magical stuff or "complete garbage"

I do not presume to claim an understanding of what is being discussed, but I am willing to admit a puckish smirk when the decorous veil of academia slips and one hand-maiden chastises another in plain-ish English:

Other scientists working in the same and related fields have told the BBC that the team's paper is short on the kind of data needed to make a proper assessment of its achievements.
"Complete garbage," is how Eugene Gregoryanz from Edinburgh University described the research. "Like everybody else who works with hydrogen at high pressures, I am appalled by what is being published in Science."
That there is so much scepticism is natural. If what is being claimed pans out, it would represent one of the major physics breakthroughs of recent decades.

The "complete garbage," if that's that it is, relates to

Scientists in the US say they have at last managed to turn hydrogen into a state where it behaves like a metal.

If that is true - and it is a controversial claim - it fulfils a more than 80-year quest to produce what many have said would be a wonder material.
Theory suggests metallic hydrogen could be used to make zero-resistance electrical wiring and super-powerful rocket fuel, among many applications.
Ranga Dias and Isaac Silvera are the Harvard researchers behind the work.
They report their experiments in this week’s Science Magazine.

Somewhere is the lost recesses of my mind, I seem to recall that the possibility and implications of what is asserted here would be akin to turning lead into gold.
