After 10 years of black hole science, Stephen Hawking is proven right
Researchers have spent 10 years improving the massive detectors they use to catch shockwaves from colliding black holes, and now the science is precise enough to test one of Stephen Hawking's key ideas.

Now, in the journal Physical Review Letters, researchers say their ability to analyze gravitational waves has improved so much over the past decade that they were recently able to verify a key idea about the growth of black holes — one put forth by Stephen Hawking back in 1971. The current LIGO observatory, which is funded by the National Science Foundation, is facing potential budget cuts, with the Trump administration proposing steep reductions in 2026.
