Nobel Laureate in Physics, large bass gravitational wave, in response to the announcement by the international experimental facility research team led by the US university that Einstein succeeded in observing the gravitational wave that predicted its existence 100 years ago for the first time in the world. Takaaki Kajita, the representative of the telescope "Kagura" project, announced a comment saying "gravitational waves, a historic achievement that general relativity researchers have been waiting for."
In a comment, Professor Kajita proved that this discovery enables the study of high-density stars such as gravitational waves themselves, black holes, and neutron stars with the second-generation gravitational wave telescope including the "Kagura" under construction. I praised it.
For future research, "Kagura" is installed underground and equipped with a bass mirror, so it is highly sensitive in the band below 100 Hz and is suitable for exploring gravity wave sources in that frequency band. ..In the future, we have indicated that we will proceed with exploration aiming at a place where it is expected that there will be a coalescence event of black hole binaries where gravitational waves were observed this time.
In addition to that location, there are many celestial phenomena in the universe that should be studied using gravitational waves as an observation method, and he is enthusiastic about detecting the birth of black holes due to binary neutron star mergers.
Gravitational waves are a phenomenon in which extremely heavy substances move violently at ultra-high speeds, causing the surrounding space and the flow of time to fluctuate slightly and propagate as waves.It is released immediately after the universe is born, and is said to occur due to the coalescence of black holes and supernova explosions.Einstein predicted its existence in 1916 in the general theory of relativity, but it has never been actually detected or observed.
