Born too late to explore the Earth, born too early to explore the galaxy, we're the middle children of history. "There are places in and around our great cities where the natural world has all but disappear, you can make out streets and sidewalks, autos, parking garages, advertising billboards, monuments in glass and steel, but not a tree or a blade of grass or any animal besides, of course, the humans… there are lots of humans.
Only when you look straight up through the skyscraper canyons can you make out a star, or a patch of blue, reminders of what was there long before humans came to be. Is not hard, going to work every day in such a place, to be impressed with ourselves. How we’ve transformed the earth for our benefit and convenience! But a few hundred miles, up or down, there are no humans, our impact on the universe is null…
In the last 10.000 years, an instant in our long history, we’ve abandoned the nomadic life, we’ve domesticated the plants and animals… why chase the food when you can make it come to you? For all its material advantages, the sedentary life has left us edgy, unfulfilled. Even after 400 generations in villages and cities, we haven’t forgotten.
There are now people on every continent and the remotest islands, from pole to pole, from mount Everest to the Dead Sea, on the ocean bottoms and even, occasionally, in residence 200 miles up, humans, like the gods of old, are living in the sky.
These days, there seems to be nowhere left to explore. Victims of their very success, the explorers, now, pretty much stay home.
Maybe it’s a little early, maybe the time is not quite yet, but those other the worlds, promising untold opportunities, beckon.
Just now, there are great many matters that are pressing in on us, that compete for the money it takes to send people to other worlds. Should we solve those problems first? Or are they a reason for going?
Our planet and our solar system are surrounded by a new world ocean, the depths of space… it is no more impassable than the last."
"The near side of a galaxy is tens of thousands of light-years closer to us than the far side; thus we see the front as it was tens of thousands of years before the back. But typical events in galactic dynamics occupy tens of millions of years, so the error in thinking of an image of a galaxy as frozen in one moment of time is small." - Carl Sagan, Cosmos.
🌌One of my favorite things to watch as a kid was his series on the universe. 🌌
I would think the reasons why such pseudoscientific thinking plagues modern society as Carl Sagan very presciently predicted in #DemonHauntedWorld is the very unfortunate inculcation that we have to "respect" other people's beliefs. Apparently, criticizing credulous belief offends many people but disgracing the integrity of scientific thought offends no one. It seems to me that you are more likely to offend for pointing out pseudo-scientific ideas than a woo peddler is for misrepresenting empirical reality. Ideas should not be shielded from scientific judgement. Ideas should not be absolved of the intellectual responsibility of a rational/scientific explanation. And, indeed, when you subject beliefs to the rigorous standards of scientific scrutiny, no disrespect is meant to the individual(s) holding them. Imagine two competing scientists having to respect each other's hypotheses when, undoubtedly, one of them is wrong. In assessing the veracity of a hypothesis, no scientist would want shield it from criticism, evaluation, or ridicule because that would make it extremely hard to verify. Criticizing an idea can sometimes illuminate it and if any one belief is so tremulous that criticizing it can often be taken as offensive by those who hold it, then perhaps it is not good enough. People have rights. Ideas don't. #sagan#carlsagan#reason#science#empiricism#saganism#superstitions
