Yup, you heard it right! And No! this is not a star trek reference
Oxford scientists in 2009 bombarded aluminium with the most powerful soft X-ray laser. They focused all this power down into a spot with a diameter less than a twentieth of the width of a human hair. At such high intensities, aluminium turned transparent.
The invisible effect lasted for only an extremely brief period of time- an estimated 40 femto-seconds. But hey! The existence of such an exotic state of matter per se, opens up new frontiers for pristine research and technology. As Albert Einstein rightly said:
The process of a scientific discovery is, in effect, a continual flight from wonder.
