"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, ...

“In the universe, an absolute vacuum is rare, and most of the universe is very low-density high-temperature plasma,” said ...

Hearing black holes like never before NASA's new project employs a technique known as sonification. It transmutes space data into sound, allowing us to conceptualise what black holes may "sound" like.

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.

They are mysterious, exciting and inescapable – black holes are some of the most exotic objects in the Universe. With gravitational-wave detectors, it is possible to detect the chirp sound that ...
