00:00One neutrino can change to another neutrino at a flight.
00:13So such a special property may have a big impact to how nature works and how the universe
00:25evolves.
00:26So we don't know the answer yet.
00:29That's why we need to experiment to measure the property of the neutrino and get the answer
00:36of the fundamental rules of our nature.
00:39So we have started the construction about 10 years ago and we spent a lot of time on
00:44the civil construction and now we finally approached the end of the construction and
00:50we plan to formally start the data taking next year.
00:57And in six years we will get some answer on our primary goal to measure the neutrino
01:02mass ordering and we plan to run this experiment for 30 years.
01:08From basic research to application there are quite a distance.
01:12We need several steps.
01:14It may be not useful and even if it's useful it may take a long time.
01:19So that's not our primary goal for application but it may have some application.
01:27The one in the U.S. will be six years behind us and the one in France and Japan will be
01:36two or three years later than us.
01:39So we believe that we can get the result of mass hierarchy ahead of everybody.
