Re: A Breakthrough in High-Pressure Physics
#2For 80 years, scientists have been trying to figure out how to produce metallic hydrogen. The search is finally over, and this breakthrough is going to transform everything from space travel to how we turn lights on and off.

Any timeframe for production?

#4Apparently, this was pre-published in October. Previous discussion here[0], ArXiv link here[1]. The news today is the peer-reviewed version in Science of the same paper, as I understand it.

Scientists first need to see if it's stable at room temp, and that should take a few months. After that, it'll be up to how quickly it can be reproduced.

Actually, this is new! This particular breakthrough has a different molecular structure than what was found back in October, and the way it's been configured is different.

Thanks. Some of the critiques I've been reading about in other news articles are saying that this is just the polished version of the same results. Interesting to hear that either the competing researchers or the news outlets reporting this are wrong.

that's interesting! can you share any of those links? curious.

#9The title for this is horrible, the thing that really needs to be emphasized is the metallic hydrogen. The other story on HN about this...

...mentions they are going to release the pressure in a few weeks. Anyone know if they have tried to measure the conductivity yet? I assume that would be one of the first things they'd want to do.

Does anyone know of other groups that are trying to replicate the results? For something as seemingly exciting as this, I would hope it would attract a lot of attention. How much specialized equipment does it take to achieve these pressures and temperatures? $1 million? $10 million?
