Stephen Webb: Kje so vsi Nezemljani?

Kje so vsi Nezemljani?

Vesolje je neverjetno staro, osupljivo velikansko in naseljeno z bilijoni planetov - kje so torej vsi Nezemljani? Astronom Stephen Webb ima razlago: sami smo v vesolju. V svojem razlagalnem govoru navaja izredne prepreke, ki bi jih planet moral premagati, da bi lahko bil dom izvenzemeljski civilizaciji, ter prikaže lepoto naše potencialne kozmične samote. "Tišina vesolja kriči - mi smo tisti, ki se jim je posrečilo", pravi Webb.

Despite a universe filled with trillions of planets and billions of years of opportunity, no trace of extraterrestrial civilizations has emerged. Stringent barriers—like the right planet, stable climate, emergence of life, and advanced technology—make the odds of intelligent life vanishingly small. The idea that humanity may be alone is both humbling and empowering. The very absence of a signal suggests every moment of awareness is a cosmic stroke of luck.
