Mon ami Nancru,
as I said you may not believe me. It requires an "inhuman" imagination. If you understand the Relativity AND the Quantum you'll get it. All is about the bending light, the black holes and the quantifying of materials (nuclear fusion of hydrogen). According to modern physics a
black hole is an extremely quantified materials of a mass several times larger than our SUN. Imagine the SUN is squeezed into a little hole with a diameter less than the Planck's constant = 6.62606957 × 10-34... (1 power minus 34 = 1/n where n is a number with 34 zeros behind the 1)

this little tiny thing is extremely heavy and possesses an extremely strong gravity force that even light can't escape it and is swallowed by it...
