"We would need to consider the possibility that the source was created (or trapped as a primordial black hole) by a highly advanced technological civilization," Harvard's Avi Loeb writes.

Caltech simulations reveal what happens when black holes collide with neutron stars—violent cracking, intense shock waves, ...

Now, after decades of pondering primordial black holes, scientists sound genuinely optimistic about the possibility of detecting them. There’s been a surge of interest in the field.

Washington: US space agency NASA has recorded an eerie audio clip that captures sound waves coming from near a supermassive black hole situated 250 million light years away. The acoustic waves ...

The black hole is located at the heart of the Perseus galaxy cluster, and the resulting audio is an unsettling, howling sound. In space, we can't naturally hear sound, but sound waves do exist.

Mysterious and inescapable: Black holes are some of the most exotic objects in the Universe. Researchers at HITS, Germany, predict that the chirp sound that two black holes produce when they merge ...

Black holes are surprisingly simple objects. In the general theory of relativity, which is the framework we use to understand all things gravity, you only need three numbers to completely and totally ...

The process involves sound waves being extracted radially, outwards from the center of the black hole, and then transposed up by 57 to 58 octaves to make them audible to the human ear. While the audio ...
