Check it out, a black hole yanking on a star.

Ryu’s supercomputer sent simulated stars of different sizes and densities towards a “monster” black hole. The virtual void tugged at the stars with a mass one million times that of the sun, pulling some completely apart while others retained mass and actually returned to their normal shape.

Augmented Reality Glasses

The glasses feature a pair of 1080p displays and two wide-angle cameras that capture natural scenes of the user's environment to determine where to overlay the pre-loaded virtual elements.

The glasses are now available in two modifications: the PC Edition connects to a desktop or laptop computer via a USB-C port and projects up to five working screens in real time. The Industrial Edition is designed to pair Motorola smartphones, this version is much more mobile.
