Exclusive: Grave doubts over LIGO’s discovery of gravitational waves

The news we had finally found ripples in space-time reverberated around the world in 2015. Now it seems they might have been an illusion.

THERE was never much doubt that we would observe gravitational waves sooner or later. This rhythmic squeezing and stretching of space and time is a natural consequence of one of science’s most well-established theories, Einstein’s general relativity. So when we built a machine capable of observing the waves, it seemed that it would be only a matter of time before a detection.

Do you like blowing bubbles?

So does our Milky Way galaxy—although these bubbles might be a little bigger than what you’re used to. Two bubbles, each 25,000 light-years tall, are extending above and below the disk of the galaxy like the two halves of an hourglass. Discover possible explanations for these bubbles:
