@taniwharugby said in Science!:
Yeah I still struggle to understand how they can say this happened so many billion years back, when, well, billions of years...yeah yeah, science, but still...guess its easier whan you have such a big window 2.229 billion years, margin of error of 5 million...pfft.
@booboo also time, in terms of light years, some more staggering numbers
A light-year is a measurement of distance and not time (as the name might suggest). A light-year is the distance a beam of light travels in a single Earth year, or 6 trillion miles (9.7 trillion kilometers).
Yeah that always makes me feel really small.
The fact the that farthest star is reachable (if still around) if we travel at the speed of light for 9,000,000,000 years.
Even if we could travel at speed of light, the fact that we could do so for a year and not be very far into the universe is staggering.
