Albert Einstein’s general theory of relativity, proposed in 1915, revolutionized our understanding of gravity. how mass bends the fabric of space-time. While this theory has stood the test of time, physicists believe that exploring theories of quantum gravity could be the key to unraveling our universe’s deepest mysteries.

One of his interests in the search for quantum gravitational signatures is black holes colliding and merging. Black holes are incredibly dense objects that warp space-time, causing falling objects to stretch like spaghetti. When two black holes merge, they create ripples in space-time called gravitational waves, which can be detected by observatories like LIGO.

LIGO, funded by the National Science Foundation and administered by Caltech and MIT. Detects gravitational waves from merging black holes since 2015. These observations consistently confirmed Einstein’s theory of general relativity.

Now, two new papers from researchers at Caltech propose innovative ways to put general relativity to even more rigorous testing. By studying the structures of black holes and the gravitational waves they produce, scientists detect possible deviations from general relativity that could indicate the existence of quantum gravity.

The first paper jointly led by Dongjun Li and Practical Wagle presents a new equation to explain the annealing phase of black holes within the framework of certain theories of quantum gravity, beyond what general relativity predicts.

The equation is based on the work of Caltech professor Saul Teukolsky, who developed it half a century ago to study a complex equation. propagation of waves in space-time around black holes.

The second paper, led by Sizheng Ma, presents a new approach to data analysis using filters to remove features predicted by general relativity in the black hole ring. This allows for the identification of subtle signatures that may indicate deviations from general relativity.

The combination of Dongjun Li and Sizheng Ma’s research strengthens the scientific community’s ability to investigate gravity and the fundamental nature of our universe.
