Discovering new gravitational waves from two black holes collides 3 billion light-years away

New gravitational wave signals are produced when two black holes are 3 billion light-years away facing each other and eventually merging into a new one discovered by German scientists in the early morning of January 4.

Scientists at the Interfering Laser Wave Observatory (LIGO) have recorded a new gravitational signal called GW170104, which came from the merger of two black holes 3 billion light-years from Earth. This gravitational wave signal is far more distant than the two gravitational wave signals that LIGO once discovered.

Scientists have discovered phenomena like black holes merged by studying distortions in space and time.

The two black holes in the collision had masses of 31.2 and 19.4, respectively. After the collision, a new, heavy black hole equivalent to 48.7 Sun, was born. The lost mass is converted into gravitational waves.

Compared to the black hole formed by the previous two mergers that scientists have observed, this newly formed black hole is considered to have medium mass. According to scientists, mid-range black holes are gradually gaining popularity in the universe.

The majority of black holes are born from a dead star, which is considerably lighter in weight than the newly created black hole this time. At the center of the galaxies, there are a number of super-large black holes, weighing millions to billions of solar masses.

The gravitational wave signal from the merger has just been discovered that two black holes do not rotate on the same axis, they are only paralleled at the end of the life cycle.

From more than a century ago, in 1916 Einstein had predicted the existence of gravitational waves and assumed that it was not scattered like light.

Upon discovering this gravitational wave, scientists will study the possibility of scattering gravitational waves to determine the limit in Albert Einstein's theory of relativity. LIGO's measurements have not been in conflict with Einstein's conclusions.

At the same time, the discovery of this new gravitational wave also indicates the diversity of black holes in the universe. Accordingly, in the future LIGO will conduct systematic studies of black holes in the universe instead of the single phenomenon studies as before.
