حسگر جدید از نور کند شده برای تشخیص کشش گرانشی اجسام کوچک استفاده می کند

New sensor uses slowed light to detect gravitational pull of tiny objects

Gravity, the attraction between objects with mass, is the weakest of the four fundamental forces governing physical processes. Detecting the tiny gravitational pull of objects that are just a few millimeters in size and have a very small mass is extremely challenging.
