Abstract: In this announcement, for its importance, we will state a fundamental result for special relative theory of Einstein from the division by zero $z/0=0$.

Introduction
  By a natural extension of the fractions
\begin{equation}
\frac{b}{a} \tag{0.1}
\end{equation} for any complex numbers $a$ and $b$, the division by zero
\begin{equation}
\frac{b}{0}=0, \tag{0.2}
\end{equation} is clear and trivial. See $([7])$ for the recent results. See also the survey style announcements 179,185,237,246,247,250 and 252 of the Institute of Reproducing Kernels $([12], [13],[14], [15],[16],[17],[18])$. The division by zero is not only mathematical problems, but also it will give great impacts to human beings and the idea on the universe. The Institute of Reproducing Kernels is presenting various; opinions in Announcements $($many in Japanese$)$ on the universe.
   In this Announcement, for its importance, we will state a fundamental result for special relative theory of Einstein from the division by zero $z/0=0$. The contents were stated by Hiroshi Michiwaki in his memo dated on October 10, 2014 and we should state the results, more early.

1. Special relative theory of Einstein
  Einstein's discovery of the equivalence of matter/mass and energy [4] in the year 1905 lies at the core of today's modern physics. According to Albert Einstein [5], the rest-mass $m_0$, a measure of the inertia of a $($quantum mechanical$)$ object is related to the relativistic mass $m_R$ by the equation, with relative velocity $v$ and the speed $c$ of light in vacuum,
\begin{equation}
m_0 = m_R \sqrt{1 - \frac{v^2}{c^2}}. \tag{1.1}
\end{equation} Therefore, we obtain, immediately
\begin{equation}
m_R^2= m_0^2 \left(1 - \frac{v^2}{c^2}\right)^{-1}. \tag{1.2}
\end{equation} Therefore, by the division by zero, we have the surprising result for $ v = c$:
\begin{equation}
m_R = 0. \tag{1.3}
\end{equation} It seems that the modern physical common sense is then $
m_R = + \infty$.

2. A conjecture by H. Michiwaki
   As his simple result $(1.3)$ from the division by zero, Michiwaki stated his conjecture or interpretation for neutrino; neutrino are able to have small mass, because they are moved with near $c$ or $c$ velocity. Indeed, we assume that $m_0$ is the mass of neutrino at the stopped case. As the experiment, we know that the velocity of neutrino is near to $c$ or $c$. So he thought that neutrino will have small mass.
   This result was realized positively by Takaaki Kajita by experiment and he got Novel Prize in 2015.
   Furthermore, he referred to the very interesting interpretations of photon of energy and Doppler effect from the viewpoint of the division by zero in his memo.
