We solve the equation of motion of boundary string field theory allowing<br />
generic boundary operators quadratic in $X$, and explore string theory<br />
non-perturbative vacua with massive state condensation. Using numerical<br />
analysis, a large number of new solutions are found. Their energies turn out to<br />
distribute densely in the range between the D-brane tension and the energy of<br />
the tachyon vacuum. We discuss an interpretation of these solutions as<br />
perturbative closed string states. From the cosmological point of view, the<br />
distribution of the energies can be regarded as the so-called landscape of<br />
string theory, as we have a vast number of non-perturbative string theory<br />
solutions including one with small vacuum energy.
