Kako veliko je vesolje?
Član ekipe observatorija Pierra Augerja v Argentini, fizik prof. Dr. Danilo Zavrtanik, pravi v Dnevnikovem objektivu takole:
Vesolje je veliko dobrih trinajst milijard svetlobnih let. Dvesto milijonov svetlobnih let je za vogalom.
Ne bo držalo. Wikipedia - observable universe (misconceptions):
The age of the universe is about 13.7 billion years. While it is commonly understood that nothing travels faster than light, it is a common misconception that the radius of the observable universe must therefore amount to only 13.7 billion light-years.
