MY PERSONAL EXPERIENCE ON THE SCIENTIFIC LEGACY OF THE 20 th CENTURY
Figure 20.
Neutralinos cannot aggregate into Stars since, being neutral, they lose
little energy. This would allow neutralinos to remain in a sphere concentric
with our Galactic centre. Even though they aggregated into Stars, neutralinos
could not emit light, like ordinary Stars do. Fire needs the plasma of protons
and electrons. This is why super Stars cannot emit light.
3.6. Our World and the Planck World
It is interesting to compare the density of our body and the density of
the Planck Universe. The scales of length, mass and time of the world we are
familiar with, and the scales of the Planck world are shown in Figure 21.
