QotD: Extraterrestrial

I usually don't care very much about the QotD, but this is close to my heart so I will answer it.

Do you believe there is intelligent life on other planets?

Definitely.  I read this book when I was a small kid, and between that and other literature by Carl Sagan and Isaac Asimov I cannot help but be convinced by pure probability.

However, they may not be very close, as they seem to have not reached us just yet.  Or maybe they have, but are wiser than we are in their dealings with less advanced civilizations.

Mexican genome study results released

Mexican media report today that the results of a gene mapping study of the Mexican population have been released. As expected, we are a mix of different ethnic groups (around 35) and in average about 65% of our genes are not of European, Asian or African origin (i.e. they are Native American), but the results tend to vary, with the highest incidence of European genes in the northern state of Sonora (58%) and the highest of African genes in the southern state of Guerrero (22%).

So, is science helping us answer the question of who are we, or not yet? 😉

The Space Elevator

We know that the world financial markets are still reeling from the China effect, but let’s think a little bit longer term.

The first time I read about the concept of space elevators was in Kim Stanley Robinson‘s excellent and highly recommended Mars trilogy. I found them again while playing Civilization IV. So the question is, what is a space elevator and why do I mention it in this blog along the rest of my musings and ruminations?

A space elevator, as this article from Space.com might make clearer, is exactly what its name denotes: a lift between the surface of our planet (or any planet) and outer space. The physics of it are rather simple, as they follow similar patters as such for geosynchronous satellites. Technologically speaking it doesn’t require the development of completely unknown technologies, but rather of areas currently on the works. Why does it matter? Simply because it makes the transport of payloads to space much more cost-effective (and furthermore, enjoys economies of scale), which basically means that once the huge initial invesment is made, space exploration (and potentially exploitation, such as asteroid mining) becomes cheap enough to be performed on a larger scale than currently.

Given that it can be argued that exploration ages spur economic growth, as was the case with the discovery of the Americas by European explorers in the 16th century, this project could be the key for humanity to regain theinitiative in its own development.

Daydreaming? Maybe. But so were the internet, automobiles and many, many other things that we now take for granted.

Carl Sagan

Wandering through Technorati while taking a break from studying International Economics I found the Carl Sagan blog-a-thon. Many in my audience will probably not have the slightest idea about who this man who died 10 years ago today was and why is he important, so check out Wikipedia.

In Mexico, where I grew up, I don’t think they ever broadcasted the Cosmos PBS series, but I was fortunate enough that my school had bought the tapes (yes, tapes, after all, I was 8 or so at the time). Also at the same age, I received as a birthday present the book “Comet” from a neighbour. It was a present I devoured, and made me realise that science can be as much fun as science fiction (even though later I discovered I don’t have the patience to be a scientist myself). During the following years I bought Cosmos, Communication with Extraterrestrial Intelligence, Pale Blue Dot and The Demon-Haunted World. I also joined the Planetary Society as a kid, with which my name went to Mars in the Mars Pathfinder (I’m not currently a member, but plan on rejoining). He is one of two persons (the other being Isaac Asimov) that planted firmly in my mind the idea that colonising other planets is what our species needs if it wants to survive (all this before global warming and the terrorist threat became the issues they are now).

He died on December 20th, 1996 after a long battle with mielodysplasia. Even though he didn’t believe in God the way I do, my prayers are with him and his family 😉 .
