What rules actually prohibit us from building a warp drive?

In 1994, Miguel Alcubierre was able to construct a valid solution to the equations of general relativity that enable a warp drive. But now we need to tackle the rest of relativity: How do we arrange matter and energy to make ...

AI reshapes how we observe the stars

AI tools are transforming how we observe the world around us—and even the stars beyond. Recently, an international team proved that deep learning techniques and large language models can help astronomers classify stars ...
