Million vs. Trillion
To get an idea how much bigger one trillion is than one million, ponder this: A million seconds is 12 days; a trillion seconds is 32,000 years.
Now get this: It is estimated that in the Universe there are a trillion stars for every human being on planet Earth.
In the grand scheme of things, quite humbling, as we are pretty insignificant.
“The size and age of the Cosmos are beyond ordinary human understanding. Lost somewhere between immensity and eternity is our tiny planetary home. In a cosmic perspective, most human concerns seem insignificant, even petty. And yet our species is young and curious and brave and shows much promise. In the last few millennia we have made the most astonishing and unexpected discoveries about the Cosmos and our place within it, explorations that are exhilarating to consider. They remind us that humans have evolved to wonder, that understanding is a joy, that knowledge is prerequisite to survival. I believe our future depends on how well we know this Cosmos in which we float like a mote of dust in the morning sky.”
- Carl Sagan
I will take any excuse to quote Carl Sagan.
