Scientists have made a breakthrough in creating a digital model of the physical world, which can be used to understand and interact with objects in a more realistic way. The model, called WorldString, uses data from 3D scans or videos to learn about the properties and behaviors of objects, allowing it to predict how they will behave in different situations. This technology has the potential to be used in a wide range of applications, from robotics and autonomous vehicles to smart homes and cities, and could even enable the creation of more realistic virtual environments.
