There are many situations in which it's important to know how much force one object is applying to another item. A small, thin sticker has been designed to measure and relay such data, without ...

But because exotic compact objects would lack an event horizon, some gravitational waves could fall inward towards the object's center and then bounce back, creating gravitational echoes that leak ...

Objects would fall 30 billion times slower there than on Earth. Gravitational forces of this magnitude normally occur only in the most distant regions of galaxies to trap remote stars.
