into the schools where it has no business being in front of children. The "leftist agenda" hates the nation of Israel so much that they promote open Islamic intermarriage. The Trump administration needs to bring the entire Directors Guild of America to immediate heel.

There are Communist Chinese in charge of Hollywood and also many Zionists who are destroying things for their Globalist agenda, which is behind all this "fake news" seen on television. They need to be thrown out of there and tossed in prison.

Many actors like the Damons, Afflecks, LeBeouf etc all have their own problems but are not part of this fascist group. Then there are outright Zionists who are dangerously close to the edge like George Clooney, these people need to be locked up and see what that feels like.

The whole Globalist Zionist control system is based on Fake News and no one being the wiser. They brought in drones, huge armed paratroopers and even machines to keep people in line. It has to be fully disposed of and emptied out of the cesspool.

It's like criminals have gotten into high positions of Hollywood, both Communist Chinese as well as the Al Pacinos of the world. A number of these gangsters need to be tossed in jail and they will be because they admit to being involved in satanism. Hollywood has some of the worst crooks in the world, and in fact the regular jewish community should disown them all until the Islamist creeps are dealt with.

There is a huge number of problems with the Synagogue of Satan as they call it, and you can bet they greatly fear Trump as he despises them and won't back down from their fascist threats. People like John Goldberg or Bryan Singer will finally see some jail time for being involved in this crap.

The exodus of the Operation Paperclip was a group of zionist jews as well, a hidden history that hasn't been told.
Zionist jews were the Nazis, another atrocity as of course today they are in Armenia and most of Serbia which is dedicated to the sword of Islam.
