Now, next question is you look at neutrino experiments, right? so, you know, this is really about solar neutrinos, right? this question basically asks the following question.
00:15
You know, according to our knowledge of the nuclear reactions that's occurring in the inside the core of a sun, you expect a amount of neutrinos come out.
00:27
But actually, we observe only one third of the neutrino.
00:32
So where are the missing between neutrinos? this has been a big scientific question, right, in the past maybe a few decades.
00:40
I think it's in 1980s probably when people tend to observe the neutrinos emit from the sun.
00:47
So this neutrina looks missing.
00:50
Actually, is not, of course, not missing.
00:52
And now very widely discussed the sound rates that the neutrinos actually have, properly very little masses.
01:05
And this allows these neutrinas, you know, to fluctuate between different flavors...
