A solution to smoking

Monday, May 28th, 2007

If you agree that cigarette smoking is something we’d rather be rid of I may have a possible solution:

Set a cut-off date for everyone to register their desire to have the right to buy cigarettes, issue all registered people with a card and make it illegal to buy cigarettes without one.

You could make it irrespective of age just in case you’ve go someone currently underage who is addicted.

Some people who are looking for an excuse to stop smoking will take the opportunity to decline registration as an incentive. Some people who don’t (or rarely) smoke will register just in case they want to in the future.

There will be the inevitable black market for cigarettes but I would imagine it would be tiny compared to the drug market due to the fact that starting smoking is a fairly stomach-churning business with little ‘pleasure incentive’ to pay the inflated black market prices and break the law.

Within a generation or two I would imagine only a few hobby smokers would remain and once everyone who originally registered for the card has died (presumably early) you make it illegal to buy or sell cigarettes. So few people would actually want to take up smoking that you’d not even have to bother policing it.

The “I’m not really a fascist disclaimer”:
I came up with this idea when I was a full-time smoker myself. I figured that whether I wanted to continue smoking, find an incentive to quit or, if I’d already quit, have an incentive to keep from smoking again it would be a win-win situation.

Carl Sagan reads from Pale Blue Dot

If you haven’t read Pale Blue Dot I thoroughly recommend it.

SETI - A better way?

Wednesday, May 2nd, 2007

In a nutshell: point your listening devices toward the centre of the galaxy and listen for coordinates of other intelligent civilisations.

Our solar system is in an arm of our galaxy which contains something like 500,000,000,000 stars of which we can see about 3,000 with the naked eye. When we look toward the centre of the galaxy on a clear night because we are in amongst it we see a strip of glowing haze we call the Milky Way which is in fact a lot of stars very far away all merged together.

Statistically, there is a good chance that other life has evolved in our own galaxy. In fact from what astronomers have found in the way of Earth-like planets orbiting nearby stars it looks like there is a very good chance that there are many other civilisations more advanced than our own.

SETI (at least according to Carl Sagan’s 1994 book, Pale Blue Dot) scans the sky listening for radio signals on a frequency they have assumed other intelligent life would also choose to broadcast on. Something to do with the hydrogen line. Anyway, they’ve got a lot of sky to cover and the combination of limited resources, assumptions of alien technologies and narrow frequencies they’re not having a lot of luck. The most intriguing encounters they’ve had (at least up until 1994) have all been from the direction of the centre of the galaxy. They weren’t able to pick up the signal again and it’s possible that it may have been temporarily amplified by a gravitational field or whatnot. Either way it didn’t count.

If you make the assumption that there are many, many intelligent civilisations then I would suggest that it would be a good starting place to point your listening devices toward the centre of the galaxy for the following reasons:

  • It’s the one benchmark we will all know of
  • If someone broadcasts a strong signal toward the centre then someone on the opposite side is likely to pick it up
  • All each civilisation needs to do is broadcast a list of coordinates of all known civilisations and when a new one comes on board they append their coordinates to the list
  • You then point your listening devices and transmitters at the other coordinates in the list

Galaxy

Now, keep in mind that I know next to nothing about sending radio signals through space (other than the fact that it takes many thousands of years travelling at the speed of light to even reach the centre) but if, in fact, it is possible to broadcast across these distances then it’s possible someone else may have had the same idea and we may pick up some handy information broadcast 60,000 years ago.

It’s entirely possible too that civilisations more advanced than us may have discovered faster ways of conveying information than radio waves (yes, yes, I know, nothing beats the speed of light) and would consider it an absurdity to revert back to the equivalent of carrying a letter by hand halfway around the world.
