A new material that could be used to create a real-life Harry Potter-style "invisibility cloak" has been designed by Scottish scientists.
The material, called "Metaflex" could in future provide a way of manufacturing fabrics that manipulate light.
Metamaterials have already been developed that bend and channel light to render objects invisible at longer wavelengths.
Visible light poses a greater challenge because its short wavelength means the metamaterial atoms have to be very small.
So far such small light-bending atoms have only been produced on flat, hard surfaces unsuitable for use in clothing.
The supermassive black hole is 40 million times as massive as the sun and powers a quasar that existed 700 million years after the Big Bang.
Vision Pro is here and itβs a surprisingly capable device. Apple has also loaded the headset with a ton of options and features that arenβt obvious at first glance.
Engineers expect to lose contact with the private US moon lander Odysseus on Tuesday, cutting short the mission after its sideways touchdown last week.
Imagine the fun that could be had with an invisibility cloak
do not try it on the zebra crossing :D
