wormholes in the Universe.

This hypothesis can explain some

observational facts and predict new effects.obse v o c s d p ed c ew e ec s.

Traversable wormhole

i h d f f h bjVarious methods of proof that some objects are WHs(or remnants of them)

a) monopole magnetic field) p gb) There is not horizon (oscillations of a radiation source: BLLac 0716+714; radiation flux with a blue Doppler shift; ; pp ;some peculiarities of the gravitational lensingc) One can see a structure at a scale smaller then gravitational ) gradius
