Abstract
The number of superheavy particles with the mass of the Grand Unification scale with trans-Planckian energy created at the epoch of superheavy particle creation from the vacuum by the gravitation of the expanding Universe is calculated. In later collisions of these particles, gravitational radiation is radiated playing the role of bremsstrahlung for gravity. The effective background radiation of the Universe is evaluated.

The number of particles depends on the mass of the particle and leads to observable numbers of visible and dark matter particles if this mass identified with the mass of the dark matter particles is equal to the number close to the Great Unification scale [2]
In our paper [8], we obtained the following result for the gravitational radiation energy in the collision of two particles with the energy Ec.m. < EPl in the centre of mass system: 4 Ec.m
Summary
In the paper published by one of the present authors (A.A.G.) together with S.G. Mamayev [1], finite results for particle creation in the early expanding Friedmann Universe were obtained. This is because in our recent paper [8], it was found that at trans-Planckian energies of colliding particles, gravitation wave radiation is produced This radiation is much stronger than the comparable electromagnetic radiation if it could exist. In the book [11], it was mentioned that in a Friedmann expanding Universe, the number of created particles is proportional to the number of causally disconnected parts of the Universe at the Compton time of the existence of the Universe. Later, these disconnected parts are united, and collisions of particles and black holes occur. This makes possible the speculation of the possible arising of the primordial black holes leading to the active nuclei of Galaxies by this mechanism
