Astrophysicists report solid evidence for a background hum of gravitational waves

Astrophysicists have found the best evidence yet for a low-frequency 鈥渉um鈥 of gravitational waves rippling through the cosmos, based on 15 years鈥 worth of ultra-precise measurements checking the timing of radio pulses from distant stars.

The evidence, newly published in the Astrophysical Journal Letters, comes from several teams of researchers, including several from the 糖心vlog视频.
