In creating his gravitational field equations Einstein unjustifiedly assumed that inertial mass, and its energy equivalent, is a source of gravity. Denying this assumption allows modifying the field equations to a form in which a positive cosmological constant appears as a uniform density of gravitationally repulsive matter. This repulsive matter is identified as the back sides of the 'drainholes' (called by some 'traversable wormholes') introduced by the author in 1973, which attract on the high, front sides and repel more strongly on the low, back sides. The field equations with a scalar field added produce cosmological models that 'bounce' off a positive minimum of the scale factor and accelerate throughout history. The 'dark drainholes' that radiate nothing visible are hypothesized to constitute the 'dark matter' inferred from observation, their excess of negative active mass over positive active mass driving the accelerating expansion. For a universe with spatial curvature zero, and the ratio of scale factor now to scale factor at bounce equal to the Hubble radius over the Planck length, the model gives an elapsed time since the bounce of two trillion years. The solutions for negative spatial curvature exhibit early stage inflation of great magnitude in short times. Cosmic voids, filaments, and walls are attributed to separation of the back sides of the drainholes from the front, driven by their mutual attractive-repulsive interactions.
