There is a curious phenomenon associated with times shortly after creation: history is finite, and processes that require time to develop cannot occur until sufficient time has elapsed. For example, the gravitational creation of sound across a valley 100 ...

Scientists confirm most distant galaxy ever
... The newly-confirmed galaxy is still unusual in its high star-formation rate, given how far away it is. But one of the previous record holders for "most distant galaxy" was making stars at 100 solar masses per year, which is in the same ballpark, meaning z8_GND_5296 is not a total fluke in its prolif ...
