A recent preprint claims that we may someday be able to create gravitational waves in a lab. Through the use of “twisted” light, we could create powerful, high-frequency waves in a controlled setting.

This black hole really knows how to kick back. Scientists recently observed two black holes that united into one, and in the process got a “kick” that flung the newly formed black hole away at high ...

The speed of light is a fundamental constant, approximately 299,792,458 meters per second. It's the same for all observers and hasn't changed measurably over billions of years. Nothing can travel ...
