An Alternative to the other Star Trek Future

April 20th, 2009

Last week I asked whether or not the Star Trek future was possible, the part of the series that postulates human beings can set aside their prejudices, solve their problems with each other to eradicate poverty and war, and to join together to explore the universe.

Well, that exploration part is very challenging to do the Star Trek way with foreseeable technology.

Seth Shostak, of the SETI Institute, describes an alternative in Boldly Going Nowhere for the New York Times.

He says, rightly I think, that while solar system exploration is going to happen and will involve human astronauts and settlements, interstellar voyages seem out of reach for our species without technology and resources far beyond those we have today or can expect to have in the next few centuries, or longer.   (This is why for my novels, in which I want to have human characters exploring distant worlds in a few centuries, I do what Star Trek did: bring in some not-so-foreseeable technology.)

So, what is the alternative?   How can humans explore worlds orbiting distant stars, according to Shostak?

Telepresence.

The idea is that we send robots.   Tiny robots, small enough that they can be sent at some fraction of light speed (Seth suggests 10% is possible).   They do the exploring, do the mapping, picture taking, sample analysis, and tell us what those worlds are like in as much detail as their technology permits.   Then we — all of us — can virtually explore these worlds.   Stellar astronauts would not put on space suits.   They would put on virtual reality suits.

Now, the lack of real-time interactivity is a problem with this sort of experience, but if you’re like me, exploring real worlds virtually (e.g., Google Earth) or imaginary worlds (online games like World of Warcraft) can be a lot of fun.

Buzz Aldrin, when he said that science fiction had dampened enthusiasm for the space program, was right in the sense that science fiction teaches us we can have the stars, soon, and we can’t.   If human civilization is not so long-lived in the astronomical sense, we never will have them, except for perhaps virtually like this.

I’m an optimist, however, and think we will be around a long time and will develop technology advanced enough to take us to the stars, in one form or another.   That might take a while, but we’ll get there if we want to badly enough.   I want to badly enough, and I know I am not the only one.

But in the meantime we can play Star Trek virtually, and let that experience inspire more longing.
