A Universe Not Made For Us — Carl Sagan

Our ancestors understood origins by extrapolating from their own experience; how else could they have done it! So the universe was hatched from a cosmic egg or conceived in the sexual congress of a mother god and a father god or was a kind of product of the creator’s workshop; perhaps the latest of many flawed attempts. The universe was not much bigger than what we see and not much older than our written or oral records; and nowhere very different from places that we know. We tended in our cosmologies to make thing familiar. Despite all our best efforts, we have not been very inventive. In the West, heaven is placid and fluffy; and hell is like the inside of a volcano. In many stories, both realms are governed by dominance hierarchies headed by gods or devils. Monotheists talked about the king of kings. In every culture, we imagined something like our own political system running the universe; few found the similarity suspicious. Then science came along and taught us that we are

If Heaven is Real ...

Then, perhaps the world is going to hell. I wonder how all those authors who have written NYT bestsellers would be feeling ... Tom Friedman wrote The World is Flat which went to the top of the list. I wonder if any of Richard Dawkins' books ever reached no. 1 or not. Same for Christopher Hitchens' books. And so many of the world's real talented, professional writers. I could tell them: so you've written an NYT bestseller? Well, so what! No big deal! So has 11-year-old, Mr. Heaven-returned young man. I would tell all those NASA astronauts: so what if you guys have got PhDs from CalTech and MIT and wherever! Can you write like an 11-year-old? I find the gullibility of Americans to be really scary. Perhaps the Europeans are not so gullible.

India 2030

The recent census has shown that India's population grew from 1,030 million to 1,200 million (growth of 16 percent) in the last decade. China's population increased from 1,240 million to 1,340 million (growth of 8 percent) in the same period. Assuming a growth rate of 15 percent, India's population will be 1,380 million by 2021. China's population meanwhile will reach a figure of somewhere between 1,450 million and 1,500 million. How can anyone get one's head around these enormous numbers?  How many people can anyone connect with at a personal level? How many people can a human brain remember? I don't know about others but I can speak about myself. I probably have 200 relatives. Strangely enough, I've very few friends from my school or college days. Probably 20. During those bygone days, there were social networks and the passage of time makes memories fade.  I can probably remember about 100 colleagues that I've worked with over the past fi
