Query: Stability of matter in the accelerating spacetime   In the paper the Planck, Yukawa and Bohr forces were defined and calculated.
It was shown that the Planck force mediates the universe acceleration. The
Yukawa and Bohr forces describe the gradients of attractive strong and Coulomb
forces. It was shown that smallest, of the present day, value of Planck force
in comparison to values of the Yukawa and Bohr force guarantees the stability
of matter at T (age of universe), 10^17 s. In this paper the new particle with
mass m_(Bohr)=3.7 keV/c^2 is postulated. The range of the Coulomb force at the
atomic level is described by the formula r_(atomic)=hbar/(m_Bohr)c=0.1nm The
relation of the Planck, Yukawa, Bohr to the Schwiger force (for vacuum creation
of electron-pozyton pairs)is also outlined.
