De ce Universul este negru? / Why is the Universe black?

Explicatia este data dupa “paradoxul lui Olbers”: lumina stelelor mai indepartate decat cele pe care le vedem nu a ajuns inca la Pamant.
The explanation is to be found in the “Olbers’ Paradox”: the light of stars more distant than the ones we see has not reached Earth yet.

Cine intreaba? Nu ii convine cuiva?
Who asks? Is someone inconvenienced by this?

Alta intrebare ar putea fi: De ce Soarele este alb?
Another question may be: Why is the Sun white?
