Black Holes Collided

Black hole mergers are among the most energetic events in space. Two black holes gradually lose energy through gravitational interactions, drawing them closer until their event horizons stretch and merge. Gravitational waves released during the process are some of the most powerful forces in the universe, with part of the black holes' mass converti...

The biggest explosions since the Big Bang set the universe in motion some 13 billion years ago produced even more energy than first thought, scientists said Wednesday.

The outskirts of spiral galaxies like our own Milky Way could be crowded with colliding black holes of massive proportions and a prime location for hunting the sources of gravitational waves, a study led by an Indian origin researcher has found.

The same instruments used in the Nobel Prize-winning discovery of gravitational waves caused by colliding black holes could help unlock the secrets of dark matter, scientists, including one of Indian origin, say.

The first gravitational wave discovery was announced in February 2016 and the second a few months later.

Gravitational waves are formed around 10 million years after two galaxies collide and their central black holes merge - about 100 times faster than previously thought, a new study has found.

Over a billion years ago, two black holes collided and merged in space. The wobble they generated - gravitational waves - hurtled through space and was heard as a "chirp" on Earth in September.

In a landmark discovery for physics and astronomy, international scientists said Thursday they have glimpsed the first direct evidence of gravitational waves, or ripples in space-time, which Albert Einstein predicted a century ago. Here are 11 facts to help you understand this development:

The researchers demonstrated that the varying signal is likely generated by the motion of the two black holes.
