  The holostar is an exact spherically symmetric solution to the field
equations of general relativity with anisotropic interior pressure. Its
properties are similar to a black hole. It has an internal temperature inverse
proportional to the square root of the radial coordinate value, from which the
Hawking temperature law follows. The number of particles within any concentric
region of the holostar's interior is proportional to the proper area of its
boundary. The holostar-metric is static throughout the whole space-time. There
are no trapped surfaces, no singularity and no event horizon. Information is
not lost. The weak and strong energy conditions are fulfilled everywhere,
except for a Planck-size region at the center.
  Geodesic motion of massive particles in a large holostar is similar to what
is observed in the universe today: A material observer moving geodesically
experiences an isotropic outward directed Hubble-flow of massive particles. The
total matter-density decreases over proper time by an inverse square law. The
local Hubble radius increases linearly over time. Geodesic motion of photons
preserves the Planck-distribution. The local radiation temperature decreases
over time by an inverse square law. The current radial position r of an
observer can be determined by measurements of the total local mass-density, the
local radiation temperature or the local Hubble-flow. The values of r
determined from the CBMR-temperature, the Hubble constant and the total
mass-density of the universe are equal within an error of 15 percent to the
radius of the observable universe.
  The holographic solution also admits microscopic self-gravitating objects
with a surface area of roughly the Planck-area and zero gravitating mass.
