For nearly 100 years, scientists have dreamed of turning the lightest of all the elements, hydrogen, into a metal.

Now, in a stunning act of modern-day alchemy, scientists at Harvard University have finally succeeded in creating a tiny amount of what is the rarest, and possibly most valuable, material on the planet, they reported in the journal Science.

For metallic hydrogen could theoretically revolutionise technology, enabling the creation of super-fast computers, high-speed levitating trains and ultra-efficient vehicles and dramatically improving almost anything involving electricity.

Nisam skužio jesu li uspjeli napraviti da je metastabilan ili će to tek pokušati?

Tek će pokušati, za sada je stabilan samo kada je u dijamantnom škripcu


"I immediately said we have to make the measurements to confirm it, so we rearranged the lab...and that's what we did," he said. "It's a tremendous achievement, and even if it only exists in this diamond anvil cell at high pressure, it's a very fundamental and transformative discovery."

kratko je trajalo

But five different experts have told Nature's news reportrs  that they don't believe the claim and that it could be based on an  error. One scientist told the news organisation that the paper isn't  "convincing at all".

Pa vidjeti će se kada krenu smanjivati tlak. Ako i ostane u takvome stanju vrlo brzo će se moći odrediti kaj je. Ali slažem se da se trebalo pričekati i to dok ne smanje tlak. Ali kako i sami kažu htjeli su pozornost privući.
