Each image was processed and projected, and the 0.5 μμm wavelength was selected to detect the wave packets. Images A, B, D, F, and G are at Ls≈150°; Image C at Ls≈285°; Image E at Ls≈245°. Image G is ...

For the first time, physicists have found what they are calling “compelling evidence” for low-frequency gravitational waves, ripples in space-time usually caused by massive cosmic objects orbiting ...
