Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following team has announced their second detection of gravitational waves, the flexing of space and time caused by the black hole collision
A
NASA team
B
ISRO team
C
JAXA team
D
LIGO team
Explanation: 

Detailed explanation-1: -LIGO scientists waited until now to announce the second detection because they had to make sure that it was real, and that it was caused by a black hole collision, team members said.

Detailed explanation-2: -The two black holes were growing in tandem near the center of the coalescing galaxy resulting from the merger. They met when their host galaxies, known as UGC 4211, collided. One is 200 million times the mass of our sun, while the other is 125 million times the mass of our sun.

Detailed explanation-3: -Albert Einstein predicted the existence of gravitational waves in 1916 in his general theory of relativity.

Detailed explanation-4: -’ Gravitational waves are vibrations in the fabric of spacetime caused by the acceleration of objects in the universe. Their existence was predicted 100 years ago by Albert Einstein but this is the first time they have been detected.

Detailed explanation-5: -It is possible for two black holes to collide. Once they come so close that they cannot escape each other’s gravity, they will merge to become one bigger black hole. Such an event would be extremely violent.
