Cosmological expansion of the galaxies according to
Einsteins theory (see above) suggests that the universecould have started with the Big-Bang.
The gravitational waves background was created soon after the Big-Bang. Its discoverycould be the next prove for the reality of the event. The gravitational waves are also
produced in astrophysical phenomena such as: coalescing binaries of the neutron starsand the black holes. There exists a space project LISA to detect such waves (see above).

Szczecin Cosmology Group carries on advanced research in large-scale structure of the universe and its past and future evolution. The basic framework of the research isnot only general relativity but also more avangardous unification of interactions theories such as superstring and M-theory. The group has a broad international
collaboration, e.g. with prof. John D. Barrow (see top right) from Cambridge University a mathematician, the 2005 Templeton Prize winner and the author of manyworlwide-known popular books in physics and cosmology. We also collaborate with rev. prof. Michael Heller (see top right) from Vatican Observatory and Interdisciplinary
Kopernik Center in Krakw the 2007 Templeton Prize winner a physicist, a philosopher and a theologian.The members of the group are: prof. M.P. Dbrowski, prof.. J. Garecki, prof.. J. Stelmach, A. Balcerzak (M. Sc.) and Dr. T. Denkiewicz.
For full info about the group see: http://cosmo.fiz.univ.szczecin.pl.
One of the key assumptions of thesuperstring theory is that all the
elementary particles at theextremely small scale are not pointobjects, but rather extended and
continuously vibrating strings. Thescattering of the two strings can be
described by a pants diagram
(see right).
The most convincingevidence for the reality of
the Big-Bang was thediscovery of the
electromagnetic cosmicmicrowave background
(see left). About thefuture evolution of theuniverse one is able to
learn by observing theexploding supernovae
(see right).

I. Anthropic aspects of
cosmology.
1. The man in the Universe.
Cosmological Anthropic Principles.
Masses and sizes of the objects in
the Universe are not arbitrary.
What does it mean?

Besides, the physical world is full of various
coincidences,which are required for life to exist.
Examples (out of hundreds): water shrinks
at 0-4 Celcius degree, the Earth has the onlyone and quite large natural satellite due to
which it does not wobble chaotically,
electrons are light enough compared tothe nuclei etc.
