In the Blink of an Eye: Space in an Instant

submitted by BSR

3 years 10 months 1 week ago

When we look up at night, the universe seems pretty quiet. But that perspective is an illusion; in reality, there are millions of world-shattering events happening every instant across the cosmos. This short film explores just how much is going on every moment in our ridiculously enormous universe.

It's fairly amazing how short the Stelliferous Era (the time period in which stars exist) is during the entire birth-to-death of the universe. It's roughly 10^6 - 10^14 years (one million to 100 trillion years from the Big Bang to stellar death, or a span of one million million x 8 years). This seems like a very long time, but on the universal time scale, it's not. "Matter" in the universe will exist for ~10^~125 years, or ten unquadragintillion (yes, that's a real word)

This is the equivalent (if I'm doing the math right) of the total life of the universe being a length of one mile, the entire age in which stars exist is the width of a playing card approximately one millimeter from the start.

For comparison, the atomic decay of Xenon-124 into Tellurium-124 is about 18 sextillion years (1.8 x 10^22 years), roughly 1 trillion times the current age of the universe.
