Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which country builds an ’Artificial Sun’ 6 times hotter than Sun’s core?
A
China
B
United States
C
Japan
D
Russia
Explanation: 

Detailed explanation-1: -Reportedly, last year in December, the Experimental Advanced Superconducting Tokamak (EAST) fusion energy reactor created an artificial sun, reaching temperatures of 70 million degrees Celsius for 1, 056 seconds, which is five times hotter than the sun.

Detailed explanation-2: -Physicists from South Korea have discovered an artificial source of clean nuclear energy by initiating a strong nuclear reaction that produced temperatures seven times higher than the Sun. This discovery of creating an “artificial Sun” represented a significant advance in their study, said a report from New York Post.

Detailed explanation-3: -In the latest experiment, superheated plasma reached 126 million degrees Fahrenheit-that’s roughly five times hotter than the sun, which radiates a scorching 10, 000 degrees Fahrenheit at the surface and about 27 million degrees Fahrenheit at its core.

Detailed explanation-4: -China’s Experimental Advanced Superconducting Tokamak (EAST) set a world record by reaching temperatures exceeding 100 million degrees Celsius with its hydrogen fusion process. The resulting temperature is nearly six times hotter than our solar system’s Sun, which glows at 15 million degrees Celsius.
