The Physics of the Early Universe
But about five years ago the Hipparchus satellite began to return accurate
parallaxes for hundreds of nearby stars which led to a recalibration of the entire
distance scale. All distances outside the solar system increased by about 10% (in
fact, ...

The Aha! Moment: A Scientist's Take on Creativity
Parallax was finally found in the nineteenth century by very precise telescopic
measurements on relatively near stars. It went on to become the most exact way
of determining the distance of the nearer stars. Indeed, the Hipparchus satellite
was ...

The Role of the Sun in Climate Change
The sun is in the second layer (class G, yellow) with an absolute magnitude of
about 5. Compared with most stars, the sun displays low variability. These
measurements are derived from the Hipparchus satellite and show the relative
variability ...

which improved this by several orders of magnitude. To explore the shape and
size of our Galaxy and beyond, other methods of determining distance must be
used.

The experimental verification of Tipler's limit would, of course, have to be
astronomical, and quite possibly through some space observatory like the
Hipparchus satellite designed and planned in Europe in the 1980s. (a) (b) (c)

The new positions were derived from Hipparchus satellite data, and the charts
were prepared with computer plotting for accuracy. The earlier version "binned"
the data, while this version has a continuous progression of dot size to indicate ...
