Abstract
We consider the horizon problem in a homogeneous but anisotropic unive rse (Bianchi type I). We show that the problem cannot be solved if (1) the matter obeys the strong energy condition with the positive energy density and (2) the Einstein equations hold. The strong energy condit ion is violated during cosmological inflation. (C) 1997 Elsevier Scien ce B.V.
